The RT9527J/JH/JA is a low-cost single-cell Li-ion battery charger for low charge current applications.
The RT9527J/JH/JA can be powered via an AC adapter or USB port and enters sleep mode when power is removed. It uses a control algorithm to optimize charging, featuring pre-charge, fast-charge, and constant voltage modes. The device maintains the battery in a fully charged condition by consistently operating in constant voltage mode. Charge current can be adjusted with an external resistor. Internal thermal feedback regulates the die temperature to optimize charge rates under varying ambient conditions. The device supports a maximum VIN of 28V and features both undervoltage and overvoltage protection for the AC adapter input.
The RT9527J/JH/JA is available in the WDFN-8L 2x2 package. The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
