TCAL9539PWR Frequently Asked Questions (FAQs)

  • The maximum current rating for each output of the TCAL9539PWR is 25mA. However, it's recommended to limit the current to 10mA per output to ensure reliable operation and prevent overheating.
  • The TCAL9539PWR can be configured for I2C or SMBus operation by setting the appropriate values on the ADDR pins (ADDR0-ADDR2). For I2C operation, set ADDR0-ADDR2 to 0, and for SMBus operation, set ADDR0-ADDR2 to 1. Refer to the datasheet for specific pin configurations.
  • The RESET pin is an active-low input that resets the device to its default state. To use it, connect the RESET pin to a logic low signal (typically through a pull-down resistor) for at least 1.5us to reset the device. This can be useful for initializing the device or recovering from a fault condition.
  • The TCAL9539PWR has built-in overcurrent protection for each output. If an output is short-circuited or overloaded, the device will limit the current to prevent damage. However, it's still recommended to add external current-limiting resistors or fuses to protect the device and surrounding circuitry.
  • The recommended operating temperature range for the TCAL9539PWR is -40°C to 85°C. However, the device can operate up to 125°C for short periods during soldering or other manufacturing processes.
