JY21L

High and Low side driver

General Description

The product is a high voltage, high speed power MOSFET and IGBT driver based on P-SUB P-EPI process. The floating channel driver can be used to drive two N-channel power MOSFET or IGBT independently which operates up to 150V. Logic inputs are compatible with standard CMOS or LSTTL output, down to 3.3V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver cross conduction. Propagation delays are matched to simplify use in high frequency applications. 

Features

● 3.3V logic compatible

● Floating channel designed for bootstrap operation
● Gate drive supply range from 5.5V to 20V
● Output Source/Sink current capability 450mA/850mA
● Independent Logic input to accommodate all topologies
● -5V negative Vs ability
● Matched propagation delay for both channels

Applications

● Power MOSFET or IGBT driver
● Small and medium-power motor driver
