High Accuracy, Ultra-Small, Voltage Supervisor

High Accuracy, Ultra-Small, Voltage Supervisor

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. The device is aimed at portable applications which require small size, high integration, and low current consumption.

The MIC826 features a precision voltage monitor, manual reset, watchdog timer and dual outputs in a small package. This provides the designer with high integration while reducing solution size up to 70 percent compared to competing solutions. The device also improves the accuracy of the power supply monitor by 1 to 2 percent over the -40°C to +125°C temperature range.

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 -40°C to +125°C 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.
