The TPS2421-2DDA with Hot Swap Voltage Controllers 3-20V Integ FET 0-5A Hot Swap manufactured by Texas Instruments is a low voltage, wide voltage range, hot swap controller from Texas Instruments that offers a wide range of protection and power control features. The controller provides protection against overvoltage, overcurrent, and power-on reset, as well as over-temperature and short circuit protection. This device also offers a programmable current limit, programmable undervoltage lockout (UVLO), and over-current protection (OCP). The device's integrated power MOSFET is rated up to 5A and the controller's overall power range is from 3V to 20V. This device can be used in a variety of applications, including voltage supplies, board-to-board hot swap, GPUs, and other power management applications.
