Texas Instruments High-Performance Analog Hot Swap Controllers UCC2915DP

The UCC2915DP is a programmable hot swap power manager designed for efficient power management and circuit protection. 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 rapid 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 UCC2915DP also incorporates thermal shutdown, undervoltage lockout, and a fault-output indicator. In sleep mode, it consumes only 100 ¬µA of supply current, making it suitable for low-power applications. The device is available in low thermal resistance SOIC and TSSOP packages, facilitating efficient thermal management.
