MCT8316Z: Chip using spi configuration register problem

Annie Liu
Genius 10295 points
Part Number: MCT8316Z
Other Parts Discussed in Thread: DRV8316

Hi Team,

Customer would like to know:

1. What is the difference between MCT8316Z and DRV8316?

2. Could he program and send a 16-bit data directly to MCT8316 to configure related registers?

3. If he can send data directly when using spi to configure the chip registers, is the parity bit written in the manual a parity check? If he wants to read the status register of this chip, can he write the data format that spi wants to send to it?

Thanks,

Annie

    Hello Annie,

    MCT8316Z is a device that integrates sensored trapezoidal control, while DRV8316 does not have any motor control integrated (only a power stage).

    The MCT8316Z that we released in Advanced Product Launch is hardware only (PMCT8316Z0TRGFR). There is a SPI version of the IC described in the datasheet but it is not released yet.

    Thanks,

    Matt

    Hi Matt,

    Customer would like to learn more about how to configure MCT8316Z using spi. Does he have to program to use it? Is it configurable to send 16-bit data directly? If he wants to read the status of a register, what data need to be sent?

    Thanks,

    Annie

    Hi Annie,

    We did not release an MCT8316Z SPI part - the PMCT8316Z0TRGFR does not have a SPI interface.

    We will release a different device orderable in the MCT8316Z family which has a SPI interface.

    Thanks,

    Matt

    Hi Matt,

    Thanks for your response,

    PMCT8316Z0TRGFR has no spi interface, can it be used directly without configuration?

    Thanks,

    Annie

    Hi Annie,

    The MCT8316Z0T device can be configured using hardware pins by placing a resistor on these pins. MCT8316Z0T does not have any SPI configuration.

    • MODE - PWM control mode setting
    • SLEW - Slew rate setting
    • ILIMIT - Current limit configuration
    • ADVANCE - Lead angle setting
    • VSEL_BK - Buck output voltage configuration
    • MODE - Active demagnetization configuration

    Thanks,

    Matt
