MIC826
Voltage Supervisor with Watchdog Timer,
Manual Reset, and Dual Outputs
In 1.6mm x 1.6mm TDFN General Description Features 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 3.8ВµA
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
+125В°C temperature range. …
