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.
