Texas Instruments High-Performance Analog Hot Swap Controllers UCC3915PWPTR

The UCC3915PWPTR is a programmable hot swap power manager designed to provide power management, hot-swap capability, and circuit breaker functions. It operates within a voltage range of 7 V to 15 V and features an integrated 0.15-,Ѷ power MOSFET. The device allows for digital programming of the fault current limit from 0 A to 3 A with a resolution of 0.25 A, and it can source a maximum output current of 4 A for fast charging of output capacitors. Key functionalities include programmable on time, startup delay, and a fixed 2% duty cycle to limit average output power during faults. The UCC3915PWPTR also includes thermal shutdown protection, an open-drain fault-output indicator, and operates with a low supply current of 1 mA, reducing to 100 ¬µA in sleep mode. The device is available in low thermal resistance packaging options, including SOIC and TSSOP, making it suitable for various applications requiring reliable hot swap capabilities.
