TECHNICAL DATA

PWM Power Control IC

with Interference Suppression

IL6083

Description

The designed IC is based on bipolar technology for the

control of an N-channel power MOSFET used as a high-side

switch. The IC is ideal for use in brightness control systems

(dimming) of lamps, for example, in dashboard applications.

Features

• Protection Against Short-circuit, Load Dump Overvoltage

and Reverse VS

• Duty Cycle 18 to 100% Continuously

• Internally Reduced Pulse Slope of Lamp's Voltage

• Interference and Damage Protection

• Charge-pump Noise Suppression

• Ground-wire Breakage Protection
