The MAX14528ETA+ from Maxim Integrated is a high-performance, overvoltage-protected switch designed to safeguard low-voltage systems against high-voltage faults up to +28V. This advanced protection device is ideal for applications that require precise control and robust protection, such as portable electronics, data communication devices, and battery-powered equipment.

Key Features

• Overvoltage Protection: The device can endure temporary overvoltage conditions up to +28V, making it suitable for harsh electrical environments.
• High Efficiency: Low RON (resistance when on) of just 100mΩ minimizes power loss and ensures efficient operation, which is critical for battery-powered devices.
• Adjustable Overvoltage Lockout (OVLO): The OVLO threshold is adjustable through external resistors, providing design flexibility to meet specific application requirements.
• Thermal Shutdown Protection: The built-in thermal shutdown feature prevents the device from overheating, thereby enhancing system reliability.
• Reverse Current Blocking: When the switch is off, it blocks reverse current, which helps to prevent damage to downstream components.
• Small Package: Available in a compact, 8-pin TDFN package, the MAX14528ETA+ saves valuable board space in space-constrained applications.
