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 de-
vices implement three generalized functions as outlined below.
Single-Ended to Push-Pull Conversion First: They accept a single-ended, low-current digital input of either polar-

ity 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
Low Cross-Conduction Current Spike 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.

Thermal Shutdown Protection
16-Pin Dual-In-Line Package
These devices are available in a two-watt plastic “bat-wing” DIP for op-
eration 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 avail-
able in surface mount Q and L packages.
