PCA9629PW,118 datasheet by NXP Semiconductors

PCA9629PW,118 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that the PCA9629PW,118 can support?
  The PCA9629PW,118 can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
• How do I configure the PCA9629PW,118 for 8-bit or 16-bit PWM operation?
  The PCA9629PW,118 can be configured for 8-bit or 16-bit PWM operation by setting the PWM resolution bits (PWMRES) in the Control Register (CTR). For 8-bit PWM, set PWMRES to 0, and for 16-bit PWM, set PWMRES to 1.
• What is the minimum and maximum value of the output current that the PCA9629PW,118 can sink or source?
  The PCA9629PW,118 can sink or source output currents between 0.5 mA and 50 mA per channel, depending on the external resistor value and the supply voltage.
• How do I implement fault detection and protection using the PCA9629PW,118?
  The PCA9629PW,118 has built-in fault detection and protection features, including overcurrent detection, short-circuit detection, and thermal shutdown. These features can be enabled and configured using the Fault Detection and Protection Register (FDP).
• Can the PCA9629PW,118 be used in a daisy-chain configuration?
  Yes, the PCA9629PW,118 can be used in a daisy-chain configuration, allowing multiple devices to be connected in series and controlled using a single I2C bus.
