IL6083

Manufacturer Part Number
IL6083
Description
Pwm Power Control Ic With Interference Suppression
Manufacturer
IK Semicon Co., Ltd
Datasheet
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
• 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
