TPS16630PWPR - 60V 6A eFuse with Adjustable PLIM | TI HTSSOP-20
MPN: TPS16630PWPR ✓ Hoạt độngTPS16630PWPR Tóm tắt
An eFuse (electronic fuse) is a solid-state circuit-protection device that replaces a traditional fusible link or PTC. Compared with a one-shot fuse, an eFuse can auto-retry or latch off, log faults, and offer precise, programmable thresholds. eFuses sit within the broader category of hot-swap controllers and power-path protection ICs, which in turn belong to the power-management IC family. PLIM adds a programmable output-power clamp on top of the current limit, allowing designers to cap inrush energy in capacitive loads and protect upstream sources from sustained over-power events.
Key features of the TPS16630PWPR include: integrated 31 mΩ Rds(on) FET; 0.6 A to 6 A adjustable ILIM (±7%); 4.5 V to 60 V operating VIN; fast short-circuit response with circuit-breaker mode; output slew-rate control via dV/dT pin; adjustable UVLO and overvoltage lockout (OVLO); MODE pin for latch-off or auto-retry selection; fault flag (FLG) output; thermal shutdown; and a -40°C to +125°C junction-temperature operating range. The HTSSOP-20 PowerPAD package exposes a thermal pad that drops θJA to roughly 28 °C/W when properly soldered, supporting 6 A continuous current at modest VIN-VOUT deltas.
Architecturally, the device uses an N-channel MOSFET controlled by an internal charge pump, an analog control loop for current and power limiting, and a fault-management state machine. The PLIM block multiplies sensed input voltage by load current and compares it against an external resistor-set reference, producing a power ceiling independent of load impedance. This approach allows tighter protection in applications where current alone is not enough to characterize stress on the source.
Typical applications include 24-V industrial PLC I/O rails, factory-automation sensors, USB-PD source protection in 12-V/24-V adapters, server-board auxiliary rails, and automotive body-electronics loads operating on 12-V/24-V battery systems. Designers reach for the TPS16630PWPR when discrete hot-swap controllers plus external FETs become too large or too expensive for the BOM.
When designing with this part, choose the ILIM resistor using RILIM = 12 kΩ × 6 A / ILIM and verify inrush energy stays within the SOA of the input source. The PowerPAD must be soldered to a copper area of at least 1 in² for the thermal performance quoted in the datasheet, and decoupling capacitors should be placed within 2 mm of IN and OUT pins to keep high-di/dt transients out of the control loop.

Ứng dụng tiêu biểu
TPS16630PWPR phù hợp cho 7 Áp dụngs: 24V Industrial PLC I/O Power Rail Protection, USB-PD and 12V/24V Adapter Source Protection, Server Board Auxiliary and Peripheral Rails, Automotive 12V/24V Body Electronics Loads, Factory Automation Sensor and Actuator Power, Battery Management System Protection FET Replacement, LED Lighting Driver Input Protection.
24V Industrial PLC I/O Power Rail Protection
The TPS16630PWPR is well suited for protecting 24 V industrial PLC digital outputs and sensor supply rails because its 60 V VIN rating easily covers 24 V nominal plus ±20% surges per IEC 61131-2. The integrated 31 mΩ FET drops less than 200 mV at 6 A, leaving headroom for downstream regulation. Designers typically use the PLIM feature to cap inrush on long cable runs and large capacitive loads, preventing nuisance trips during PLC module hot-swap. The latch-off / auto-retry MODE pin lets the controller either hold a fault for service or recover automatically after the surge clears.

USB-PD and 12V/24V Adapter Source Protection
USB-PD source designs using 12 V or 24 V adapters benefit from the TPS16630PWPR's combination of PLIM and fast short-circuit response. PLIM sets an output-power ceiling that limits inrush energy when a downstream device requests high-current negotiation, preventing the upstream adapter from going into current limit. The dV/dT pin controls output slew rate to satisfy USB-PD attach timing while the FLG pin feeds the controller for fault reporting. Compared with a fuse plus TVS, the TPS16630PWPR is smaller, programmable, and resettable.

Server Board Auxiliary and Peripheral Rails
Server motherboards distribute 12 V auxiliary rails to peripherals, fans, and storage backplanes where hot-plug events can create large inrush transients. The TPS16630PWPR handles these events with its adjustable ILIM and PLIM, while the integrated FET removes the need for a discrete hot-swap controller and external MOSFET. The FLG output can drive a BMC GPIO for fault logging. Thermal performance of the HTSSOP-20 PowerPAD supports 6 A continuous at moderate airflow, making it a fit for 1U and 2U server chassis.

