Page 1 of 2 PWM driver click From MikroElektonika Documentation If you need to control DC motors with loads up to 10A, PWM driver click is the perfect solution, thanks to the Silicon Lab Si8711CC one-channel isolator. It communicates with the target MCU over PWM pin, and runs on a 5V power supply. It can be used in a wide variety of ways, from controlling light intensity to serving as an ON/OFF switch to control DC load circuits. PWM driver click Contents ◾ 1 Features and usage notes ◾ 1.1 MOSFET transistor ◾ 1.2 Onboard screw terminals ◾ 1.3 Key features ◾ 2 Pinout diagram ◾ 3 Additional information about the click ◾ 4 Programming ◾ 5 Resources PWM driver click Features and usage notes IC/Module Si8711CC datasheet (http://www.silabs.com/Support% 20Documents/TechnicalDocs/Si87xx.pdf) MOSFET transistor The click contains a P-channel DMP3010LK3 MOSFET transistor. When the click is used for PWM control it is not recommended to use it with loads of wattage over 50W because the MOSFET chip can get overheated. However, this does not apply when the click is used as an ON/OFF switch. Onboard screw terminals There are two pairs of screw terminals on the PWM driver click — one for the external power supply and one for the DC load.

Designator Name Type (LED, BUTTON…) Description LD1 LED PWR Power LED CN1 EXTPWR CONNECTOR External power supply connection CN2 LOAD Load connection CONNECTOR Programming This demo demonstrates the change of light intensity of a halogen lamp; using the on-board potentiometer P1 (EasyPIC 7), you can regulate the light intensity. For this demo we have used the EasyPIC v7 development system. ◾ Supply voltage within range of 3 – 30 V. ◾ Maximum output current detected: 15 mA. ◾ Wide operating temperature range: –40 to +125 °C ◾ Demo available for: ARM, PIC, PIC32, AVR and FTDI compilers. This snippet shows the initialization of MCU (PWM and required port pins) and LCD. In an endless loop, we are reading current digitized value from ADC channel 1 and showing it's value with light intensity. Also, luminosity percentage is given on the LCD. 1 void main() 2 { 3 MCU_Init(); // Configure PORTB pins as digital 4 Lcd_Init(); // Initialize Lcd 5 Lcd_Display(); // Display text 6 current_duty = 0; 7 PWM2_Start(); 8 PWM2_Set_Duty(current_duty); 9 while ( 1 ) // Playing with Potentiometer P1 you can control current PWM duty cycle 10 // For visual result, look at LED PC1 11 { 12 uint8_t cur_duty_byte; 13 14 // Read 10 - bit ADC value and set newly acquired 8 - bit PWM duty 15 adc_rd = ADC_Read(1) & 0x0000FFFF; 16 current_duty = adc_rd / 4 ; 17 cur_duty_byte = LoWord(current_duty); 18 PWM2_Set_Duty(cur_duty_byte); // Set newly acquired duty 19 cur_duty_byte = cur_duty_byte * 0.39; // 100 / 256 20 ByteToStr(cur_duty_byte, txt); 21 Lcd_Out(2, 11, txt); 22 Delay_ms( 20 ); 23 } 24 } 25 Resources ◾ ◾ ◾ ◾ PWM driver click schematic (http://cdn-docs.mikroe.com/images/c/c2/PWM_driver_click_schematic_v100.pdf) Si8711CC datashet (http://www.silabs.com/Support%20Documents/TechnicalDocs/Si87xx.pdf) MOSFET datasheet (http://www.diodes.com/_files/datasheets/DMP3010LK3.pdf) mikroBUS™ standard specifications (http://download.mikroe.com/documents/standards/mikrobus/mikrobus-standard-specification-v200.pdf) Retrieved from "http://docs.mikroe.com/index.php?title=PWM_driver_click&oldid=3136" Category: Home page ◾ This page was last modified on 9 January 2017, at 14:09. ◾ Content is available under Creative Commons Attribution unless otherwise noted. http://docs.mikroe.com/index.php?title=PWM_driver_click&printable=yes 1/20/2017
