Product label The very low R ( 25m up to T = 125C) makes the IC suitable for the DS-ON J applications with up to 2.4A/ 5.6A steady state operating current. The output channel is protected against junction over-temperature events by a junction temperature sensor, and a further temperature sensor is included to monitor case temperature, so the overheated output channel can only be turned back ON when the case temperature returns below the reset temperature. The embedded overload protection circuit monitors the output current and, on triggering of the activation threshold (I ), starts modulating the impedance of the PK output switch to limit the output current to I , for both IC and load protection. LIM The IC offers two different sets of activation threshold and limitation levels (I , PKH I and I , I ) for smart driving of capacitive loads (such as bulb lamps) and LIMH PKL LIML loads with initial peak current requirements. The IC diagnostics is based on FLT and FLT pins (both current source) activated 1 2 by respective overload or overtemperature events on the output channel.
