STMicroelectronics VNP14NV04-E

Overview

VNP14NV04-E from STMicroelectronics is a monolithic VIPower™ M0-based protected Power MOSFET designed for DC–50 kHz switching in automotive and industrial load control. It delivers 35 mΩ R_DS(on) at V_IN = 5 V, 12 A current limiting, 40 V integrated overvoltage clamp, and diagnostic feedback via the input pin-enabling robust replacement of standard MOSFETs in solenoid, relay, and LED driver circuits.

For engineers reviewing the VNP14NV04-E datasheet, VNP14NV04-E pinout, VNP14NV04-E application, or VNP14NV04-E equivalent, this page provides verified technical context, protection behavior under fault conditions, thermal derating curves, and real-world design implications for inductive load switching and fault diagnostics.

Technical Context

The VNP14NV04-E integrates linear current limiting, thermal shutdown (T_jsh = 150–200 °C), and an internal 40 V drain-source clamp to protect against inductive kickback. Its input pin directly drives the gate with only 100–150 µA supply current, enabling TTL-compatible control without external level-shifting.

Fault detection occurs via sink current (I_gf = 10–20 mA) on the input pin during overtemperature events, while ESD protection meets 4 kV HBM and 16.5 kV output-pin-specific standards. The device operates up to 50 kHz with 80–250 ns turn-on delay and 350–1000 ns rise time under 10 Ω gate drive.

FAQ

What is the maximum continuous drain current for VNP14NV04-E at 25 °C ambient?

The device does not specify a fixed continuous I_D rating due to its thermal shutdown architecture. At T_c = 25 °C, P_tot = 74 W (DPAK package) implies ~27 A theoretical limit, but the 12 A current limiter activates first under sustained load. Real-world continuous current depends on PCB copper area, airflow, and thermal interface-typically 4–8 A with 2 cm² copper pour and no forced cooling.

Can VNP14NV04-E be used as a low-side switch?

No-it is configured exclusively as a high-side switch with source tied to ground and drain connected to the load. The internal protection circuitry, current sensing, and diagnostic feedback are referenced to the source terminal, making low-side operation electrically incompatible and unsafe.

How does the input pin provide fault feedback during thermal shutdown?

When junction temperature exceeds T_jsh, the device sinks 10–20 mA through the input pin. If driven by a high-impedance source (e.g., open-drain GPIO), the pin voltage collapses to near 0 V, signaling fault. With low-impedance drive, the current flows into the controller, which can monitor voltage drop across a series resistor to detect the event.

Is external clamping required when switching inductive loads?

No-VNP14NV04-E includes an internal 40 V drain-source clamp that activates during inductive flyback. This eliminates the need for external freewheeling diodes or TVS devices in 12 V systems. For 24 V systems with higher energy storage, verify E_AS margin using the 400 mJ single-pulse rating and load inductance per Figure 29.
