Low-Voltage, High-Accuracy, Quad Window

Voltage Detectors in Thin QFN

General Description

Features

♦ Monitor Four Undervoltage/Overvoltage Conditions

♦ 1.5% Accuracy Over Temperature

The MAX16008/MAX16009 are adjustable quad window

voltage detectors in a small thin QFN package. These

devices are designed to provide a higher level of sys-

tem reliability by monitoring multiple supply voltages

and providing a fault signal when any of the voltages

exceed their overvoltage thresholds or fall below their

undervoltage thresholds.

♦ User-Adjustable Thresholds (Down to 0.4V)

♦ Open-Drain Outputs with Internal Pullups Reduce

the Number of External Components

♦ Manual Reset Input (MAX16009)

These devices offer user-adjustable thresholds that

allow voltages to be monitored down to 0.4V. These

devices allow the upper and lower trip thresholds of

each window detector to be set externally with the use

of three external resistors.

♦ Margin Enable Input

♦ Fixed or Adjustable RESET Timeout (MAX16009)

♦ Guaranteed Correct Output Logic State Down to

= 1V

Each monitored threshold has an independent open-

drain output for signaling a fault condition. The outputs

can be wire OR’ed together to provide a single fault

output. The open-drain outputs are internally pulled up

with a 30µA current, but can be externally driven to

other voltage levels for interfacing to other logic levels.

♦ Fully Specified from -40°C to +125°C

♦ Small, 4mm x 4mm Thin QFN Package

PART

Both devices feature a margin input to disable the out-

puts during margin testing or any other time after

power-up operations. The MAX16009 offers a reset out-

put that deasserts after a reset timeout period after all

voltages are within their threshold specifications. The

reset timeout is internally set to 140ms (min), but can

be externally adjusted to other reset timeouts using an

external capacitor. In addition, the MAX16009 offers a

manual reset input.
