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…

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

Hey Allen,
8.2.2.1 Current Limiting Resistor Selection helps explain it a bit, "The Zener clamping voltage of the DRV110 device starts dropping from its ideal 15 V at temperatures greater than 45°C when the EN pin is pulled low. Applications that leave…
Part Number: DRV110 Hello, how is Rhold calculated? given: Rsence = 2 ohms, Ihold = 65mA, Ipeak = 200mA .
I review the calculation in the datasheet, and it not sinking in.
thanks
Part Number: DRV110EVM Hi,
I am using DRV110EVM board to drive a 24V/10W solenoid. One of the required parameter is Rosc which is used to set the frequency PWM.
Can someone please explain what parameters are used to define the frequency?
Thanks.
