MIC826

Voltage Supervisor with Watchdog Timer,

Manual Reset, and Dual Outputs

In 1.6mm x 1.6mm TDFN

General Description

Features

The MIC826 is

low-current, ultra-small, voltage

• Precision 1.8V to 5V power supply monitor

• ±0.5% threshold accuracy at T_A= +25°C

• ±1.5% threshold accuracy from T_A= –40°C to +125°C

• 3.8µA supply current (MIC826S/R/T/W/Y/Z)

• 4.8µA supply current (MIC826L/M)

• Manual reset input

• 140ms (min.) reset timeout period

• 1.6s (typ.) watchdog timeout period

• Float watchdog timer input to disable watchdog timer

• Active-high and active-low push-pull outputs

• Guaranteed reset output valid to VCC = 1V

• −40°C to +125°C junction temperature range

• 6-pin 1.6mm x 1.6mm x 0.5mm Thin DFN package

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.

• 50% smaller version of

The MIC826 consumes a quiescent current of only 3.8µA

and is offered in a tiny, space-saving, 6-pin 1.6mm x

1.6mm Thin DFN package. It is rated for the –40°C to

+125°C temperature range.

• 8x lower watchdog input current than competition
