Product Description

Microchip MCP130-450FI/TO is a precision 1-voltage supervisor IC designed to hold microcontrollers and other devices in reset during power instability conditions. Featuring a 3-pin TO-92 through hole package, it provides robust under-voltage detection and brownout reset capabilities suitable for embedded and industrial electronics applications.

The device monitors a threshold voltage of 4.37 V with ±125 mV typical accuracy in 5 V systems and asserts an active low reset via an open drain output. Its integrated 5 kΩ pull-up resistor eliminates the need for external components on the reset line. The MCP130 outputs a reset pulse typically lasting 350 milliseconds, which is sufficient to ensure microcontroller startup stability.

Operating supply voltage ranges from 1 V minimum to 5.5 V maximum, making it compatible with a variety of digital logic levels. The device performs reliably over a broad industrial temperature range of -40°C to 85°C, making it suitable for demanding environments including industrial controls, instrumentation, and automotive electronics (non-automotive standard).

The compact physical dimensions (approximately 3.94 mm height and 4.95 mm width/length) simplify PCB layout in space-constrained designs. Typical current consumption is very low at about 45 μA, which aids in battery-powered and low power applications.

This voltage supervisor is widely applicable in power management IC roles, ensuring system reliability by protecting against under-voltage conditions, unexpected power loss, and voltage dips. It supports various industrial, laboratory, and embedded system use cases requiring stable microcontroller operation and power integrity monitoring.

Ensures microcontroller reliable reset during power dips and brownouts. Compact TO-92 through hole package suitable for prototyping and low volume production. Low power consumption ideal for energy-sensitive applications.

Robust operation across industrial temperature ranges. Integrated pull-up resistor reduces bill of materials and PCB footprint. Open drain output allows wiring to multiple devices or shared reset lines.
