Microchip 1 Voltage Supervisor 3-Pin SOT-23 MCP130T-270I/TT 2.62V Monitored Voltage Surface Mount

Microchip MCP130T-270I/TT is a precise voltage supervisor designed to ensure microcontrollers and other devices remain in reset state during power instability or low voltage conditions. This device is packaged in a compact 3-pin SOT-23 surface mount case ideal for space-constrained electronic designs.

The MCP130 series monitors the supply voltage and asserts an active-low reset signal when voltage drops below the 2.62 V threshold. Featuring an internal 5 kilo-ohm pull-up resistor and open drain output, it simplifies interfacing and system integration. The reset signal remains active for about 700 milliseconds to allow systems to stabilize during power events.

This component operates efficiently with a typical current of 45 microamperes over a broad industrial temperature range from -40°C to +85°C. It supports a maximum supply voltage of 5.5 volts and starts functioning reliably from supply levels as low as 1 volt. The MCP130T-270I/TT does not include watchdog or manual reset features, focusing solely on voltage supervision for enhanced system reliability.

The compact physical dimensions - 2.9 mm length, 1.3 mm width, and 950 micrometer height - allow for high-density PCB layouts in consumer electronics, industrial controllers, and automotive applications.

Typical use cases include microcontroller reset control during power failures or brownout conditions in embedded systems, industrial automation, power management circuits, and other electronic devices requiring stable startup and operation.

Holds microcontroller in reset until supply voltage reaches stable operating level. Monitors voltage threshold at 2.62 V to trigger reset. Open drain, active low output simplifies system integration. Internal 5 kΩ pull-up resistor included.

700 ms reset active time ensures stable system startup. Operates from -40°C to 85°C suitable for industrial environments. Compact surface mount SOT-23 package fits dense PCB layouts. Typical operating current is 45 μA for energy-efficient designs.

Maximum supply voltage 5.5 V and minimum supply voltage 1 V. Focus on voltage supervision without watchdog or manual reset functions.
