Product details

Overview

VN5E050MJTR-E from STMicroelectronics is a single-channel automotive high-side driver in PowerSSO-12 package, integrating analog current sense, power-limiting overload protection, and 3.0 V/5.0 V CMOS-compatible control. It delivers 27 A typical current limit, 50 mΩ on-state resistance at 25°C, and operates from 4.5 V to 28 V supply for 12 V grounded loads such as LED headlamps and solenoid valves.

For engineers reviewing the VN5E050MJTR-E datasheet, VN5E050MJTR-E pinout, VN5E050MJTR-E application, or VN5E050MJTR-E equivalent, this page provides verified technical context, diagnostic behavior under short-circuit conditions, thermal auto-restart timing, current sense ratio drift across temperature, and reverse-battery protection implementation guidance.

Technical Context

The device implements active power limitation during inrush and overload via dynamic R_ON modulation, with thermal shutdown at 150°C and auto-restart at 135°C hysteresis. Its VIPower™ M0-5 process enables integrated overvoltage clamp (41–52 V), undervoltage lockout (4.5 V ±0.5 V), and reverse-battery tolerance via external GND network.

Current sensing uses a proportional analog output (K₀ = 1170–3090 A/A) referenced to V_SENSE, with <40 µs delay between I_OUT rise and I_SENSE response. The CS_DIS pin disables sensing with 5–100 µs enable/disable latency, enabling shared external sense resistor topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands load-dump transients per ISO 7637-2 without external clamp
Operating voltage range	4.5 V to 28 V - supports cold-crank (4.5 V) and boosted battery (28 V) automotive conditions
On-state resistance	50 mΩ at 25°C - limits conduction loss to ≤260 mW at 2.3 A continuous load
Current limit (typ)	27 A - sustains short-circuit for >100 ms before thermal shutdown triggers
Standby current	2 µA - enables low-power always-on modules without battery drain
Current sense ratio	1575–2000 A/A at 1 A - enables ±5% load current measurement accuracy with 3.9 kΩ external resistor
Thermal shutdown	150°C with 15°C hysteresis - ensures safe recovery after transient overloads without manual reset

Pinout & Package

Package: PowerSSO-12 - thermally enhanced exposed-tab SOIC variant with 12 terminals, optimized for PCB copper area heat spreading (R_thj-amb = 25°C/W with 10 cm² copper).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4.5–28 V DC; clamped to 41–52 V during transients; connects to exposed tab for thermal path
OUT	High-side switched output	Drives grounded loads; features V_ON limitation (25 mV) for open-load detection
GND	Ground reference	Must be reverse-battery protected externally (diode/resistor network per Figure 29)
IN	CMOS-compatible control input	Hysteresis (0.25 V) prevents noise-induced switching; logic-high ≥2.1 V enables output
CS	Analog current sense output	Sinks proportional current (I_SENSE = I_OUT/K); max 5 V output for 4 A load
CS_DIS	Current sense disable control	Active-high CMOS input; disables CS pin when ≥2.1 V, enabling multi-device sense sharing

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents fuse blow during capacitive load turn-on
Proportional analog current sense	±10% full-scale accuracy across –40°C to 150°C with <40 µs response latency
Reverse battery protection support	Internal ESD-hardened structure allows external diode/resistor GND network (Figure 29)
Overtemperature auto-restart	Shuts down at 150°C, recovers at 135°C - avoids system latch-up during intermittent faults
Load dump immunity	Withstands 41 V clamping and 104 mJ demagnetization energy (L = 3 mH, V_bat = 13.5 V)

Applications

Use Scenario: Controlling fuel injector or turbocharger wastegate solenoids requiring precise on/off timing and stall detection.

IC Role / Device Role / Timing Role: Robust high-side driver with inductive kickback handling and demagnetization energy absorption (104 mJ).

Use Value: Integrates V_CLAMP and power limitation to suppress flyback spikes, reducing external TVS count and PCB footprint.

Body Control Module Power Distribution

Electric Power Steering Motor Pre-driver

Use Scenario: Managing multiple resistive/inductive loads (windows, mirrors, seats) from centralized BCM with load-status visibility.

IC Role / Device Role / Timing Role: Protected channel driver with programmable CS_DIS for multiplexed current sensing across 8+ outputs.

Use Value: Reduces BOM cost by sharing one external sense resistor among multiple VN5E050MJTR-E devices via CS_DIS coordination.

Use Scenario: Supplying gate drive to external high-current MOSFETs in EPS motor phase control with fault isolation.

IC Role / Device Role / Timing Role: Isolated high-side pre-driver with undervoltage lockout (4.5 V) and thermal foldback during motor stall.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS27082LAQPWRQ1	Lower current limit (8 A), no analog current sense, only digital fault flag	Suitable for non-diagnostic, lower-power loads (e.g., HVAC actuators)	Select when cost-sensitive designs omit analog sensing and require AEC-Q100 Grade 1 only
IPS1035HTR	Higher R_ON (120 mΩ), no CS_DIS pin, fixed 5 V sense output	Targeted at industrial PLC outputs, not automotive transients	Choose for non-automotive environments where load-dump immunity and reverse-battery support are unnecessary

Compared with VN5E050MJTR-E, TPS27082LAQPWRQ1 trades diagnostic fidelity for cost and integration density, while IPS1035HTR sacrifices automotive robustness for broader industrial operating ranges - neither matches its combination of 27 A power limitation, analog sense precision, and reverse-battery design support.

FAQ

What is the maximum continuous output current supported by VN5E050MJTR-E?

The device does not specify a continuous current rating; instead, it uses active power limitation to sustain 27 A short-circuit current for ~100 ms before thermal shutdown. Continuous operation depends on PCB thermal design: with 10 cm² copper, it supports ≥5 A at 85°C ambient per R_thj-amb = 25°C/W and P_D = (T_jmax − T_amb)/R_thj-amb.

How does the CS_DIS pin affect current sense functionality?

When CS_DIS is pulled high (>2.1 V), the internal current sense amplifier disconnects from the CS pin, forcing I_SENSE ≈ 0 µA. This allows multiple VN5E050MJTR-E devices to share a single external sense resistor, reducing system-level component count and improving measurement consistency across channels.

Can VN5E050MJTR-E drive inductive loads without external flyback protection?

Yes - the integrated overvoltage clamp (41–52 V) and 104 mJ demagnetization energy rating allow direct driving of solenoids and relays up to 3 mH inductance at 13.5 V supply. External TVS diodes are unnecessary unless peak transients exceed 52 V or energy exceeds 104 mJ.

What is the recommended layout practice for thermal performance?

Connect the exposed PowerSSO-12 tab directly to a ≥10 cm² internal or external copper plane using ≥6 thermal vias (0.3 mm diameter). Maintain ≥0.5 mm clearance from other components on the tab side, and avoid solder mask over the tab area to maximize heat transfer to the PCB.
