MCT8316Z: How the dual charge pump works

Hi Annie,

Here is the datasheet description on the output power stage: 

The MCT8316Z device consists of an integrated 100-mΩ (combined high-side and low-side FET's on-state resistance) NMOS FETs connected in a three-phase bridge configuration. A doubler charge pump provides the proper gate-bias voltage to the high-side NMOS FET's across a wide operating-voltage range in addition to providing 100% duty-cycle support. An internal linear regulator provides the gate-bias voltage for the low-side MOSFETs. The device has three VM motor power-supply pins which are to be connected together to the motor-supply voltage.

Hope this helps.

Best,

Robert
