iC-DN

LOWSIDE SWITCH

Rev C1, Page 2/10

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-cir-

cuiting 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 maximum

permissive voltage difference between NI and VN is

36 V.
