Overview

Description

BQ25620RYKR is Texas Instruments’ single‑cell Li‑ion battery charger with integrated power‑path management. It accepts a USB 5V input and charges a 1‑cell Li‑ion battery while simultaneously supplying the system load, using a high‑efficiency switching charger and a programmable charge profile (pre‑charge, constant‑current/constant‑voltage, termination). Key features include adjustable charging current (via PROG/ISET), fixed regulation voltage around 4.2V, and comprehensive protections (overcurrent, overvoltage, short‑circuit, thermal, undervoltage, etc.). It provides system/battery monitoring through status pins and simple control interfaces. The RYKR suffix denotes the RoHS, tape‑and‑reel packaging (8‑pin package). Typical applications: portable devices, wearables, USB‑powered gadgets, and other battery‑powered peripherals. For exact electrical specs, pinout, programming options, and safety features, consult TI’s data sheet and product page for BQ25620.
