Hello Team,
customer see leakage current sinking into OUT pins even when tri-state.
Is there a specification available for this current?
Background: There is a supercap storage behind this driver and this leakage will dis-charge the cap.
Many Thanks
Josef
Hi,
Thank you for your question. Motor driver should have some leakage on OUTx pin.
New Generatation device(DRV8242-Q1) has SPE of OUT impedacne as follows.
Previous generation of DRV8874Q1 does not have SPEC and data what I can provide for OUTx leackage or impedance.
Motor driver normally does not care leakage on OUTx pin, therefore SPEC was not available in previous gen device. Please expect some amount of leakage current. It is issue on system, may need blocking diode externally

Shinya Morita
