AIC811/AIC812

Reset Circuits with Manual Reset Input

ꢀFEATURES

ꢀDESCRIPTION

ꢁ Ultra Low Supply Current 1µA(typ.)

ꢁ Guaranteed Reset Valid to Vcc=0.9V

AIC811/AIC812 are low-power microprocessor (µP)

supervisory circuits used to monitor power supplies in

ꢁ Available in two Output Types: Push-Pull Active

Low (AIC811), Push-Pull Active High (AIC812)

ꢁ 140ms Min. Power-On Reset Pulse Width

ꢁ Internally Fixed Threshold 2.3V, 2.6V, 2.9V,

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

µP and digital systems. They provide applications with

benefits of circuit reliability and low cost by eliminating

external components. AIC811/AIC812 also offer a

manual reset input.

ꢁ 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

AIC811 and AIC812 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.

Low supply current (1µA) makes AIC811/AIC812 ideal

for portable equipment. The devices are available in

SOT-23-5 package.
