PCAL6524HEHP Frequently Asked Questions (FAQs)

  • The maximum current rating for each GPIO pin is 2mA, as specified in the datasheet. However, it's recommended to limit the current to 1mA to ensure reliable operation.
  • The PCAL6524HEHP can be configured for I2C or SMBus interface by setting the appropriate values in the Control Register (CR) and the Configuration Register (CFGR). Refer to the datasheet for specific register settings.
  • The maximum frequency for the I2C interface is 400 kHz, as specified in the datasheet. However, the actual frequency may be limited by the system design and the capacitive load on the bus.
  • Interrupts generated by the PCAL6524HEHP can be handled by configuring the Interrupt Enable Register (IER) and the Interrupt Status Register (ISR). The interrupt service routine should clear the interrupt flag and perform the necessary actions.
  • The power-on reset (POR) timing for the PCAL6524HEHP is typically around 1ms, but can vary depending on the system design and power supply characteristics.
