Product Description
Microchip MCP102T-195I/TT is a micropower voltage supervisor IC designed to monitor a single voltage supply line of 1.9V. It comes in a compact 3-pin SOT-23 surface mount package, making it ideal for space-constrained electronics and embedded systems.
This voltage supervisor ensures reliable operation of microcontrollers by holding them in reset during brownout or power-loss events via its active-low reset pin output. The ultra-low supply current of just 1.75 μA (steady-state maximum) helps maximize battery life and reduce power consumption in portable and low-power applications.
The MCP102T-195I/TT operates effectively with supply voltages ranging from 1V to 5.5V, accommodating a variety of system voltages. Its reset active time includes a reset delay timer with a typical delay of 130 milliseconds, providing stable reset signaling during power transitions.
It is specified to operate reliably over a wide temperature range of -40°C to +85°C, suitable for industrial and commercial electronic systems. The small form factor (3.04 mm length, 1.4 mm width, and 1.02 mm height) of the SOT-23 package also enables its use in compact designs.
This voltage supervisor requires no manual reset or watchdog timer, simplifying implementation and reducing component count. It is a cost-effective solution in power management ICs for embedded electronics, industrial control, and consumer devices requiring precise monitoring of power supply levels.
Ultra-low supply current minimizes power consumption. Active-low reset output ensures robust microcontroller supervision. Wide operating voltage and temperature ranges. Compact SOT-23 package suitable for surface mounting.
Detects power failures and provides reset during brownout. Eliminates need for manual reset or watchdog circuitry.
The MCP102 series from Microchip delivers reliable supervisory functions essential for maintaining system stability in embedded and power-sensitive applications. Explore additional products in the Voltage Supervisors category on EnvMart for complete power management solutions.
