LM5069MM-2

The LM5069MM-2 is a part of Texas Instruments' family of hot-swap controllers, designed to protect electronic systems from inrush current during hot-plugging events. It is suitable for applications in server and telecom environments. The device manages the power-up sequence by controlling the inrush current through an external N-channel MOSFET, ensuring a smooth startup.
Key features include adjustable overcurrent protection, undervoltage lockout, and thermal shutdown, which enhance reliability. The LM5069MM-2 also supports fault management, with a fault timer to prevent damage from sustained overcurrent conditions. This variant (-2) features a latch-off mode upon detecting a fault, requiring a reset or power cycle to restart, which is ideal in scenarios where manual intervention is preferred for system checks before reset.
The LM5069MM-2 operates over a wide supply voltage range, making it versatile for various applications. Its integration of comprehensive protective features reduces the need for additional components, simplifying design and saving space on the circuit board.
