Overview
a Microprocessors Supervisory Circuit in 4-Lead SOT-143 ADM811/ADM812 FUNCTIONAL BLOCK DIAGRAM ADM811/ADM812 VCC VREF RESET GENERATOR RESET/RESET FEATURES Superior Upgrade for MAX811/MAX812 Specified Over Temperature Low Power Consumption (5 ␮A Typ) Precision Voltage Monitor: +3 V, +3.
3 V, +5 V Options Reset Assertion Down to 1 V VCC 140 ms Min Power-On Reset Logic Low RESET Output (ADM811) Logic High RESET Output (ADM812) Built-In Manual Reset APPLICATIONS Microprocessor Systems Controllers Intelligent Instruments Automotive Systems Safety Systems Portable Instruments MR DEBOUNCE GND GENERAL DESCRIPTION The ADM811/ADM812 are reliable voltage monitoring devices suitable for use in most voltage monitoring applications.
The ADM811/ADM812 are designed to monitor five different voltages, each allowing for a 5% or 10% degradation of standard PSU voltages before a reset occurs.
These voltages have been selected for the effective monitoring of +3 V, +3.
3 V and +5 V supply voltage level...
