+12V Supply Voltage Input
VPP Output
VCC Output. Connect all four VCC pins together.
VX Supply Voltage Input. Input range is +3.0V to +5.5V. VX is normally connected to 5V.
VY and Logic Supply Voltage Inputs. VY pins must be connected together. Input range is +3V to
+5.5V. VY is normally connected to 3.3V.
VPP Control Input (see Logic Truth Tables).
VPP Control Input (see Logic Truth Tables).
VCC Control Input (see Logic Truth Tables).
VCC Control Input (see Logic Truth Tables).
Three-Level Code-Select Input (see Logic Truth Tables): Low = Standard “Intel” code,
High = “Cirrus” code, Mid-Supply = “Databook” code (Figure 4).
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.
