Maxim Integrated MAX14604ETA+T Overvoltage Protection Controller

The MAX14604ETA+T from Maxim Integrated is an advanced overvoltage protection controller designed to safeguard low-voltage systems against damaging input voltage conditions. This compact, high-performance device is an ideal solution for protecting sensitive electronics in a wide range of applications, including portable devices, wearables, and smart technology products.

Key Features

• Overvoltage Protection: The MAX14604ETA+T offers robust overvoltage protection (OVP) up to 36V, ensuring that connected devices are shielded from unexpected voltage spikes.
• Adjustable OVP Threshold: It provides the flexibility to set the overvoltage protection threshold via external resistors, allowing for precise control tailored to specific application requirements.
• Low On-Resistance: The device boasts a low on-resistance (RON) of just 70mΩ (typical), minimizing voltage drop and power loss across the internal FET.
• Wide Operating Voltage Range: With an operating range of 2.5V to 5.5V, the MAX14604ETA+T is versatile and can be used in a variety of low-voltage applications.
• Small Form Factor: Housed in a tiny 12-pin TDFN package (3mm x 3mm), this controller is perfect for space-constrained designs.

Applications

• Smartphones and Tablets
• Portable Media Players
• Wearable Devices
• Portable Medical Devices
• Smart Home and IoT Devices

Additional Benefits

The MAX14604ETA+T also features an automatic retry function, which enables the device to automatically attempt to re-enable the FET after an overvoltage condition subsides. This feature helps to ensure uninterrupted operation of the protected device without the need for manual intervention.

For design flexibility, the device offers an active-low open-drain fault indicator (FLT) that signals the presence of an overvoltage condition. This allows for easy integration with microcontrollers or other monitoring systems to take appropriate actions when an overvoltage event is detected.

With its combination of protection features, small size, and ease of use, the MAX14604ETA+T is an excellent choice for engineers looking to incorporate overvoltage protection into their next-generation electronic designs.
