PWM Power Control with Interference Suppression
KKA6083 is a PWM IC in bipolar technology for thecontrol 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.
·Pulse width modulation up to 2 kHz clock frequency
·Protection against short circuit, load dump
over–voltage and reverse VS
·Duty cycle 15 to 100% continuously
·Reduced internal pulse slope of lamp’s voltage
·High side switch
·Interference and damage protection according to VDE 0839 and ISO/TR 7637/1.
·Charge pump noise suppressed
·Ground wire breakage protection
·Low interference voltage
Case: DIP 8
