MAX4845ELT+T

The MAX4845ELT+T is an advanced overvoltage protection device designed for portable electronics, offering protection for systems susceptible to overvoltage conditions, such as those that rely on external power sources. It features a low 36mΩ on-resistance and can handle input voltages up to +28V. This device ensures safe operation by blocking voltages that exceed a set threshold, typically around 6V, and disconnects the load by turning off an internal switch to prevent damage to downstream components.
The MAX4845ELT+T operates over a -40°C to +85°C temperature range, making it suitable for various environmental conditions. It includes integrated thermal shutdown protection to safeguard against overheating and a reverse-current blocking feature to prevent backflow of current. The device's compact 6-pin SOT23 package allows for space-efficient designs.
Common applications include smartphones, tablets, and other portable devices that require robust protection against input overvoltage. Its efficiency and reliability make it an ideal choice for safeguarding sensitive electronic components from power surges or improper connections.

The MAX4845ELT+T is a triple USB switch designed for USB host and peripheral ports. Equivalent products include the TPS2065 from Texas Instruments, the AP2142 from Diodes Incorporated, and the NCP380 series from ON Semiconductor. These devices offer similar functionality in protecting USB ports with current limiting, over-temperature, and short-circuit protections. Always verify specific feature compatibility to ensure an exact match for your application.

The MAX4845ELT+T is a highly integrated overvoltage protection device designed to safeguard low-voltage systems against high-voltage transients. Key features include:
