Texas Instruments bq24004
The bq2400x series ICs are advanced Li-Ion linear charge management devices for highly integrated and space-limited applications. They combine highaccuracy current and voltage regulation; FET passtransistor and reverse-blocking Schottky; battery conditioning, temperature, or input-power monitoring; charge termination; charge-status indication; and charge timer in a small package. The bq2400x measures battery temperature using an external thermistor.| Part No. | bq24004 |
