Hi Manikandan,
You may want to check our Brushed and Brushless DC motor drivers portfolios, DRV2511-Q1 may be useful as well but it is mainly purposed on solenoid and haptic actuators.

Ok thank you for your information, can you suggest any inbuilt DAC feature with solenoid and voice coil driver IC , because we are operating the motor through PWM only so can you any IC suitable for my requirement . i attached our existing driving circuit image for your reference, now are trying to optimize the circuit. if the integrated IC's are available , we can eliminate the more components and assembly cost.
Hi Manikandan,
Thank you for the details.
Let me clarify on DRV2511-Q1; this device still needs an analog input signal to drive the motor or voice coil, it is not generating signals on its own.
If you need a device that is able to generate signals you may want to check DRV26x5/DRV26x4, these have an integrated library and the effects can be triggered through digital interface or a GPIO.
You mentioned DAC feature, what is the digital signal you can send to the driver? It may be possible to drive the voice coil with an audio amplifier but the digital interface has to be I2S, TDM or similar.

Hi Manikandan,
Just checking if we can close this thread, please let us know if there is any update.

Thank you for your replay,
Actually our application is solenoid valve driver for ventilator, so we need individual input and o/p channel for the driver.
still DRV2511-Q1 needs 4 GPIO's to drive the single valve. please suggest direct PWM control with feedback loop.
For ex: if we are PWM with 50% duty cycle, the driver should release half of the input supply. i saw the DRV8876 but its not available on the market. can you suggest suitable part or alternate part for the same.
