BQ24701PW

Battery Chargers Overview

The BQ24701PW is a notebook PC battery charge controller and system power selector manufactured by Texas Instruments. It supports multi-chemistry batteries and operates with a maximum supply voltage of 20V. The device utilizes dynamic power management to optimize charge times and includes an integrated selector for system power routing. It is housed in a 24-TSSOP surface-mount package and functions within a temperature range of -40°C to 85°C.

Battery Chargers Feature Summary

• Dynamic Power Management (DPM) minimizes battery charge time by maximizing available wall-adapter power through current adjustment.
• Integrated system power selector supports battery conditioning, smart battery learn cycles, and break-before-make transitions.
• Zero-volt operation capability allows charging of deeply discharged or depleted batteries.

Battery Chargers Applications

• Notebook PC battery charging systems
• Sub-notebook PC power management
• Multi-chemistry battery charger controllers

Battery Chargers Procurement Notes
