Pin Description

1

Power supply pin.

2

STBY

Standby pin. This pin has an internal pull-down resistor (100k

Ω (typ.)). In the case of open

≤10μA (Standby mode)

3,4,5

GND

Ground pin.

6,7

OUT

Output pin. When a load short-circuit causes an overcurrent (6A min) to flow into a device,

output current is limited in order to protect the IC.

8

N.C

No-Connect pin. (not connected to the chip.)

9

IN

Input pin. The IN pin has an internal pull-down resistor (100k

Ω (typ.)).

Even if the IN pin is open, the output will not accidentally turn on.

10

DIAG

Self-diagnosis output pin. N-channel open drain.
