Product details
Overview
TPS16632RGER from Texas Instruments is a 60V, 6A industrial eFuse with integrated 31mΩ hot-swap FET, adjustable current limit (0.6–6A ±7%), fixed 39V overvoltage clamp, and adjustable output power limiting (PLIM) for IEC61010-1/UL1310 compliance. It delivers precise analog current monitoring (±6%), programmable slew rate control via dVdT pin, and thermal regulation during inrush into large capacitive loads - used in PLC I/O modules and motor drive encoder supplies.
For engineers reviewing the TPS16632RGER datasheet, TPS16632RGER pinout, TPS16632RGER application, or TPS16632RGER equivalent, key selection considerations include its 24-pin VQFN package, ±2% UVLO/OVP accuracy, PGOOD signaling for DC/DC enable control, and MODE-configurable latch-off vs auto-retry fault response under overload, power limit, or thermal events.
Technical Context
The TPS16632RGER implements a precision current-sense amplifier feeding dual comparators for fast-trip (1µs) short-circuit protection and programmable overload limiting. Its PLIM circuitry uses a dedicated input (PLIM pin) sourcing 5.02µA to set output power limit between 94W and 160W via external resistor, with ±6% accuracy across temperature.
Thermal regulation operates at 145°C (typical), enforcing automatic inrush current reduction when junction temperature approaches TJ_REG; if regulation persists beyond 1.25s (typical), the device shuts down - behavior modulated by MODE pin configuration for latch-off or auto-retry recovery after thermal timeout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5V to 60V input range; supports industrial 48V DC systems and withstands 67V absolute max transients. |
| RON | 30.44mΩ typical (25°C); enables <1.8W conduction loss at 6A, critical for high-efficiency hot-swap applications. |
| Current Limit Accuracy | ±7% over 0.6–6A range; reduces input supply overdesign margin while ensuring reliable load protection. |
| Output Power Limit (PLIM) | Adjustable 94–160W (±6%); replaces discrete power-limiting circuits and simplifies compliance with UL1310 Class 2 and IEC61010-1 energy-limited requirements. |
| Overvoltage Clamp | Fixed 39V maximum (TPS16632 only); protects downstream 3.3V/5V/12V rails without external clamping components. |
| Quiescent Current | 21µA in shutdown; enables low-power system standby modes without compromising protection readiness. |
| PGOOD Delay | 11.5ms deglitch time (rising/falling); prevents false enable/disable of downstream converters during transient disturbances. |
Pinout & Package
TPS16632RGER is housed in a thermally enhanced 4mm × 4mm, 24-pin VQFN (RGE) package with exposed PowerPAD™ connected to GND for heat sinking. Pin count and layout match TPS16630/TPS16637 RGE variants but include PLIM functionality absent in TPS16630.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN / OUT | Power path terminals | IN connects to internal FET drain; OUT is source terminal - defines 31mΩ bidirectional conduction path with thermal derating up to 125°C ambient. |
| PLIM | Power limit programming input | Sinks 5.02µA; resistor to GND sets output power limit (e.g., 100kΩ = 100W); floating disables PLIM function. |
| ILIM | Current limit programming input | Sinks current to set overload threshold; 3kΩ yields 6A ±7%, enabling precise coordination with downstream fuse ratings. |
| dVdT | Output slew rate control | Capacitor to GND sets ramp time (e.g., 22nF → 8.35ms 10–90% rise); open-circuit enables fastest charge (350–700µs). |
| MODE | Fault response selector | Open = latch-off on fault; grounded = auto-retry - determines system recovery behavior after thermal, current, or power limit events. |
| IMON | Analog current monitor output | Sources 27.9µA/A (±6%) - converts load current to voltage via external resistor for real-time health monitoring. |
| PGOOD | Power status indicator | Active-high open-drain output; asserts when FET is fully enhanced and OUT voltage reaches regulation - used to enable downstream DC/DC converters. |
