Product Overview: AP2171DSG-13
The AP2171DSG-13 is a high-quality, single-channel current-limited integrated high-side power switch from Diodes Incorporated, designed for USB and other hot-swap applications. This power switch is optimized for self-powered and bus-powered Universal Serial Bus (USB) applications, where protection and control are critical to system reliability.
With an input voltage range of 2.7V to 5.5V, the AP2171DSG-13 is versatile for various USB systems. Its fast short-circuit response time ensures quick protection against any sudden or excessive current, thereby safeguarding the connected devices. The switch is also designed to limit the current to a safe level, preventing damage to sensitive components in case of a fault condition.
The AP2171DSG-13 features a 145ms typical rise time, which reduces inrush current and contributes to the stable operation of the system. It also has an output discharge function that quickly discharges the output capacitor when the switch is turned off, ensuring a safe disconnection of the USB device.
Additionally, the device offers a low on-resistance of 70mΩ, which means it can handle higher current loads with minimal voltage drop and power loss. This characteristic is particularly important for maintaining the efficiency of power delivery to the connected USB device.
With built-in over-current and thermal protection, the AP2171DSG-13 is designed to automatically shut down to prevent damage to the switch and the downstream devices. Once the fault condition is removed, the device automatically restarts, providing a robust solution for continuous operation.
The AP2171DSG-13 comes in a space-saving SOT-25 package, making it suitable for compact designs where PCB real estate is at a premium. Its green molding compound, with lead-free terminations, is RoHS compliant, aligning with environmental standards and regulations.
Overall, the AP2171DSG-13 from Diodes Incorporated is a reliable and efficient solution for applications requiring power distribution and protection. Its comprehensive feature set ensures that it can meet the rigorous demands of modern USB interfaces and other hot-swap applications.
