HT45R7130
Power Inverter OTP MCU
General Information
The device is an OTP type 8-bit high performance RISC architecture microcontroller, which includes multiple gate-driver circuits for driving N-channel MOSFETs, designed for Power Inverter applications.
For memory features, the device is supplied with One-Time Programmable, OTP memory. Other memory includes an area of RAM Data Memory.
Analog features include a multi-channel 12-bit A/D converter, an Over Current Protection function, an Over/Under Voltage Protection function and multiple internal input divider resistor circuits. With regard to internal timers, the device includes multiple and extremely flexible Timer Modules providing functions for timing, pulse generation and PWM generation operations. Communication with the outside world is catered for by the inclusion of fully integrated SPI and UART interface functions, two popular interfaces which provide designers with a means of easy communication with external peripheral hardware. Protective features such as an internal Watchdog Timer and Low Voltage Reset coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.
The device also includes fully integrated high and low speed oscillators which require no external components for their implementation. The ability to operate and switch dynamically between a range of operating modes using different clock sources gives users the ability to optimise microcontroller operation and minimise power consumption.
The inclusion of flexible I/O programming features, Time-Base function, LDO along with many other features further enhance device functionality and flexibility. The device also includes an 8-bit high resolution PWM output, which together with the over voltage/under voltage protection circuit can automatically adjust the duty cycle, to implement an auto-adjust closed loop control system. The PWM output can select either complementary output or push-pull output to meet different application requirements, especially suitable for Power Inverter boost control.
