USB3740B-A19-TR – MICROCHIP TECHNOLOGY

The Microchip Technology USB3740B-A19-TR is a high-speed USB 2.0 port controller with integrated ESD protection, specifically designed for portable consumer applications. It features a robust architecture that minimizes external components, simplifying board layout and reducing overall BOM cost. This device provides a single downstream port and offers superior signal integrity compared to discrete solutions. The typical output voltage rating is 3.3V. It is capable of delivering an output current rating of 500mA per port, suitable for charging portable devices or interfacing with USB peripherals. Packaged as a space-saving 24-pin QFN SMD, it’s ideal for densely populated PCBs. The USB3740B-A19-TR operates reliably across an extended operating temperature range of –40°C to 85°C, ensuring functionality in demanding environments. Its integrated ESD protection up to ±15kV (air gap discharge) provides added reliability in consumer electronic products.
