The Low Side Driver drain pin for the TURN LED array
The Low Side Driver source pin, used to detect either a lamp outage or an
over-current condition for the TURN LED array
The Low Side Driver drain pin for the STOP LED array
The Low Side Driver source pin, used to detect either a lamp outage or an
over-current condition for the STOP LED array
The Low Side Driver drain pin for the TAIL LED array
The Low Side Driver source pin, used to detect either a lamp outage or an
over-current condition for the TAIL LED array
Determines, according to a percentange of VREF, the Pulse Width Controller
internal oscillator duty cycle

Power Supply
TAIL input pin. When brought high, TAIL activates the IC and drives the TAIL led
array.
STOP input pin. When brought high, STOP activates the IC and drives the
STOP led array.
TURN input pin. When brought high, TURN activates the IC and drives the
TURN led array.
Internal Error Amplifier Inverting Pin
Power MOSFET drain pin
A Three State Input. It determine the control logic for TAIL and STOP Low Side
Drivers.
A weak pulled up signal during lamps No Fault condition and an active pulldown
when a Fault condition is detected.
