Analog Devices\' MAX6805US46D3+T is a highly accurate, low-power overvoltage supervisor in a 6-pin SOT23 packages. It is designed to monitor a wide range of voltages against undervoltage and overvoltage conditions with an accuracy of ±1.2%.Acting as an overvoltage supervisor, it provides adjustable overvoltage protection and precise undervoltage detections, indications and warning flags.

The MAX6805US46D3+T\'s application field includes industrial controls, white goods, communication equipment, laptop computers and automotive power systems. It is suited for a variety of processing and power management applications. When used with MAX6802/MAX6804, it allows multiple outputs with no cross regulation and no external components. The voltage supervisor also features a reduced supply current of 1µA.

The MAX6805US46D3+T\'s working principle is simple. The device detects the voltage of the power supply and provides a simple supervisory function for the system power supply. Whenever it detects an excessive voltage or a voltage that does not meet the specifications, a flag is set. The flag works to protect the system power supply form potential damage. If the voltage is too high, it will protect against overheating and/or damage to the electronic components of the system. It also helps to reduce power dissipation and protect against erratic system behavior.

The MAX6805US46D3+T features an adjustable overvoltage (OVP) threshold, which allows designers to determine the protection level for the power supply. The OVP protects the system\'s power supply from dangerous overvoltage levels during system power-up, power surges and power dips. The low voltage detect input also assists in maintaining a safe operating level of the power supply. When it senses an undervoltage level, an interrupt is generated to the processor.

The MAX6805US46D3+T also features an adjustable reset delay, allowing a designer to synchronize the supervisor to system reset conditions. When the supervisor detects an over or undervoltage, it waits the set delay time and then generates an assertion of a reset signal. This delay can be adjusted to achieve the most reliable system power.

The MAX6805US46D3+T is a highly integrated, low-power overvoltage supervisor with a wide voltage range and adjustable delay. Its light-weight and space-efficient design make it suitable for embedded system applications. It offers highly accurate voltage detection and protection features, eliminating the burden of system-on-chip design. The supervisor is compatible with 5V and 3.3V systems, eliminating the need for multiple power rails.

In conclusion, the MAX6805US46D3+T is a highly integrated, low-power voltage supervisor with wide voltage range and adjustable delay. It offers exceptional protection against over and undervoltage conditions, ensuring reliable system power. This allows the designer to select the desired level of protection and custom system reset delays, allowing them to optimize the system performance.
