Product Overview: AP2161FMG-7 from Diodes Incorporated

The AP2161FMG-7 is a high-performance, single-channel current-limited integrated high-side power switch, developed by 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.

Encased in a space-saving SOT-25 package, the AP2161FMG-7 is equipped with a range of features that ensure protection and stable operation of the connected peripherals. With an input voltage range of 2.7V to 5.5V, it is suitable for a variety of low voltage applications beyond just USB, including portable and battery-powered devices.

Key Features

• Current Limiting: The device offers programmable current limiting to protect the host device from overcurrent conditions. This is essential for preventing damage to USB ports and connected devices.
• Fast Response Time: The AP2161FMG-7 reacts quickly to fault conditions, with a fast response time that helps to minimize the risk of system damage.
• Thermal Shutdown: In-built thermal shutdown functionality ensures that the device and connected components are protected from excessive heat that could lead to failure.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates only when the supply voltage is within an acceptable range, thus safeguarding the electronics.
• Controlled Rise Time: The controlled rise time reduces the likelihood of inrush current, which can be harmful to sensitive electronic components.
• Reverse Current Blocking: This feature prevents current from flowing backward through the switch when it is powered off, further protecting the circuitry.
