Maxim Integrated MAX4845ELT+ Overvoltage Protection Controller

The Maxim Integrated MAX4845ELT+ is a high-precision, low-current overvoltage protection controller designed to safeguard sensitive electronics from harmful voltage levels. This tiny, yet powerful, controller is encapsulated in a compact 6-pin Thin SOT-23 package, making it an ideal choice for space-constrained applications.

The MAX4845ELT+ offers a robust defense against overvoltage conditions, ensuring that devices such as smartphones, tablets, and other portable electronics are protected from voltage transients and spikes that can occur in everyday usage. Its precise overvoltage protection threshold is factory set at a nominal voltage, which can be selected from a range to suit various application needs.

This controller is engineered with an internal MOSFET that disconnects the load from the supply when the input voltage exceeds the overvoltage threshold. The quick response time of the MAX4845ELT+ helps prevent damage to the load, thereby increasing the reliability and longevity of the protected device. Moreover, its low quiescent current minimizes power consumption when the device is in standby mode, which is critical for battery-powered applications.

Key features of the MAX4845ELT+ include:

• Factory Preset Overvoltage Protection Threshold
• Low Quiescent Current for Extended Battery Life
• Fast Response Time to Overvoltage Events
• Internal MOSFET to Disconnect Load During Overvoltage
• Compact 6-Pin Thin SOT-23 Package for Space-Saving Designs

The device also boasts an overtemperature protection feature that shuts down the internal MOSFET if the junction temperature exceeds safe operational limits, adding an extra layer of safety.

With its combination of precision, speed, and compactness, the Maxim Integrated MAX4845ELT+ is an excellent choice for designers looking to integrate overvoltage protection into their next-generation portable electronics. Its reliability and efficiency make it a standout component in the field of circuit protection technology.
