SMDB3 Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for SMDB3 is -40°C to 125°C.

  • The SMDB3 can be configured for I2C or SPI interface by setting the MODE pin accordingly. For I2C, connect MODE to VCC, and for SPI, connect MODE to GND.

  • The maximum frequency for the SMDB3's I2C interface is 400 kHz.

  • The SMDB3 has an internal POR and BOR circuitry. The POR is triggered when the power supply voltage (VDD) falls below 1.5V, and the BOR is triggered when VDD falls below 2.2V. Ensure that your system design takes these reset mechanisms into account.

  • The WAKEUP pin is used to wake up the device from standby mode. It can be connected to an external interrupt source or a push-button to wake up the device.
