7.4 Device Functional Modes

The digital interface, including the open-drain DIAG pin are functional as soon as VDD rises above the VDDPOR threshold. Analog functions, including the circuitry on the high-side, are enabled as soon as VDD rises above the analog under voltage lockout threshold VDDUV .

At power-down, analog functions are disabled as VDD falls below the VDDUV (falling) voltage level. The digital interface, including the open-drain DIAG pin remain functional until VDD drops below the VDDPOR (falling) voltage level. Figure 7-8 shows the different enable thresholds for the AMC3336.

GUID-20210325-CA0I-K2HK-HK9R-SW6V9DS4D2HT-low.svg Figure 7-8 AMC3336 Enable Thresholds

Below the VDDPOR voltage level the digital output pins are not actively driven, that is they are in a high-impedance state but clamped to one diode-voltage above the VDD supply.
