The L6615N from STMicroelectronics is a highly integrated dual channel power distribution switch designed to manage power distribution in a variety of electronic systems. This switch is particularly suitable for applications where precision and reliability are paramount, such as USB hubs, peripheral ports, and hot-swap supplies.

Key Features

• Dual Independent Channels: The L6615N features two independent power switch channels, allowing for the control of two separate power lines with a single device.
• Overcurrent Protection: Each channel is protected against overcurrent conditions, ensuring the safety of the electronic system and preventing damage to connected devices.
• Thermal Shutdown: The built-in thermal shutdown feature prevents overheating, further enhancing the protection of the circuitry.
• Under-Voltage Lockout (UVLO): This function ensures that the power switch operates only when the input voltage is within a specified range, preventing malfunction due to low voltage conditions.
• Low Power Consumption: Designed for energy efficiency, the L6615N minimizes power consumption when active and has an even lower standby current.
• Soft-Start Function: The soft-start capability prevents inrush current at startup, which can be critical for sensitive electronic components and helps in prolonging their lifespan.
