DRV2510-Q1: LT spice model or unencrypted Pspice model

Devin Zhang
Prodigy 20 points
Part Number: DRV2510-Q1

Hi Ti experts,

We want to create the simulation with LTspice, but I can not find the corresponding model in your official website. there is only the encrypted Pspice model can be downloaded.

So if possible to provide the LT spice model  or unencrypted Pspice model for DRV2510-Q1 to me. Thank you!

Additional, what is the requirements for the IN+ and IN-(differential PWM), for example frequency and duty cycle etc.

How the input -> IN+ and IN-  to effect the haptic(voice coil) performance?  I have capture the IN+ IN- with the oscilloscope, I found that the IN+ and IN- wave is the same no matter what the voice coil to work or not work.

    Hi,

    DRV2510 is based on TAS5421 audio amplifier. you can use the TAS5421 TINA_TI spice model 

    the DRV2510 is an analog input device. the inputs should not be exposed directly to PWM. the host processor can output PWM, then pass through low pass filter to leave an audio frequency analog signal. PWM frequency and low pass filter configuration are up to the user. you can use the EVM for reference.

    OUT+ and OUT- should track IN+ and IN- respectively. If you are having occasional issues you should check register 0x01 to see if there is any fault condition being reported
