DRV2510-Q1: How does it operate by IN+ input, IN- input, and FREQ_SEL register?

Yoshiki Ochi

Part Number: DRV2510-Q1

Hi team,

Could you tell me How it operates by IN+ input, IN- input, and FREQ_SEL register?
I could not find any truth table or relationship among IN+, IN-, OUT+, OUT-, or their PWM duty.

Hello Ochi-san,

The IN+/- inputs are used to input the desired haptic effect in the form of a PWM or sine wave. The FREQ_SEL register is used to determine what the PWM switching frequency will be (400 or 500kHz) for the gate driver.

Hi Beigel,

Does "The IN+/- inputs are used to input the desired haptic effect in the form of a PWM or sine wave" mean that IN+/- duty is as same as OUT+/- duty?
Or does the IN+/- voltage amplitude and its gain affect OUT+/- PWM duty?
Do you have any formula for them?

Regards,
Ochi

Hello Ochi-san,

The voltage and gain will only impact the level of the output not the PWM duty.
