UC3706 Dual Output Driver IC Chip

UC3706(Dual Output Driver)

Introduction

The UC1706/UC2706/UC3706 of output drivers are made with a high-speed Schottky process to interface between low-level control functions and high-power switching devices – particularly power MOSFET’s. These devices implement three generalized functions as outlined below.

First: They accept a single- ended, low-current digital input of either polarity and process it to activate a pair of high-current, totem pole outputs which can source or sink up to 1.5A each.

Second: The UC1706/UC2706/UC3706 provide an optional single-ended to push-pull conversion through the use of an internal flip-flop driven by double-pulse-suppression logic. With the flip-flop disabled, the outputs work in parallel for 3.0A capability.

Third: Protection functions are also included for pulse -by-pulse current limiting, automatic deadband control, and thermal shutdown.

These devices are available in a two-watt plastic “bat-wing” DIP for operation over a 0°C to 70°C temperature range and, with reduced power,in a hermetically sealed cerdip for -55°C to + 125°C operation. Also available in surface mount Q and L packages.
