Positive Supply Input Voltage. Bypass V
Gate-Driver Output. Connect GATE1 to the gate of an external p-channel FET pass switch to pro-
vide low drain-to-source voltage drop, reverse voltage protection, and back-charge prevention.
Differential Voltage Sense Input (Input Side of IC). Used with SENSE OUT to provide back-charge
prevention when the SENSE IN voltage falls below the SENSE OUT voltage by 25mV.
Active-Low Shutdown/Wake Input. Drive SHDN high to turn on the voltage detectors. GATE2 is
shorted to V
Connect SHDN to V
Open-Drain Overvoltage Indicator Output. Connect a pullup resistor from OV to a positive supply
such as V
Ground
Controller Overvoltage Threshold Programming Input. Connect SET to the center of an external
resistive divider network between TERM and GND to adjust the desired overvoltage switch-off or
limiter threshold.
Voltage-Divider Termination Output. TERM is internally connected to SENSE OUT in the MAX16915
and to V
zero in the resistor-divider connected to TERM.
Differential Voltage Sense Input (Output Side Of IC). Used with SENSE IN to provide back-charge
prevention when the SENSE IN voltage falls below the SENSE OUT voltage by 25mV.
Gate-Driver Output. Connect GATE2 to the gate of an external p-channel FET pass switch. GATE2
is driven low during normal operation and quickly regulated or shorted to V
age condition. GATE2 is shorted to V
