MAX32664A shutdown current consumption issue

Category: Hardware
Product Number: MAX32664

We are currently experiencing an issue with the MAX32664GTGA+T sensor hub on our custom board. Despite configuring the hub to disable algorithm, disable MAX30101 sensor and go into shutdown mode, we observe a current consumption of 7.6 mA.

Hardware:

  • MAX32664GTGA+T Sensor Hub, firmware version 1.9.1
  • MAX30101 SpO2 Sensor
  • No accelerometer (KX122 or external) is being used.

Thank you
