Understanding IC1 Functionality
Thought for 1 min 8 sec
I found several charger ICs that fit your requirements for a Li-ion cell with integrated power-path management and status outputs:
Table
| Part Name | Part Uid | MPN | Package | Key Features | Datasheet |
|---|---|---|---|---|---|
| BQ21040DBV | 6dd9569f-3c53-4290-918a-413d824b3689 | BQ21040DBV | SOT-23-6 | 0.8 A linear charger, input up to 30 V, open-drain CHG/STAT outputs, thermal regulation, I²C status monitoring. | |
| MP2662GC-XXXX-P | f0b65ee2-deac-457e-a003-342030408b1c | MP2662GC-XXXX-P | WLCSP-9 | 500 mA switching charger, integrated power-path, seamless battery/system switchover, < 1 μA standby, programmable termination current, thermistor input. | |
| BQ24075RGTT (module) | bef207fe-d163-4ea0-b898-afdf21e53f84 | BQ24075 (module) | DFN-10 | Reference module using BQ24075RGTT, 1 A switch-mode charger, power-path management between VIN, BAT, SYS, dual status flags, battery thermistor, minimal external parts. |
Recommendation rationale:
- BQ21040DBV is compact (SOT-23-6) and provides up to 0.8 A charge current with standard status outputs—great if you can trade efficiency for simplicity.
- MP2662GC-XXXX-P offers a fully integrated switching approach (higher efficiency, smaller standby current) in a tiny WLCSP.
- BQ24075 module is ideal if you prefer a turnkey reference design with minimal layout risk and full power-path control.
