Microprocessor Supervisory Circuit with Programmable Delay Time

The SGM829 family can monitor system voltages from 1.8V to 5V. When the VDD voltage falls below a preset threshold (VIT) or the manual reset (nMR) pin is driven low, the open-drain nRESET output is asserted. After the VDD voltage and nMR voltage return above their respective thresholds, the nRESET output remains low within the user-adjustable delay time.

The SGM829 uses a precision reference to achieve 1% threshold accuracy. The fixed reset timeout period can be set to 0.29ms by leaving the SRT pin open. The programmable reset timeout period can be set from 1.25ms to 10s through an external capacitor connected to the SRT pin. Low quiescent current makes the SGM829 very suitable for battery-powered applications.

The SGM829 is available in a Green SOT-23-5 package.
