Overview
NCV47822 Dual High Side Switch with Adjustable Current Limit and Diagnostic Features 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.
Features • Output Current per Channel: up to 250 mA • Two Independent Enable Inputs (3.
3 V Logic Compatible) • Adjustable Current Limits: up to 350 mA • Protection Features: ♦ Current Limitation ♦ Thermal Shutdown ♦ Reverse Input Voltage and Reverse Bias Voltage • Diagnostic Features: ♦ Short To Battery (STB) and Open Load (OL) in OFF State ♦ Internal Components for OFF State Diagnostics ♦ Open Collector Flag Output ♦ Two Output Voltage Monitoring Outputs (Analog) • AEC−Q100 Grade 1 Qualified and PPAP Capable • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Typical Applications • Audio and Infotainment System • Active Safety System Cin 1 μF Vin EN1 Diagnostic Enable Input DE Diagnostic Channel Select Input CS Vout1 Vout_FB1 CSO1 CCSO1 NCV47822 (Dual HSS) 1 μF EF Vout2 Proportional Voltage to V out1* RCSO1 Cout1 1 μF Error Flag Output (Open Collector) EN2 GND Vout_FB2 CSO2 CCSO2 1 μF Proportional Voltage to V out2* RCSO2 Cout2 1 μF * Vout_FB1 and Vout_FB2 are sensed Vout1 and Vout2 output voltages, respectively, via internal resistor dividers Figure 1.
