Preliminary Specification

Revision 1.5

January 31, 2007

General Description

Applications

•

Battery Packs and Chargers

Electronic System protection

Specifically design to reside in battery packs, the

device AQ265 is used to stop the charge or discharge

of a battery when the battery temperature is outside of

the safe temperature range.

The AQ265 is an accurate low-power solid-state

thermostat that provides shut down alarm at both cold

and hot temperatures. It features very low standby

current, which prolongs battery shelf life. The hot

temperature trip point is 40ºC and can be adjusted

with one external resistor from 40ºC to 90ºC. The cold

trip point is -20ºC and can be adjusted with one

external resistor from -20ºC to 15ºC. Thermal

hysteresis is internally programmed to guarantee

stability at the transition points.

Features

• 20µA off state current, prolongs battery shelf life

•

+/-3 degrees Celsius accuracy

Adjustable Hot and cold temperature trip points

• Internally programmed thermal hysteresis

• Excellent power supply noise rejection

•

Offered in very small SOT23-5 package.

RoHS Compliant

At temperatures between its hot and cold trip points,

the AQ265 lies quietly with open drain while drawing

ICC of only 20µA. When either the hot or cold

threshold temperature is reached the OUT pin will sink

>200µA providing a low power signal to disconnect the

battery from its load and/or charger.
