STMicroelectronics VNS7NV04-E

Overview

VNS7NV04-E from STMicroelectronics is a monolithic OMNIFET II fully autoprotected Power MOSFET in SO-8 package, designed as a robust replacement for standard Power MOSFETs in DC–50 kHz switching applications. It features 60 mΩ R_DS(on) at V_IN = 5 V and I_D = 3.5 A, 6 A linear current limit, integrated overvoltage clamp (40–55 V), thermal shutdown (150–200 °C), and diagnostic feedback via the input pin. It is used in automotive body control modules for driving resistive and inductive loads such as lamps and solenoids.

For engineers reviewing the VNS7NV04-E datasheet, VNS7NV04-E pinout, VNS7NV04-E application, or VNS7NV04-E equivalent, key selection criteria include its linear current limiting behavior, fault-sink diagnostic capability (15 mA Igf), SO-8 thermal resistance (R_thj-case = 2.1 °C/W), unclamped inductive energy handling (40 mJ), and compatibility with TTL-level logic drive.

Technical Context

This device integrates a VIPower M0-3 process Power MOSFET with on-chip protection circuitry including a voltage-controlled linear current limiter, thermal sensing with hysteresis (T_jsh = 150–200 °C, T_jrs = 135 °C), and an overvoltage clamp active at ~45 V. Its gate is directly accessible for analog driving, enabling precise control of conduction slope and power dissipation during fault conditions.

The input pin serves dual roles: it drives the internal gate (with IISS ≤ 150 µA) and provides fault status feedback by sinking up to 15 mA (Igf) when thermal shutdown occurs. Protection activation is independent of input voltage - current limiting and thermal shutdown respond solely to internal chip conditions, ensuring reliable operation under load faults or ambient temperature extremes.

FAQ

What is the maximum continuous drain current for VNS7NV04-E at 85 °C case temperature?

At T_c = 85 °C, derating per Figure 9 limits continuous I_D to approximately 3.2 A due to thermal constraints - calculated using R_thj-case = 2.1 °C/W and T_jmax = 150 °C. This assumes adequate PCB copper area (≥100 mm²) and still-air conditions. For higher currents, forced airflow or larger copper pours are required.

Can VNS7NV04-E be used in parallel configurations?

No - VNS7NV04-E is not characterized or recommended for paralleling. Its linear current limiter and thermal shutdown thresholds vary across units, leading to uneven current sharing and potential thermal runaway. STMicroelectronics specifies single-device operation only; use higher-current alternatives like VND7NV04-E for >6 A loads.

Does the input pin require a pull-up resistor for proper logic-level operation?

No pull-up is required. The input pin draws only 100–150 µA during normal operation and is compatible with TTL and CMOS logic outputs. However, a series resistor ≥150 Ω must be used to limit input current during fault conditions when Igf (15 mA) is sunk - this prevents excessive voltage drop and ensures reliable fault signaling.

How does the diagnostic feedback behave when driven by a high-impedance microcontroller GPIO?

When the input pin driver cannot supply Igf (15 mA), the INPUT pin voltage collapses to near 0 V during thermal fault - providing a clear logic-low signal detectable by any GPIO. No external pull-down is needed, and the device continues normal operation after fault clearance; the MCU can monitor this level change to trigger alerts or log events.
