For devices that have multiple SEL pins such as the TPS1HA08, the device is able to be configured in three ways: device temperature, load current, or supply voltage. As with the single SEL pin devices, device temperature allows for measuring the internal junction temperature and the load current measurement allows for a proportionate voltage signal that reflects the load current. An additional setting allows for monitoring the supply voltage that is supplying power to the output, which is helpful in applications where a battery is involved such as in the automotive industry. For devices with multiple channels, additional SEL pins are used to select which channel to monitor.

Table 2-4 shows the different diagnostics that are used in the SELx pins on the TPS1HA08-Q1 and how to configure them. Table 2-5 shows the configurations that available on the SELx pins on the TPS2HB16 and the settings associated with them.
