The MCP121T-270E/TT from Microchip Technology is a micropower voltage supervisor designed to ensure reliable system operation by keeping microcontrollers in reset until system voltage stabilizes.
This device monitors a single voltage level, with this specific variant featuring a nominal threshold of 2.63V. It provides an active-low reset signal with a typical delay of 120 ms, though a minimum reset timeout of 80ms is also specified. The output configuration is open-drain or open-collector, allowing for flexible integration into various circuit designs.
Operating within an extended temperature range of -40°C to +125°C, the MCP121T-270E/TT is suitable for demanding applications. Its ultra-low supply current of 1.75 µA (maximum steady-state) makes it ideal for battery-powered equipment. The component is supplied in a compact SOT-23-3 surface-mount package, facilitating space-constrained designs.
Applications for this voltage supervisor include critical microcontroller and microprocessor power-monitoring in computers, intelligent instruments, and portable devices. Its robust design ensures that the microcontroller remains in a safe reset state during power-loss events or voltage fluctuations.
