Product details

Overview

VN5E050MJ-E from STMicroelectronics is a single-channel automotive high-side driver in PowerSSO-12 package, integrating VIPower™ M0-5 technology. It delivers 27 A current limiting, 50 mΩ on-resistance at 25°C, and analog current sense with ±10% ratio drift over temperature. Designed for 12 V grounded loads, it enables precise diagnostics and protection in LED lighting, solenoid control, and body electronics.

For engineers reviewing the VN5E050MJ-E datasheet, VN5E050MJ-E pinout, VN5E050MJ-E application, or VN5E050MJ-E equivalent, key selection criteria include CMOS-compatible 3.0 V input logic, reverse-battery protection capability, thermal shutdown with auto-restart, and proportional current sense accuracy across 0.05–4 A load range.

Technical Context

The device implements active power limitation to manage inrush and overload conditions, with fast thermal transient self-limiting and overvoltage clamp up to 52 V. Its diagnostic architecture provides real-time analog current sense (K₀ = 2000 typ.) and fault indication via voltage drop limitation (V_ON ≤ 25 mV) and thermal shutdown at 150°C.

Protection functions include undervoltage shutdown (4.5 V threshold), loss-of-ground/loss-of-V_CC detection, and ESD robustness (4 kV HBM on IN/CS pins). The CS_DIS pin allows hardware disable of current sensing to share external sense resistors across multiple channels.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - supports automotive load-dump transients without external clamping
Operating voltage range	4.5 V to 28 V - ensures reliable operation across cold-crank (4.5 V) and boosted battery (28 V)
On-state resistance	50 mΩ @ 2A, 25°C - limits conduction loss to ≤200 mW at 2 A, enabling compact thermal design
Current limit (typ)	27 A @ 13 V - sustains short-circuit events while maintaining safe junction temperature
Off-state supply current	2 µA @ 13 V - minimizes standby drain in always-on vehicle modules
Current sense ratio	2000 typ. (I_OUT/I_SENSE) - enables accurate 0.5–4 A sensing with standard 3.9 kΩ resistor
Thermal shutdown	150°C with 135°C auto-restart - prevents permanent damage during sustained overload

Pinout & Package

Delivered in the thermally enhanced PowerSSO-12 surface-mount package with exposed die-pad (TAB = V_CC) for low R_thj-case (2.7 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Battery supply input	Accepts 4.5–28 V DC; internal clamp protects against 41 V transients
OUT	High-side power output	Drives grounded loads; features V_ON limitation (≤25 mV) and reverse-battery diode (V_F = 0.7 V)
GND	Ground reference	Must be externally protected against reverse battery using diode/resistor network per Figure 29
IN	CMOS-compatible control input	3.0 V logic compatible; 0.9 V low / 2.1 V high thresholds with 0.25 V hysteresis
CS	Analog current sense output	Sinks proportional current (I_SENSE = I_OUT/2000); max 5 V output with 9 mA fault current
CS_DIS	Current sense enable/disable	Active-high CMOS input; disables CS when pulled ≥2.1 V, allowing shared sense resistor topology

Key Features

Feature	Design Value

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, SPI interface only	Lacks proportional analog sense; requires MCU with SPI and firmware for diagnostics	Choose when digital bus integration outweighs need for analog feedback simplicity
IPS1025H	Lower current limit (25 A), same PowerSSO-12, but no CS_DIS pin or reverse-battery GND protection	Requires external reverse-battery network; less flexible current sense sharing	Prefer when cost sensitivity dominates and shared sense resistor topology is unnecessary

Compared with TPS4H160-Q1 and IPS1025H, the VN5E050MJ-E uniquely combines analog current sense with hardware CS_DIS control and integrated reverse-battery GND protection-enabling simpler, more robust designs for safety-critical automotive loads without added components or firmware overhead.

FAQ

What is the maximum continuous output current supported by VN5E050MJ-E?

The device does not specify a continuous current rating due to thermal dependence on PCB layout and ambient conditions. Its 27 A current limit is a short-circuit threshold under defined test conditions (V_CC = 13 V). Continuous current capability is determined by junction temperature rise-typically 5–7 A with 25 cm² copper pour and forced airflow, per Figure 33 thermal data.

Can VN5E050MJ-E drive inductive loads without external flyback protection?

Yes-the device integrates an active overvoltage clamp that limits V_OUT to 41–52 V during inductive turn-off, eliminating the need for external flyback diodes in most automotive solenoid and relay applications. Maximum demagnetization energy is rated at 104 mJ (L = 3 mH, V_bat = 13.5 V), verified per Figure 31.

How does the CS_DIS pin affect current sense accuracy and timing?

When CS_DIS is high (≥2.1 V), the internal current sense amplifier is disabled, reducing I_SENSE leakage to ≤1 µA and removing propagation delay (Δt_DSENSE2H = 40 µs). This allows multiple VN5E050MJ-E devices to share one external sense resistor without cross-talk or offset accumulation.

Is VN5E050MJ-E compliant with AEC-Q100 qualification standards?

Yes-the device is qualified per AEC-Q100 Grade 1 (–40°C to +125°C ambient) and supports junction temperatures up to +150°C. It meets automotive EMC requirements per ISO 11452-2/4/5 and transient immunity per ISO 7637-2 Pulses 1, 2a, 3a/b, and 5a, as validated in ST's application note AN4737.
