DESCRIPTION
The UC1707 family of power drivers is made with a high-speed Schottky process to interface between low-level
control functions and high-power switching devices–particularly power MOSFETs. These devices contain two
independent channels, each of which can be activated by either a high or low input logic level signal. Each output
can source or sink up to 1.5 A as long as power dissipation limits are not exceeded.
Although each output can be activated independently with its own inputs, it can be forced low in common through
the action either of a digital high signal at the Shutdown terminal or a differential low-level analog signal. The
Shutdown command from either source can either be latching or not, depending on the status of the Latch
Disable pin.
Supply voltage for both VIN and VC can independently range from 5 V to 40 V.
These devices are available in 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 DW, Q, L packages.
