Description

1

Supply

Supply voltage. Nominally 5 V to 40 V.

2

Output

Output pin. Current flows from supply through the load into the pin. Nominal current is 8 mA to 2 A.

3

GND

Ground supply.

diode are bonded to a separate pin.

4

Error

Error indicating pin. Sinks current to ground if the protection and/or detection circuitry is activated.

Note: the current must be externally limited to 8 mA.

5

Input

TTL compatible input. A LOW input signal turns the output transistor off and a HIGH input turns it on.
