PT7M1818/1813

Supervisory Circuit

Features



Highly accurate:

1.5%

(25°

Accurate power monitoring: 2.5V, 2.9V, 3.0V

(PT7M1818), and 4.1, 4.3, 4.6V (PT7M1813)

Operating voltage range: 1.0V ~ 5.5V

Operating temperature range: -40° to + 85°

Detect voltage temperature characteristics:

2.5% 

TYP

Efficient open-drain output with internal 5k pull-up

resistor

Maintains reset for 200ms after V

returns to an in-

tolerance condition

Description

The series are designed to monitor power supplies in µ

and digital systems. It provides excellent circuit

reliability and low cost by eliminating external

components and adjustments.

This device performs a single function: it asserts a reset

signal whenever the V

supply voltage falls below a

preset threshold. Reset remains asserted for 200ms after

has risen above the reset threshold.

PT7M1818/1813 are bidirectional output, allowing it to

be directly connected to µ with bidirectional reset

inputs.
