Dual Non-Inverting Power Driver  
FEATURES  
DESCRIPTION  
3.0A Peak Current Totem Pole  
Output  
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.  
5 to 35V Operation  
25ns Rise and Fall Times  
25ns Propagation Delays  
Thermal Shutdown and Under-  
Voltage Protection  
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.

Wide Input Voltage Range  
The UC3708 and UC2708 are available in plastic 8-pin MINIDIP and 16-

+85 C respectively. For operation over a -55 C to +125 C temperature  
range, the UC1708 is available in hermetically sealed 8-pin MINIDIP and  
16 pin DIP packages. Surface mount devices are also available.
