Description
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.
TTL compatible input. A HIGH input signal turns the output transistor off and a LOW
input turns it on. If the input is left open it will be detected as high level.
Ground supply.
Supply voltage. Nominally 5 V to 40 V.
Output pin. Current flows out from this pin through the load to GND. Nominal current is 8 mA
to 2 A.
