TECHNICAL DATA
PWM Power Control IC
with Interference Suppression
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
