PCA9555PWRG4 Frequently Asked Questions (FAQs)

  • The PCA9555PWRG4 can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The PCA9555PWRG4 has three power modes: Normal, Partial Power-Down, and Full Power-Down. These modes can be configured by writing to the Power-Down Control register (0x06) and the Configuration register (0x03). Refer to the datasheet for specific bit settings.
  • The PCA9555PWRG4 can sink or source up to 25 mA of current on each GPIO pin, but the total current should not exceed 100 mA for the entire device.
  • The PCA9555PWRG4 can be reset to its default state by pulling the RESET pin low for at least 1 ms. This will reset all registers to their default values.
  • Yes, the PCA9555PWRG4 can be used as a level translator between 3.3V and 5V systems. The device can operate with a VCC supply voltage of 2.3V to 5.5V, and the GPIO pins can tolerate input voltages up to 5.5V.
