Package: SOIC 8 Pin Type

Manufacturer: Texas Instruments

Pinouts:

Description

The UCC27531, UCC2753x family of devices are single-channel, high-speed, gate drivers capable of effectively driving MOSFET and IGBT power switches by up to 2.5-A source and 5-A sink (asymmetrical drive) peak current. Strong sink capability in asymmetrical drive boosts immunity against parasitic Miller turn-on effect.

The UCC2753x device can also feature a split-output configuration where the gate-drive current is sourced through OUTH pin and sunk through OUTL pin. This pin arrangement allows the user to apply independent turn-on and turn-off resistors to the OUTH and OUTL pins respectively and easily control the switching slew rates.

Features

• Low-cost gate driver (offering optimal solution for driving FET and IGBTs)

• Superior replacement to discrete transistor pair drive (providing easy interface with controller)

• TTL and CMOS compatible input logic threshold (independent of supply voltage)

• Split output options allow for tuning of turnon and turnoff currents

• Inverting and noninverting input configurations

• Enable with fixed TTL compatible threshold
