Product details

Supervisor IC for 5 V rails — 140 ms timeout, dual reset outputs

The Maxim Integrated MAX814LESA is a simple reset/power-on reset supervisor IC monitoring a single 4.7 V threshold rail. It asserts both active-high and active-low push-pull reset outputs for a minimum of 140 ms after the supply rises above the threshold, holding downstream logic in reset until the rail stabilizes.

140 ms minimum reset timeout — what it buys you

Dual reset outputs — one part, two polarities

Active-high and active-low push-pull outputs on the same die mean this single supervisor can drive both an MCU reset pin (active-low) and a peripheral enable (active-high) without an external inverter. Both outputs are asserted during the timeout and de-asserted together when the timeout expires. No open-drain pull-up resistors needed — the push-pull stage drives rail-to-rail.

The 8-SOIC package keeps board area small while offering enough pin pitch for manual rework or inspection.

The part is RoHS non-compliant, which may matter for EU RoHS-exempt applications or legacy BOMs where lead-bearing solder is still accepted.

Frequently asked questions

What is the exact reset timeout of MAX814LESA?

The reset timeout is 140 ms minimum. This is the guaranteed hold time the reset outputs stay asserted after the monitored voltage rises above the 4.7 V threshold.

Can MAX814LESA be used as a direct replacement for MAX813L?

The MAX813L is a different supervisor with a 4.65 V threshold and a 200 ms timeout. The MAX814LESA uses a 4.7 V threshold and a 140 ms timeout. Verify your system's threshold tolerance and reset hold time requirements before substituting — the pinout may differ, and the timing change could affect power-up sequencing.

Is MAX814LESA compatible with 3.3 V systems?

No — the threshold voltage is 4.7 V, designed for monitoring 5 V rails. For 3.3 V systems, select a supervisor with a threshold near 3.0 V or 3.1 V.
