TPS26622DRCR

Current Regulation/Management Overview

The TPS26622DRCR is a single-channel hot-swap voltage controller manufactured by Texas Instruments, designed for industrial applications. It operates within an input voltage range of 4.5 V to 60 V and supports a maximum output current of 880 mA. The device features an on-resistance of 478 mΩ and a typical quiescent current of 343 µA. It is housed in a compact 10-pin VSON package with dimensions of 3 mm x 3 mm. The component functions as an electronic fuse (eFuse) with integrated power-fail detection capabilities. It supports operation across an extended temperature range from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrated reverse polarity protection ensures system safety during incorrect power connections.
• Power-fail detection capability allows the controller to signal upstream systems when output voltage drops below valid thresholds.
• Hot-swap functionality enables safe insertion and removal of load modules without disrupting the main power bus.

Current Regulation/Management Applications

• Industrial backplane power distribution
• PCI/PCIe peripheral power management
• Telecommunications equipment power rails

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DRCR' corresponds to the standard tape-and-reel packaging configuration intended for automated assembly processes. Confirm that the ordering part number matches the exact voltage and current ratings required for the target circuit design. Ensure compatibility with the 10-VSON footprint on the printed circuit board layout. Check for any regional compliance certifications relevant to the deployment environment.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with high-voltage tolerance up to 60 V is required. The low on-resistance minimizes conduction losses compared to discrete MOSFET implementations. Consider the thermal performance of the exposed pad in the VSON package for heat dissipation requirements. Evaluate the need for remote enable control if system-level shutdown coordination is necessary.

Current Regulation/Management Part Context

This device belongs to the TPS2662x family of eFuses from Texas Instruments. It shares functional similarities with models like the TPS26620 and TPS26621 but may differ in specific threshold settings or feature sets. The family is designed to replace traditional fuses and discrete protection circuits in space-constrained industrial designs.

Current Regulation/Management Replacement Considerations

The TPS26621DRCR is a confirmed substitute within the same series offering similar protection features. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Other variants in the TPS2662x family may require schematic adjustments due to differing control logic or threshold values.
