Micrel MIC826 voltage supervisor

Micrel MIC826 Voltage Supervisor

Micrel MIC826 delivers 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 3.8μA 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.
