U6083B
PWM Power Control with Interference Suppression
Description
The U6083B 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 use in the brightness con-
trol (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
over–voltage and reverse VS
D Duty cycle 18 to 100% continuously
D Internally reduced pulse slope of lamp’s voltage
D Interference and damage protection according to
VDE 0839 and ISO/TR 7637/1.
D Charge pump noise suppressed
D Ground wire breakage protection
