Power management integrated circuits (PMICs) are an important source of power supply systems in modern society. PMICs are responsible for controlling and monitoring the power that flows throughout the system and can provide a wide range of functions, ranging from data line management to system protection and dynamic power management. The MAX702CPA+ is an example of a PMIC, specifically one that deals with supervisory circuits.
Supervisory circuits, sometimes known as reset or watch-dog circuits, are used to ensure that a system remains operational and in a defined operating state. The MAX702CPA+ is an ultra-low-power, low-voltage microprocessor supervisory circuit designed for battery-powered applications. It is a precision, low-power bipolar voltage monitor for microcontroller and ASIC power-up and power-down control, as well as reset control.
The MAX702CPA+ incorporates an internal power-on reset circuit, watchdog timer, and a precision window comparator into a single 8-pin package. The MAX702CPA+ provides 3.9V to 5.5V input voltage range, programmed reset threshold voltages ranging from 1.1V to 4.63V, and an integrated 0.8V reference. It also can provide a reset pulse width between 50 μs and 600 ms, with a watchdog timeout period of 2 ms to 32 seconds.
The MAX702CPA+ is highly accurate, with an accuracy of ±1% over the full temperature range, making it ideal for microprocessor-based system reset and power management. It also features a low-power standby mode, with a 5 μA typical supply current, and a low minimum reset pulse width of 50 μs.
The MAX702CPA+ is designed to be used in a variety of different applications, such as; industrial and consumer electronics, automotive, and medical. These applications may include; battery-powered handheld devices, automotive systems, medical device systems, consumer electronic devices, and factory automation equipment.
The primary function of the MAX702CPA+ is to protect integrated circuits from malfunction due to environmental changes and other external interferences. It works by monitoring the voltage of the power supply, and triggering a reset when the voltage falls outside of a predetermined range. This ensures that the system remains operational, and in a defined state, despite any external interference.
The MAX702CPA+ also features power-off reset functionality, which prevents an internal watchdog trigger from causing an unintentional reset of system circuitry while the device is in a powered-off state. This functionality is important for battery-powered applications, as it prevents the unintentional resetting of the system when the battery is being charged or replaced.
In conclusion, the MAX702CPA+ is an ultra-low-power, low-voltage microprocessor supervisory circuit that provides reset and power-on control for microcontrollers, ASICs, and other battery-powered applications. It features integrated functions such as an internal power-on reset circuit, watchdog timer, and a precision window comparator, with a reset pulse width between 50 μs and 600 ms and watchdog timeout periods ranging from 2 ms to 32 seconds. This allows it to be used in a variety of applications, such as; automotive, industrial and consumer electronics, and medical devices.
