PCA9634PW,112 Frequently Asked Questions (FAQs)

  • The PCA9634PW,112 can source up to 25mA and sink up to 50mA per output, making it suitable for driving LEDs, relays, and other loads.
  • To ensure a proper reset, the RESET pin should be pulled high for at least 1ms after power-up. This can be done using an external pull-up resistor and capacitor.
  • Yes, the PCA9634PW,112 can drive inductive loads like relays, but it's essential to add a flyback diode to protect the device from back-EMF. Additionally, the relay's coil voltage and current should be within the device's output specifications.
  • The output mode can be configured using the OPMODE register (register 0x01). Setting the OPMODE bit to 0 enables open-drain mode, while setting it to 1 enables push-pull mode.
  • The recommended clock frequency for the I2C interface is up to 400 kHz. However, the device can operate at higher frequencies, but with reduced noise immunity and increased power consumption.
