SAA1504T Description
plastic small outline package; 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.
SAA1504T Key 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 acmodate 20 V charge voltage
- Read out of charge (disable) status
