U6084B-MFPG3Y
U6084B-MFPG3Y Datasheet
The U6084B is a PWM-IC with bipolar technology 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 constant brightness, the preselected duty cycle can be reduced automatically as a function of the supply voltage.
