Microchip MCP130T-300I/TT Voltage Supervisor, 3V Threshold, SOT-23-3
Microchip MCP130T-300I/TT voltage supervisor ensures reliable microcontroller reset with 3V threshold, 350ms delay, SOT-23.
The Microchip MCP130T-300I/TT is a precision voltage supervisory circuit designed to keep your microcontroller in reset until the system voltage has reached the proper level and stabilised, ensuring reliable operation during power-up and power-down sequences. It also protects against brown-out conditions, resetting the microcontroller if the supply voltage falls below a safe operating level. This supervisory IC features an open-drain output with an internal 5kΩ pull-up resistor and an active-low reset pin, providing a simple and robust interface. It holds the reset signal for 350ms (typical) after the voltage recovers, giving the system ample time to stabilise. For 3V systems it offers an accuracy of ±75mV, while 5V systems benefit from ±125mV accuracy. Operating over an extended industrial temperature range of -40°C to +85°C, this device is qualified to AEC-Q100 for automotive applications, making it suitable for demanding environments. With a typical operating current of only 45μA, it is an energy-efficient choice for battery-powered devices. Supplied in a compact SOT-23 surface-mount package with 3 pins, this supervisor is ideal for space-constrained designs. Whether you are developing automotive electronics, industrial controls, or consumer devices, the MCP130T-300I/TT ensures your microcontroller operates reliably, protecting your system from voltage fluctuations and power interruptions. Its monitoring features and low power consumption make it a versatile solution for applications where stable operation is critical.
