MAX6802UR29D2+T is a supervisor that is designed to provide excellent monitoring functions. This supervisor can monitor and hold two lines (RESET, PWRONx) in a system and provide limit current protection. It has been specifically designed to monitor high voltage and low voltage supplies in battery, USB, and adapter systems. MAX6802UR29D2+T has a high performance, low on-resistance slew rate LIMITED switch that allows higher switching rates to be achieved, making it suitable for applications such as port protection, USB over-current protection, and processor power sequencing.

The MAX6802UR29D2+T applications mainly include supervisory functions to monitor the power supply voltage, system reset, and charge and/or monitor buttons. The built-in 50mA current limit feature provides protection from droop and inrush current events that could damage other components in the system. The MAX6802UR29D2+T monitors the RESET/PWRONx and switches VDD/VSS to GND in response to a detected problem. It can also be used as a logic-controlled reset block.

The MAX6802UR29D2+T works through various power monitoring features, including reset and power-on monitoring, over-voltage protection, and short-circuit protection. When the monitoring conditions are met, the MAX6802UR29D2+T will initiate a reset sequence to notify other system components. Additionally, it has a built-in voltage and temperature monitor that allows for adjustable trip points for reset and power-on events.

The feature of the MAX6802UR29D2+T that makes it a great choice for power monitoring is its on-chip current limit logic and slew rate controlled pin. The current limit feature holds the current at a pre-set level during inrush events, preventing voltage droop or short-circuiting of the power supply. The slew rate limiting protects against false triggering that may occur during large inrush events, while still allowing fast switching of the current.

The MAX6802UR29D2+T is easy to use and is designed to maximize system reliability and satisfy the most stringent noise requirements. It is capable of operating from a single power supply and is offered in an 8-pin MSP package, which is ideal for a wide variety of applications. Additionally, it is RoHS compliant, making it a great choice for cost-sensitive designs.

Overall, the MAX6802UR29D2+T provides an excellent power supervision and protection solution for a lot of applications. It has numerous features that make it very reliable and robust. Its current limit and slew rate control capabilities make it highly suitable for over-current protection and power sequencing applications, while its high performance and low on-resistance features make it ideal for protection against power supply droop, short-circuiting, and other over-voltage events. Additionally, its small package size makes it suitable for small space applications.
