Microchip Voltage Supervisor 4.63V max. 3-Pin SOT-23, MIC2790N-04VD6-TR

The Microchip 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.
