TPS274C65: SPI baudrate for 12ch control

David Huang

Part Number: TPS274C65

Hi Team,

What would be the approximate SPI baudrate requirement for controlling/short detection/current measurement 12ch with 0.5ms per cycle?

My customer is evaluating with EVM and trying to match the SPI baudrate requirement with their devices.

David,

The maximum baud rate for the device is 10Mhz. Generally, you just max out your baud rate of these devices to get the fastest speed possible as allowed by your microcontroller.

You can find an "application complete" version EVM here:

This EVM has a GUI, open source code, and two TPS274C65 devices in "addressable SPI" implementation. You can find the user's guide here that provides some implementation insights:
