Power management integrated circuits (PMICs) are semiconductor devices that are used to manage the power of various electronic components in a system. They can be used to monitor power supply voltages and current, control power rail switching, activate load switches, and diagnose problems. Supervisors are a type of PMIC that are most often used to monitor the power-on state of a device and to provide system reset signals when a power failure is detected.

The MAX6723UTSHD3+T is a nanoPower dual supervisor IC from Maxim Integrated which provides a high level of power-on reset protection. The IC consists of two independent power supervisors with active low reset signals, each of which has an integrated voltage monitor to detect an undervoltage condition. The reset delay times of the supervisors can be independently adjusted by setting external capacitors. The MAX6723UTSHD3+T can also be used in combination with an external microprocessor to provide system reset following monitoring of pre-set conditions.

Application Field

The MAX6723UTSHD3+T is most commonly used in digital systems, such as microprocessors, which need to be protected from power failures. The MAX6723UTSHD3+T provides a low-cost solution that is both compact and reliable. It can also be used in automotive systems, industrial power supplies, battery-backed systems, and telecommunications.

Working Principle

The MAX6723UTSHD3+T is designed to monitor the power supply voltage and activate a reset signal when the voltage falls below a preset threshold. The reset signal is routed to the microprocessor and other components, which causes them to reset to their original state. This prevents them from becoming damaged or corrupted due to a power anomaly. The reset signal can also be used to activate external load switches or indicators.

The MAX6723UTSHD3+T can also be used in combination with an external microprocessor to provide system reset following monitoring of pre-set conditions. This is achieved by setting the reset delay time, which is the amount of time the supervisors wait before generating the reset signal. This can be adjusted by connecting external capacitors to the supervisor\'s control pins. The MAX6723UTSHD3+T also provides an active low reset signal which can be used to reset multiple internal and external components.

The MAX6723UTSHD3+T is a versatile power supervisor IC that provides reliable, low-cost protection from power anomalies. It is designed to be used in conjunction with an external microprocessor to detect pre-programmed conditions and provide system reset, and can be used in numerous applications including automotive, industrial, and telecommunications.
