Introduction: MAX805TCPA is a micropower supervisor IC, which is specifically designed for the application in DC/DC and AC/DC power converters. This IC provides low-power monitoring, fault reporting, and voltage-threshold detection.

Application Field: MAX805TCPA has wide applications in DC/DC power-supply supervision, such as in embedded systems, motor controllers, and industrial control systems. It has excellent energy efficiency, and the elimination of external components guarantees a more robust operation.

Key Features:MAX805TCPA has outstanding features that make it suitable for power-supply supervision in different applications. These features include:

• Multiple fixed-voltage levels from 4.65V to 5.45V with a ±1% accuracy
• Minimum supply voltage of 1V in quiescent mode
• Fast start-up and submillisecond response time
• Programmable reset timeouts ranging from 0.2ms to 10ms
• Operating temperature range of -40°C to+85°C

Working Principle: MAX805TCPA operates in two different modes of operation; Active and Sleep. In the Active mode, the IC monitor’s supply voltage, and allows user-programmable reset timeouts. In Sleep Mode, the IC monitors the supply voltage while consuming a very low quiescent current. Inboth modes, the INT output is asserted, which indicates whether the monitored voltage is within the threshold limits.

Conclusion: MAX805TCPA is a micropower supervisor IC, which is specifically designed for the application in DC/DC and AC/DC power converters. This IC provides low-power monitoring, fault reporting, and voltage-threshold detection. Its features, including multiple fixed-voltage levels, minimum supply voltage, fast start-up, and submillisecond response time, make MAX805TCPA suitable for power-supply supervision in different applications. It operates in two different modes and the INT output is asserted to indicate whether the monitored voltage is within the threshold limits.
