MAX822 - 4-Pin uP Voltage Monitors

Download the MAX822 datasheet PDF. This datasheet also covers the MAX821 variant, as both devices belong to the same 4-pin up voltage monitors family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX821/MAX822 microprocessor (µP) supervisory circuits monitor power supplies in µP and digital systems.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered or 3V-powered circuits.

19-1122; Rev 1; 12/99 MAX821/MAX822 4-Pin µP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay General Description The MAX821/MAX822 microprocessor (µP) supervisory circuits monitor power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered or 3V-powered circuits. The MAX821/MAX822 also provide a power-on reset timeout delay that is pin selectable to 1ms (max), 20ms (min), or 100ms (min). These devices perform a single function: they assert a reset signal whenever the VCC supply voltage falls below a preset threshold, and they keep reset asserted for the pin-selected reset timeout delay after VCC has risen above the reset threshold.
