description

The TPS28xx series of dual high-speed MOSFET

drivers are capable of delivering peak currents of 2 A

into highly capacitive loads. This performance is

achieved with a design that inherently minimizes

shoot-through current and consumes an order of

magnitude less supply current than competitive

products.

The TPS2811, TPS2812, and TPS2813 drivers include

a regulator to allow operation with supply inputs

between 14 V and 40 V. The regulator output can power

other circuitry, provided power dissipation does

not exceed package limitations. When the regulator is not required, REG_IN and REG_OUT can be left disconnected

or both can be connected to V

or GND.

The TPS2814 and the TPS2815 have 2-input gates that give the user greater flexibility in controlling the MOSFET.

The TPS2814 has AND input gates with one inverting input. The TPS2815 has dual-input NAND gates.

TPS281x series drivers, available in 8-pin PDIP, SOIC, and TSSOP packages operate over a ambient temperature

range of −40°C to 125°C.

SLVS132F − NOVEMBER 1995 − REVISED OCTOBER 2004 APPLICATION INFORMATION The TPS2811, TPS2812 and TPS2813 circuits each contain one regulator and two MOSFET drivers. The regulator can be used to limit VCC to between 10 V and 13 V for a range of input voltages from 14 V to 40 V, while providing up to 20 mA of dc drive. The TPS2814 and TPS2815 both contain two drivers, each of which has two inputs.
