DESCRIPTION

The UC1706 family 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: They provide an optional single-ended to push-pull conversion

through the use of an internal flip-flop driven by double-pulsesuppression

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.
