Product details

Overview

VNS3NV04TR-E from STMicroelectronics is a fully autoprotected VIPower™ M0-3 monolithic high-side power switch IC in SO-8 package, designed as a robust replacement for standard Power MOSFETs in DC–50 kHz switching applications. It features integrated linear current limitation (3.5 A typ), thermal shutdown (170 °C typical trip), 40 V drain-source clamp, 120 mΩ R_DS(on) at 5 V input, and diagnostic feedback via the input pin. It is used in industrial motor control, solenoid drivers, and automotive body electronics where fault resilience is critical.

For engineers reviewing the VNS3NV04TR-E datasheet, VNS3NV04TR-E pinout, VNS3NV04TR-E application, or VNS3NV04TR-E equivalent, this page delivers verified technical context, real-world protection behavior, SO-8 pin-level design meaning, and validated alternatives for high-side load switching with built-in diagnostics and ruggedness against overcurrent, overtemperature, and inductive transients.

Technical Context

The device operates as a high-side switch with direct gate access for analog driving, drawing only 100 µA supply current from the input pin during normal operation. Its internal linear current limiter activates at 3.5 A (typ) and holds ID constant regardless of input voltage, forcing operation in the linear region under overload - requiring careful thermal management.

Protection is hardware-based and autonomous: overvoltage clamp triggers at 40 V (min), thermal shutdown occurs between 150–200 °C (typ 170 °C), and fault indication is delivered via sink current (10–20 mA) on the input pin when junction temperature exceeds T_jsh. No external components are required to enable these protections.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	120 mΩ max at V_IN = 5 V, I_D = 1.5 A, T_j = 25 °C - enables low conduction loss in high-side loads up to ~3.5 A continuous.
I_lim	3.5 A typ at V_IN = 5 V, V_DS = 13 V - provides repeatable current limiting independent of input drive level.
V_CLAMP	40 V min at I_D = 1.5 A - clamps inductive kickback to protect downstream circuitry without external TVS.
T_jsh	150–200 °C range (typ 170 °C) - shuts down power stage before silicon damage; auto-restarts after ~15 °C cooldown.
I_gf	10–20 mA fault sink current on input pin - signals overtemperature event to controller without added sensors or logic.
IISS	100–150 µA supply current from input pin - allows direct TTL/CMOS drive with minimal loading on control logic.
E_AS	100 mJ single-pulse avalanche energy - sustains unclamped inductive switching stress (e.g., relay/solenoid turn-off) without failure.

Pinout & Package

SO-8 package (body size 4.9 × 6.0 mm, 1.27 mm pitch); thermally enhanced layout with DRAIN pins (1, 4, 5, 8) tied to exposed pad for improved heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1, 4, 5, 8	DRAIN	Power output node; internally connected to MOSFET drain; must be routed to high-current load path and thermally coupled to PCB copper.
2	INPUT	Logic-level gate control input; supplies internal bias (100 µA) and sinks fault current (10–20 mA) during thermal shutdown.
3, 6, 7	SOURCE	Power return / ground reference; tied to internal MOSFET source and substrate; connects to system GND plane for stability and EMI control.

Key Features

Feature	Design Value
Linear current limitation	Maintains precise 3.5 A (typ) output current under overload - eliminates need for external current-sense amplifier and comparator loop.
Integrated overvoltage clamp	40 V clamp threshold protects against inductive flyback without external snubber or TVS diode - reduces BOM count and board area.
Thermal shutdown with auto-restart	Shuts off at ~170 °C junction temp and resumes operation after ~15 °C hysteresis - enables self-recovering behavior in intermittent overload conditions.
Diagnostic feedback via INPUT pin	10–20 mA sink current during fault indicates overtemperature event directly to MCU GPIO - no extra signal line or ADC channel required.
Direct analog gate drive capability	Allows linear regulation (e.g., PWM dimming, soft-start) by varying input voltage - supports analog control without digital interface overhead.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side protected switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Integrated H-bridge driver with current regulation; requires external sense resistor; no integrated clamp or thermal shutdown.	Designed for bidirectional DC motor control, not single high-side switching.	Select only if bidirectional motion and microstepping are required; lacks VNS3NV04TR-E's autonomous protection and simplicity for unidirectional loads.
TPS27081A	Lower R_DS(on) (60 mΩ), but no current limiting or overvoltage clamp; only thermal shutdown and fault flag (open-drain).	Targeted at USB power delivery and e-fuse applications; lacks ruggedness for inductive loads.	Choose when ultra-low on-resistance and fast response (<1 µs) are critical, and external protection (TVS, current sense) is acceptable.

Compared with STSPIN250 and TPS27081A, the VNS3NV04TR-E uniquely combines linear current limiting, integrated 40 V clamp, and diagnostic sink current in a single SO-8 package - making it optimal for cost-sensitive, space-constrained high-side switching where inductive stress and thermal transients are routine.

FAQ

What is the maximum continuous drain current for VNS3NV04TR-E?

The device features a linear current limiter set to 3.5 A (typical) at V_IN = 5 V and V_DS = 13 V. This is not a safe continuous rating - sustained current limiting causes self-heating. Continuous DC current depends on PCB thermal design; with 50 mm² copper on FR4, derated to ~1.5 A at 25 °C ambient per Figure 11.

Can VNS3NV04TR-E drive inductive loads without external protection?

Yes - its integrated 40 V overvoltage clamp and 100 mJ single-pulse avalanche energy rating allow direct connection to solenoids, relays, and small DC motors without external TVS diodes or snubbers. However, for repetitive inductive switching, thermal management remains critical due to linear-mode power dissipation during current limiting.

How does the diagnostic feedback on the INPUT pin work?

During thermal shutdown, the device sinks 10–20 mA through the INPUT pin. If driven by a low-impedance source (e.g., MCU GPIO with pull-up), this pulls the pin voltage low - detectable as a logic-low fault signal. With high-impedance drive, the pin collapses to 0 V, still indicating fault without affecting switch operation.

Is VNS3NV04TR-E compatible with 3.3 V logic controllers?

Yes - its input threshold voltage is specified from 0.5 V (min) to 2.5 V (max) at I_D = 1 mA, and it draws only 100–150 µA from the input pin. A 3.3 V CMOS output can reliably drive it, though full R_DS(on) performance (120 mΩ) requires ≥5 V input per datasheet test conditions.
