Part Number: DRV120 Other Parts Discussed in Thread: DRV8908-Q1 , DRV8434E Does TI have a Multi Channel Relay, Solenoid, Valve Low-Side Driver With Current Regulation? I am looking at the DRV120 but it is a single channel and I want a multi channel device…
Part Number: DRV120 Other Parts Discussed in Thread: DRV110 , Hi, I have the same issue and wish to limit the hold current to15 mA. The answer that was previously posted is for the DRV110 not the DRV120 since there isn't a Rsense on the actual DRV120…

Hi team,
Good day!
We need your help regarding the attached file which has some missing parameters kindly provide those values highlighted with question marks. We need your help regarding the attached file which has some missing…
Part Number: DRV120 Other Parts Discussed in Thread: DRV103 , DRV110 As per the data sheet its mentioned that we need to provide PWM signal to control the solenoid valve. Is it possible to turn on/off solenoid valve by providing GPIO signal to the input…
Part Number: DRV120 I recently had a DRV120 show a fault condition.
I measured the OUT pin to ground and measured 18.5kOhm for the failed part.
On a working circuit I usually measure OUT to ground around 2.4MOhm.
We have an application where the…
Part Number: DRV120 Other Parts Discussed in Thread: DRV110 , We are using three Staiger spider microvalve VA 204-508 24V with three DRV120A valve drivers. I have a Peak current set of 100mA and a hold current of 50mA.
Rpeak - 162k
Rhold - 133k

Part Number: DRV120
A customer I support is looking for a driver that can drive solenoids from 5 to 24V @ 100mA (200mA current limit).
Since the DRV120 is an open drain driver, is it OK to power the device itself from a voltage rail that is within…
Part Number: DRV120 Other Parts Discussed in Thread: DRV110 Can the Vin of the DRV120 be +12V while the Vs driving the solenoid be +5V?
It's current sensing the solenoid voltage so Vin doesn't play a roll, does it?
Any effect on the calculations for…
Part Number: DRV120 Hello
We are evaluating DRV120 for positioning of the solenoid valve. The idea is to use DAC output form the MCU to control the hold current as described here:
What would be the limit for the achievable resolution for the hold…
Hi gotmilk,
It is never recommended to open circuit an inductor while it's charged. Doing so typically generates kilovolts in order to maintain continuity of the inductor's current. That said, it is no surprise that the DRV120 failed. In your application…
