Part Number: DRV110 Tool/software: Hello,
I am trying to operate a contactor coil with DRV110APWR. I want the current to be around 60ma and the operating voltage should be from 80v to 250V. I have tried several combinations for Rosc and Rhold to stabilise…

Hello,
I use a DRV110 for driving a solenoid, with a peak current of 5A and a hold current of 2A. The currents measured are correct, but I have an issue with the keep time. When the part is cold, at room temperature…
Part Number: DRV110 Hi team,
can you please specify how the maximum oscillator frequency on drv110 can be set.
There are different infos on the DS compared to this reference design

Part Number: DRV110 Hello, I use DRV110 in my design and have noticed something strange. The issue is related to Keep Time setting. When I used Vin of 12V the setting of the Ckeep capacitor was very accurate, with 2.2uF I got ~220ms. Switching to 28V input…
Part Number: DRV110 Other Parts Discussed in Thread: TINA-TI Hi Team,
Hello, according to the specification of the chip, under the condition that the PEAK and HOLD pins are directly connected to GND and RSENSE = 1 ohm, the lower limit of the current deviation…
Part Number: DRV110
Hello, with Rosc = ~160k an audible hissing noise can be heard, replacing Rosc with a ~64k, the hissing noise is minimized.
With Rosc set to 64K, what are the ramifications? Does the Higher Osc frequency result in a fixed PWM?

Part Number: DRV110 hi:
Regarding the DRV110APWR chip, we have found during application testing that there may occasionally be situations where it does not excite and enters the hold state directly. The measured waveform is as follows
Yellow: VCC
