GENERAL DESCRIPTION

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.

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 voltage, reducing the on-resistance

? Able to accommodate 20 V charge voltage

? Read out of charge (disable) status

? Small package (SO8)

? Low external components count

? Temperature protection

? Charger reverse connection protection.
