Description

The SL27511A is a 4A peak source and 8A peak sink drive single-channel, high-speed, low-side gate driver, capable of effectively and safely driving MOSFETs, IGBTs and emerging WBG power switches. Low propagation delay and compact SOT- 23 package enable fast switching at hundreds of kHz. It is very suitable for server and telecom power supply’s synchronous rectification driving, where synchronous MOSFET’s dead time accuracy directly impacts converter’s efficiency. Wide VDD operating range from 4.5V to 20V enables effective driving with MOSFET or GaN power switches. Integrated UVLO protection ensures output held at low under abnormal conditions.

The independent inputs range from -5V to 24V ensure robust operation with undershoot or overshoot induced by parasitic inductances. The input thresholds are compatible with TTL input.
