Texas Instruments High-Performance Analog Hot Swap Controllers UCC3916DP

The UCC3916DP is a hot swap controller designed for SCSI applications, providing integrated power management and circuit breaker functionality. It features an integrated power FET with a nominal on-resistance of 220m,Ѷ, allowing for efficient current handling. The device has a trip current set at 1.65A and a maximum current limit of 2A, ensuring reliable operation under specified conditions. The UCC3916DP operates with a supply voltage range of 4V to 6V and includes a programmable fault timer, which can be set using an external capacitor. It supports a fixed 3% duty cycle during fault conditions, enhancing system reliability. The controller also incorporates thermal shutdown protection and can enter a low-power sleep mode, drawing only 1µA when disabled. This component is packaged in an 8-pin SOIC format, making it suitable for compact designs. Its compliance with SCSI standards ensures compatibility with various SCSI devices, making it a viable option for engineers looking to implement hot swap capabilities in their projects.
