Datasheet Summary
SGM836 Microprocessor Supervisory Circuit with Programmable Delay Time
GENERAL DESCRIPTION
The SGM836 family can monitor system voltages from 0.4V to 5V. When the detection voltage falls below the preset threshold (VITL) or the manual reset (nMR) pin is driven low, the open-drain nRESET output is asserted. After the detection voltage and nMR voltage return higher than their respective thresholds, the nRESET output remains low within the user-adjustable delay time.
The SGM836 uses a precision reference to achieve 1% threshold accuracy. The fixed reset timeout period can be set to 20ms by leaving the CT pin open and can be set to 300ms by connecting the CT pin to VDD through a resistor. The...
