DESCRIPTION

The UC1708 family of power drivers is made with a high-speed, high-voltage, Schottky process to interface

control functions and high-power switching devices – particularly power MOSFETs. Operating over a 5 V to 35 V

supply range, these devices contain two independent channels. The A and B inputs are compatible with TTL and

CMOS logic families, but can withstand input voltages as high as V_IN. Each output can source or sink up to 3 A

as long as power dissipation limits are not exceeded.

Although each output can be activated independently with its own inputs, they can be forced low in common

through the action of either a digital high signal at the Shutdown terminal or by forcing the Enable terminal low.

The Shutdown terminal will only force the outputs low, it will not effect the behavior of the rest of the device. The

Enable terminal effectively places the device in under-voltage lockout, reducing power consumption by as much

as 90%. During under-voltage and disable (Enable terminal forced low) conditions, the outputs are held in a

self-biasing, low-voltage, state.

The UC3708 and UC2708 are available in plastic 8-pin MINI DIP and 16-pin bat-wing DIP packages for

commercial operation over a 0°C to 70°C temperature range and industrial temperature range of –25°C to 85°C

respectively. For operation over a –55°C to 125°C temperature range, the UC1708 is available in hermetically

sealed 8-pin MINI CDIP, 16 pin CDIP and 20 pin CLCC packages. Surface mount devices are also available.
