DRV8876-Q1: VCP voltage, CPH/CPL voltage

IK HYUN SHIN

Part Number: DRV8876-Q1

Belows are schematics for DRV8876-Q1

There's no software, only input 12V to VM pin

PIN(VM, VCP, CPH) = 12V

Q1) What is the normal voltage range of VCP?

12V of VCP is right?

Q2) What is the normal voltage range of CPH?

12V of CPH is right?

Hello,

Something is not right. Is nSLEEP = HIGH?

From the datasheet:

nSLEEP = low(0V)

Is the 12V of VCP is right?

It's just 12V input to VM pin.

There is no other conditions(No communication with other IC's)

Hello,

In the sleep state, the charge pump is disabled, so VCP ~= VM.

Ryan
