Today, we will introduce the SL4427 Dual Low Side Driver.

Description

The SL4427 is a dual 4A high-speed low-side gate driver that efficiently and safely drives MOSFETs as well as IGBTs.Available in SOP-8 packages with or without thermal pads, low propagation delays and mismatches allow MOSFETs to switch in the hundreds of kHz.This chip is very suitable for the synchronous rectification drive of server and communication power supplies, in which the dead time of the synchronous MOSFET directly affects the efficiency of the converter. The driver can increase the output drive current by paralleling two channels. When only one enable pin is enabled high (the other enable pin is floating), the outputs of both channels are driven by a phase-one logic signal This feature can greatly reduce the mismatch between the two channels and make it suitable for driving parallel switches.The driver's input thresholds are based on TTL levels up to 20V tolerance.
