The MAX6805US26D3+T is an ultra low-power supervisor that operates over a wide temperature range. It is suitable for a variety of portable applications where power conservation and fail-safe backup are essential. The MAX6805US26D3+T supervises the main power supply and will reset the system if it senses an over-voltage, under-voltage, or power-surge fault.

The MAX6805US26D3+T has an adjustable tolerance window that can be programmed from 2.6 to 5.5 volts, and is available in many packages. It also has an active-low open-drain manual reset output so that the user can reset their system at any time. The MAX6805US26D3+T is designed to protect against accidental and destructive events, such as short-circuits, brownouts, and power surges.

The MAX6805US26D3+T has a wide range of applications. It is ideal for embedded applications such as microcontroller-based systems, where it can be integrated into the system as an intelligent reset circuit and provide an additional level of protection. It is commonly used in portable medical and industrial projects, automotive systems, and as a power source for microprocessors.

The MAX6805US26D3+T is also very suitable for board-level monitoring of systems with multiple power supplies, providing the ability to simultaneously monitor the input voltage levels of multiple power buses for over- and under-voltage. This allows system designers to develop a safeguard against unexpected voltages or current levels that, if left unchecked, could cause costly and potentially dangerous failures in their designs.

The MAX6805US26D3+T has a very low operating current that helps to maintain power conservation in portable systems. Additionally, it is particularly resistant to noise and electromagnetic interference, which makes it suitable for use in applications where harsh environmental conditions can be expected.

The working principle of the MAX6805US26D3+T is based on the comparator op-amp architecture. When the input voltage rises above or falls below the programmed threshold, the comparator activates a reset circuit. This will trigger the internal reset timer, which can be programed for a timed reset of the system or a time-out reset where the reset is automatically cleared when the input voltage returns to within the programmed window. This allows the system to instantly recover and return to a stable state.

The MAX6805US26D3+T has been designed to meet a range of safety standards, making it suitable for a wide range of applications. It is UL, EN and VDE quality certified, and has been rigorously tested to meet the stringent requirements of industrial and commercial applications.

The MAX6805US26D3+T is an ideal cost-effective solution for embedded applications which need reliable power monitoring and management. Its wide temperature range and low power consumption make it suitable for portable and harsh environment applications, as well as automotive, medical, and industrial systems.
