MCP41HV31T-103E/ST Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VSS, and then the logic inputs. This ensures proper device operation and prevents potential latch-up conditions.
  • To retain the wiper position during power-down, the CS pin should be held high and the SCK and SDI pins should be held low. This ensures that the device remains in a static state and the wiper position is preserved.
  • The maximum frequency of the serial clock (SCK) input is 3.6 MHz. Exceeding this frequency may result in incorrect device operation or data corruption.
  • Yes, the MCP41HV31T-103E/ST can be used in a ratiometric application, but it's essential to ensure that the voltage applied to the RH and RL pins is proportional to the supply voltage (VDD). This ensures that the device operates within its specified range and maintains its accuracy.
  • During a power-down or brownout condition, the device will reset, and the wiper position will be lost. To handle this, it's recommended to use an external power supervisor or reset circuit to detect the power-down condition and reset the device accordingly.
