NCV47822中文资料Dual High Side Switch with Adjustable Current Limit and Diagnostic Features数据手册ONSEMI规格书

描述 Description

The NCV47822 dual channel High Side Switch (HSS) with 250 mA per channel is designed for use in harsh automotive environments. The device has a high peak input voltage tolerance and reverse input voltage, reverse bias, overcurrent and overtemperature protections. The integrated current sense feature (adjustable by resistor connected to CSO pin for each channel) provides diagnosis and system protection functionality. The CSO pin output current creates voltage drop across CSO resistor which is proportional to output current of each channel. Extended diagnostic features in OFF state are also available and controlled by dedicated input and output pins.
