U6084B - PWM Power Control with Automatic Duty-cycle Reduction

General Description

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.

Key Features

  • Pulse-width Modulation up to 2 kHz Clock Frequency Protection against Short-circuit, Load-dump Overvoltage and Reverse VS Duty-cycle 0 to 100% Continuously Output Stage for Power MOSFET Interference and Damage Protection According to VDE 0839 and ISO/TR 7637/1 Charge-pump Noise Suppressed Ground-wire Breakage Protection.

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. Figure 1.
