Description

The bq2400x series ICs are advanced Li-Ion linear charge management devices for highly integrated and space-limited applications. They combine high-accuracy current and voltage regulation; FET pass-transistor and reverse-blocking Schottky; battery conditioning, temperature, or input-power monitoring; charge termination; charge-status indication; and charge timer in a small package.

The bq24007 and bq24008 provide the timer-enable function, allowing the host to disable the charge timer when charge current is shared with a load or when the battery is absent. This feature is ideal for applications such as cellular phones, PDAs, and internet appliances.

The bq2400x measures battery temperature using an external thermistor.
