Voltage Monitors/Sequencer Circuits with

Reverse-Sequencing Capability

/MAX6051

General Description

Features

♦ Monitor Up to 6 Voltages/Sequence Up to 5

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.

Voltages

♦ Pin-Selectable Sequencing Order (MAX16050 Only)

♦ Reverse-Sequencing Capability on Shutdown

♦ Overvoltage Monitoring with Independent Output

♦

1ꢀ5ꢁ ꢂhreshold Accuracy

♦ 2ꢀ7V to 13ꢀ2V Operating Voltage Range

♦ Charge Pump to Fully Enhance External

n-Channel FEꢂs

♦ Capacitor-Adjustable Sequencing Delay

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.

♦ Fixed or Capacitor-Adjustable Reset ꢂimeout

♦ Internal 85mA Pulldowns for Discharging

Capacitive Loads Quickly

♦ Daisy-Chaining Capability to Communicate

Across Multiple Devices

♦ Small 4mm x 4mm, 28-Pin ꢂQFN Package

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

provides three sequence control inputs for changing the

sequence order, while the MAX16051 has a fixed

sequence order.
