Primary sampled current conduction path input; power input pins: connected to VCC.  
EN  
Enable pin. The falling edge on the EN pin clears an overpower, overcurrent, or short circuit fault.  
Analog output. Output voltage on this pin is proportional to the current flowing from the IP+ pins to the IP– pins.  
No connect. Connection to ground is recommended.

VIOUT  
NC  
9
Terminal for CG capacitor. May be used to adjust the turn-on time and soft start control of an external MOSFET,  
S1. Voltage on this pin limits inrush current through MOSFET S1. Set via external capacitance, CG, connected  
between this pin and GND. This capacitor is charged by an internal 20 μA current source.

CG  
Terminal for external capacitor, COCD, Used to adjust delay for overcurrent shutdown, set via the external  
capacitor, COCD, connected between this pin and GND.

OCDLY  
OPDLY  
Terminal for external capacitor, COPD, Used to adjust delay for overpower shutdown, set via the external capacitor,  
COPD, connected between this pin and GND.  
Active low; output signal for device short circuit and overpower faults. Connect a pull-up resistor between this pin  
and the 3.3 V rail.

Active low; output signal indicating load voltage has risen to the proper level.  
Input of positive feedback on output voltage. Used to determine overpower fault threshold by difference between  
FB+ and GND pins.

PGOOD  
GND  
Active high; output signal indicating load voltage has risen to the proper level.  
Terminal for ground connection.  
Terminal for external MOSFET, S1. Provides output voltage to drive S1. Current through S1 is controlled at start-  
up by external capacitance connected between the CG pin and GND.
