The ILC5061AM-28 is a voltage supervisor IC manufactured by Impala Linear Corporation. It's designed to monitor the voltage level of a power supply and generate a reset signal when the voltage drops below a specified threshold. This ensures that microcontrollers or other digital circuits are reset properly during power-up or brown-out conditions, preventing erratic behavior.

Applications

• Microcontroller Systems: Provides a reset signal to the microcontroller during power-up or brown-out conditions.
• Embedded Systems: Monitors the power supply voltage in embedded applications.
• Industrial Control: Monitors critical voltage rails in industrial equipment.
• Automotive Electronics: Used in automotive systems to ensure reliable operation during voltage fluctuations.

Features

• Precision Voltage Monitoring: Accurately monitors the input voltage.
• Open-Drain Reset Output: Provides a reset signal through an open-drain output, requiring a pull-up resistor.
• Low Supply Current: Minimizes power consumption.
• Fixed Threshold Voltage: Features a fixed threshold voltage of typically 2.8V (as indicated by '-28' in the part number).

Benefits

• Improved System Reliability: Prevents system malfunctions due to voltage drops.
• Guaranteed Proper Startup: Ensures that the system starts up in a known and stable state.
• Data Protection: Helps protect against data corruption during voltage fluctuations.
• Simplified Design: Requires minimal external components for operation.

Additional Details

The ILC5061AM-28 is commonly available in small surface-mount packages such as SOT-23. A key parameter is the reset timeout period, which determines how long the reset signal is asserted after the voltage recovers. It’s crucial to select an appropriate pull-up resistor value for the reset output. Consult the datasheet for details on the operating voltage range, reset threshold accuracy, and reset timeout period. Ensure that the pull-up resistor is properly sized to drive the load connected to the reset output. Always refer to the manufacturer's datasheet for detailed specifications and application recommendations.
