JUYI Tech 450mA / 850mA Mosfet High Side Switch , 3.3V Logic Compatible Bldc Mosfet Driver
JY21L High and Low side driver, high voltage, high speed power MOSFET and IGBT driver based on P-SUB P-EPI process.
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
● Fully operational to +150V
● 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
