  • DRV103: Choosing higher cap values for bypass/decoupling capacitor

    TI Thinks Resolved
    Part Number: DRV103 Tool/software: Can I use a higher bypass/decoupling capacitor instead of the recommended 22uF? I am thinking of using 100uF 35V tantalum or aluminum electrolytic. The DRV103 will be used to drive a solenoid. This 100uF would actually…

  • DRV103: DRV103 Powerpad connection to ground

    Part Number: DRV103 hello, I used DRV103H in my design, in layout, power PAD via's are connected to the ground, would it make any effect on functionality of the design? first image is viewed from ground layer. purple color is GND and orange color is…

  • DRV103: drv103u is not giving right duty cycle.

    Part Number: DRV103 Hello, I am Using drv103u to control the proportional valve using microcontroller, valve ratings: 24V , 7watts, 290mA , 82 ohm resistance. I tried the circuit like figure 18 in the datasheet, but I get 100% duty cycle if I ask for 50…

  • DRV103: Duty cycle of PWM Signal not accurate as per datasheet declared resistor value

    TI Thinks Resolved
    Part Number: DRV103 Hi Team, Good Day... This is Kirubakar Nagarajan from Rotork Controls Limited. I have implemented DRV103H IC for solenoid driving with 50% duty cycle. I have used 215K resistor for setting IC oscillator frequency @ 24KHz and 137K Resistor…

  • DRV103: DMOS shorted sometimes, depending on power supply.

    Part Number: DRV103 Hi, We are using the DRV103U to power a DC solenoid that is 58 Ohm and 24 V (400 mA draw). For the most part the DRV103U circuit works fine. However, the circuit will fail with the inner transistor power DMOS shorted sometimes . It…

  • DRV103: Maintain 100% duty cycle.

    Resolved
    Part Number: DRV103 In order to permanently maintain a 100% duty cycle for OUT, is it OK to connect the "Delay Adjust" pin directly to ground such that it always stays below the 2.6V threshold? We have found that a large enough resistor on the…
