DRV3901-Q1: Current consumption

Vishwas H R

Part Number: DRV3901-Q1

Tool/software:

Hello,

What is the maximum current consumption of each pin PVDD, VREG and VDRV with all functionality and diagnostics on except deployment?

During deployment I understand there are different configurations and that is clear to me but wanted to know current when there is no deployment.

Thank you,

Hi Vishwas,

Thanks for the followup.

In the system, battery voltage (typical 12V) will be connected to PVDD, VREG and VDRV each pin isolated by diode as shown in the diagram. So the current consumption is finally going to come from PVDD.

During the standby state without diagnostics the current consumption is specified as follows

During the diagnostics running the current profile on PVDD will be similar to the load current profile shown below. The average current will depend on how often and what all tests are run in the diagnostics.

Thanks,

Ibinu

Hello,

I can see Rload monitor measurement can consume approx 40mA. Can I know what is the time period of each slot and also how current and time was derived/ assumed?

Thank you,

Hello Vishwas,

The time for each diagnostic is configurable with the OFF_DIAG_xxx_TSEL bits. Please see options for R_LOAD test:
