Product details

Overview

VN5E050AJTR-E from STMicroelectronics is a single-channel automotive high-side driver in PowerSSO-12 package, featuring analog current sense, 50 mΩ R_ON, 27 A typical current limit, and CMOS-compatible 3.0 V input logic. It drives 12 V grounded resistive/inductive/capacitive loads-such as headlights, solenoids, and LED arrays-with integrated diagnostics including open-load detection, short-to-VCC sensing, and thermal shutdown with autorestart.

For engineers reviewing the VN5E050AJTR-E datasheet, VN5E050AJTR-E pinout, VN5E050AJTR-E application, or VN5E050AJTR-E equivalent, this page delivers verified technical context, validated pin functions, real-world automotive use cases, and confirmed alternative parts with documented functional differences for robust system design and BOM optimization.

Technical Context

The device implements active power limitation to manage inrush and overload currents while maintaining stable output voltage via internal clamp circuitry (41–52 V). Its VIPower M0-5 process enables precise analog current sensing (K₀ = 1170–3090) across -40°C to 150°C, with dedicated CS_DIS pin enabling shared external sense resistor usage.

Diagnostic architecture supports simultaneous fault reporting: OFF-state open-load detection (V_OL = 2–4 V), short-to-VCC identification (t_DSTKON = 180–1200 µs), and thermal shutdown indication (T_TSD = 150–200°C) with 7°C hysteresis and autorestart behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands automotive load-dump transients without external clamping
Operating voltage range	4.5 V to 28 V - supports cold-crank (4.5 V) and boosted battery (28 V) conditions
On-state resistance	50 mΩ (typ, 25°C) - limits conduction loss to ≤200 mW at 2 A, enabling compact thermal design
Current limit (typ)	27 A - sustains short-circuit events while limiting junction temperature rise
Off-state supply current	2 µA - ensures negligible battery drain during vehicle sleep mode
Current sense ratio	1170–3090 (K₀) - provides scalable analog feedback for MCU-based current monitoring across full operating range
Thermal shutdown threshold	150°C - triggers protection before silicon degradation, with 7°C hysteresis for stable recovery

Pinout & Package

Package: PowerSSO-12 - thermally enhanced surface-mount package with exposed die pad tied to VCC, optimized for automotive PCB layouts requiring low R_thj-amb (2.7 °C/W junction-to-case).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail connection; also ties to exposed thermal pad for heat dissipation
OUTPUT	High-side power output	Drives grounded loads; features active overvoltage clamp and demagnetization energy handling
GND	Ground reference	Must be reverse-battery protected externally; serves as return path for sense and logic circuits
INPUT	CMOS-compatible control input	3.0 V logic compatible with microcontrollers; includes 0.25 V hysteresis for noise immunity
CURRENT SENSE	Analog current feedback output	Delivers proportional current (I_SENSE) for real-time load monitoring and fault classification
CS_DIS	Current sense disable control	Active-high signal disabling analog sense output, enabling shared external sense resistor topology

Key Features

Feature	Design Value
Inrush current management	Power limitation prevents voltage sag during cold-crank startup of high-capacitance loads (e.g., LED modules)
Proportional analog current sense	±10% K-ratio drift over -40°C to 150°C enables accurate MCU-based current reconstruction without calibration
Off-state open-load detection	Validates load integrity during key-off state using V_OL threshold (2–4 V), critical for safety-critical lighting systems
Short-to-VCC detection	Identifies wiring faults within 1.2 ms after turn-off, preventing false ON-state assertions in harness diagnostics
Reverse battery protection support	Integrated ESD and clamp structures allow external GND-line diode/resistor network per Figure 32 for ISO 16750-2 compliance

Applications

Automotive Headlight Control

Engine Solenoid Actuation

Use Scenario: Driving 12 V halogen or LED headlamps with PWM dimming and fault logging.

IC Role / Device Role / Timing Role: High-side switch providing load isolation, current-sense feedback for brightness regulation, and open-load detection for bulb-out alerts.

Use Value: Enables ASAM-compliant diagnostic trouble code (DTC) generation for lamp failure without additional sensors or MCU ADC overhead.

Use Scenario: Controlling fuel injector or turbocharger wastegate solenoids in engine management units.

IC Role / Device Role / Timing Role: Robust power switch delivering fast turn-on/off (20/40 µs delays) and demagnetization energy handling up to 104 mJ.

Use Value: Eliminates need for external flyback diodes and reduces PCB area by integrating clamp and current-limiting functions.

Body Control Module (BCM) Outputs

Commercial Vehicle Lighting

Use Scenario: Managing door locks, window motors, and interior lighting in centralized BCMs.

IC Role / Device Role / Timing Role: Fault-tolerant high-side driver with thermal shutdown autorestart and undervoltage lockout (4.5 V).

Use Value: Ensures fail-safe operation during battery voltage fluctuations and prevents latch-up during intermittent shorts.

Use Scenario: Powering trailer brake lights, marker lamps, and turn signals in heavy-duty truck/trailer systems.

IC Role / Device Role / Timing Role: Automotive-grade switch supporting wide input range (4.5–28 V), reverse-battery tolerance, and EMC-optimized emissions.

Use Value: Meets ISO 11452-2/4 and CISPR 25 Class 5 requirements out-of-the-box, reducing validation time.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (160 mΩ), no analog current sense, integrated watchdog timer	Lacks proportional current feedback; suited for simpler on/off control where diagnostics are handled externally	Select when system-level current monitoring is performed via shunt + ADC, not device-native sense
IPS1021H	Lower current limit (12 A), 3.3 V logic only, no CS_DIS pin	Targeted at lower-power body electronics; lacks open-load detection in OFF state	Choose for cost-sensitive non-safety applications where thermal margin and diagnostic depth are reduced

Compared with VN5E050AJTR-E, TPS4H160-Q1 trades analog sensing for enhanced functional safety features, while IPS1021H reduces integration depth to meet entry-level automotive cost targets-neither replicates the combination of 27 A current limit, 50 mΩ R_ON, and full diagnostic suite in PowerSSO-12.

FAQ

What is the purpose of the CS_DIS pin?

The CS_DIS pin is an active-high CMOS-compatible input that disables the analog current sense output. When pulled high, it disconnects the internal sense amplifier, allowing multiple VN5E050AJTR-E devices to share a single external sense resistor-reducing BOM count and PCB footprint in multi-channel systems.

How does the device handle reverse battery conditions?

VN5E050AJTR-E is reverse-battery protected per Figure 32: the GND pin must be connected through an external diode or resistor network to prevent damage. Internally, it features ESD protection (2000 V on CURRENT SENSE) and withstands -0.3 V on VCC, but full reverse-battery survival requires proper external GND-line protection as specified in Section 3.1.

Can this driver replace mechanical relays in automotive applications?

Yes-VN5E050AJTR-E replaces electromechanical relays in 12 V automotive loads up to 27 A, offering faster switching (20/40 µs), no contact wear, integrated diagnostics, and superior EMC performance. Its PowerSSO-12 package supports higher cycle life and smaller form factor than relay-based solutions.

What is the maximum demagnetization energy rating?

The device supports up to 104 mJ of demagnetization energy (single pulse, L = 3 mH, V_bat = 13.5 V, T_j,start = 150°C), enabling reliable turn-off of highly inductive solenoids and actuators without external snubbers or freewheeling diodes.
