High Performance 100 V  
Smart Power Stage Module  
FDMF2011  
PQFN36 6X7.5, 0.5P  
CASE 483BB  
General Description  
The FDMF2011 is a compact 100 V Smart Power Stage (SPS)  
module that is a fully optimized for use in high current switching  
applications. The FDMF2011 module integrates a driver IC plus two  
N−channel Power MOSFETs into a thermally enhanced, 6.0 mm x  
7.5 mm
 
PQFN package. The PQFN packaging provides very low  
package inductance and resistance improving the current handling  
capability and performance of the part. With an integrated approach,  
the complete switching power stage is optimized with regards to driver  
and MOSFET dynamic performance, system parasitic inductance, and

FUNCTIONAL DESCRIPTION  
PWM Input Stage  
The FDMF2011 is a non−inverting 100 V half−bridge  
Smart Power Stage (SPS) module. The module packages a  
driver IC die along with pair of equally sized (matched  
The FDMF2011 incorporates a PWM input gate drive  
design, where the low side drive output (LO) and high side  
drive output (HO) are controlled through independent PWM  
inputs (LI and HI, respectively).

(Standard gate thresholds refer to

).  
The module (driver IC) can be used with TTL compatible  
input signals. The input signals can also be driven with  
voltage levels that are lower than the VDD supply level. The  
VDD supply level does NOT affect the input threshold  
levels (VIH and VIL).  
The FDMF2011 module provides separate power input  
pins; the power stage input (VIN) and the gate driver input  
(VDD). The power stage input (VIN) accepts a wide  
operating from 3 V to 80
V
,
w
hile the gate driver input  
(VDD) requires 10 V to 20
V
.
T
he module accepts TTL  
compatible inputs (HI/LI) along with anti−cross conduction  
circuitry to protect against over−lapping PWM (HI/LI)  
pulses. The module (driver IC) also implements UVLO  
circuitry in both the VDD−VSS and BOOT−PH power  
domains.  
Power−Up and UVLO Operation  
UVLO circuits are implemented in both the VDD−VSS  
and HB−PH power domains. During power−up, the  
VDD−VSS UVLO circuit forces HO and LO low until the  
VDD supply voltage exceeds the UVLO rising threshold  
(9.4 V typ.). The module (driver IC) will begin responding  
to PWM pulses once VDD exceeds the UVLO threshold.  
The UVLO circuit does contain hysteresis (~0.6 V) to  
prevent noise from interfering with normal operation.  
An additional UVLO circuit is implemented on the HB−PH  
pins which will hold HO low until HB−PH > 9.4 V (typ.).  
The HB−PH UVLO also incorporates hysteresis (~0.6 V).

The driver IC output stage is designed to drive a pair of  
N−channel MOSFETs. The driver outputs (LO, HO) are

(LI, HI respectively). The LO and HO outputs are capable  
of sinking and sourcing up to 0.65/0.35

respectively.

The driver output stage is also capable of providing a rail  
(VDD) to rail (VSS) output voltage level when driving the  
Power MOSFETs. Depending on the end application, the  
output voltage level can be set to aide in optimizing  
MOSFET and driver IC power losses. The driver output  
voltage level can also be used to help adjust SW node edge  
rates.

FDMF2011  
APPLICATION INFORMATION  
The FDMF2011 is designed as a non−inverting power  
stage, where the Power MOSFET response (SW node) is  
designed to follow to HI/LI commands. The device is  
well−suited to be used in a wide variety of applications, such  
as: Half and Full−Bridge DC−DC converters, Active Clamp  
Forward converters, rectifier circuits, and motor drive  
power stages. However, various applications and topologies  
can place unique stresses on the module. There are a few  
basic power−stage requirements needed to ensure proper  
operation.  
Module Power Dissipation  
As previously mentioned, the FDMF2011 is a multi−chip  
module (MCM). The module consists of three die (HS  
MOSFET, LS MOSFET and driver IC). Each die dissipates  
heat in normal operation resulting from power loss. The  
power MOSFETs can generate power loss from conduction  
and switching losses while the driver IC dissipated loss from  
bias, boot diode conduction and from the driver output stage  
sinking and sourcing power MOSFET gate currents and  
operating frequency. The amount of heat dissipated by any  
die is largely dependent on the operating conditions. The  
close physical placement of the three die inside of the  
package translates into strong thermal coupling between die.  
Ideally, a thermal camera should be used to monitor the  
FDMF2011 during the engineering development phase.  
This can help ensure the module operates within the absolute  
maximum ratings specified in this datasheet.  
Figure 65. H−bridge Motor Drive  
FDMF2011 Power Dissipation  
The maximum motor drive current can be obtained from  
estimating total power dissipation of motor driver. There are  
a number of factors which limit actual current level such as  
motor ratting, driver IC, PCB construction, ambient  
temperature and given application. All of power dissipation  
components must be considered to get reliable operation at  
the specific application. There is obvious power dissipations  
listed below in single H−bridge motor application.

The FDMF2011 can reliably operate while driving  
various load impedances. However, the relatively large  
number of applications can result in the module operating in  
various modes. Common applications such as switching  
power converters and motor drives can place the FDMF2011  
into different operating modes. The various operating  
modes will change the response of the MOSFET voltage and  
current stresses and power losses as well as the gate driver  
dead time response. A few operating modes are
listed

H−bridge Motor Drive  
In this operating mode, it allows bi−directional current  
flow through motor by enabling diagonal MOSFETs to  
make current flow in one or the other direction. Inductor  
current will not tolerate abrupt changes either when charged  
or discharged and alternate path is required to protect  
switches during dead−time. The path can be made either  
MOSFET body−diode conducting as soon as switches are  
disabled or enabling opposite high−side or low−side switch  
to carry the recirculation current while avoiding  
shoot−through. Utilizing MOSFET channel is often much  
more efficient way to handle the decaying current due to  
lower conduction power loss than body−diode forward drop  
loss.

Continuous Current Flowing Out of SW Node  
Continuous current flowing out of the module SW node  
is typical of a heavily loaded switched−mode power stage  
that is operating in a synchronous buck converter topology.  
In this mode, the power stage is supplying current from VIN  
into an inductive load.

shows and example of  
a synchronous buck convert operating in CCM with positive  
inductor current.  
Figure 67. Synchronous Boost Converter  
Operating in CCM  
From a module perspective, the main difference here  
versus the previous (buck) operating mode is that this  
situation will cause the LS FET (Q2) to act as the control  
MOSFET and hard switch while the HS FET (Q1) acts as a  
synchronous rectifier and undergoes soft switching with  
body diode recovery. This type of operation can drastically  
change power losses dissipated in Q1 and Q2 versus buck  
operating mode.

external gate resistors. The module provides pins for the HO

(Power MOSFET gate pins). Resistors can be placed in  
series with the MOSFET gate to control the SW node edge  
rates.
