PWM Power Control with Automatic Duty Cycle Reduction
Description
The U6084B is a bipolar technology PWM-IC designed
for the control of an N-channel power MOSFET used as
a high-side switch. The IC is ideal for use in the brightness
control (dimming) of lamps such as, in dashboard
applications. For a constant brightness the preselected
duty cycle can be reduced automatically as a function of
the supply voltage.
Features
D Pulse width modulation up to 2 kHz clock frequency
D Protection against short circuit, load-dump
overvoltage and reverse VS
D Duty cycle 0 to 100 % continuously
D Output stage for power MOSFET
D Interference and damage protection according to
VDE 0839 and ISO/TR 7637/1.
D Charge pump noise suppressed
D Ground wire breakage protection
