CODE
25
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 1k
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.
VL
28
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.
VY

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.
