MIC2790N-04VMT T5

The MIC2790N-04VMT T5 is a Voltage Supervisor IC with active-low open-drain output, high-accuracy ultrafast propagation delay and capacitor-programmed reset delay. It is ideal for monitoring highly-accurate core voltages that require rapid response in the event of a fault condition. The MIC2790 monitors system voltages that are in the range of 0.4 to 5.5V, with a typical sense accuracy of 0.5% at +25°C and ±1.0% across -40 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.

• Ultrafast propagation delay (1µs typically)
• Programmable reset timeout delay (from 1ms to 10s)
• Manual reset input with an internal pull-up resistor
