Eric,
I found an E2E post that explains what you are seeing. The 600ohm impedance matches very close to your measurements in terms of current and the voltage divider that is created by the 300 and 600 ohm resistor.

Part Number: DRV8872 Other Parts Discussed in Thread: DRV8871 , DRV8870 , Hi, Team
What's the frequency of integrated charge pump of DRV8872-Q1?
Customer has concern on EMC.
Is this part equipped with spread spectrum or other technology for better…
Part Number: LMR36015-Q1 Other Parts Discussed in Thread: DRV8872-Q1 , Hi there,
Is there a specified value for the maximum current capability of the integrated MOSFETs body diode?
Best Regards,
Christian
Part Number: DRV8872 We use DRV8872-Q1 in Self-locking charging gun.The device can't load by Electronic load,but it is nomal by resistance and relay,the upper bridge is directly to low bridge once connect Electronic load.
Hi Mattia,
Please refer to e2e.ti.com/.../2063645 for more details.
The DRV8870, DRV8871, DRV8872, and DRV8872-Q1 all have similar output structures. The outputs will act similarly to high voltage on the outputs when in sleep mode, trying to protect…
Hi Ryuji-san,
There is not a device that is directly compatible. The DRV8872-Q1 can be used with some additional circuitry.
The device may require additional circuitry, but the 1k pricing appears to be less.
Hi James,
Thank you for the pointers
--> I see only DRV8872DDA in the catalog how much is DRV8872-Q1 different ?
--> Also the stall or over current protection seems to work only at OCP >1.2A in DRV8873C, what if i want to configure it to a particular…
Hi Charles,
There are several devices to consider, although the 6V to 7V operation may prevent use of two.
1) The DRV8873-Q1 operates between 4.5 and 38V, and is available with either a hardware or SPI interface.
2) The DRV8801A-Q1 operates between…
Part Number: DRV8872 Hi Dear colleague,
My customer is using our DRV8872-Q1 and have several quiescent questions about this device
1. What's the current consumption when device is in brake mode( IN1=1, IN2=1), customer find that it is up to 2mA…
