The SY6103 is a linear charging management chip that integrates path management and a maximum charging current of 500mA. It integrates an I2C communication module, allowing the host to flexibly configure charging parameters, obtain charging status, and report relevant interrupts.
The SY6103 can complete the entire charging process for lithium-ion or lithium-polymer batteries, including pre-charging, constant current, and constant voltage charging. It can also automatically recharge when the battery voltage drops. The integrated path management function prioritizes system power supply, ensuring that the system power supply voltage requirements are met even when the battery is over-discharged. It is plug-and-play.
The SY6103 integrates comprehensive reset functions, including watchdog timer reset for charging and discharging, key reset, one-key register reset, and cold reset for convenient software upgrades.
The SY6103 uses a 1.725mm x 1.725mm 9-Ball WLCSP package.
