PCA9624PW,112 datasheet by NXP Semiconductors

PCA9624PW,112 Frequently Asked Questions (FAQs)

• What is the maximum current that the PCA9624PW,112 can sink or source?
  The PCA9624PW,112 can sink or source up to 25mA per output pin, and up to 100mA total current for all outputs combined.
• How do I configure the PCA9624PW,112 for I2C or SMBus interface?
  The PCA9624PW,112 can be configured for I2C or SMBus interface by setting the SCL pin high or low, respectively, during power-up. For I2C, SCL should be high, and for SMBus, SCL should be low.
• What is the purpose of the reset pin (RST) on the PCA9624PW,112?
  The reset pin (RST) is an active-low input that resets the PCA9624PW,112 to its default state. It can be used to recover from a fault condition or to initialize the device during power-up.
• Can the PCA9624PW,112 be used in a hot-swappable application?
  Yes, the PCA9624PW,112 is designed to be hot-swappable, meaning it can be inserted or removed from a system without powering down the system.
• What is the maximum clock frequency supported by the PCA9624PW,112?
  The PCA9624PW,112 supports clock frequencies up to 400 kHz for I2C and 100 kHz for SMBus.
