A good PCB layout for the TCST1103 involves keeping the input and output traces separate, using a ground plane, and minimizing the length of the traces to reduce noise and EMI.
To ensure proper biasing, connect the VCC pin to a stable voltage source, and the GND pin to a solid ground plane. Also, ensure that the input voltage is within the recommended range of 2.7V to 5.5V.
The TCST1103 can handle a maximum current of 100mA per channel, but it's recommended to keep the current below 50mA to ensure reliable operation and minimize power dissipation.
To protect the TCST1103 from ESD and overvoltage, use a TVS diode or a zener diode on the input lines, and consider adding a series resistor to limit the current in case of an overvoltage event.
The TCST1103 is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure that the device is properly heat-sinked and that the ambient temperature is within the recommended range.
