The Diodes advantage

The APX810 and APX8123156 provide a simple cost effective solution for

µP/µC power supply supervisory applications

Circuit functions

µP supervisor and reset generator

µC supervisor and reset generator

Precision µP supervisor to monitor 2.5V, 3.0V, 3.3V and 5V power

supplies

Improves circuit reliability at low cost.

Wide range of thresholds to meet the needs of 2.5V, 3.0V, 3.3V

and 5V power supplies

The right threshold can be chosen to meet the needs of the system

Small footprint SOT143 green package

Small PCB area and halogen free

Manual reset (MR) input

Hardwire reset function to create manual reset or simple way of

coupling multiple supervisors together

No external components required

Reduces PCB area and cost.

Tiny microprocessor supervisors with

manual reset

Description

The APX811 and APX812 are

diodes latest addition to its

microprocessor supervisor

family.

These industry standard

devices provide power supply

monitoring for 2.5V, 3.0V, 3.3V

and 5V systems; ensuring that

µP/µC start up and recover

from power supply glitches into

a known state.

The APX811 has an active low

push-pull reset output while the

APX812 has an active high

push-pull reset output.

They are pin compatible to the

MAX811/MAX812 devices in

the tiny SOT143 package.

They are similar in function to

the APX809/APX810 and have

the added benefit of a manual

reset.

Both are available in green

mold compound as standard.
