LINEAR INTEGRATED CIRCUIT
AUTOMOTIVE TOGGLE
SWITCH IC

DESCRIPTION
The bipolar integrated circuit UTC UU6032B is designed as a
toggle switch. The device, which has a defined power-on status,
can be used to control electrical loads, for example, fog lamps,
high/low beam or heated windows for automotive applications.
