HIGHSIDE SWITCH

DESCRIPTION

Rev C3, Page 2/8

iC-DP is a monolithic highside switch for ohmic, in­ductive and capacitive loads.

Designed for a wide input voltage range of 4 to 36V,
it is capable of supplying a minimum output current
of 200mA. The output acts as a current source with
a low saturation voltage; protection against short­circuiting is provided by the deviceshutting down with

PIN CONFIGURATION

excessive temperature. The chip is activated when
the input voltage threshold V(PI)-V(NI) of typically

3.5V is exceeded.
When used as a 4-pin element, the input (PI, NI)

and output (DP, VP) reference voltages are decou­pled. The maximum permissive voltage difference
between VP and PI 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.
