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.

Enable and Shutdown Functions

Wide Input Voltage Range

The UC3708 and UC2708 are available in plastic 8-pin MINIDIP and 16-

pin "bat-wing" DIP packages for commercial operation over a 0 C to

ESD Protection to 2kV

+70 C temperature range and industrial temperature range of -25 C to

+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.
