PCA9539PWJ Frequently Asked Questions (FAQs)

  • The PCA9539PWJ can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The PCA9539PWJ has an internal POR circuit that resets the device when the supply voltage (VCC) is powered on. To handle POR, ensure that the I2C bus is idle during power-on and wait for at least 1 ms after power-on before sending commands to the device.
  • Each GPIO pin of the PCA9539PWJ can sink or source up to 25 mA of current. However, the total current sunk or sourced by all GPIO pins should not exceed 100 mA.
  • The PCA9539PWJ can be configured for open-drain or push-pull output mode by writing to the Output Mode Register (OMR). Setting OMR to 0x00 configures the device for open-drain mode, while setting OMR to 0x01 configures it for push-pull mode.
  • The internal pull-up resistors on the PCA9539PWJ are used to pull up the GPIO pins to VCC when they are configured as inputs. This helps to prevent floating inputs and ensures that the pins are in a defined state.
