Maxim Integrated MAX4987BESA+T USB 2.0 Switch with Fault Blanking

The Maxim Integrated MAX4987BESA+T is a high-performance, low-power USB 2.0 high-speed analog switch with fault blanking, designed for applications requiring switching between USB sources. This compact device comes in a space-saving 8-pin NSOIC package, making it an ideal solution for portable electronics where board space is at a premium.

Featuring a single USB 2.0 high-speed (480Mbps) switch, the MAX4987BESA+T offers the flexibility to route signals as needed in your USB applications. Its unique fault blanking feature helps to avoid erroneous switching by ignoring transient faults, such as those caused by the hot-plugging of USB devices, which ensures a more stable and reliable USB interface.

The MAX4987BESA+T is equipped with an overcurrent fault detection mechanism that temporarily disconnects the switch during overcurrent events, safeguarding downstream circuits from potential damage. After the fault condition is removed, the switch automatically reconnects, providing a seamless experience for the user.

With its low on-capacitance (C<sub>ON) and on-resistance (R<sub>ON), the device guarantees minimal signal distortion and attenuation, ensuring high signal integrity for USB data lines. The low power consumption of the MAX4987BESA+T makes it suitable for battery-operated devices, helping to extend battery life and reduce power-related concerns.

Key features of the MAX4987BESA+T include:

• USB 2.0 High-Speed (480Mbps) Compatible
• Low On-Capacitance and On-Resistance
• Fault Blanking to Ignore Transient Faults
• Automatic Reconnection After Fault Clearance
• Overcurrent Fault Detection
• Extended -40°C to +85°C Operating Temperature Range

The MAX4987BESA+T is ideal for a variety of applications, including cell phones, PDAs, digital cameras, and other USB peripheral devices. Its robust design and fault-protection features make it a reliable choice for designers looking to implement USB switching functionality with an added layer of safety and efficiency. Maxim Integrated's commitment to quality ensures that the MAX4987BESA+T meets the stringent requirements of today's electronic devices.
