8.2.1 Simplified Application Schematic

Figure 8-1 shows the simplified schematic where RSETA and RSETB are used to set channel A trip point (SETA) and channel B trip point and hysteresis for both channels (SETB). SETA and SETB can be programmed at a variety of temperatures based on the device, as described in Table 7-1 for channel A trip point, and Table 7-2 for channel B trip point and hysteresis for both channels. OUTA and OUTB outputs correspond to the temperature threshold detection at SETA and SETB, respectively.
