Signal Characteristics (Cont.)  
Specifications apply over all line, load conditions, unless otherwise noted; Boldface specifications apply over the temperature range of -40°C TINTERNAL  
125°C (T-Grade); All other specifications are at TINTERNAL = 25ºC unless otherwise noted.  
Auxiliary Voltage Source  
• The VAUX pin is a standard analog I/O configured as an output from an internal µC.  
• VAUX is internally connected to µC output as internally pulled high to a 3.3 V regulator with 2% tolerance, a 1% resistor of 1.5 kΩ.  
• VAUX can be used as a "Ready to process full power" flag. This pin transitions VAUX voltage after a 2 ms delay from the start of powertrain activating,  
signaling the end of softstart.  
• VAUX can be used as "Fault flag". This pin is pulled low internally when a fault protection is detected.
