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.
