Compared with the HT45F5Q, this new device has added resources with its higher capacity Flash Program Memory, Data Memory, I/O ports and Timer Modules as well as a higher resolution 12-bit Charger Management Module D/A converter to acheive higher accuracy charging voltages and currents. The device also supports dynamic temperature compensation.

An automatic USB detection function is also included which offers support for Quick Charge 2.0 which is used in fast charger applications. With its programmable I/O output current and LCD Driver the device has added value in being suitable for charger products with LED/LCD displays.

By using specific charger production fixtures, both the charging voltage and current correction parameters can be written to the device's internal EEPROM, which can offer savings over the traditional manual correction techniques, thus offering major production efficiency advantages.

With regard to device packaging the HT45F5R is supplied in both 24 and 28-pin SSOP package types, making them suitable for LED/LCD display charger products.
