Dual Channel Power Driver
FEATURES
DESCRIPTION
• Two independent Drivers
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.
• 1.5A Totem Pole Outputs
• Inverting and Non-Inverting Inputs
• 40ns Rise and Fall into 1000pF
• High-Speed, Power MOSFET
Compatible
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 sig-
nal at the Shutdown terminal or a differential low-level analog signal. The
Shutdown command from either source can either be latching or not, de-
pending on the status of the Latch Disable pin.
• Low Cross-Conduction Current Spike
• Analog Shutdown with Optional Latch
• Low Quiescent Current
Supply voltage for both VIN and VC can independently range from 5V to
40V.
• 5V to 40V Operation
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 her-
metically sealed cerdip for –55°C to +125°C operation. Also available in
surface mount DW, Q, L packages.
• Thermal Shutdown Protection
• 16-Pin Dual-In-Line Package
• 20-Pin PLCC and CLCC Package
