U6081B
PWM Power Control with Low Duty Cycle Switch Off
Description
U6081B is a PWM IC in bipolar technology for the
control of an N-channel power MOSFET used as a high
side switch. The IC is ideal for the use in the brightness
control (dimming) of lamps e.g., in dashboard
applications.
Features
D Pulse width modulation up to 2 kHz clock frequency
D Protection against short circuit, load dump overvol-
tage and reverse VS
D Duty cycle 0 to 100%
D Output stage for power MOSFET
D Interference and damage protection according to
VDE 0839 and ISO/TR 7637/1.
D Ground wire breakage protection
D Charge pump noise suppressed
