Single Channel 20-mΩ Smart High Side Driver with Advanced Protections and Diagnostics
SC77120BQ
The SC77120BQ is a fully-protected single channel smart
high side driver qualified in automotive grade. Full
diagnostics and high accuracy current sense of each
channel enable intelligent control of the load even in harsh
conditions. It integrates single channel 20mΩ MOSFETs in
a compact package size with advanced protections of load
current limitation, dynamic thermal swing shutdown,
absolute thermal shutdown. Besides, it features chip
junction temperature and supply voltage sense output to
monitor the driver status more precisely. A multiplexed pin
delivers these analog signals and the digital signal of fault
indication for over temperature in on-state and open load in
off-state.
