DRV8837: About VM current at some mode

Part Number:DRV8837

Hello,

Regarding to VM current on DRV8837, my customer is asking some question.

(Question)

(1) When VCC<1.7 V (VCC undervoltage), the device enters a low-power state and

VM current(Ivm:=40uA(typ)）gets lower more.

My understanding is correct?

(2)When VCC doesn't supply and only VM supply , is there any impact on this device?

(3) When the condition(mode) is as following, how many milliampere will be VM consumption currents?

(All mode is on 100% duty cycle drive)

　･No_PWM 40～100uA_max

　･Reverse/Forward

　･Brake

　･Coast
