Microchip 1 Voltage Supervisor 3-Pin SOT-23 MCP130T-450I/TT

Microchip MCP130T-450I/TT is a reliable 1 voltage supervisor housed in a 3-pin SOT-23 surface mount package, designed to monitor supply voltage levels and hold microcontrollers in reset during under-voltage or brownout conditions. It ensures microcontrollers start only when the supply voltage reaches a stable operating level.

The MCP130 integrates an internal 5 kΩ pull-up resistor and provides an open drain active low output signal, which remains active for approximately 700 ms after reset assertion, safeguarding system startup stability. It monitors a voltage of 4.37 V with an accuracy of ±125 mV over the temperature range, suitable for 5 V systems.

This supervisor operates from a minimum supply voltage of 1 V up to a maximum of 5.5 V, with an operating temperature range from -40°C to 85°C, making it fit for industrial and commercial electronic applications. Its compact package dimensions of 2.9 mm length, 1.3 mm width, and height of 950 μm facilitate easy PCB surface mounting.

The device consumes a low typical operating current of 45 μA, thus minimizing power drain. It features no watchdog timer or manual reset, focusing solely on supply voltage supervision and reset signal generation through an open-drain active low output driver.

Commonly used in industrial, manufacturing, embedded systems, and power management applications, the MCP130T-450I/TT enhances device reliability during power-up, brownouts, and power loss scenarios. Its Thailand manufacturing origin assures quality compliance.

This device holds microcontroller in reset until supply voltage stabilizes. It features an internal 5 kΩ pull-up resistor for reliable reset signal. The typical reset active time is 700 ms, ensuring stable startup conditions.
