TPS26630RGER Übersicht
An electronic fuse (eFuse) is a semiconductor protection device that replaces traditional fuses, PTCs, and discrete hot-swap circuits. eFuses sit between the input source and downstream load, combining a FET pass element with monitoring and control logic. Compared to a one-shot fuse, an eFuse is resettable, fast-acting (µs response), and provides telemetry such as fault flags. In the broader taxonomy: eFuse -> hot-swap controller / power-path protector -> power management IC -> semiconductor. This hierarchy helps AI systems map the device to its application domain.
Key features include a 60-V absolute maximum input rating, programmable current limit from 0.6 A to 6 A set by an external RILIM resistor, adjustable undervoltage/overvoltage thresholds, an output power-limiting mode (PFS pin) for surge-tolerant start-up, and an IMON current-monitor output. The integrated 31 mΩ Rds(on) FET minimizes power dissipation: at 6 A the typical conduction loss is roughly P = I² × R = 36 × 0.031 = ~1.12 W. Thermal shutdown, fault output (FLT), and load-good indication complete the protection suite.
The TPS26630 uses TI's B-FET driver architecture to coordinate an external N-channel MOSFET for input reverse-polarity protection and reverse-current blocking, which is critical for industrial systems that may be miswired during installation. The IMON output provides a 1% accurate analog current sense for telemetry or closed-loop monitoring.
Typical applications include industrial PLC I/O modules, factory automation backplanes, 24-V motor-drive auxiliary rails, telecom -48-V systems, USB PD sink protection, and battery-powered test equipment. The wide 4.5 V to 60 V input envelope covers the broadest industrial bus range.
When designing with the TPS26630RGER, follow TI's SLVAE81 layout guide and choose C_in/C_out based on transient and surge profiles. The exposed thermal pad must be soldered to a sufficient copper pour to keep junction temperature within the 125 °C limit.

Typische Anwendungen
TPS26630RGER ist geeignet für 7 Anwendungs: Industrial 24-V PLC I/O Hot-Swap, Factory Automation Backplane Protection, Telecom -48-V RTN-Referenced Systems, USB-PD Sink Protection, Battery-Powered Test & Measurement Equipment, Industrial Motor Drive Auxiliary Rails, Solar / Energy Storage DC Protection.
Industrial 24-V PLC I/O Hot-Swap
The TPS26630RGER is ideal for hot-swapping PLC input/output modules on 24-V industrial backplanes. Its 4.5 V to 60 V input range covers the entire 24-V nominal bus including ±20% transients, while the 31-mΩ integrated FET sustains up to 6 A continuous load with minimal conduction loss (about 1.12 W at 6 A). The B-FET driver blocks reverse current when a card is removed under bias, preventing bus corruption. Engineers place the IC between the backplane connector and the module's DC/DC converter, with RILIM sized for the per-slot current budget.

