Touch Sensor Controller
Typical Application Circuit
Notes:
• The voltage range of VDD can be from 2.3V to 5.5V. If internal LDO is used, it should be from 3V to 5.5V.
• Pull-Up resistors are required for I
• Each tuning capacitor is an optional component depending on PCB layout environment.
• The circuit above is a typical application circuit using an internal LDO.
• RESET_N pin should be connected to host MCU GPIO and needs an RC filter. (R1=10KΩ, C1=1uF)
• For LED control through DIO ports, sink current circuit is mandatory as shown above.
