Product details
Overview
TPS16530RGER from Texas Instruments is a 58-V, 4.5-A industrial eFuse with integrated 31-mΩ Hot-Swap FET, ±7% adjustable current limit (0.6–4.5 A), 2× pulse current support for transient loads, and thermal regulation during inrush. It delivers precise load protection in telecom power amplifiers, medical equipment, fire alarm panels, and industrial printers.
For engineers reviewing the TPS16530RGER datasheet, TPS16530RGER pinout, TPS16530RGER application, or TPS16530RGER equivalent, this page provides verified package mapping (24-pin VQFN, 4.00 mm × 4.00 mm), confirmed pin functions including IMON (±6% analog current monitor), PGOOD, MODE, dVdT, and SHDN, plus real-world timing specs such as 1 µs fast-trip response and 25.5 ms pulse current timeout.
Technical Context
The TPS16530RGER implements dual-stage overcurrent protection: a programmable current-limit amplifier (±7% accuracy) for sustained overload and a dedicated fast-trip comparator (45-A threshold, 1-µs response) for hard shorts. Its thermal regulation loop actively controls junction temperature at 145°C (typical) during capacitive load charging, enforcing a 1.3-s timeout to prevent thermal runaway.
It supports two fault-handling modes via the MODE pin: latch-off for safety-critical systems or auto-retry for resilient power-up sequences. The dVdT pin enables slew-rate control through an external capacitor, while UVLO (±2% accuracy) and EN/SHDN pins provide coordinated system-level enable, shutdown, and brown-out supervision without external supervisors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5 V to 58 V input range; supports 56-V IPC9592B clearance in 20-pin HTSSOP (RGE package uses same voltage rating) |
| RON | 30.44 mΩ typical (25°C); enables <1.4 W conduction loss at 4.5 A, reducing thermal stress in high-current paths |
| Current Limit Range | 0.6 A to 4.5 A (±7%); set by ILIM resistor (4.02–30 kΩ), enabling precise matching to downstream load requirements |
| Pulse Current Support | 2× IOL for ≤25.5 ms; allows brief 9-A transients (e.g., motor startup, capacitor charging) without fault assertion |
| Quiescent Current | 21 µA in shutdown; minimizes standby power draw in always-on industrial systems |
| Thermal Regulation | Active 145°C (typical) regulation with 1.3-s timeout; prevents thermal damage during hot-plug into large capacitive loads |
| Fast-Trip Response | 1 µs turnoff at 45-A short-circuit current; isolates faults before PCB trace fusing or connector arcing occurs |
Pinout & Package
TPS16530RGER is housed in a 24-pin VQFN package (RGE) with 4.00 mm × 4.00 mm body size and exposed PowerPAD™ thermally connected to GND. The package supports IPC9592B clearance for 56-V operation and achieves RθJA = 32.1°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN / P_IN | Power Input / Device Supply | Connects directly to internal FET drain; P_IN must be tied to IN for proper biasing of internal circuitry |
| OUT | Power Output | Source terminal of internal FET; delivers regulated output with controlled slew rate and current limiting |
| dVdT | Slew Rate Control | Capacitor-to-GND sets output ramp time; floating enables fast charge (350–700 µs for 10–90% VOUT) |
| ILIM | Current Limit Programming | Resistor-to-GND sets IOL; open/short detection disables FET until fault is cleared |
| MODE | Fault Response Selection | Open = latch-off; grounded = auto-retry; determines system recovery behavior after overcurrent or thermal fault |
| SHDN | Low-Power Shutdown | Active-low input; pulls device into 21-µA shutdown state and resets latched faults when cycled |
| IMON | Analog Current Monitor | Sources 27.9 µA/A (±6%) scaled current; converts to voltage with external resistor for real-time load health monitoring |
| PGOOD | Power Status Indicator | Active-high open-drain output; signals FET enhancement and enables downstream DC-DC converters only when stable |
| FLT | Fault Event Flag | Active-low open-drain output; asserts for UVLO, overcurrent, thermal shutdown, or ILIM faults; de-glitched with 1.3-ms delay |
| UVLO | Undervoltage Threshold Input | Resistor-divider sets ±2% accurate cutoff; hysteresis prevents chatter during brown-out recovery |
| EN | Enable Control | Active-low logic input; allows MCU coordination of power sequencing; must not float |
