O P
The external overcurrent adjust and the thermal shutdown are commoned
at the PWM/l
O
ADJ pin and tieing it to V
CC
will disable the thermal shut-
down. PWM current/speed control can be performed at the PWM/l
O
ADJ pin
from a standard totem-pole logic output with a series Schottky diode
(1N5818,1N5819, or equivalent) or by pulling it low through an open-
collector transistor (no pull-up resistor). PWM/l
O
ADJ input voltages greater
than 0.3 V are not recommended and may create an unstable operating
condition.
