MIC2790L-04VD6-T5, Supervisory Circuits Supervisor with High-Accuracy, Ultra-Fast Propagation Delay and Capacitor-Progra

MIC2790/1/3 Power Management ICs
Microchip MIC2790/1/3 Power Management IC is ideal for monitoring 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), 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 Microchip 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.
