When compared with the first generation HT45F85xx series, these new devices also have Li-battery voltage detection circuitry with an accuracy of ±24mV, new add zero standby power consumption function, passive balance circuitry, high voltage MOSFET gate-drivers in addition to other functions. One additional special feature is that the internal LDO now has an increased output current capability of up to 50mA. The devices are suitable for 3 to 8-cell Li-battery products, such as BMS boards, power tools, wireless vacuum cleaners and so on.
The devices contain 8K×16/16K×16 of Flash Program Memory, 512×8/1024×8 of Data Memory and a 128×8/1024×8 EEPROM as well as 21/25 multi-function I/Os. Each device includes a 12-bit multi-channel A/D converter and a comparator function.
