The AP22814BSN-7 from Diodes Incorporated is a single-channel, current-limited, integrated high-side power switch optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. This compact and efficient device is designed for 3.3V to 5.5V operation, making it suitable for a wide range of USB peripherals and other power management tasks within its voltage range.

Key Features

• Current Limiting: The device provides precise current limiting to protect the USB port and peripheral devices from overcurrent conditions.
• Over-Temperature Protection: An integrated thermal shutdown feature ensures the device operates within safe temperature limits, thereby preventing thermal damage.
• Reverse Current Blocking: In the event of a power failure, the AP22814BSN-7 prevents reverse current from flowing back into the switch, safeguarding the upstream devices.
• Controlled Rise Time: The switch offers a controlled output rise time which reduces inrush current, minimizing the impact on the power source and other circuit components.
• Low Standby Current: The ultra-low standby current helps in reducing power consumption when the switch is not actively powering a load.
• Small Form Factor: The AP22814BSN-7 is available in a small footprint U-DFN2020-6 (Type B) package, making it ideal for applications where space is at a premium.

Applications

Due to its versatile features, the AP22814BSN-7 is well-suited for a variety of applications including but not limited to:

• USB hubs, peripherals, and portable devices
• Battery-charging circuits and power management modules
• Hot-swap supplies and load switch applications

With its combination of protection features, small package size, and efficient power management, the AP22814BSN-7 from Diodes Incorporated represents a robust solution for power distribution requirements in modern electronic devices.
