MAX16914/MAX16915
Ideal Diode, Reverse-Battery, and Overvoltage Protection
Switch/Limiter Controllers with External MOSFETs
General Description
The MAX16914/MAX16915 low-quiescent-current over-
voltage and reverse-battery protection controllers are
designed for automotive and industrial systems that
must tolerate high-voltage transient and fault conditions.
These conditions include load dumps, voltage dips, and
reversed input voltages. The controllers monitor the input
voltage on the supply line and control two external pFETs
to isolate the load from the fault condition. The external
pFETs are turned on when the input supply exceeds
4.5V and stay on up to the programmed overvoltage
threshold. During high-voltage fault conditions, the con-
trollers regulate the output voltage to the set upper
threshold voltage (MAX16915), or switch to high resis-
tance (MAX16914) for the duration of the overvoltage
transient to prevent damage to the downstream circuitry.
The overvoltage event is indicated through an active-low,
open-drain output, OV .
The reverse-battery pFET behaves as an ideal diode,
