Active production – BQ24192RGET sourcing note
This is a current production part, not subject to a last‑time‑buy notice. The base product number is BQ24192.
4.5 A charge current and I²C programmability
Designed for single‑cell lithium‑ion and lithium‑polymer batteries, the BQ24192RGET delivers a programmable constant‑current charge up to 4.5 A max. The I²C interface allows the host controller to adjust charge current, termination threshold, and timer settings on the fly — a practical advantage when the same charger must support different cell capacities across a product family. Input voltage tolerance extends to 17 V max, which covers standard USB‑C PD adapters and common 5 V/9 V wall warts without an external pre‑regulator. The integrated fault protection monitors overcurrent, overtemperature, and overvoltage conditions, reducing external component count.
Industrial temperature grade and QFN package
The 24‑VQFN (4 mm × 4 mm) exposed‑pad package (supplier device package 24‑VQFN) provides a low thermal resistance path to the PCB copper plane, which is essential when sustaining 4.5 A charge current without thermal foldback.
BQ24192 vs BQ24192RGET – packaging difference
The base product number BQ24192 covers multiple package variants. For a BOM already laid out for a 24‑VQFN charger, the BQ24192RGET is the correct order‑code match.
