Pin Functions (DE12/Package/MS Package)

resistor is placed in the power path between SENSEP and

SENSEN pins to sense the output current. The electronic

circuit breaker trips if the voltage across the sense resistor

exceeds 25mV for more than a fault filter delay.

SENSEP (Pin 10/Pin 9): Circuit Breaker Positive Sense

Input. Connect this pin to the sense resistor terminal

wired to the positive supply input for the external output

load. This positive supply range extends from 0V to 6V.

VCC (Pin 11/Pin 10): Bias Supply Input. Operates from 2.3V

to 6V. An internal undervoltage lockout circuit disables

the device until the input supply voltage at VCC exceeds

2.12V typically.

FAULT (Pin 12/Not Available): Fault Input and Output. As

an input, driving this pin low (<1.253V) will latch-off the

device to fault mode. As an output, it is either pulled high

by an internal 5µA pull-up or an external pull-up resistor

to positive supply under normal operating condition. It

pulls low when the circuit breaker is tripped due to an

overcurrent fault.

Exposed Pad (Pin 13/Not Available): Exposed pad may

be left open or connected to device ground.
