# BQ25620RYKR (Component)
## Description
Charger IC Lithium Ion/Polymer 18-WQFN-HR (3x2.5)
The BQ25620RYKR is a highly integrated standalone switch-mode battery charge management and system power-path management device designed for single-cell lithium-ion and lithium-polymer batteries. The device integrates a synchronous buck charger, power-path management, input current optimization, and system regulation functions into a compact package suitable for portable and battery-powered embedded systems. It supports USB and adapter power sources with high-efficiency charging operation and dynamic power management for optimized thermal and power performance.
The device includes integrated MOSFETs, charge termination, safety timers, input overvoltage protection, thermal regulation, and battery temperature monitoring. It supports I²C communication for programmable charging parameters, system monitoring, and fault reporting. The integrated narrow-voltage DC architecture improves efficiency while reducing external component count and PCB area.
