PCA9702PW,118 datasheet by NXP Semiconductors

PCA9702PW,118 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for PCA9702PW,118?
  The recommended operating voltage range for PCA9702PW,118 is 2.3V to 5.5V.
• How do I ensure reliable communication between the PCA9702PW,118 and other I2C devices?
  To ensure reliable communication, make sure to use pull-up resistors on the SCL and SDA lines, and ensure that the clock frequency is within the specified range (up to 400 kHz).
• What is the maximum current that the PCA9702PW,118 can sink or source?
  The PCA9702PW,118 can sink or source up to 20mA of current per pin.
• How do I handle bus contention on the I2C bus when using the PCA9702PW,118?
  To handle bus contention, use a bus arbiter or a multiplexer to ensure that only one device is driving the bus at a time. Additionally, use a bus buffer or repeater to improve signal integrity.
• What is the thermal resistance of the PCA9702PW,118 package?
  The thermal resistance of the PCA9702PW,118 package is typically around 150°C/W (junction-to-ambient).
