Description
The ELM413 is both an LED controller and a circuit startup timer in an 8 pin package. The high current capabilities of its outputs allow most LEDs to be directly driven, usually only requiring a single current limiting resistor.

Features
• Low power CMOS design - typically 1mA at 5V
• Operates over a supply range of 3.0 to 5.5 volts
• Schmitt trigger controlled operation
• Requires no external timing components
• Warmup periods from 0.1 to 5 seconds
• Auxiliary output active after warmup period
• High current drive outputs - up to 25 mA

Applications
• Pilot ‘lamp’ circuits
• Sequentially enabled systems
• Delay on operate circuits
• Audio amplifier power managers
• Monostable (one-shot) circuits
