Supervisors are integrated circuits that provide an interface between processors and system or peripheral components.

Maxim Integrated’s MAX6328UR30+T is a single-supply supervisor with a watchdog and a reset. It is used for safety-critical applications such as automotive, industrial, and medical systems. It is designed with a small footprint to save design space and cost.

MAX6328UR30+T Application Field

The MAX6328UR30+T is an advanced Supervisor offering features that include a manual reset input, an active-high watchdog reset output, a supply voltage supervisory input, and a power-fail comparator input. Its features accommodate a wide range of microprocessor and system reset requirements.

It is suitable for applications such as automotive cockpit and infotainment, medical instrumentation, industrial systems, and energy meter designs. Its features include the ability to monitor power-fail signals and microprocessor-directed reset signals. It is compatible with traditional response times to reset failures and provides a long reset hold time.

MAX6328UR30+T Working Principle

The MAX6328UR30+T has two independent reset outputs. The Reset_D output is designed for normal operations and is active low when triggered. The WDT_R output is designed for safety critical applications, providing a fast reset that can be used to cycle power or re-initialize a system. Both are active low.

It operates as a monitoring device and supervises several power sources as well as reset signals. The MAX6328UR30+T includes a manual reset input, an active-high watchdog reset output, and a power-fail comparator input. Its adjustable reset hold time is longer than traditional reset devices.

The MAX6328UR30+T is designed with a supply voltage boosting circuit that enables it to operate over a wide supply voltage range. The WDT_R output is driven to a high voltage level when the supply voltage falls below the trip point, initiating a power reset. It includes an internal status flag which runs continuously and activates the reset output when the input signal is out of range.

It operates with an adjustable watching circuit that monitors the input of the reset pin. It also has an adjustable watchdog time base. When the reset pin is asserted, the WDT_R output will be set to a low level, notifying the processor that a reset is needed.

The MAX6328UR30+T has features that enable it to monitor power-fail signals and microprocessor-directed reset signals. It has an additional voltage threshold feature, which allows it to trip the reset before a system power failure occurs. This provides extra protection from potential damage or unpredictable system failures.

The MAX6328UR30+T is designed for safety-critical applications, providing an early warning of system power failure and providing an effective reset protection scheme. It provides superior protection for microprocessors, system controllers, and other logic devices.
