PCA9632TK,118 datasheet by NXP Semiconductors

PCA9632TK,118 Frequently Asked Questions (FAQs)

• What is the maximum current that the PCA9632TK,118 can sink or source?
  The PCA9632TK,118 can sink or source up to 25mA per output pin, and up to 100mA total for all outputs combined.
• How do I configure the PCA9632TK,118 for I2C or SMBus interface?
  The PCA9632TK,118 can be configured for I2C or SMBus interface by setting the SCL pin high or low, respectively, during power-up. The device will then operate in the selected interface mode.
• What is the purpose of the reset pin (RST) on the PCA9632TK,118?
  The reset pin (RST) is an active-low input that resets the PCA9632TK,118 to its default state. When the RST pin is pulled low, the device resets and all outputs are set to a high-impedance state.
• How do I program the PCA9632TK,118 to operate in 8-bit or 16-bit PWM mode?
  The PCA9632TK,118 can be programmed to operate in 8-bit or 16-bit PWM mode by writing to the MODE register. Setting the MODE register to 0x00 enables 8-bit PWM mode, while setting it to 0x01 enables 16-bit PWM mode.
• What is the maximum frequency of the PCA9632TK,118's internal oscillator?
  The maximum frequency of the PCA9632TK,118's internal oscillator is 256 kHz.
