STMicroelectronics VNS7NV04PTR-E

Overview

VNS7NV04PTR-E from STMicroelectronics is a monolithic OMNIFET II fully autoprotected N-channel Power MOSFET in SO-8 package, designed for DC–50 kHz switching in automotive and industrial load control. It features 60 mΩ R_DS(on) at 5 V gate drive, 6 A linear current limit, 40 V integrated overvoltage clamp, thermal shutdown at 150–200 °C, and diagnostic feedback via input pin-used in motor driver outputs, solenoid drivers, and lighting control modules.

For engineers reviewing the VNS7NV04PTR-E datasheet, VNS7NV04PTR-E pinout, VNS7NV04PTR-E application, or VNS7NV04PTR-E equivalent, key selection criteria include its integrated linear current limiter (6–12 A), fault-sink diagnostic capability (15 mA), low 100–150 µA input supply current, and rugged unclamped inductive switching performance up to 37–40 mJ.

Technical Context

This device integrates gate driver, protection logic, and power stage in VIPower™ M0-3 technology. Its linear current limiter operates independently of input voltage, maintaining constant I_lim across -40 °C to 150 °C junction temperature, while overtemperature shutdown triggers at 150–200 °C with automatic restart after ~15 °C hysteresis.

The internal overvoltage clamp activates at 36 V threshold and clamps to 40–55 V during inductive turn-off, enabling robust energy handling without external snubbers. Diagnostic feedback uses the same input pin for both control and fault signaling-sinking 15 mA when thermal shutdown occurs, compatible with TTL-level drive sources.

FAQ

What is the maximum continuous drain current for VNS7NV04PTR-E?

The device delivers 6 A continuous drain current under linear current limiting conditions at 25 °C ambient with adequate PCB copper area. Derating applies above 25 °C per Figure 9 in ST Doc ID 15632 Rev 4-e.g., ~4.5 A at 85 °C case temperature with standard FR4 layout.

Can VNS7NV04PTR-E be driven directly from a microcontroller GPIO?

Yes-it draws only 100–150 µA from the input pin during normal operation and accepts TTL-compatible 0.5–6.8 V logic levels. No external level shifter or buffer is needed, though series resistance ≥150 Ω is recommended for EMI suppression and gate charge control.

How does the diagnostic feedback function during thermal shutdown?

When junction temperature exceeds 150–200 °C, the device actively sinks 15 mA through the INPUT pin. If driven by a low-impedance source, this pulls the input voltage low; if driven by high impedance, the pin falls to 0 V-both states indicate fault without interrupting operation.

Is an external flyback diode required when switching inductive loads?

No-its integrated 40–55 V overvoltage clamp and 40 mJ unclamped inductive energy rating eliminate the need for external flyback diodes in typical 12–24 V automotive and industrial applications, as verified in Figures 30–33 of the datasheet.