| GND | System Ground Reference | Reference for all analog and digital functions; PowerPAD™ must be soldered to GND plane for thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Inrush Control | External dVdT capacitor enables precise output voltage ramp rate-critical for preventing backplane sag during hot-plug insertion |
| Two-Stage Overcurrent Protection | Combines ±7% accurate current limit (for sustained overload) with 1-µs fast-trip (for catastrophic shorts), eliminating need for redundant protection layers |
| Thermal Regulation with Timeout | Automatically throttles inrush current to hold TJ at 145°C and enforces 1.3-s max duration-prevents thermal damage during unknown capacitive loads |
| Configurable Fault Recovery | MODE pin selects between latch-off (safe isolation) and auto-retry (resilient restart), adapting to system safety vs. availability requirements |
| Integrated Supervision Functions | ±2% UVLO, ±6% IMON, and PGOOD eliminate discrete supervisors-reducing BOM count and layout area in space-constrained designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS26630RGER | Same 58-V max, but fixed 4.5-A current limit (no ILIM adjustment); lacks 2× pulse current support and thermal regulation loop | Best for cost-sensitive, static-load applications where transient surge handling is unnecessary | Select TPS26630RGER only if adjustable current limit, pulse support, and thermal regulation are not required |
| LT4295IMS#PBF | 60-V rating, 4.7-A limit, ±5% accuracy; includes I²C interface for telemetry but no analog IMON output or dVdT control | Suitable for digitally managed PDUs requiring remote monitoring, not analog feedback or simple slew control | Choose LT4295IMS#PBF when system-level telemetry and configurability outweigh need for analog simplicity and inrush tuning |
Compared with TPS16530RGER, TPS26630RGER offers lower BOM cost but forfeits critical transient resilience and thermal intelligence, while LT4295IMS#PBF adds digital complexity at the expense of analog design flexibility and direct inrush control-making TPS16530RGER optimal for robust, analog-centric industrial power protection.

FAQ
What is the maximum continuous current rating of the TPS16530RGER?
The TPS16530RGER supports a continuous current limit of up to 4.5 A, adjustable via the ILIM pin resistor (4.02 kΩ yields 4.5 A ±7%). Its 31-mΩ RON ensures low conduction losses-under 1.4 W at full load-enabling reliable operation within thermal limits at ambient temperatures up to +125°C when properly heatsinked via the PowerPAD™.
How does the TPS16530RGER handle short-circuit events?
The TPS16530RGER employs a dual-protection architecture: a fast-trip comparator triggers FET turnoff in 1 µs when output current exceeds 45 A, preventing destructive energy dissipation. For softer overloads (e.g., 2× IOL), it enters timed current limiting (25.5 ms max), then either recovers or shuts down based on MODE pin configuration-ensuring both speed and system-level fault management.
Can the TPS16530RGER be used with large output capacitors?
Yes-the TPS16530RGER includes a dedicated thermal regulation loop that dynamically controls inrush current to maintain junction temperature at ~145°C during startup into large capacitive loads. With a 1.3-s timeout, it safely charges multi-millifarad banks (e.g., 4.7 mF) without thermal shutdown, provided the dVdT pin is configured per design guidelines in the datasheet.
What is the function of the MODE pin on the TPS16530RGER?
The MODE pin configures fault recovery behavior: open circuit selects latch-off mode (FET remains off until reset via SHDN), while grounding selects auto-retry mode (device attempts restart after fault clears). This allows designers to align protection strategy with system safety requirements-e.g., latch-off for fire alarm panels, auto-retry for industrial printers needing minimal downtime.
Does the TPS16530RGER support undervoltage lockout, and how is it configured?
Yes-the TPS16530RGER features ±2% accurate adjustable UVLO via the UVLO pin. A resistor divider from IN to GND sets the threshold; for example, R1 = 100 kΩ and R2 = 10 kΩ yields ~12 V cutoff. If unused, UVLO must be tied to IN-not left floating-to ensure stable operation and avoid false fault assertions during brown-out conditions.
