Microchip Technology's MCP102T-475E/TT Voltage Supervisor

The MCP102T-475E/TT is a highly reliable voltage supervisor component designed and manufactured by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This compact device is an essential element for a variety of applications that require precise voltage monitoring to ensure the stable operation of microcontrollers and other digital systems.

The MCP102T-475E/TT is engineered to maintain system integrity by monitoring the supply voltage and asserting a reset signal whenever the monitored voltage drops below a predefined threshold. The reset signal ensures that the microcontroller or processor restarts in a known state, which is crucial for applications that cannot tolerate any form of data corruption or unpredictable behavior.

Key Features:

• Voltage Threshold: The device has a preset trigger threshold voltage of 4.75V, making it suitable for 5V systems that need a tight margin to ensure proper operation.
• Accuracy: It boasts a high threshold accuracy which is essential for reliable system performance.
• Low Power Consumption: The MCP102T-475E/TT is designed for energy-efficient operation, which is critical for battery-operated devices and power-sensitive applications.
• Compact Package: Available in a tiny three-pin SOT-23 package, it saves valuable board space and is ideal for space-constrained applications.
• Extended Temperature Range: This device is capable of operating over an industrial temperature range, making it versatile for use in harsh environments.

The MCP102T-475E/TT voltage supervisor is an active low reset device, which means that the reset output is driven low when the monitored voltage falls below the threshold. This type of output is commonly used in digital systems for initiating a reset sequence. Additionally, the device features a built-in delay on the reset output, which prevents false triggering due to transient voltage dips, ensuring that resets are only asserted during genuine undervoltage conditions.

Overall, the MCP102T-475E/TT from Microchip Technology is an indispensable component for any system that demands reliable voltage monitoring and reset functionality. Its precision, low power consumption, and compact footprint make it an excellent choice for a wide array of applications, from consumer electronics to industrial control systems.
