The UCC27531-Q1 is a single-channel, high-speed, gate driver capable of effectively driving MOSFET and IGBT power switches by using 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 UCC27531-Q1 device can also feature a split-output configuration where the gate-drive current is sourced through the OUTH pin and sunk through the 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.

The driver has rail-to-rail drive capability and an extremely small propagation delay of typically 17 ns.

The input threshold of UCC27531-Q1 is based on TTL and CMOS compatible low-voltage logic, which is fixed and independent of VDD supply voltage. The 1-V typical hysteresis offers excellent noise immunity.

The driver has the EN pin with fixed TTL compatible threshold. The EN pin is internally pulled up; pulling the EN pin low disables driver, while leaving it open provides normal operation. The EN pin can be used as an additional input with the same performance as the IN pin.

Leaving the input pin of driver open holds the output low. The logic behavior of the driver is shown in the application diagram, timing diagram and input and output logic truth table.

Internal circuitry on the VDD pin provides an UVLO function that holds output low until VDD supply voltage is within operating range.

The UCC27531-Q1 driver is offered in a 6-pin standard SOT-23 (DBV) package. The device operates over wide temperature range of –40°C to 140°C.
