Texas Instruments bq24201 Datasheet
The bq24201 is a single‑chip charge management IC designed for low‑dropout charging of single‑cell Li‑ion or Li‑Pol batteries. It integrates a PowerFET, high‑accuracy voltage regulation, temperature monitoring, charge status output, and safety timers in an 8‑pin MSOP package.
Key features include a 500 mA integrated PowerFET, 0.5 % voltage regulation accuracy, battery insertion detection, pre‑charge conditioning, and a STAT pin that indicates charge‑in‑progress, charge‑complete, and fault conditions. The device operates from a current‑limited wall supply and provides optional temperature monitoring via the TS pin.

Questions answered in these manuals
What is the maximum charge current the bq24201 can deliver?
The device includes an integrated PowerFET rated for a maximum charge current of 500 mA.
How does the bq24201 monitor battery temperature?
Temperature is sensed on the TS pin using an external thermistor; the voltage on TS is compared to internal thresholds to enable or suspend charging.
How does the bq24200 series monitor battery temperature?
Temperature is monitored via an external thermistor connected to the TS pin, which the IC compares against internal thresholds.
