Micrel Inc. announced the MIC826 ±0.5 percent accuracy voltage supervisor, with manual reset input, watchdog timer and dual outputs in space saving 1.6mm x 1.6mm thin DFN package.
According to Micrel, the device reduces solution size up to 70% compared with competing products, and improves the accuracy of the power supply monitor by 1 to 2 percent vs. the competition over the -40ºC to +125ºC temperature range. The device is aimed at portable applications, as well as industrial and automotive applications. The MIC826 offers eight reset threshold options and is intended to monitor 1.8V to 5V power supplies. The device features a ±0.5 percent voltage threshold accuracy at room temperature and ±1.5 percent voltage threshold accuracy over the -40ºC to +125ºC temperature range.
The solution consumes a low 3.8µA of supply current for power supplies; lower than 3.6V and 4.8µA for solutions operating from a 5V power supply. The IC also features an industry standard reset timeout period of 140ms (min) and a watchdog time output period of 1.6s, as well as dual, active-high push-pull, and active-low push-pull reset outputs in a space saving 1.6mm x 1.6mm x 0.55mm thin DFN package.
The MIC826 is currently available in volume quantities, with 1,000-quantity pricing starting at $0.32.