| SHDN | Enable/disable control | Pull low to enter 21µA shutdown; toggling resets latched faults - provides MCU-level sequencing and power-state control. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable Output Power Limiting (PLIM) | Enables single-chip compliance with IEC61010-1 energy-limited circuit requirements without external power-sensing circuitry. |
| Fixed 39V Overvoltage Clamp | Eliminates need for external TVS diodes on 24V/48V industrial buses, reducing BOM count and board area. |
| Thermal Regulation Loop | Automatically throttles inrush current during hot-plug into large capacitive loads (e.g., 1000µF), preventing thermal runaway without user intervention. |
| ±2% UVLO/OVP Threshold Accuracy | Replaces discrete supervisor ICs - tight tolerance ensures reliable brown-out detection and overvoltage shutdown without calibration. |
| 1µs Fast-Trip Short-Circuit Response | Isolates faulty loads before PCB traces or connectors sustain damage, meeting industrial safety standards for fault containment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar eFuse applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS16630RGER | Lacks PLIM and fixed OVP clamp; offers adjustable OVP cutoff instead; same 24-pin VQFN package and RON. | Used where power limiting is unnecessary but adjustable overvoltage cutoff (e.g., 45V) is required for custom bus protection. | Select TPS16630RGER only if PLIM is not needed and OVP threshold must be programmable above 39V. |
| TPS26632RGER | Lower 36V max rating; includes integrated reverse polarity protection; identical PLIM, IMON, and MODE functionality. | Targeted at 24V automotive/transportation systems requiring reverse-battery immunity - not rated for 48V/60V industrial use. | Choose TPS26632RGER only for 12–24V applications needing reverse-voltage blocking; unsuitable for 48V+ industrial rails. |
Compared with TPS16630RGER, TPS16632RGER adds mandatory PLIM and fixed 39V clamp for safety-compliant designs, while TPS26632RGER trades voltage rating for reverse-polarity protection - making TPS16632RGER the sole choice for 48V/60V industrial systems requiring both power limiting and overvoltage clamping.

FAQ
What is the maximum continuous output current supported by the TPS16632RGER?
The TPS16632RGER supports a continuous output current up to 6A, with RON specified at 30.44mΩ (typical) at 25°C. Derating applies above 85°C ambient due to thermal resistance (RθJA = 31.4°C/W); full 6A operation requires adequate PCB copper area and airflow to maintain junction temperature ≤125°C.
How does the PLIM (Power Limit) function work on the TPS16632RGER?
The TPS16632RGER uses the PLIM pin to set output power limit by connecting an external resistor to GND; the device sources 5.02µA, yielding 100W with 100kΩ. This feature actively limits POUT = VOUT × IOUT to prevent hazardous energy release - critical for UL1310 Class 2 and IEC61010-1 compliance.
Can the TPS16632RGER replace a mechanical fuse in industrial equipment?
Yes - the TPS16632RGER functions as an electronic circuit breaker with programmable 0.6–6A current limit, 1µs short-circuit response, and latch-off/auto-retry fault handling. Unlike mechanical fuses, it provides diagnostic outputs (IMON, FLT, PGOOD) and eliminates manual replacement, supporting predictive maintenance in PLC and DCS systems.
What is the purpose of the dVdT pin on the TPS16632RGER?
The dVdT pin on the TPS16632RGER controls output voltage slew rate during power-up: a capacitor from dVdT to GND sets ramp time (e.g., 22nF → 8.35ms), limiting inrush into large capacitive loads. Leaving dVdT open enables fastest charge (350–700µs), useful for known small loads where thermal regulation is unnecessary.
Does the TPS16632RGER support functional safety certification?
Yes - the TPS16632RGER is functional safety-capable, with documentation available to support ISO 13849 and IEC 61508 system-level design. It includes diagnostic features like IMON current monitoring, PGOOD status signaling, and fault flag assertion, enabling safe torque off (STO) and safe stop architectures in industrial motion control.
