PIN DESCRIPTION Pin # Name Description 16L SOIC
1,2,3,4 IP+ Input of Primary Current Path for Sensing, Fused internally 5,6,7,8 IP- Output of Primary Current Path for Sensing, Fused internally 9 FAULTB Overcurrent FAULTB open drain output. Active low. 10 VCC System Power Supply 11 GND Recommended to connect to ground 12 Vout Analog Output Signal linearly proportional to Primary Path Current 13 Vcap Connect 10nF capacitance to ground Used during initial factory calibration. This pin should be 14 GND connected to ground or left floating during normal operation. Pin 1 15 GND Connect to ground Input pin. Voltage on this pin defines the overcurrent detection 16-pin SOIC 16 VOC OCD threshold level. Briefly driving this pin to VCC resets and re- arms OCD circuit.
