MIC1232 - 5V Voltage Supervisor

Description

The MIC1232 is a low-current microprocessor supervisor for monitoring 5V systems.

Features

  • logic selectable (TOL) reset thresholds of 5% or 10% of 5V; a pushbutton reset input (/PBRST); a watchdog timer with three-state selectable (TD) timeout periods of 150ms, 600ms, or 1.2s; a fixed reset timeout period of 250ms (min); and active-low open-drain reset (/RST) and activehigh push-pull reset (RST) outputs. The /RST output maintains a valid reset condition for VCC as low as 1.4V. The MIC1232 asserts a reset condition if the supply voltage drops below the reset threshold, the pushbutton r.
