# TPS16850VMAR (Component) ## Description Hot Swap Controller 1 Channel General Purpose 23-LQFN-CLIP (6x5) The TPS16850VMAR is an automotive-grade integrated hot-swap and protection controller designed for robust power-path management in low-voltage DC systems. The device provides comprehensive protection features including overvoltage protection, undervoltage protection, reverse current blocking, inrush current control, overcurrent protection, and short-circuit protection. It is intended for applications requiring controlled power delivery and fault isolation in harsh electrical environments. The device integrates dual back-to-back MOSFET control to support bidirectional current blocking and safe power switching. Adjustable protection thresholds and timing parameters allow flexible system configuration for various power rail requirements. The TPS16850VMAR supports operation across a wide supply voltage range and is optimized for automotive and industrial systems requiring high reliability and transient immunity. The controller includes fault reporting and system status monitoring functions to support intelligent power management architectures. Soft-start capability minimizes inrush current during startup, reducing stress on connectors, power supplies, and downstream circuitry. Integrated thermal protection enhances system safety during abnormal operating conditions. The TPS16850VMAR is qualified for automotive applications and complies with AEC-Q100 requirements. The device is provided in a compact VQFN package suitable for space-constrained designs and high-density PCB layouts.
