TERMINAL FUNCTIONS
TERMINAL
I/O DESCRIPTION
NAME NO.
Connect a resistor to ground to program the turn-off threshold. Leaving RSET open results in a slightly
RSET 1 I
positive V
(A-C)
turn-off threshold.
EN 2 I Pull EN above 1.3 V to permit normal ORing operation. A low on EN holds GATE low.
RSVD 3 PWR This pin must be connected to GND.
GND 4 PWR Device ground.
GATE 5 O Connect to the gate of the external MOSFET. Controls the MOSFET to emulate a low forward-voltage diode.
Voltage sense input that connects to the simulated diode cathode, and also serves as the bias supply for the
C 6 I
gate drive charge pump and internal controls. Connect to the MOSFET drain in the typical configuration.
Voltage sense input that connects to the simulated diode anode, and also serves as the reference for the
A 7 I
charge-pump bias supply on BYP. Connect to the MOSFET source in the typical configuration.
BYP 8 I/O Connect a capacitor from BYP to A to filter the gate drive supply voltage.
