MCP112T-475E/LB Voltage Supervisor IC by Microchip Technology

The MCP112T-475E/LB is a compact, highly reliable voltage supervisor device designed by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This particular model is engineered to maintain accurate monitoring of power supplies, ensuring that microcontrollers and digital systems operate within safe voltage levels. It is an ideal component for applications where power supply stability is crucial, such as in portable devices, automotive electronics, and industrial control systems.

This voltage supervisor IC is tailored to trigger a reset signal whenever the monitored voltage drops below the factory programmed threshold of 4.75V. The reset signal is maintained for a minimum of 350 ms after the supply voltage rises above the designated threshold, providing ample time for the system to stabilize upon power-up or during a brown-out condition. The MCP112T-475E/LB variant comes in a 3-pin TO-92 package, which is widely used and suitable for through-hole mounting, making it a versatile choice for various PCB designs.

Key features of the MCP112T-475E/LB include:

• Low supply current of 1 µA (typical), which is highly beneficial for battery-operated devices where power conservation is critical.
• High accuracy threshold voltage (±125 mV at +25°C), ensuring precise monitoring and control of the system power supply.
• Wide operating temperature range from -40°C to +125°C, allowing the device to function reliably in extreme environments.
• Open-drain output, which provides the flexibility to connect the output to a voltage level higher than V<sub>DD and to wire-OR multiple outputs together.

The MCP112T-475E/LB is a testament to Microchip Technology's commitment to providing solutions that enhance system reliability and prevent data corruption caused by unpredictable power fluctuations. By integrating this voltage supervisor into your design, you can ensure that your electronic systems operate safely and efficiently, with minimal risk of unexpected resets or malfunctions due to power supply issues.
