General Description

The MIC826 is a low-current, ultra-small, voltage

supervisor with manual reset input, watchdog timer,

and active-high and active-low push-pull outputs. The

reset outputs are asserted and held when the supply

voltage falls below the factory-programmed threshold

voltage, when the /MR pin is pulled low, or if the

watchdog times out. Reset is asserted for the reset

timeout delay after the supply voltage increases above

the rising threshold voltage or when manual reset input

is asserted high.

The MIC826 features an integrated pull-up resistor on

the /MR. An active-low push-pull reset output (/RESET)

and an active-high reset output (RESET) provide

flexibility

when

interfacing

with

various

microcontrollers, PMICs, or load switches. The

watchdog input can be left unconnected for

applications that do not require watchdog monitoring.

The MIC826 consumes a quiescent current of only

3.8 µA and is offered in a tiny, space-saving, 6-lead

1.6 mm x 1.6 mm UDFN package. It is rated for the

–40°C to +125°C temperature range.
