MAX16126/MAX16127
Load-Dump/Reverse-Voltage Protection Circuits
General Description
The MAX16126/MAX16127 load-dump/reverse-voltage
protection circuits protect power supplies from dam-
aging input voltage conditions, including overvoltage,
reverse-voltage, and high-voltage transient pulses. Using
a built-in charge pump, the devices control two exter-
nal back-to-back n-channel MOSFETs that turn off and
isolate downstream power supplies during damaging
input conditions, such as an automotive load-dump pulse
or a reverse-battery condition. Operation is guaranteed
down to 3V to ensure proper operation during automo-
tive cold-crank conditions. These devices feature a flag
output ( FLAG ) that asserts during fault conditions.
For reverse-voltage protection, external back-to-back
MOSFETs outperform the traditional reverse-battery
diode, minimizing the voltage drop and power dissipa-
tion during normal operation.
The MAX16126/MAX16127 use external resistors to
adjust the overvoltage and undervoltage comparator
thresholds for maximum flexibility.
The MAX16127 provides limiter-mode fault manage-
ment for overvoltage and thermal shutdown conditions;
whereas the MAX16126 provides switch-mode fault
management for overvoltage and thermal shutdown con-
ditions. In the limiter mode, the output voltage is limited
and FLAG is asserted low during a fault. In the switch
mode, the external MOSFETs are switched off and FLAG
is asserted low after a fault. The switch mode is available
in four options: latch mode, 1 autoretry mode, 3 autoretry
mode, and always autoretry mode.
The MAX16126/MAX16127 are available in 12-pin TQFN
