Dual Non-Inverting Power Driver

FEATURES

DESCRIPTION

•

3.0A Peak Current Totem Pole

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.

Output

•

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 effect the behav-

ior 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 MINI DIP and 16-pin

“bat-wing” DIP packages for commercial operation over a 0^oC to +70^oC tem-

perature range and industrial temperature range of -25^oC to +85^oC

respectively. For operation over a -55^oC to +125^oC temperature range, the

UC1708 is available in hermetically sealed 8-pin MINI CDIP, 16 pin CDIP

and 20 pin CLCC packages. Surface mount devices are also available.

⁽¹⁾The marketing status values are defined as follows:

ACTIVE: Product device recommended for new designs.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in

a new design.

PREVIEW: Device has been announced but is not in production. Samples may or may not be available.

OBSOLETE: TI has discontinued the production of the device.

Eco Plan

The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS

no Sb/Br)

please check

http://www.ti.com/productcontent for the latest availability information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered

at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame

retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

(3)
