STMicroelectronics VNP14NV04

Overview

VNP14NV04 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 7 A, 12 A linear current limit, 40 V integrated overvoltage clamp, thermal shutdown at 150–200 °C, and diagnostic feedback via input pin voltage drop.

For engineers reviewing the VNP14NV04 datasheet, VNP14NV04 pinout, VNP14NV04 application, or VNP14NV04 equivalent, this device serves as a robust, self-protected high-side switch replacement for standard MOSFETs in harsh environments-especially where inductive load management, fault detection, and board-level reliability are critical.

Technical Context

The VNP14NV04 integrates a power MOSFET with analog gate drive capability, enabling direct TTL-compatible control without external level-shifting. Its linear current limiter activates independently of input voltage, maintaining constant I_lim across temperature and supply variations.

Protection logic combines junction temperature sensing (for 150–200 °C thermal shutdown), avalanche-rated drain-source clamping (40–55 V), and input-pin-based fault signaling (I_gf = 10–20 mA sink during overtemperature). All protections operate autonomously without external circuitry.

FAQ

What is the maximum continuous drain current for VNP14NV04?

The device features a linear current limiter set to 12 A minimum under typical conditions (V_IN = 5 V, V_DS = 13 V). Continuous operation above this limit is not permitted - the device enters linear regulation to hold current constant, increasing power dissipation until thermal shutdown activates at 150–200 °C.

Can VNP14NV04 be driven directly from a microcontroller GPIO?

Yes. The input pin draws only 100–150 µA during normal operation and accepts 0–5 V logic levels, making it compatible with standard MCU GPIOs without buffering. During fault, it sinks 10–20 mA - ensure the GPIO can tolerate brief 0 V pull-down or add a weak pull-up resistor for clean fault detection.

Does VNP14NV04 require an external freewheeling diode?

No. The integrated 40–55 V overvoltage clamp and 400 mJ avalanche energy rating allow safe operation with inductive loads without an external flyback diode. This is validated for unclamped inductive switching up to 24 mH at 13.5 V, per ST's test conditions in Figure 5.

How is thermal shutdown reset after activation?

Thermal shutdown resets automatically when junction temperature falls approximately 15 °C below the trip point (e.g., from 170 °C to ~155 °C). No external reset signal is needed - the device resumes normal switching once thermally recovered, provided input voltage remains applied and fault condition is removed.
