DC Motor Driver ASSP MCU

Holtek has added the HT45F4630 dc motor driver ASSP MCU. The device is a Flash Memory type 8-bit high performance RISC architecture microcontroller with integrated functions for dc motor driving applications. Offering users the convenience of Flash Memory multi-programming features, this device also includes a wide range of functions and features. Other memory includes an area of RAM Data Memory as well as an area of EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc. The device is especially suitable for battery powered products such as electronic locks, safes, toys, alarms etc.

Analog features include a multi-channel 12-bit A/D converter and an operational amplifier. The HT45F4630 includes multiple and extremely flexible Timer Modules providing functions for timing, pulse generation and pwm generation functions. Protective features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.

A full choice of various external and internal low and high speed oscillator functions is provided including a fully integrated system oscillator which requires no external components for its implementation. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimize microcontroller operation and minimize power consumption.

Communication with the outside world is catered for by including a fully-integrated I2C interface, this popular interface which provides designers with a means of easy communication with external peripheral hardware. Also the inclusion of flexible I/O programming features, Time-Base functions and external interrupts along with many other features further enhance device functionality and flexibility for wide range of application possibilities.

This HT45F4630 contains a high voltage driver control circuit and a high voltage driver combination circuit as well as high voltage power supply detection and over current protection functions which can be used in different motor driver applications.
