8.2 Example Circuit - Conductive

Figure 8-2. MTCH9010 Example Circuit - Conductive Operation Mode

The schematic above presents an example circuit for the following scenario: Conductive Operation mode, Sleep configured for 256 seconds, System Lock disabled, and Extended Output mode disabled.

  • The OP_MODE pin is connected to GND, configuring the operation mode to Conductive
  • The SLP_PER pin is connected to VDD on a ten-level voltage divider, configuring the Sleep period to 256 seconds
  • The THR pin is connected to a potentiometer, where the Liquid Detection threshold is configured
  • The CFG_EN pin is connected to VDD, which disables the Enhanced Configuration mode.
  • The SYS_LK pin is connected to VDD, which disables the System Lock feature.
  • The UART_EN pin is connected to VDD, which disables the Extended Output mode.
