STMicroelectronics VNV14N04

Overview

VNV14N04 from STMicroelectronics is a fully autoprotected monolithic Power MOSFET in the OMNIFET family, fabricated using VIPower M0 technology. It functions as a smart high-side switch with integrated linear current limiting (14 A), thermal shutdown (150 °C), 42 V overvoltage clamp, and diagnostic feedback via the input pin. Designed for DC–50 kHz switching in industrial motor control, solenoid drivers, and lighting ballasts.

For engineers reviewing the VNV14N04 datasheet, VNV14N04 pinout, VNV14N04 application, or VNV14N04 equivalent, key selection criteria include its 0.07 Ω R_DS(on) at 10 V_IN, fault-sink capability (50 mA), direct gate access for analog driving, and PowerSO-10 package thermal resistance (2.5 °C/W junction-to-case).

Technical Context

The VNV14N04 integrates a power MOSFET stage with on-chip protection logic that operates independently of input voltage - enabling robust operation under short-circuit or overtemperature conditions. Its linear current limiter activates at 14 A (typ.) and holds drain current constant regardless of V_IN, while the internal clamp limits V_DS to 42 V during inductive flyback.

Fault detection is implemented by disconnecting the input from the gate and sinking current to ground (100 Ω equivalent) when T_j ≥ 150 °C or I_D exceeds limit. The device supports TTL-level input drive and provides ESD immunity (2000 V HBM), with diagnostic feedback directly observable at the input pin without external circuitry.

FAQ

What is the maximum continuous drain current for VNV14N04 under typical PCB layout conditions?

The VNV14N04 is rated for 14 A continuous drain current when mounted on a 4-layer PCB with 200 mm² copper pour under the PowerSO-10 tab and case temperature maintained at ≤ 25 °C. At higher case temperatures, current must be derated per the datasheet's Figure 3 - e.g., 10 A at T_c = 70 °C - due to thermal limits and internal current limiting behavior.

Can VNV14N04 be used in linear (analog) mode, and what design considerations apply?

Yes - the VNV14N04 supports analog driving via direct gate access at the INPUT pin, enabling linear regulation. Key considerations include strict thermal management (power dissipation = I_D × V_DS), avoidance of prolonged operation in the linear region to prevent thermal shutdown, and use of external gate resistor to control dV/dt and ensure stability during transitions.

How does the diagnostic feedback signal behave during an overtemperature fault?

During overtemperature fault (T_j ≥ 150 °C), the internal protection circuit disconnects the INPUT pin from the gate and connects it to ground through a ~100 Ω internal resistor. This pulls the input pin voltage to near 0 V while sinking ~50 mA - a clear, measurable condition detectable by any microcontroller GPIO configured as input with pull-up.

Is VNV14N04 pin-compatible with VNB14N04 or VNK14N04FM?

No - although functionally identical and sharing the same electrical specs, VNV14N04 uses the PowerSO-10 package (10-pin), while VNB14N04 is in D2PAK and VNK14N04FM is in SOT-82-FM. Mechanical pinouts differ significantly; PCB layout and thermal pad design are not interchangeable between these variants.
