19-5570; Rev 1; 8/11
36V-Capable Overvoltage Protector with
Regulated Output Voltage
General Description
The MAX14562 protects valuable consumer circuits
against voltage faults of up to +36V. This robust protec-
tion is implemented in a three-step scheme for a superior
result. If the input is below the preset regulated output-
voltage (VPROV) threshold, the output tracks the input
minus the voltage drop (RON x ILOAD) across the pass
FET. If the input exceeds VPROV, the output is regulated
to VPROV. If the input rises further and exceeds the over-
voltage lockout cutoff threshold (VOVLO), the output is
disconnected from the input.
A low resistance 160mI (typ) FET is integrated in the
MAX14562, effectively reducing the component count
and application footprint. The MAX14562 also features
thermal shutdown protection against a short-circuit
event.
The MAX14562 is specified over the extended -40NC to
+85NC temperature range and is available in 8-pin TDFN
(2mm x 2mm) package.
