PRODUCTION DATA
This design shows two shunt voltage conversion times in order to demonstrate the difference in the alert response times. This design generates a critical-alert response when the input voltage exceeds 80 mV on channel 1. See Table 9-1 for all design parameters.
For the first example the shunt voltage conversion time is set to 1.1 ms. When the input signal exceeds 80 mV, the Critical alert pin pulls low after the conversion cycle completes, indicating an overcurrent condition, as shown in Figure 9-2.
For the second example, the conversion time is set to 588 µs, and the response is shown in Figure 9-3.