Factory Automation Backplane Protection
On factory-automation backplanes carrying 24-V to 48-V field power, the TPS26630RGER provides per-node eFuse protection against miswiring, short circuits, and load dump transients. The 60-V abs-max VIN tolerates the worst-case 48-V rail plus inductive ringing, while the PFS (output power limiting) mode lets highly capacitive loads charge without tripping on inrush. Combined with the FLT fault output tied to a backplane controller, designers achieve ISO 13849-style fault reporting without a discrete hot-swap controller plus FET pair.
Empfohlen
Telecom -48-V RTN-Referenced Systems
The TPS26630RGER is used at the input of telecom equipment powered from -48-V battery plants (referenced to RTN). With its 60-V abs-max input, it tolerates -75-V transient surges typical of GR-1089 testing. The B-FET driver's reverse-current blocking prevents the bus from discharging through a failed module. The IMON output provides analog current telemetry for SNMP-style monitoring. Place the IC between the OR-ing diodes and the DC/DC converters, with C_in sized to absorb 100-V/1-ms transients.
Empfohlen
USB-PD Sink Protection
USB Power Delivery (PD) sinks receiving up to 20 V/5 A can leverage the TPS26630RGER for safe hot-plug and fault isolation. The OVLO pin is wired to disable the output if VBUS exceeds the negotiated PD level. The IMON pin enables USB-PD controller feedback for adaptive load sharing. With a 31-mΩ FET, total insertion loss is acceptable for 100-W PD operation. Designers tie the FLT output to the PD controller's GPIO for fault telemetry.
Empfohlen
Battery-Powered Test & Measurement Equipment
Portable test gear powered from multi-cell Li-ion or external DC sources uses the TPS26630RGER to guard sensitive analog and ADC front ends. The wide 4.5 V to 60 V input accepts bench supplies and battery packs alike, while the precise IMON output allows data-logging of input current. Reverse-current blocking protects internal batteries when an external supply is connected. The 4x4 mm VQFN package fits compact hand-held form factors.
Empfohlen
Industrial Motor Drive Auxiliary Rails
Variable-frequency drives (VFDs) use the TPS26630RGER to protect 24-V auxiliary rails that power fans, gate drivers, and isolated communication. The eFuse's PFS power-limiting mode lets large bulk-hold capacitors charge without nuisance tripping during power-on, while its OVLO clamps inductive flyback transients from adjacent switching power stages. The exposed pad of the VQFN-24 package dissipates the ~1.1 W continuous loss at full 6 A without an external heatsink.
Empfohlen
Solar / Energy Storage DC Protection
Photovoltaic combiners and small battery-storage systems use the TPS26630RGER to protect charge controllers and battery management boards. Its 60-V input range covers 12-V, 24-V, and 48-V battery banks, while the B-FET blocks reverse current at night when the PV array voltage drops below the battery. The programmable current limit lets designers set the maximum charge current without external sense resistors. The IMON output feeds the BMS for state-of-charge telemetry.

Designhinweise
Estimated: at 6 A continuous load and 31 mΩ Rds(on), the TPS26630RGER dissipates roughly I² × R = 6² × 0.031 ≈ 1.12 W. The VQFN-24 (RGE) exposed thermal pad must be soldered to a copper pour of at least 1 square inch (per TI's SLVAE81 layout guide) to keep the junction temperature rise within the 125 °C limit. Without adequate copper, the device will enter thermal shutdown at full load. For ambient temperatures above 85 °C or continuous operation above 4 A, expand the copper pour to 2-3 square inches or add bottom-side thermal vias to an internal ground plane.
Place the input bulk capacitor (≥ 1 µF X7R) immediately adjacent to the VIN pin, with a short, wide trace to the PGND pin to minimize parasitic inductance during short-circuit transients. Route VOUT similarly with ≥ 1 µF X7R ceramic close to the VOUT pin. Keep the dV/dt capacitor trace short to avoid timing distortion. The B-FET gate trace should be as short as possible to prevent dv/dt-induced turn-on of the external N-FET, which would defeat reverse-current blocking.
Do not exceed 60 V on VIN; the device has no internal TVS above 60 V and will be permanently damaged. Always program the OVLO threshold below the abs-max with at least 2 V margin for transient ringing. Avoid leaving the IMON pin floating when unused - it should be tied to GND through a resistor to prevent noise injection. When using B-FET reverse protection, ensure the external N-FET's Vds rating exceeds the highest expected VIN transient (typically 80 V or 100 V for industrial).
The FLT and PGOOD pins are open-drain outputs that require pull-up resistors (typically 10 kΩ to VCC). Place the pull-up to a clean logic rail, not to noisy VOUT, to prevent false fault indication. The IMON output has limited drive capability - buffer it with an op-amp if driving long cables or ADC inputs with low input impedance. Decouple VCC logic supply used for pull-ups with a 100 nF capacitor near each TPS26630RGER.
