It regulates the charge voltage to 8.4V and delivers a constant charging current programmable up to 1.2A. A programmable safety timer prevents overcharging if the termination current is never reached, and the built-in over-temperature protection shuts down the pass element if the die exceeds the safe junction limit. ## Charge current and pack voltage — sizing the power path The 1.2A maximum charge current sets the heat dissipation floor in the linear pass element. At 1.2A with a 5V input and an 8.4V pack, the dropout across the pass transistor is about 1.6V, so the thermal power is roughly 1.9W. The 20-HTSSOP with its exposed thermal pad needs a good copper pour and vias to keep the junction below the 125°C absolute maximum during a full charge cycle. For faster charging than 1.2A, you would need a switching charger — this part is a linear regulator, so the current limit is thermal, not electrical. The 8.4V full-charge target matches the standard termination voltage for two Li-ion cells in series. If the pack chemistry is LiFePO4 (3.6V per cell nominal) or the cell count is different, this charger will overvoltage the battery. Confirm the pack configuration before committing the BOM line. ## Package and thermal management Surface-mount assembly requires a solder-paste stencil aperture covering at least 50% of the pad area for reliable solder-joint formation and heat transfer. ## Lifecycle and sourcing posture No pin-compatible second source or official replacement is listed in the TI documentation.","metaTitle":"BQ24006PWPR Li-Ion Charger IC, 1.2A Max, 2-Cell, 20-HTSSOP","metaDescription":"Texas Instruments BQ24006PWPR linear Li-Ion charger IC.

The BQ24006PWPR is specifically designed for a 2-cell series Li-ion pack. The over-temperature protection and safety timer guard against fault conditions during the charge cycle."},{"question":"What is the maximum charge current for BQ24006PWPR?","answer":"The maximum charge current is 1.2A. The charge current is programmable via an external resistor, so the actual current can be set lower to match the battery's C-rate or to stay within the thermal budget of the PCB layout."},{"question":"Is BQ24006PWPR obsolete?","answer":"No. The product status is listed as active."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24006PWPR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24006PWPR when reusing this data.
