Input pins used to control output. H : output on
(See Table 1, Truth Table.)
Ground pins for Logic portion.
Self-diagnosis output pins (See Table 2, Truth Table & Timing Chart.)NPN transistor
open-collector output. When output becomes overcurrent, set to on; duty 97% on (low). At
normal operation, set to open (high).
DG1 : OR output of OUT1 & OUT2
DG2 : OR output of OUT3 & OUT4
Connected to load, with sink 0.5A. Features overcurrent detection function to protect IC from
instantaneous destruction at load short (See section on Multiple Protections below.) Features
diodes for absorbing counter electromotive force built into both VCC and GND sides.
Ground pins for output portion.
Power supply pins. When more than 30V is applied, overvoltage protection function turns off
output to protect the IC and motor load.
Not connected. (Electrically, this pin is completely open.)
