FEATURES
APPLICATIONS
♦ 36 V highside switch/level shifter
♦ p-channel output driver without charge pump for short
activation time
♦ Decoupling of input and output reference voltages (SOT23-6L)
permits control by 5V logic
♦ Highside switch for industrial
applications, such as relays,
inductive proximity sensors and
light barriers
♦ 200 mA of output current
♦ Short-circuit protected
♦ Output with an active freewheeling circuit
♦ On-chip overtemperature protection with hysteresis
♦ 4 to 36 V input voltage range
♦ Input with hysteresis
♦ 3-pin configuration possible
PACKAGES
♦ Wide temperature range of -40 to 120 °C
♦ Package option: (SOT223-4L, SC59-3L, DFN, CSP)

DESCRIPTION
iC-DP is a monolithic highside switch for ohmic, in- the input voltage threshold V(PI)-V(NI) of typically
ductive and capacitive loads. 3.5 V is exceeded.
Designed for a wide input voltage range of 4 to 36 V, When used as a 4-pin element (with the SOT23-6L
it is capable of supplying a minimum output current package only), the input (PI, NI) and output (DP, VP)
of 200 mA. The output acts as a current source with reference voltages are decoupled. The maximum

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.
