The MAX6385XS34D2-T is a highly integrated supervisors of voltage/window, µP supervisory, and watchdog timer. They’re extremely low power and offer very high accuracy monitoring. The operating range of the MAX6385XS34D2-T is from -40℃ to +85℃, and is often used in non-critical applications or those with a highly efficient through-hole construction.

What is PMIC - Supervisors?

PMIC - Supervisors are devices designed and manufactured to monitor, supervise and protect a variety of components and systems in applications such as smartphones, computers, servers, automotive and home appliances. Generally speaking, supervisors perform voltage/window, µP supervisory, and watchdog timer roles. They are designed to prevent system failure, and often come in the form of an integrated circuit that uses comparators and a reference voltage to detect faults, and reset functionality to get the system going again.

Application Field of MAX6385XS34D2-T

The MAX6385XS34D2-T is commonly used in systems that require low-power specific control. The MAX6385XS34D2-T is used in IoT and embedded systems to monitor battery voltage, protect the important load at the max and minimum voltage, protect against over voltage and also to protect the reset of the system against any unexpected power/voltage/frequency variations. It also offers adjustable watchdog timer and provides monitoring functions for voltage/fault/temperature conditions. It\'s also used in power supply applications to supervise input and output stages of non-critical circuits.

Working Principle of MAX6385XS34D2-T

The MAX6385XS34D2-T contains advanced protection algorithms to monitor and protect system components. The Voltage Supervisory is used to monitor the system supply voltage level. The MAX6385XS34D2-T also contains a µP Supervisory that is used to monitor µP operation. This is done by measuring the amount of time that the µP takes to execute instructions. The µP Supervisory monitors PVCC (Voltage) and VDD (Voltage Stabilization Division) to protect the µP. With the MAX6385XS34D2-T, the DNV_S circuit checks for any open or potential short circuit. If any potential shorts or open circuits are found, the voltage supply is disabled to prevent any damage. The Watchdog timer monitors the µP and detects any faults or unexpected events that could cause system failure.

The MAX6385XS34D2-T also contains a reset control circuit that provides protection against faulty or unexpected power/voltage/frequency variations as well as reset functions. When the supply voltage falls below the low threshold or rises above the high threshold, a reset signal is sent to the system, which then re-establishes normal operation. This reset control circuit also guards against ESD, power glitches, and other unexpected events.

The MAX6385XS34D2-T also includes multiple protection features like power-on reset (POR), brown-out detect (BOD), frequency monitor & tracking (FMT), and slow power-on reset (SPOR). These features provide protection from power glitches, ESD events and also protect the system from any unexpected events.

Conclusion

The MAX6385XS34D2-T is a superb PMIC - Supervisors device and is especially suitable for embedded systems and IoT applications. Its advanced protection algorithms enable the MAX6385XS34D2-T to accurately monitor and protect against voltage/fault/temperature conditions as well as any unexpected power/voltage/frequency variations. It also offers adjustable watchdog timer and reset control circuit, which provides protection and resets the system when necessary, so that the system can re-establish normal operation.
