PCS811/PCS812

5-Pin µP Voltage Supervisor with Manual Reset

FEATURES

DESCRIPTION

PCS811/PCS812 are low-power microprocessor (µP)

supervisory circuits used to monitor power supplies in µP

and digital systems. They provide applications with

benefits of circuit reliability and low cost by eliminating

•

Ultra Low Supply Current 1µA(typ.)

Guaranteed Reset Valid to VCC=0.9V

Available in two Output Types: Push-Pull

Active Low (PCS811), Push-Pull Active High

(PCS812)

external components. PCS811/PCS812 also offer

manual reset input.

•

140ms Min. Power-On Reset Pulse Width

Internally Fixed Threshold 2.3V, 2.6V, 2.7V,

2.9V, 3.1V, 4.0V, 4.4V, and 4.6V

Tight Voltage Threshold Tolerance: 1.5%

Low profile Package: SOT-23-5

These devices perform as valid singles in applications with

VCC ranging from 6.0V down to 0.9V. The reset signal

lasts for a minimum period of 140ms whenever VCC

supply voltage falls below preset threshold. Both PCS811

and PCS812 were designed with a reset comparator to

help identify invalid signals, which last less than 140ms.

The only difference between them is that they have an

active-low RESET output and active-high RESET output,

respectively.
