SENSE:
Input voltage from current sense resistor. When
there is greater than 50mV across this pin with respect to
VCC, a fault is sensed and C
T
begins to charge.
VCC:
Input voltage to the IC. Typical voltages are 4.5V to
35V. The minimum input voltage required for operation is
4.5V.
VOUTS:
Source connection of external N-channel MOS-
FET and sensed output voltage of load.
VPUMP:
Charge pump output voltage. A capacitor
should be tied between this pin and VOUTS with a typi-
cal value being 0.01
