VNS1NV04D13TR Descripción general
An OMNIFET II (OMNI-purpose MOSFET, second generation) is a fully protected, self-contained intelligent low-side power switch that combines the low-loss advantages of a power MOSFET with the diagnostic and protection features traditionally implemented externally. OMNIFET II devices sit within the broader category of power distribution switches, which themselves belong to the power management IC family used to drive relays, solenoids, lamps, and resistive or inductive loads in 12V and 24V systems.
Key differentiating features include extremely low current draw from the logic-level input pin, automatic over-temperature and over-voltage shutdown with auto-restart, a status feedback pin that can sink current when a fault condition is detected, and a compact SO-8 footprint that allows two protected switches in the same board area previously required for a single discrete MOSFET plus protection circuitry. The active clamp absorbs inductive kickback when switching off coils, removing the need for an external freewheeling diode in most applications.
The device is built on STMicroelectronics' proprietary OMNIFET II process, which co-integrates a vertical DMOS output stage with CMOS-compatible analog protection and logic blocks on the same silicon die. This co-integration eliminates parasitic wiring inductance between the MOSFET and its protection circuits, enabling faster fault response times than discrete solutions. The 3V to 5V CMOS-compatible input thresholds allow direct connection to microcontroller GPIO pins without level shifters.
Typical applications include automotive body electronics such as door lock actuators, seat control motors, and lamp drivers; industrial PLC discrete outputs; relay and solenoid drivers; and any 12V/24V load-driving circuit that requires per-channel fault diagnostics. The dual-channel configuration is particularly valuable in space-constrained designs that previously required two separate protected switches.
When designing with this part, ensure that the high-side of the load connects to the battery/supply rail and the low-side returns through the device's drain pin. Decouple the supply close to the source pins, and route the drain traces with adequate copper area to handle the 1.7A continuous current without exceeding the SO-8 thermal limits (typically a 2-ounce copper pour of at least 100 mm^2 per channel).

Aplicaciones típicas
VNS1NV04D13TR es adecuado para 6 aplicacións: Automotive Body Electronics, Relay and Solenoid Driver, Lamp and LED Driver (12V/24V), Industrial PLC Discrete Output Module, DC Motor Driver (Small Brushed), Battery-Powered Load Switch.
Automotive Body Electronics
The VNS1NV04D13TR's 40V drain clamp and integrated active clamp make it well suited for driving 12V automotive body loads such as door lock actuators, seat motors, mirror adjusters, and liftgate latches. Each channel's 1.7A continuous current handles typical relay coils and small DC motors, while the 250 mOhm RDS(on) limits conduction loss to about 0.72W per channel at full load. The on-die thermal shutdown protects against stall-current conditions in motor loads, and the active clamp eliminates the need for external freewheeling diodes when switching inductive loads. The status feedback pin connects to an MCU interrupt to detect open-circuit or short-circuit faults during end-of-line testing, reducing warranty returns.
Recomendado
Relay and Solenoid Driver
Each channel of the VNS1NV04D13TR can directly drive an automotive or industrial relay coil from a 3.3V or 5V MCU GPIO, replacing discrete MOSFET-plus-protection circuits with a single SO-8 IC. The 40V drain rating handles 12V and 24V coil supplies with ample margin for flyback transients, and the integrated active clamp absorbs inductive kickback at turn-off, so no external freewheeling diode is required. Low input current draw allows direct connection to microcontroller outputs without buffer transistors. The dual-channel SO-8 package halves board area versus using two discrete protected switches, an advantage in dense relay-driver boards for industrial control panels.
Recomendado
Lamp and LED Driver (12V/24V)
The VNS1NV04D13TR can switch incandescent lamps, halogen bulbs, and high-current LED strings in automotive interior lighting, indicator lamps, and 24V industrial signaling applications. Each channel's 1.7A continuous rating covers typical 5W to 20W lamp loads at 12V, and the 40V clamp handles 24V truck and bus systems. The on-die thermal shutdown and current limit protect against the inrush current of cold incandescent filaments, which can exceed 10x steady-state current. The status pin indicates lamp-out or short-circuit conditions to the MCU, enabling built-in self-test and bulb-failure diagnostics required by modern automotive lighting standards.
Recomendado
Industrial PLC Discrete Output Module
Industrial 24V PLC output modules use the VNS1NV04D13TR's dual-channel SO-8 configuration to provide two protected outputs per IC, maximizing channel density on the module PCB. The 40V drain clamp handles the 24V supply plus inductive transient spikes from solenoids and contactors, while the 1.7A per-channel rating covers typical PLC output loads up to 40W. The integrated short-circuit and over-temperature protection meets IEC 61131-2 requirements for industrial digital outputs, and the status feedback pin simplifies per-channel fault reporting back to the module's microcontroller. The SO-8 footprint allows standard reflow soldering and automated optical inspection.
Recomendado
DC Motor Driver (Small Brushed)
The VNS1NV04D13TR can drive small brushed DC motors in 12V/24V applications such as HVAC damper actuators, valve actuators, and small pump motors. Each channel's 1.7A continuous rating covers fractional-horsepower motor loads, and the active clamp protects against the back-EMF generated when the motor is switched off or stalls. For unidirectional single-motor control, one channel drives the motor low-side while the other channel can remain unused or drive a brake/clutch. The thermal shutdown protects against stall conditions, an important feature for actuators that may jam during mechanical failure.
Recomendado
Battery-Powered Load Switch
In battery-powered systems such as e-bike controllers, portable industrial tools, and uninterruptible power supplies, the VNS1NV04D13TR serves as a protected load-disconnect switch between the battery and downstream circuitry. The 40V clamp rating covers multi-cell lithium battery packs (up to 10S), and the 1.7A continuous rating handles auxiliary loads such as lighting, fans, and control boards. The very low quiescent input current draw is critical for battery life, and the on-die protection ensures the load switch survives short-circuit events at the output connector without requiring external fuses or PTC devices.

Notas de diseño
Estimated: at 1.7A continuous per channel with RDS(on) of 250 mOhm, each channel dissipates approximately 0.72W; dual-channel continuous operation can reach 1.44W total. For the SO-8 package with theta_JA around 50 C/W on a standard 2-layer FR-4 PCB, junction temperature rises roughly 70C above ambient, which exceeds automotive-grade 150C limits at 85C ambient without copper area enhancement. ST recommends at least 100 mm^2 of 2-ounce copper pour per channel under the SOURCE pins, or forced air cooling, to keep Tj below 150C. In multi-channel boards, provide thermal relief between adjacent VNS1NV04D13TR devices to avoid thermal runaway.
Use a star-ground topology with separate power and signal grounds tied at a single point near the SOURCE pins. Route the high-current drain traces with minimum 35 um copper (1 oz) and at least 1.5 mm trace width per ampere. Place the input pull-down or pull-up resistors within 5 mm of the INPUT pins to prevent floating inputs during MCU reset. The STATUS pins can be tied together to a single MCU interrupt pin if both channels' fault status are monitored by the same controller; otherwise use separate GPIO inputs for per-channel diagnostics.
Do not connect the SOURCE pins to different ground potentials - both channels share a common internal reference and require a low-impedance common ground. Do not exceed 40V continuous drain-to-source voltage; the active clamp engages above this threshold and will dissipate avalanche energy as heat. Do not leave the INPUT pins floating; use a pull-down resistor to guarantee known OFF state during MCU boot or fault conditions. Finally, verify that the load's inrush current does not exceed the Ilim threshold for sustained periods, or the thermal shutdown will engage unexpectedly.
