The MAX705CPA+ by Analog Devices is a microprocessor supervisory circuit that simplifies power monitoring in µP systems. It provides essential functions including a reset output during power-up, power-down, and brownout conditions, a watchdog timer with a 1.6-second timeout, a 1.25V threshold detector for power-fail or low-battery warnings, and an active-low manual-reset input.
This device ensures system reliability and accuracy, reducing the need for discrete components. It features a precision supply voltage monitor that generates a reset pulse when the supply voltage drops below 4.65V. The MAX705CPA+ is housed in an 8-pin DIP package, suitable for through-hole mounting.
Key features include a guaranteed RESET valid at VCC = 1V, a 200ms reset pulse width, and a debounced TTL/CMOS-compatible manual-reset input. The operating temperature range is 0°C to 70°C (TA). This component is designed for critical µP power monitoring applications in computers, controllers, and intelligent instruments.
