Device Overview

Summary

The MIC2790/1/3 is ideal for monitoring highly-accurate core voltages that require rapid response in the event of a fault condition. The voltage supervisor IC features a manual reset input, enable input (MIC2793 only), a capacitor-programmable reset timeout delay and both an active-low and active-high reset output. The MIC2790/1/3 monitors system voltages that are in the range of 0.4V to 5.5V, with a typical sense accuracy of 0.5% at +25°C and ±1.0% across −40°C to +125°C. The IC asserts a reset output when the sense voltage drops below the threshold or when the manual reset is pulled to a logic low. The active-low reset stays low for the duration of the reset timeout delay once the sense voltage returns to normal and the manual reset transitions to a logic high state. The reset timeout delay period is programmable from 1ms to 10s with an external capacitor. The MIC2790/1/3 operates from a low supply voltage of 1.5V to 5.5V, and is rated to operate over the temperature range of −40°C to +125°C. The MIC2790 is available in a 6-pin TSOT-23 package or a 6-pin 2mm × 2mm × 0.55mm DFN package. The MIC2791 is available in a tiny 6-pin 1.6mm × 1.6mm × 0.55mm DFN package. The MIC2793 is available in a 8-pin 2mm × 2mm × 0.55mm DFN package.
