Product details

The Texas Instruments BQ24618RGET is a synchronous buck battery charger IC for lithium-ion and lithium-polymer packs, handling 1 to 6 series cells with a maximum charge current of 10A and a battery pack voltage up to 26V. It operates from an input supply up to 28V, giving headroom for 24V adapters and their ripple. The constant-current, constant-voltage charging profile is programmable via external resistors, and a timer provides backup termination. Integrated fault protection covers overcurrent, overvoltage, overtemperature, and short-circuit conditions, which simplifies the safety compliance paperwork on the end product.

10A charge current and the thermal reality

The 10A max charge current is the headline number that determines whether this part fits high-capacity packs in power tools, e-bikes, or backup battery systems.

This is a current-production part, not a last-time-buy or NRND situation.

Frequently asked questions

What is the maximum charge current of BQ24618RGET?

The BQ24618RGET supports a maximum charge current of 10A, programmable via an external sense resistor. This makes it suitable for charging high-capacity Li-ion and Li-Polymer battery packs in applications like power tools, e-bikes, and portable medical equipment.
