MIC1832 - 3.3V Voltage Supervisor

General Description

The MIC1832 is a low-current microprocessor supervisor for monitoring 3.3V and 3V systems.

Key Features

  • logic-selectable (TOL) reset thresholds of 10% or 20% of 3.3V; a pushbutton reset input; 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 MIC1832 asserts a reset condition if the supply voltage drops below the reset threshold, the pushbutton reset i.
