Pin Descriptions

Pin No.

Symbol

Function

1

IN

Input terminal; a pull down resistor is connected internally.

2

ST

Self-diagnostic output terminal; outputs “L” at detection of overcurrent, at open (IN=0V),

and in the overheat state. See the truth table. It is structured as COMS inverter output

circuit.

3,4

SOURCE

(GND)

Ground terminal

5,6

DRAIN

Output terminal; limits output current to protect IC when load is short-circuited and current

exceeding the overcurrent detection value (0.8A Min) flows to the output terminal.

7

N.C.

No Connect pin

8

VDD

Power supply terminal

Cooling Tab

(1)

TAB

The heat radiation metal on the substrate is connected to the IC sub. Therefore, connect

Cooling Tab to the external GND electrical potential (for HTSOP-J8 only).

(1)MSOP8 does not have Cooling Tab.
