ADM6326-29ARTZ-R7

PMIC (Power Management ICs) are integrated circuits that perform power management functions on electronic devices. they regulate the flow of power, optimize system performance and reduce overall power consumption. PMICs are used in almost all electronic devices, including mobile phones and tablets, televisions, personal computers, automotive systems and IoT (Internet of Things) products. Among all kinds of PMIC, Supervisors are one of the most important. They are mainly used for resetting the system, monitoring power supply voltage, protecting the system from power supply failure and detecting and recording system errors.

ADM6326-29ARTZ-R7 is a member of Analog Devices\' Supervisors family, designed for monitoring power supplies and providing various types of system reset solutions. It provides the most advanced error checking, power supply monitoring, system reset and supervision solutions in a small form factor. It is suitable for a wide range of applications, including automotive, industrial, communications, automotive modules and traditional battery-powered applications.

ADM6326-29ARTZ-R7 Applications

ADM6326-29ARTZ-R7 has a wide range of applications, mainly in automotive and industrial automation. For example, it can be used in automotive engine control and power systems, factory automation, medical instrument control, communications, medical equipment, power supply control, flat panel display control, printer control and health care applications.

In the automotive field, ADM6326-29ARTZ-R7 supervisors provide a reliable reset and monitoring solution which enables the system to operate at much higher system voltages. Besides, it can be used in very strict environments, such as vibration, shock, wetness and temperature changes. Furthermore, its wide operating temperature range and AEC-Q100 qualified rating make it a great choice for automotive applications.

In the industrial automation field, ADM6326-29ARTZ-R7 provides excellent protection for system reliability in harsh industrial environment. It can be used in communication, metering, motion control and industrial control systems where power supply voltage is monitored and spurious start-up reset pulses are prevented.

ADM6326-29ARTZ-R7 Working Principle

ADM6326-29ARTZ-R7 is a very fast supervisor with a response time of less than 1µs, which allows it to react almost instantly to changes in power supply voltage or temperature. It is designed to operate over a wide input voltage range from 1.8V to 5.5V, and has an operating temperature range from -40°C to +125°C.

The working principle of ADM6326-29ARTZ-R7 is quite simple – when the input voltage goes above or below predetermined levels, the supervisor activates its built-in reset circuit and restores the system to a predetermined state (which can be either the system\'s power-on state or a pre-boot state).

The reset circuit is based on a fixed delay timer and a user-configurable delay timer. The fixed delay timer delays the output enable of the supervisor after the power supply voltage has risen above or dropped below the programmed threshold. The user-configurable delay timer allows the user to adjust the reset time by adding extra delay. This allows the system to remain in reset until the system has stabilised and to start again reliably.

ADM6326-29ARTZ-R7 also has a power supply monitoring feature. It can generate an interrupt if the power supply voltage falls below a certain threshold, allowing the system to be automatically shut down to protect from incorrect operation or damaging system components.

Conclusion

In conclusion, ADM6326-29ARTZ-R7 is an ideal solution for automotive and industrial applications requiring a reliable and robust reset and supervision solution. It provides the most advanced error checking, power supply monitoring and reset monitoring solutions in a small form factor, and its wide operating temperature range and AEC-Q100 qualified rating make it an ideal choice for automotive applications.
