Pin Descriptions

Pin

Symbol

Function

1

IN

Input terminal. The pull-down resistor is internally connected.

2

GND

Earth terminal.

3, 4

OUT

Output terminal. When the load becomes in a short-circuit state and if the current

exceeds overcurrent detection value of 0.8A (Min) the current flowing in the

output pin will be limited due IC protection.

5, 6

Power-supply terminal.

7

N.C

N.C

8

ST

Self-diagnostic output terminal. "L" is becomes the output state during overcurrent,

overheating and open load detection conditions.

Please refer to Diagnostic Output Truth Table on page 5. The circuit is composed of

an open drain N channel MOS.

TAB

Since it has connected with sub of IC, please connect the heat dissipation metal to

external GND potential. (HTSOP-J8,HSON8)

(1)MSOP8 does not have Cooling Tab.
