8.3 System Examples

The LMT01 device can be configured in a number of ways. Transistor level shifting can be used so that the output pulse of the device can be read with a GPIO (see Figure 32). An isolation block can be inserted to achieve electrical isolation (see Figure 33). Multiple LMT01 devices can be controlled with GPIOs enabling temperature monitor for multiple zones. Lastly, the LMT01 device can be configured to have a common ground with a high side signal (see Figure 35).

Note: to turn off an LMT01 set the GPIO pin connected to VP to high impedance state as setting it low would cause the off LMT01 to be reverse biased. Comparator input of MCU must be used.

Note: the VN of the LMT01 must be connected to the MCU GND.
