PGA460-Q1: TIDA-01597 reference design power consumption

Part Number: PGA460-Q1
Other Parts Discussed in Thread: TIDA-01597, PGA460,

I'm working with a customer who I'm assisting on the TDA4V Mid processor portion.  However, they asked me about the typical and maximum power consumption of the module documented in the TIDA-01597 reference design.   They noted that the documentation currently shows 6W each@ 12V peak.  Is this correct?

    Hi John,

    Is the power question in regard to the PGA460 or the TDA4V?

    The TIDA-01597 uses the PGA460-Q1 Ultrasonic Sensor Driver and Signal Conditioner, typically used for automotive park assist applications. A single PGA460-Q1 device operates at a voltage between 6-28V, and draws 12mA of current. Thus, power consumption per ultrasonic sensor module can range between 72mW to 336mW depending on the supply voltage.

    The PGA460-Q1 EVM GUI software includes a Power Budget Calculator, which can also factor in additional power saving device features such as low-power mode or the ability to load switch power to/from the device.

    For details on a single sensor module of the PGA460-Q1, see the http://www.ti.com/tool/PGA460PSM-EVM or http://www.ti.com/tool/TIDA-060024.

    Akeem,
    Thanks for the quick response.  I'm pretty sure that this has only to do with the PGA460-Q1 as we have a separate exercise involving the loading on the TDA4V.  I'll relay this information. Thanks again,

    John
