Product details

Overview

VNP49N04FI-E from STMicroelectronics is a fully autoprotected monolithic VIPower M0 high-side power switch MOSFET with integrated linear current limiting (49 A), overvoltage clamp (42 V), thermal shutdown (150 °C), and diagnostic feedback via input pin. It replaces standard N-channel MOSFETs in DC–50 kHz industrial motor control, solenoid drivers, and automotive body electronics.

For engineers reviewing the VNP49N04FI-E datasheet, VNP49N04FI-E pinout, VNP49N04FI-E application, or VNP49N04FI-E equivalent, this device's real-time fault reporting, analog gate access for linear operation, and rugged 4 J single-pulse avalanche energy are critical for safety-critical load switching designs requiring self-protection without external sensing circuitry.

Technical Context

The VNP49N04FI-E integrates a power MOSFET stage with on-chip protection logic including voltage-clamp-triggered avalanche energy handling, temperature-sensed thermal shutdown independent of input voltage, and linear current limiting active across VIN = 5–10 V. Its status feedback mechanism pulls the INPUT pin to ground through 100 Ω during overtemperature fault, enabling simple microcontroller-level detection.

It operates as a high-side switch with direct gate access for analog driving, supports TTL-compatible input logic, and features built-in ESD protection (2000 V HBM). The device's R_DS(on) remains stable at 20 mΩ (typ.) at T_c = 25°C with VIN = 10 V and ID = 25 A, and its transconductance (g_fs) is 25–30 S under same conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CLAMP	42 V - Internally clamped drain-source voltage protects against inductive kickback up to 42 V without external TVS.
R_DS(on)	20 mΩ - Low conduction loss enables 49 A continuous current with <1 W dissipation at 25 A (T_c = 25°C).
I_LIM	49 A - Linear current limit activates regardless of input voltage, ensuring predictable overload behavior in motor/solenoid loads.
T_jsh / T_jrs	150 °C / 135 °C - Thermal shutdown and auto-restart hysteresis prevents latch-up and enables self-recovery after transient overloads.
Q_i	100 nC - Total input charge determines gate drive energy requirement; compatible with standard 10 Ω gate drivers for <1 µs turn-on delay.
E_as	4 J - Single-pulse avalanche energy rating ensures survivability during unclamped inductive switching events.
V_IN(th)	0.8–3 V - Input threshold voltage allows direct TTL/CMOS logic interface without level-shifting.

Pinout & Package

Package: PowerSO-10™ (10-pin surface-mount, thermally enhanced SOIC variant with exposed drain pad).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8, 9	Source	Internally paralleled source terminals - low-inductance return path; must be connected to PCB ground plane for thermal and electrical performance.
10	Drain	Main power output terminal - electrically tied to exposed metal pad; requires large copper pour for heat dissipation and current handling.
Input (Pin 10 not used for input; INPUT is Pin 1–3 per top-view diagram)	Input/Gate Control	Pin 1 (INPUT) connects directly to internal gate; supplies bias current (250–550 µA) and provides fault feedback by sinking to ground during thermal fault.

Key Features

Feature	Design Value
Integrated Overvoltage Clamp	42 V clamping with rugged avalanche capability eliminates need for external TVS in 24 V automotive and industrial systems.
Linear Current Limiting	49 A limit maintained across input voltages (5–10 V), enabling predictable short-circuit response without current-sense resistors.
Diagnostic Feedback via INPUT Pin	Internal 100 Ω pull-down activated during thermal fault - detectable with single resistor and MCU ADC or GPIO.
Direct Gate Access	Analog driving capability allows linear-mode operation for precision current regulation or soft-start control.
ESD Protection	2000 V HBM rating ensures robustness during board assembly and field handling without additional protection circuitry.

Applications

IC Role / Device Role / Timing Role: High-side protected switch replacing mechanical relay or discrete MOSFET + protection IC stack.

Use Value: Eliminates external current sense, thermal sensor, and clamp diode - reduces BOM count by ≥4 components while improving reliability.

Use Scenario: Controlling 24 V DC solenoids in packaging machinery, valve actuation, and pneumatic systems where short-circuit and overtemperature events are common.

IC Role / Device Role / Timing Role: Self-protected high-current switch with fast (<1 µs) fault reporting to PLC I/O module.

Use Value: Enables predictive maintenance via real-time current limit monitoring and automatic recovery after thermal overload.

DC Motor Starter Circuit

Smart Power Distribution Unit

Use Scenario: Starting brushed DC motors in power tools or automotive auxiliary pumps where inrush current exceeds steady-state rating.

IC Role / Device Role / Timing Role: High-side switch with linear current limiting and 4 J avalanche energy absorption during stall conditions.

Use Value: Prevents MOSFET destruction during locked-rotor events without sacrificing startup torque or requiring complex current-loop control.

Use Scenario: Distributed power rail switching in industrial control cabinets with remote fault reporting and hot-swap capability.

IC Role / Device Role / Timing Role: Intelligent power switch with status feedback to central controller via shared input line.

Use Value: Reduces wiring complexity by multiplexing fault signaling onto control line - no dedicated fault bus required.

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
STSPIN32F0B	Integrated 3-phase BLDC driver with embedded MCU and current sensing; lacks discrete high-current linear limiting and 42 V clamp.	Targeted at closed-loop motor control, not simple on/off load switching.	Select when vector control or commutation timing is required; not drop-in for relay replacement.
IPS1021H	Lower current rating (12 A), higher R_DS(on) (100 mΩ), identical protection architecture and 42 V clamp.	Better suited for low-power auxiliary loads (e.g., LED drivers, small fans) where thermal footprint is constrained.	Select for space-constrained designs needing same protection features at reduced current capacity.

Compared with STSPIN32F0B and IPS1021H, the VNP49N04FI-E uniquely delivers 49 A linear current limiting with 20 mΩ R_DS(on) and 4 J avalanche energy in a single PowerSO-10 package - making it optimal for high-power, high-ruggedness open-loop switching where simplicity and fault resilience outweigh programmability needs.

FAQ

What is the maximum continuous drain current for VNP49N04FI-E at T_c = 100°C?

At case temperature T_c = 100°C, the maximum continuous drain current is derated to approximately 35 A, based on the R_thj-case = 1 °C/W and T_jsh = 150 °C limit. This assumes adequate heatsinking and ambient airflow; actual value depends on PCB copper area and thermal interface quality.

Can VNP49N04FI-E be used in parallel configurations for higher current?

No - VNP49N04FI-E is not characterized or recommended for paralleling due to mismatch in R_DS(on) (±25%) and thermal coupling effects. Its integrated current limiting is per-device only; paralleling risks uneven current sharing and premature thermal shutdown of one unit.

How does the diagnostic feedback signal behave during overtemperature fault?

During overtemperature fault, the internal protection circuit disconnects the INPUT pin from the gate and connects it to ground via a 100 Ω resistor. Measured at the INPUT pin, voltage drops to ≤0.5 V (with typical 10 kΩ pull-up), providing unambiguous digital fault indication without additional components.

Is the VNP49N04FI-E compliant with AEC-Q100 for automotive use?

No - VNP49N04FI-E is not AEC-Q100 qualified. It is rated for industrial temperature range (−40°C to 125°C) and intended for non-safety-critical automotive body applications. For AEC-Q100-compliant alternatives, consider ST's VIPower M0-7 family (e.g., VNQ7E050AK).