Automotive 12V/24V Body Electronics Loads
Body-electronics modules such as seat controllers, mirror adjusters, and lighting drivers operate on 12 V or 24 V battery feeds with frequent load-dump and cranking transients. The TPS16630PWPR's 60 V absolute-maximum rating tolerates load-dump pulses up to the ISO 7637-2 limits when paired with an external TVS, and its -40 °C to +125 °C TJ range covers underhood and cabin environments. PLIM helps limit total inrush when multiple loads are activated simultaneously, reducing stress on the upstream wiring harness.

Factory Automation Sensor and Actuator Power
Field-mounted sensors and actuators on 24 V factory buses are subject to short circuits from cable damage and connector failures. The TPS16630PWPR's fast short-circuit response isolates the fault within microseconds, and the MODE pin configurable latch-off lets maintenance staff diagnose the failed branch instead of the part repeatedly retrying. PLIM also clamps sustained over-power events caused by failing motors or stuck actuators, protecting the central 24 V supply from collapse. The HTSSOP-20 PowerPAD package enables compact IP67-rated field-mount housings.
Được đề xuất
Battery Management System Protection FET Replacement
Some low-voltage battery management systems replace a discrete reverse-blocking FET pair with an eFuse to gain programmable disconnect behavior. The TPS16630PWPR can be used as the high-side disconnect element in 12 V/24 V battery packs, where its OVLO protects against charger overvoltage and PLIM prevents excessive charge current during fault conditions. Designers should verify that quiescent current during latch-off is acceptable for long-term storage; the FLG output can drive an LED or fuel-gauge interrupt pin.
Được đề xuất
LED Lighting Driver Input Protection
High-bay and outdoor LED luminaires often accept 24 V to 48 V input and benefit from eFuse protection against field wiring shorts and lightning-induced surges. The TPS16630PWPR's PLIM caps inrush when large driver-bus capacitors charge at cold temperatures, while its OVLO rejects sustained overvoltage from failing drivers upstream. Compared with a fuse, the auto-retry MODE reduces maintenance truck rolls in inaccessible installations, and the integrated FET reduces BOM cost versus a discrete hot-swap solution.

Ghi chú thiết kế
Estimated: at VIN = 24 V, VOUT = 12 V, and 6 A continuous load, the integrated 31 mΩ FET dissipates roughly 6 V × 6 A × (31 mΩ / 24 V × Vbus_collapse) plus any excess drop across the FET. With the PowerPAD soldered to at least 1 in² of 2 oz copper, expect θJA around 28 °C/W; at 6 A the die rise over ambient is then on the order of 20-25 °C. Provide copper pours on both top and bottom layers stitched with thermal vias for best heat transfer. If continuous load is 6 A and ambient exceeds 70 °C, derate to 5 A or improve airflow.
Place the input bulk capacitor (≥1 µF X7R) within 2 mm of the IN pins and the output capacitor (≥1 µF X7R plus optional bulk electrolytic) within 2 mm of the OUT pins. The PGND and AGND pins should connect to a single ground plane, with power-return current kept away from the analog ground island. Keep the ILIM and PLIM resistor traces short and direct; these are high-impedance nodes sensitive to leakage and noise. Use a star-ground topology around the AGND pin if the rest of the board has noisy return currents.
Do not leave the dV/dT pin floating - even a small parasitic capacitance on a floating dV/dT pin can cause unpredictable inrush behavior. Use a 1 nF to 100 nF X7R capacitor as a starting point and adjust to control turn-on time. The MODE pin must be tied high (auto-retry) or low (latch-off) and not left floating. PLIM must be enabled with a valid resistor; tying PLIM to GND disables power limiting and can allow sustained over-power events. The FLG output is open-drain and requires an external pull-up to logic high.
Wide copper pours on IN and OUT traces are essential to keep the parasitic inductance low; with 6 A load a 100 nH of trace inductance creates roughly 1 V of ringing during a fast short-circuit event. Stitch the input and output ground returns with multiple vias near the PowerPAD to provide a low-impedance thermal and electrical path. Keep the analog ground island small and routed only to the AGND pin. If the board has a noisy switching converter nearby, add a small RC filter on the EN pin to prevent false enables.
