Hot Swap Controller 1 Channel General Purpose 23-LQFN-CLIP (6x5)
The TPS16851VMAR is an automotive-grade integrated electronic fuse device designed to provide advanced power path protection and monitoring for low-voltage DC power distribution systems. The device integrates multiple protection mechanisms including overvoltage protection, undervoltage protection, overcurrent protection, reverse current blocking, and inrush current control within a compact package optimized for space-constrained applications. It is intended for use in automotive, industrial, and embedded electronic systems requiring robust hot-swap capability, fault isolation, and controlled power sequencing.
The device incorporates precision current sensing and programmable fault management functions that enable reliable protection of downstream circuitry against abnormal operating conditions. Adjustable protection thresholds and timing parameters allow flexible system-level configuration while maintaining fast fault response and high reliability. Integrated MOSFET control minimizes external component count and simplifies PCB implementation.
The TPS16851VMAR supports wide input operating ranges suitable for automotive battery-powered environments and transient-prone supply rails. The device is qualified for harsh operating conditions and includes thermal shutdown and fault reporting features to improve system safety and diagnostics.
