STR2550 Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the STR2550 is 4.5V to 5.5V, with a typical voltage of 5V.

  • To ensure reliable communication, use a pull-up resistor on the SDA line, and ensure the microcontroller's clock frequency is within the STR2550's specified range (100 kHz to 400 kHz).

  • The maximum current rating for the STR2550's output pins is 20mA per pin, with a total current limit of 100mA for all output pins combined.

  • Yes, the STR2550 can be used with a 3.3V microcontroller, but you'll need to use a level shifter or voltage translator to ensure compatible voltage levels.

  • Implement error detection and retry mechanisms in your firmware to handle I2C bus errors, such as clock stretching, arbitration, and data corruption.
