Product details

1.2A max charge current — thermal design matters

At 1.2A charge current with a 10V supply max, the linear regulator drops the difference between input and battery voltage as heat. The 20-HTSSOP with exposed thermal pad (PowerPAD) is sized for that dissipation, but PCB layout must provide a low-thermal-resistance copper plane under the pad. Designs charging at the full 1.2A should budget for several watts of heat; lower charge current via the programmable feature reduces thermal stress and extends component life.

It is ROHS3 compliant.

Frequently asked questions

Can BQ24001PWP be used with a 4.2V Li-ion battery?

Yes, the BQ24001PWP is designed for a 4.2V battery pack voltage and supports standard single-cell Li-Ion and LiPo chemistries.

What are the recommended alternatives or cross references for BQ24001PWP?

No pin-compatible alternative is listed in the available documentation. For a similar function, consider other single-cell Li-Ion linear chargers in the TI BQ240xx family, but verify pinout and package compatibility from the respective datasheets.
