3A single-cell Li-Ion charger with I²C programmability
The Texas Instruments BQ24262RGER is a single-cell Li-Ion battery charger IC that delivers up to 3A programmable charge current via an I²C interface, housed in a 24-VQFN (4x4) package.
I²C interface — what it means for system integration
The I²C interface allows a host microcontroller to dynamically adjust the charge current and monitor fault conditions, enabling adaptive charging profiles that a fixed-function charger cannot match. The 6V maximum supply voltage and 4.2V battery pack voltage target single-cell Li-Ion applications common in portable and handheld equipment.
Obsolete — sourcing reality for BQ24262RGER
Availability is limited to independent-distributor inventory and surplus stock.
24-VQFN (4x4) — footprint and thermal considerations
The 24-VQFN (4x4) package with exposed thermal pad requires a PCB land pattern that connects the pad to a copper plane for heat dissipation, especially at 3A charge current.
