Instructions for PA9544A
Power Supply Connection:
- Connect the VDD pin to a power supply within the operating voltage range of 2.7V to 5.5V.
- Ensure the GND pin is connected to a common ground.
I2C Communication Setup:
- Connect the SDA and SCL pins to the corresponding lines of your I2C bus.
- Ensure pull-up resistors are used on both SDA and SCL lines to VDD, typically in the range of 1.8kΩ to 10kΩ depending on bus length and speed.
Channel Configuration:
- Use I2C commands to configure the direction (input/output) of each channel.
- Set the state (high/low) of output channels via I2C commands.
Operating Environment:
- Operate the device within the temperature range of -40°C to +85°C for reliable performance.
- Store the device between -65°C and +150°C when not in use.
Handling Static Electricity:
- Handle with care to avoid damage from static electricity; use appropriate ESD protection measures.
Refer to Datasheet:
- For detailed timing diagrams, specific command sequences, and advanced configurations, refer to the full datasheet provided by the manufacturer.
