Product details

Description

plastic small outline package; 8 leads; body width 3.9 mm GENERAL DESCRIPTION SAA1504T The SAA1504T is manufactured in a BCD Power Logic 70 process and is intended to be used as a protection circuit for single cell Li-ion battery packs.The current and voltage ratings are especially designed for use in battery packs for portable telephones such as GSM.The circuit continuously monitors the battery voltage, current and junction temperature and will disconnect the battery in case of an overload

Features

Zero voltage start-up.
Discharge and charge overcurrent protection.
Automatic release of current protection at removal of charger or load.
Low current consumption in normal operating mode.
Very low current consumption when battery voltage is lower than 2.3 V.
Accurate voltage detection levels.
Continuous monitoring of battery voltage and charge or discharge current.
External power FETs are driven with an elevated supply vol.
