BLOCK DIAGRAM
DESCRIPTION
The UC1708 family of power drivers is made with a high-speed, high-
voltage, Schottky process to interface control functions and high-power
switching devices – particularly power MOSFETs. Operating over a 5 to
35 volt supply range, these devices contain two independent channels.
The A and B inputs are compatible with TTL and CMOS logic families,
but can withstand input voltages as high as VIN. Each output can source
or sink up to 3A as long as power dissipation limits are not exceeded.
Although each output can be activated independently with its own inputs,
they can be forced low in common through the action of either a digital
high signal at the Shutdown terminal or by forcing the Enable terminal
low. The Shutdown terminal will only force the outputs low, it will not ef-
fect the behavior of the rest of the device. The Enable terminal effectively
places the device in under-voltage lockout, reducing power consumption
by as much as 90%. During under-voltage and disable (Enable terminal
forced low) conditions, the outputs are held in a self-biasing, low-voltage,
state.
The UC3708 and UC2708 are available in plastic 8-pin MINIDIP and 16-
pin "bat-wing" DIP packages for commercial operation over a 0oC to
+70oC temperature range and industrial temperature range of -25oC to
+85oC respectively. For operation over a -55oC to +125oC temperature
range, the UC1708 is available in hermetically sealed 8-pin MINIDIP and
16 pin DIP packages. Surface mount devices are also available.
Note: Shutdown feature available only in JE , NE or DW packages.
