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