ZHCSWR1H December 2009 – July 2024 DRV8412
PRODUCTION DATA
The DRV841x2 contains advanced protection circuitry carefully designed to facilitate system integration and ease of use, as well as to safeguard the device from permanent failure due to a wide range of fault conditions such as short circuits, overcurrent, overtemperature, and undervoltage. The DRV841x2 responds to a fault by immediately setting the half bridge outputs in a high-impedance (Hi-Z) state and asserting the FAULT pin low. In situations other than overcurrent or overtemperature, the device automatically recovers when the fault condition has been removed or the gate supply voltage has increased. For highest possible reliability, reset the device externally no sooner than 1 second after the shutdown when recovering from an overcurrent shut down (OCSD) or OTSD fault.
