Description
The VNB49N04, VNV49N04 are monolithic devices
designed in STMicroelectronics™ VIPower™ M0
technology, intended for replacement of standard
Power MOSFETs from DC up to 50 KHz
applications.
Built-in thermal shutdown, linear current limitation
and overvoltage clamp protect the chip in harsh
environments.
Fault feedback can be detected by monitoring the
voltage at the input pin.
