Product details

Overview

VN5E050J-E from STMicroelectronics is a single-channel automotive high-side driver in PowerSSO-12 package, delivering 27 A current limiting, 50 mΩ on-resistance at 25°C, and integrated diagnostics including open-load detection (ON/OFF state), short-to-VCC indication, and thermal shutdown with auto-restart - used to control resistive/inductive loads such as solenoids, relays, and lamps in body electronics modules.

For engineers reviewing the VN5E050J-E datasheet, VN5E050J-E pinout, VN5E050J-E application, or VN5E050J-E equivalent, key selection criteria include CMOS-compatible 3.0 V input logic, reverse-battery protection support, ISO 7637-2 pulse immunity (Class C), and diagnostic feedback via open-drain STATUS pin with STAT_DIS disable control.

Technical Context

The VN5E050J-E integrates VIPower M0-5 technology to combine power MOSFET switching with real-time protection logic, enabling active power limitation during inrush and overload events. Its diagnostic architecture uses dedicated voltage/current thresholds to distinguish ON-state open load (I_OL = 10–70 mA), OFF-state open load (V_OL = 2–4 V), and short-to-VCC (t_DSTKON ≤ 1200 µs).

Thermal management employs self-limiting fast transients and overtemperature shutdown at 150–200°C with 135°C restart threshold and 7°C hysteresis. Protection functions operate independently of microcontroller intervention, with undervoltage lockout at 3.5–4.5 V and overvoltage clamp up to 52 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands load dump pulses per ISO 7637-2 Pulse 5b (up to +87 V with external clamp)
Operating voltage range	4.5 V to 28 V - supports 12 V and 24 V automotive battery systems across cold-crank and alternator regulation
On-state resistance	50 mΩ (typ, 25°C) - enables <1.3 W conduction loss at 5 A, critical for thermally constrained PCB layouts
Current limitation	27 A (typ) - limits fault energy during short-to-ground, reducing required heatsinking and system-level fusing
Off-state supply current	2 µA (typ) - ensures <10 µA total system quiescent draw in sleep mode for compliance with ISO 16750-2 low-power requirements
Status pin type	Open-drain with 0.5 V max low-level voltage at 1.6 mA - allows wired-OR diagnostics across multiple channels without level-shifting
Input logic compatibility	3.0 V CMOS - interfaces directly with 3.3 V microcontrollers without external level translation

Pinout & Package

Package: PowerSSO-12 - surface-mount, exposed pad for thermal dissipation, footprint optimized for automotive-grade reflow profiles and mechanical robustness under vibration.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4.5–28 V DC; clamped to 52 V during transients; connects to PCB power plane with local 100 nF decoupling
OUTPUT	High-side switched output	Drives grounded loads; rated for 27 A continuous with internal current limiting and demagnetization energy handling (EMAX = 104 mJ)
GND	Ground reference	Must be reverse-battery protected externally (diode/resistor network per Figure 32); shared return path for logic and power sections
INPUT	CMOS-compatible control input	Hysteresis (0.25 V) prevents noise-induced switching; accepts 0.9 V low / 2.1 V high thresholds for 3.3 V MCU interfacing
STATUS	Diagnostic open-drain output	Reports overload, overtemperature, open load, and short-to-VCC; pulled high externally to enable wired-OR configuration
STAT_DIS	Active-high status disable	Pulling high disables STATUS output (high-Z), allowing multi-device diagnostic bus sharing without contention

Key Features

Feature	Design Value
Inrush current active management	Power limitation algorithm dynamically adjusts output voltage slope (dV/dt) to limit peak inrush into capacitive loads without external components
Enhanced open-load detection	Distinguishes ON-state (current-based, 10–70 mA threshold) and OFF-state (voltage-based, 2–4 V threshold) faults independently, eliminating need for external sense resistors
Reverse battery protection support	Integrated input clamp and GND pin design allow external diode/resistor network (per Figure 32) to block -14 V reverse polarity without device damage
ISO 7637-2 Class C immunity	Passes all five test pulses (including Pulse 5b up to +87 V with external clamp), ensuring reliable operation in harsh automotive electrical environments
Auto-restarting thermal shutdown	Shuts down at 150–200°C junction temperature and resumes operation after cooling to 135–140°C, preventing latch-up during intermittent overloads

Applications

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), lower ILIM (10 A), integrated charge pump for 3.3 V logic drive	Targeted at lower-current solenoid valves; lacks OFF-state open-load detection and STAT_DIS disable	Select when board space is constrained and diagnostic depth is secondary to ultra-low quiescent current (50 nA)
BDL1012	Lower voltage rating (28 V max), no integrated overvoltage clamp, requires external status pull-up	Suitable for non-automotive 12 V industrial loads; fails ISO 7637-2 Pulse 5b without external TVS	Choose only for cost-sensitive non-automotive designs where load dump immunity is not required

Compared with TPS4H160-Q1 and BDL1012, the VN5E050J-E provides superior fault coverage (ON/OFF open-load, short-to-VCC, auto-restart thermal), higher surge tolerance (41 V continuous, 87 V pulsed), and diagnostic flexibility (STAT_DIS disable), making it optimal for ASIL-B body electronics requiring full diagnostic traceability.

FAQ

What is the maximum continuous output current rating for VN5E050J-E?

The VN5E050J-E is rated for 27 A typical current limitation under short-circuit conditions at VCC = 13 V and Tj = 25°C. Continuous DC current capability depends on PCB thermal design: with 250 mm² copper area (2 oz), it supports ~8 A continuous; with 1000 mm², up to ~14 A. Derating curves are provided in Figure 36 of the datasheet.

Does VN5E050J-E require an external flyback diode for inductive loads?

No external flyback diode is required. The device integrates an active voltage clamp that limits VOUT to VCC − 41 V during inductive turn-off (demagnetization), handling up to 104 mJ of switching energy (L = 3 mH, Vbat = 13.5 V). This eliminates external diodes in most automotive solenoid and relay applications.

How does the STATUS pin indicate overtemperature condition?

When junction temperature exceeds TTSD (150–200°C), the STATUS pin goes low after a 20 µs delay (tSDL) and remains low until Tj falls below TR (135–140°C). During thermal cycling, the STATUS pin toggles low/high with hysteresis, enabling software to implement thermal foldback or forced shutdown without external temperature sensors.

Can VN5E050J-E be used in 24 V commercial vehicle applications?

Yes. Its 4.5–28 V operating range and 41 V absolute maximum VCC rating cover 24 V nominal systems, including cold-crank down to 6 V and load dump up to 40 V (with external clamp per Figure 32). It meets ISO 16750-2 and ISO 7637-2 requirements for commercial vehicles when implemented with recommended PCB layout and protection networks.
