The INJOINIC IP5209T is a PMIC (Power management integrated circuit) with Battery Management QFN-24 RoHS. It is a low-power chip designed for monitoring and protecting Li-ion batteries installed in mobile devices and other portable electronics. It contains a buck-boost converter for efficient charging of the battery and a battery fuel gauge for accurate reporting of charge status and runtime estimation. The chip also contains reverse-current protection, over-temperature protection, over-current protection, and under-voltage protection for safe and reliable battery operation. Its small QFN-24 package makes it suitable for space-constrained applications, where a minimum PCB footprint is required.
