Fault-Detection Output. FAULT goes low during current limit, undervoltage lockout, or thermal
limit. FAULT is an open-drain output that requires an external pull-up resistor.
VY Supply Voltage Inputs. VY pins must be connected to one another. Input range is +3V to +5.5V.
VY is normally connected to 3.3V.
Three-Level Code-Select Input. See Logic Truth Tables .
Channel A VCC Control Input. See Logic Truth Tables.
Channel A VCC Control Input. See Logic Truth Tables.
Logic Supply-Voltage Input. Connect to the +3.3V or +5V host system supply. VL can be supplied
via the output of a CMOS-logic gate to produce an overriding shutdown. When used as a
shutdown input, VL should have a 1kΩ series resistor with a 0.1µF capacitor to ground (Figure 2).
Note that VL must be greater than undervoltage lockout for any switches to be turned on.
Low = Standard “Intel” code
High = “Cirrus” code
