The MAX805TCPA+ from Maxim Integrated is a robust and versatile microprocessor (µP) supervisory circuit, designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in system applications. The MAX805TCPA+ ensures that the µP is reset to a known state during power-up, power-down, and brown-out conditions.

Key Features

• Precision Monitoring: It includes a precision voltage monitor that keeps a check on the system voltage levels and ensures they remain within the acceptable range for reliable operation.
• Power-On Reset: The device generates a reset signal whenever the supply voltage falls below the reset threshold, ensuring the system powers on in a predictable state.
• Manual Reset: A manual reset feature allows for an external signal to initiate a reset, providing additional control to the system operator or peripheral circuitry.
• Low Power Consumption: With its low power consumption, the MAX805TCPA+ is ideal for power-sensitive applications.
• Wide Operating Temperature: It operates over a wide temperature range, making it suitable for various environments and applications.
