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 1.5A 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 5V to
40V.
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.

ABSOLUTE MAXIMUM RATINGS
Note: All voltages are with respect to the four ground pins
which must be connected together. All currents are positive
into, negative out of the specified terminal. Digital Drive can exceed 5.5V if input current is limited to 10mA. Consult Packaging section of Databook for thermal limitations and
considerations of package.
