SGM836-1.8Q - Microprocessor Supervisory

General Description

The SGM836xQ 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.

Key Features

  • AEC-Q100 Qualified for Automotive.

GENERAL DESCRIPTION The SGM836xQ 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 SGM836xQ uses a precision reference to achieve 2.2% threshold accuracy under the temperature range of -40℃ to +125℃. The fixed reset timeout period can be set to 20ms by leaving the CT pin open and can be set to 300ms by conn
