Microchip Technology's MCP130T-300 Supervisory Circuit

The MCP130T-300 is a highly reliable voltage supervisory device designed by Microchip Technology, tailored to maintain system integrity by monitoring the supply voltage level. This precision voltage detector is an essential component for applications that require an effective power-on reset control or a low-voltage monitoring system.

Key Features

• Voltage Threshold: The device has a preset trigger threshold voltage of 3.00V, which is ideal for systems operating around this voltage level, ensuring that the device will assert a reset signal whenever the monitored voltage drops below this precise value.
• Reset Timeout: It offers a significant 350 ms (minimum) reset timeout period, which provides ample time for the power supply to stabilize before allowing the processor to resume operation.
• Operating Voltage Range: The MCP130T-300 operates over a wide voltage range from 1.0V to 5.5V, making it versatile for various low voltage applications.
• Low Supply Current: With a low supply current of 5 µA (typical), the device is an excellent choice for power-sensitive applications.
• Temperature Stability: The built-in temperature compensation ensures reliable operation over the temperature range of -40°C to +125°C.
• Output Configuration: It provides an active-low, open-drain reset output, which is compatible with most microcontrollers and can be easily interfaced with other digital systems.
• Packaging: This supervisory circuit is available in a 3-pin TO-92 package, which is suitable for through-hole mounting, facilitating easy integration into a wide array of designs.

Applications

The MCP130T-300 is particularly suitable for applications that require a robust and reliable system reset function. It is commonly used in:

• Microcontroller systems
• Portable/battery-powered equipment
