Microchip Technology MCP102T-315E/LB Voltage Supervisor IC

The MCP102T-315E/LB is a compact, highly reliable voltage supervisor device designed by Microchip Technology to provide an essential protective mechanism for microcontrollers and digital systems. This supervisor IC monitors the power supply voltage and maintains system integrity by ensuring that the voltage levels remain within acceptable thresholds for the proper functioning of electronic components.

Featuring a preset threshold voltage of 3.15V, the MCP102T-315E/LB is ideal for 3.3V systems, where precise voltage monitoring is critical. The device's active-low /RESET output is asserted when the monitored voltage falls below the factory-set threshold, providing a clear signal for the system to initiate corrective actions such as a reset or shutdown to prevent potential damage or data corruption.

The MCP102T-315E/LB comes in a 3-pin SOT-23 package, making it suitable for space-constrained applications. Its small footprint does not compromise its performance, as it offers a tight tolerance of ±1.5% for the threshold voltage, ensuring accurate monitoring even in the most demanding scenarios.

Key features of the MCP102T-315E/LB include:

• Voltage Threshold: Preset 3.15V for precise monitoring of 3.3V power supplies.
• Output Type: Active-low /RESET signal which ensures compatibility with most microcontroller and digital system interfaces.
• Reset Delay Time: Built-in delay to avoid false triggering due to transient conditions, improving system stability.
• Supply Voltage Range: Operates over a wide voltage range, accommodating various application requirements.
• Low Power Consumption: Designed for energy-efficient operation, which is crucial for battery-powered devices.
• Operating Temperature: Suitable for industrial applications with an operating temperature range of -40°C to +85°C.
• Package: Available in a small SOT-23 package that is ideal for PCBs with limited space.

The MCP102T-315E/LB is a versatile voltage supervisor that is well-suited for a wide array of applications, including computers, embedded systems, portable electronics, and any other system that requires reliable voltage monitoring to safeguard against power supply anomalies. Its ease of integration and robust feature set make it an excellent choice for designers looking to enhance the resilience and stability of their electronic systems.
