MIC826
Overview
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.
- Precision 1.8V to 5V power supply monitor ±0.5% threshold accuracy at TA = +25°C ±1.5% threshold accuracy from TA = -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 50% smaller version of MAX823/MAX824/MAX825/ADM823/ADM824/ADM825
- 8x lower watchdog input current than competition Applica
