8.4.1 Fail-Safe Output
In the case of a missing high-side supply voltage (LDOIN), the output of a ΔΣ modulator is not defined and can cause a system malfunction. In systems with high safety requirements, this behavior is not acceptable. Therefore, the AMC1304 implements a fail-safe output function that ensures the device maintains its output level in case of a missing LDOIN, as shown in Figure 51.
