PRODUCTION DATA.
The FLTB pin is the open-drain fault output. FLTB sinks current when the MOSFET should be enabled, but either there is no GATE voltage, V(AC) is greater than 0.4 V with GATE driven ON, the internal UVLO is not satisfied. FLTB has a 3-ms deglitch filter on the falling edge to prevent transients from creating false signals. FLTB may not be valid at voltages below the internal VDD UVLO.
