Features

required to interface to each of the MOSFETs is not increased since these control lines may also be paralleled. In this application note a single PIC16F873 (Microchip) microcontroller was used to control four ICON HBridge modules. An analog-to-digital converter (ADC, internal to the PIC16F873) was used to establish a pulsewidth-modulation duty-cycle (PWM, also internal to the PIC16F873) to control four ICON H-Bridge modules connected in parallel. The system was configured for unidirectional speed control and was tested at 24V with a resistive load of 0.389Ω. A custom PCB was designed to carry .
