Technical Details & Description

The BQ24103ARHLR: It is ROHS3 Compliant, clearing regulatory requirements for EU and global markets.

Battery chemistry and charge profile

This charger IC is designed for Lithium Ion/Polymer batteries, supporting 1 or 2 series cells with a battery pack voltage of 8.4V. The maximum charge current is 2A, and it is constant — programmable via an external resistor, so the designer sets the charge rate to match the battery capacity. Programmable features include current and timer, allowing the charge profile to be tailored for the specific cell chemistry and capacity.

Supply voltage and input headroom

The maximum supply voltage is 16V, giving headroom for charging from common input rails such as USB (5V), 12V adapters, or unregulated wall warts.

Protection and temperature range

Built-in fault protection covers over-temperature and over-voltage conditions, safeguarding both the charger IC and the battery during fault events.

Frequently asked questions

What is the maximum charge current and battery pack voltage for BQ24103ARHLR?

The maximum charge current is 2A, and the battery pack voltage is 8.4V, supporting 1 or 2 series Li-Ion or Li-Polymer cells.

What compliance documentation does Texas Instruments provide for BQ24103ARHLR?

The BQ24103ARHLR is ROHS3 Compliant, meeting the EU RoHS directive for lead-free and restricted substance requirements.
