Microchip Technology MCP111T-195I/LB Voltage Supervisor

The MCP111T-195I/LB is a highly precise voltage supervisor component designed and manufactured by Microchip Technology. This compact and efficient device is a crucial component for microcontroller-based systems, ensuring reliable operation by monitoring the power supply voltage and providing a reset signal to the microcontroller during power-up, power-down, or brown-out conditions.

The MCP111T-195I/LB operates over a wide temperature range, making it suitable for various applications, including consumer electronics, automotive systems, and industrial controls. Its temperature range, from -40°C to +85°C, allows for reliable operation in environments that experience extreme temperature variations.

This voltage supervisor has a preset trigger threshold voltage of 1.95V, which is particularly useful in low-voltage applications. When the supply voltage falls below this threshold, the MCP111T-195I/LB asserts a reset signal, holding the microcontroller in a reset state until stable conditions are detected. The reset output remains active for a minimum of 350 ms after the supply voltage rises above the reset voltage threshold, ensuring the system has adequate time to stabilize.

Featuring a low supply current of just 1 µA (typical), the MCP111T-195I/LB is an energy-efficient choice for battery-operated devices. This low power consumption helps in prolonging battery life and reducing the overall power requirements of the system.

The device is available in a compact 3-pin SOT-23 package, which is ideal for space-constrained applications. Its small footprint allows for easy integration into various designs without significantly impacting the overall size of the end product.

Key features of the MCP111T-195I/LB include:

• Precision voltage monitoring for 1.95V supply lines
• Extended temperature range operation (-40°C to +85°C)
• Low supply current: 1 µA (typ.)
• 350 ms minimum reset active time
• Compact SOT-23 packaging

Overall, the MCP111T-195I/LB from Microchip Technology is a reliable and cost-effective solution for system voltage supervision, providing peace of mind that your electronic systems will operate as intended, even under adverse power conditions.
