® RT9527A Single Cell Li-Ion Battery Charger with Adjustable Charging Current for Portable Applications General Description The RT9527A is a low cost single-cell Li-ion charger for low current charge applications. The RT9527A can be powered up from an AC adapter or USB (Universal Serial Bus) port inputs. The RT9527A enters sleep mode when VIN power is removed. The RT9527A optimizes the charging task by using a control algorithm, which includes pre-charge mode, fast-charge mode and constant voltage mode. The charging task is kept in constant voltage mode to hold the battery in a full charge condition. The charge current is adjustable via an external resistor. The internal thermal feedback circuitry regulates the die temperature to optimize the charge rate for all ambient temperatures.
