VNH5019A-E circuit diagram configuration

[Oido]

Hello, I am designing a circuit using VNH5019A-E motor driver.
Is there a problem if the capacitor is installed on the motor output pins OUTA and B? The value is about 10uF.

For example, the charging and discharging of the capacitor leads to situations where low speeds such as PWM 10% and 20% cannot be controlled.

Is it possible to not use capacitors for the output? If possible, to what extent is it possible? This is to remove the noise from the EMC/EMI test.

 

Additionally, is it correct that this motor driver can't use PWM 100% because it has H bridge structure? Because it requires switching of high side and low side FET? If so, if I set it to 100% and give the PWM signal, does it operate at 99%?? Or does it operate incompletely? For example, it generates noise..

Are you sure you mean the VNH5019A-E?

The VNH5019A-E is an H-bridge motor driver that drives a motor directly via OUTA and OUTB – why do you think you need a capacitor for that?

The motor driver can do 100% PWM because it does not need boost capacitors on the half-bridges.
