DESCRIPTION
iC-DN is a monolithic lowside switch for ohmic, induc- excessive temperature. The chip is activated when
tive and capacitive loads.
the input voltage threshold V(PI)-V(NI) of typically
3.5 V is exceeded.
Designed for a wide input voltage range of 4 to 36 V, it
is capable of supplying a minimum output current of With four leads, the input (PI, NI) and output (DN,
200 mA. The output acts as a current source with VN) reference voltages are decoupled. The maxi-
a low saturation voltage; protection against short- mum permissive voltage difference between NI and
circuiting is provided by the device shutting down with VN is 36 V.

ABSOLUTE MAXIMUM RATINGS
Beyond these values damage may occur; device operation is not guaranteed. Absolute Maximum Ratings are no Operating Conditions.
Integrated circuits with system interfaces, e.g. via cable accessible pins (I/O pins, line drivers) are per principle endangered by injected
interferences, which may compromise the function or durability. The robustness of the devices has to be verified by the user during system
development with regards to applying standards and ensured where necessary by additional protective circuitry. By the manufacturer
suggested protective circuitry is for information only and given without responsibility and has to be verified within the actual system with
respect to actual interferences.
