Voltage Monitors/Sequencer Circuits with
Reverse-Sequencing Capability
General Description
The MAX16050 monitors up to 5 voltages and
sequences up to 4 voltages, while the MAX16051 moni-
tors up to 6 voltages and sequences up to 5 voltages.
These devices provide an adjustable delay as each sup-
ply is turned on and they monitor each power-supply
voltage. When all of the voltages reach their final values
and the reset delay timer expires, a power-on-reset
(POR) output deasserts allowing the microcontroller (μC)
to operate. If any voltage falls below its threshold, the
reset output asserts and all voltage supplies are turned
off. The MAX16050/MAX16051 can be daisy-chained to
control a higher number of voltages in a system.
During a power-down event, the MAX16050/MAX16051
can reverse sequence the outputs. In this situation, each
voltage is turned off sequentially until it reaches a 250mV
level, at which point, the next supply is turned off. The
MAX16050/MAX16051 also provide internal pulldown cir-
cuitry that turns on during power-down, to help dis-
charge large output capacitors.
The MAX16050/MAX16051 feature a charge-pump sup-
ply output that can be used as a pullup voltage for dri-
ving external n-channel MOSFETs and an overvoltage
output that indicates when any of the monitored voltages
exceeds its overvoltage threshold. The MAX16050 also
