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…
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…
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…

This post is a continuation of the question asked by Nathan C in " DRV103: Connecting ground to PowerPAD ". I, Nathan D (Don't worry I'm a different human, not just the next Android model…
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…
Part Number: DRV103 I'm looking for Application Bulletin SBFA002 referenced in the DRV103 datasheet but it doesn't come up on a webpage search. Do you have a copy of this document?
Thanks;

Hello,
Thank you for elaborating on your intended use case.
Can you confirm this behavior is occurring across multiple devices?
Best Regards,

Team,
I saw the below answer already related to the plane the SOIC powerpad should be connected to: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/908044/drv103-connecting-ground-to-pow…
Part Number: DRV103 Other Parts Discussed in Thread: DRV104 Hi Team,
We have tried all your suggestions and from our end also we reverified our design and re-spin the PCBA as well. We couldn't see any difference in PWM Output, output is continuously turned…
Hi Hossam,
Would you be able to probe the voltage at VS pin (directly at the pin) and also the INPUT pin to make sure the device is getting the voltage correctly? Also make sure the INPUT pin voltage is above 2.2V.
If possible, if you can connect the…
