SLVSC82B August 2013 – October 2015 UCC27531-Q1
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.
