Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply  
functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If  
used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully  
functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

8 Detailed Description  
8.1 Overview  
The TPS16530 is a 58-V industrial eFuse. The device provides robust protection for all systems and applications  
powered from 4.5 V to 58
V
.
F
or hot-pluggable boards, the device provides hot-swap power management with  
in-rush current control and programmable output voltage slew rate features using the dVdT pin. Load, source  
and device protections are provided with many programmable features including overcurrent and undervoltage.  
The precision overcurrent limit (±7% at 6 A) helps to minimize over design of the input power supply, while the  
fast response short circuit protection 1 µs (typical) immediately isolates the faulty load from the input supply  
when a short circuit is detected.  
The device provides precise monitoring of voltage bus for brown-out and overvoltage conditions and asserts fault  
signal for the downstream system. The device’s overall threshold accuracy of 2% ensures tight supervision of  
bus, eliminating the need for a separate supply voltage supervisor chip.  
Additional features of the TPS16530 include:  
•
±6% current monitor output (IMON) for health monitoring of the system  
•
A choice of latch off or automatic restart mode response during current limit and thermal fault using MODE  
pin  
•
PGOOD indicator output  
•
Over temperature protection to safely shutdown in the event of an overcurrent event  
•
De-glitched fault reporting for faults  
•
Enable and Disable control from an MCU using EN pin  
•
Low power shutdown using SHDN pin

8.3 Feature Description  
8.3.1 Hot Plug-In and In-Rush Current Control  
The devices are designed to control the inrush current upon insertion of a card into a live backplane or other  
“hot” power source. This limits the voltage sag on the backplane
’
s supply voltage and prevents unintended  
resets of the system power. The controlled start-up also helps to eliminate conductive and radiative  
interferences. An external capacitor connected from the dVdT pin to GND defines the slew rate of the output  
voltage at power-on. The fastest output slew rate of 24V/500 µs can be achieved by leaving dVdT pin floating.  
The inrush current can be calculated using

The TPS16530 device feature ILIM pin short and open fault detection and protection. The internal FET is turned  
OFF when ILIM pin is detected short or open to GND and it remains OFF till the ILIM pin fault is removed.  
8.3.3.2 Short Circuit Protection  
During a transient output short circuit event, the current through the device increases rapidly. As the current-limit  
amplifier cannot respond quickly to this event due to its limited bandwidth, the device incorporates a fast-trip  
comparator. The fast-trip comparator architecture is designed for fast turn OFF t

turns back on slowly, allowing the current-limit loop to regulate the output current to I

The fast-trip comparator architecture has a supply line noise immunity resulting in a robust performance in noisy  
environments. This performance is achieved by controlling the turn OFF time of the internal FET based on the

8.3.3.2.1 Start-Up With Short-Circuit On Output  
When the device is started with short-circuit on the output, the current begins to limit at I

(OL)

. Due to high power  
dissipation of VIN × I

within the device the junction temperature increases. Subsequently, the thermal  
regulation control loop limits the load current to regulate the junction temperature at T

a duration off t

8-7. IMON Response During a Load Step  
The IMON pin must not have a bypass capacitor to avoid delay in the current monitoring information.  
8.3.5 FAULT Response (FLT)  
The FLT open-drain output asserts (active low) under the faults events such as undervoltage, overload, current  
limiting, ILIM pin short and thermal shutdown conditions. The device is designed to eliminate false reporting by  
using an internal “de-glitch” circuit for fault conditions without the need for an external circuitry. FLT can be left  
open or connected to GND when not used.  
8.3.6 Power Good Output (PGOOD)  
The devices feature an open drain Power good (PGOOD) indicator output. PGOOD can be used for enable and  
disable control of the downstream loads like DC/DC converters. PGOOD goes high when the internal FET
’
s  
gate is enhanced. It goes low when the internal FET turns OFF during a fault event or when SHDN is pulled low  
or when EN is pulled high. There is a deglitch of 11.5 msec (typical), t

PGOODR

, at the rising edge and 10 msec  
(typical), t

PGOODF

, on falling edge. PGOOD is a rated for 58 V and can be pulled to IN or OUT through a resistor.  
8.3.7 IN, P_IN, OUT and GND Pins  
Connect a minimum of 0.1-µF capacitor across IN and GND. Connect P_IN and IN together. Do not leave any of

The TPS16530 eFuse is designed for the supply voltage range of 4.5 V
≤
V

IN

≤
58
V
.
I
f the input supply is  
located more than a few inches from the device, TI recommends an input ceramic bypass capacitor higher than  
0.1
μ
F
.
P
ower supply must be rated higher than the current limit set to avoid voltage droops during overcurrent  
and short circuit conditions.  
10.1 Transient Protection  
In case of short circuit and overload current limit, when the device interrupts current flow, input inductance  
generates a positive voltage spike on the input and output inductance generates a negative voltage spike on the  
output. The peak amplitude of voltage spikes (transients) depends on the value of inductance in series to the  
input or output of the device. These transients can exceed the

of the device if steps  
are not taken to address the issue.  
Typical methods for addressing transients include:  
•
Minimizing lead length and inductance into and out of the device  
•
Using large PCB GND plane  
•
Use of a Schottky diode across the output and GND to absorb negative spikes  
•
A low value ceramic capacitor (C

(IN)

to approximately 0.1
μ
F) to absorb the energy and dampen the  
transients.  
The approximate value of input capacitance can be estimated with

Some applications may require additional Transient Voltage Suppressor (TVS) to prevent transients from  
exceeding the

of the device. These transients can occur during positive and  
negative surge tests on the supply lines. In such applications, TI recommends to place at least 1 µF of input  
capacitor.  
The circuit implementation with optional protection components (a ceramic capacitor, TVS and schottky diode) is  
shown in

11 Layout  
11.1 Layout Guidelines  
•
For all the applications, a 0.1 µF or higher value ceramic decoupling capacitor is recommended between IN  
terminal and GND.  
•
High current carrying power path connections must be as short as possible and must be sized to carry at  
least twice the full-load current. See

and

for a typical PCB layout example.  
•
Locate all the TPS16530 device support components R

(ILIM)

, C

(dVdT)

, R

(IMON)

, UVLO resistors close to the  
device pin. Connect the other end of the component to the GND with shortest trace length.  
•
The trace routing for the R

(ILIM)

component to the device must be as short as possible to reduce parasitic  
effects on the current limit accuracy. These traces must not have any coupling to switching signals on the  
board.  
•
Protection devices such as TVS, snubbers, capacitors, or diodes must be placed physically close to the  
device they are intended to protect and routed with short traces to reduce inductance. For example, a  
protection Schottky diode is recommended to address negative transients due to switching of inductive loads,  
and it must be physically close to the OUT and GND pins.  
•
Thermal Considerations: When properly mounted, the PowerPAD package provides significantly greater  
cooling ability.
T
o
o
perate at rated power, the PowerPAD must be soldered directly to the board GND plane  
directly under the device. Other planes, such as the bottom side of the circuit board, can be used to increase  
heat sinking in higher current applications.
