The MCP121T-450E/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 a specific operating voltage of 4.38V. It features an active-low reset signal with an open-drain or open-collector output. The reset delay is specified as a minimum of 80ms, with typical values around 120ms as indicated in the datasheet.
Designed for critical microcontroller and microprocessor power-monitoring applications, the MCP121T-450E/TT is suitable for use in computers, intelligent instruments, and portable battery-powered equipment. Its ultra-low supply current of 1.75 µA (steady-state maximum) makes it ideal for power-sensitive designs.
The supervisor is available in a compact SOT-23-3 surface-mount package, making it suitable for space-constrained PCB layouts. The operating temperature range is -40°C to +125°C, ensuring reliable performance in various environmental conditions.
