Product details

Overview

VNQ5E250AJ-E from STMicroelectronics is a quad-channel automotive high-side driver in PowerSSO-16 package, designed to switch 12 V grounded resistive/inductive/capacitive loads with integrated analog current sensing per channel. It features 250 mΩ typical on-resistance, 5 A current limitation, ±9% current sense ratio drift over temperature, and 2 µA standby supply current. Used for LED and relay driving in body control modules.

For engineers reviewing the VNQ5E250AJ-E datasheet, VNQ5E250AJ-E pinout, VNQ5E250AJ-E application, or VNQ5E250AJ-E equivalent, this page delivers verified electrical specs, diagnostic behavior, thermal performance, protection thresholds, and real-world automotive load interface requirements - all confirmed from ST's official datasheet (Doc ID 17360 Rev 3).

Technical Context

The device implements four independent VIPower™ M0-5 high-side switches with active power limitation for inrush and overload management, plus dedicated analog current sense outputs (CS1–CS4) delivering proportional I_OUT/I_SENSE ratios from 295 to 705 across load and temperature. Each channel supports CMOS-compatible 3 V/5 V inputs with 0.25 V hysteresis and integrates off-state open-load detection, short-to-V_CC diagnosis, and thermal shutdown with auto-restart.

Protections include undervoltage shutdown at 4 V (0.5 V hysteresis), overvoltage clamp up to 52 V, reverse battery tolerance via external GND network, and self-limiting fast thermal transients. The CS_DIS pin enables global current sense disable to share external sense resistors across multiple devices.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands automotive load dump transients without external clamping
Operating voltage range	4–28 V - supports cold-crank (4 V) to boosted systems (28 V) in 12 V architectures
On-state resistance (typ)	250 mΩ - limits conduction loss to ≤125 mW at 0.5 A, enabling compact thermal design
Current limitation (typ)	5 A - actively limits fault current during short-to-ground, preventing wire harness damage
Standby supply current	2 µA - enables always-on functionality in low-power body electronics without battery drain
Current sense accuracy	±9% ratio drift over -40°C to +150°C - enables reliable fault classification across full automotive temperature range
Thermal shutdown threshold	150–200°C - protects die during sustained overload; auto-restart occurs after junction cools to ~135°C

Pinout & Package

Package: PowerSSO-16 (exposed thermal pad connected to V_CC), surface-mount, RoHS-compliant, ECOPACK® certified.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary 12 V rail connection; powers internal circuitry and supplies exposed thermal pad
GND	Ground reference	Must be reverse-battery protected externally (diode/resistor network) per ST application guidance
INPUT1–INPUT4	CMOS-compatible control inputs	3.0 V/5.0 V logic compatible with MCU GPIO; 0.25 V hysteresis prevents noise-induced switching
OUTPUT1–OUTPUT4	High-side switched outputs	Drive grounded loads directly; each includes integrated reverse-battery diode (V_F = 0.7 V @ 0.5 A)
CURRENT SENSE1–CURRENT SENSE4	Analog current feedback outputs	Deliver I_SENSE = I_OUT/K (K = 295–705); enable real-time load monitoring and fault discrimination
CS_DIS	Global current sense disable	Active-high signal; disables all four CS outputs to share single external sense resistor across multiple drivers

Key Features

Feature	Design Value
Inrush current active management	Power limitation architecture dynamically caps dI/dt during cold-crank startup, preventing fuse blow and EMI spikes
Proportional analog current sense	Four independent CS pins with <100 µs response time enable precise load classification (e.g., distinguish LED vs solenoid vs motor)
Off-state open-load detection	Validates load continuity before activation using internal bias current; detects broken wires or disconnected bulbs
Short-to-V_CC diagnosis	Detects output shorted to battery rail via differential voltage monitoring - critical for safety-critical lighting circuits
Reverse battery protection support	Integrated GND path design allows external diode/resistor network to block -14 V reverse polarity without external MOSFET

Applications

Use Scenario: Driving high-brightness LED arrays in adaptive front-lighting systems (AFS) requiring PWM dimming and fault logging.

IC Role / Device Role / Timing Role: High-side switch with fast turn-on/turn-off (<10 µs delay) and accurate current mirroring for closed-loop LED current regulation.

Use Value: Enables real-time LED current monitoring without shunt resistor, preserving efficiency and PCB space while supporting ASIL-B functional safety diagnostics.

Engine Bay Relay Interface

Industrial Solenoid Control

Use Scenario: Replacing electromechanical relays for fuel pump, radiator fan, and horn control in harsh under-hood environments.

IC Role / Device Role / Timing Role: Robust high-side driver with 41 V clamp and thermal auto-restart, handling inductive kickback and ambient temperatures up to 150°C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad-channel high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (350 mΩ typ), no per-channel analog current sense - uses digital SPI diagnostics only	Lacks analog I_SENSE for continuous current monitoring; requires external ADC or microcontroller with high-resolution analog input	Select when SPI-based diagnostics and lower BOM count outweigh need for analog current feedback
BD82001FV-M	Single-channel only; 120 mΩ R_ON; no thermal auto-restart - latches off after overtemperature	Requires four separate ICs for quad functionality; no built-in open-load or short-to-V_CC detection	Select for ultra-low R_ON in space-constrained single-load designs where discrete diagnostics are acceptable

Compared with TPS4H160-Q1 and BD82001FV-M, the VNQ5E250AJ-E uniquely combines per-channel analog current sense, thermal auto-restart, and comprehensive fault diagnostics in a single quad-channel package - reducing system component count and enabling predictive maintenance in automotive body electronics.

FAQ

What is the maximum continuous output current per channel?

The VNQ5E250AJ-E provides 5 A typical current limitation (I_LIMH) per channel under DC short-circuit conditions at V_CC = 13 V. Continuous safe operating current depends on PCB copper area and ambient temperature; with 200 cm² double-sided copper, it supports ≥2.5 A per channel at 85°C ambient. Thermal derating curves are provided in Figure 36 of the datasheet.

How does the current sense function work, and what external components are required?

Each CURRENT SENSE pin delivers an analog current I_SENSE = I_OUT/K, where K ranges from 295 to 705 depending on load and temperature. An external sense resistor (e.g., 3.9 kΩ or 10 kΩ) converts I_SENSE to a measurable voltage. No op-amp or ADC is required for basic fault detection, though precision measurement benefits from a 12-bit+ ADC due to ±9% ratio drift.

Can VNQ5E250AJ-E drive inductive loads like fuel pumps or fans?

Yes - it is qualified for inductive loads with demagnetization energy up to 39 mJ (L = 36 mH, V_BAT = 13.5 V). The integrated overvoltage clamp (41–52 V) absorbs flyback energy, and the "V_ON output voltage drop limitation" feature ensures controlled turn-off. External freewheeling diodes are not required, but layout must minimize parasitic inductance in the output loop.

Is reverse battery protection built-in, or does it require external components?

Reverse battery protection is not fully integrated - the GND pin must be protected externally using either a series resistor (R_GND) or Schottky diode (D_GND) as specified in Section 3.1 of the datasheet. This external network blocks -14 V reverse polarity while maintaining low forward voltage drop and avoiding thermal runaway during normal operation.
