TDA4VH-Q1: Some questions about TDA4VH-Q1

Genius 13655 points
Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH

Hello Champs,

Customer has some questions about TDA4VH-Q1

1. Demo schematic diagram VSYS_3V3 is to power the SOC minimum system, the current output capacity is 30A (15A + 15A) At present, in the case of compatibility with the use requirements of TDA4VH, whether the current here can be designed at 3.3V/20A, the precondition: only consider the power consumption of the SOC, and the next buck considers more than 95% efficency

2. When one of MCU power supply fails, does it affect the whole SOC?

3. When loading code or ISP debugging, must it use USB3.0?

4. When not using WKUP_UART as streaming control?

5. Can EHRPWM output PWM? Can it be used for USS driver? Can Detimer output PWM?

6. Which is the dedicated pin for FSYNC? Can't find related pins on Demo board. 

7. Is there power consumption for DDR Retention, IO Retention?

8.  MCU and Main is isolated in hardware, it is difficulty to realize MCU-ONLY in software, will it affect the static power consumption?

Thanks
Regards

  • 1.  Customer would need to complete a TDA4VH-Q1 power estimation based on their use case (as power requirements can vary greatly based on usage).  From that power estimation, the customer can then design the supplies to generate that needed power.  Note the EVM is design for maximum power usage for the TDA4VH-Q1 to cover all use cases.

    2.  The MCU cannot operate if any of its supplies fail, and the MCU is the 'master' of the entire TDA4VH device.

    3.  USB is an optional interface for loading code.  Several other interfaces are available on the processor include SD Card, Ethernet, USB2.0, UART, JTAG, and more.

    4. Unclear on question - please re-state.

    5.  Yes EHRPWM can output PWM signals.  Please refer to the Technical Reference Manual (TRM) for full description of EHRPWM module.

    6.  Yes FSYNC is supported.  Please refer to the Data Manual (DM) for pin locations

    7.  Are you asking what is the expect power of device when operating in DDR retention and/or IO retention?  I'll need to see if this is available.

    8. MCU-Only mode provides ability to power OFF the main domain, so yes it will affect static power consumption.
