Product details

Overview

VN5E025AJ-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 60 A short-circuit current limit, 25 mΩ on-resistance at 25°C, and operates across 4.5–28 V supply for 12 V grounded loads including LEDs, solenoids, and relays.

For engineers reviewing the VN5E025AJ-E datasheet, VN5E025AJ-E pinout, VN5E025AJ-E application, or VN5E025AJ-E equivalent, key selection criteria include diagnostic accuracy over wide load currents (0.05–10 A), thermal shutdown with auto-restart, reverse-battery protection compatibility, and off-state open-load detection capability.

Technical Context

The device implements active power limitation to manage inrush and sustained overloads, dynamically clamping output voltage to limit I²R dissipation while maintaining precise current sensing via proportional ISENSE output. Its VIPower M0-5 process enables integrated protection against undervoltage (4.5 V trip), overvoltage (41 V clamp), loss of ground/VCC, and fast thermal transients.

Diagnostic functions are hardware-synchronized: CS_DIS enables shared external sense resistor usage; OFF-state open-load detection triggers at VOUT > 2 V; short-to-VCC is identified by delayed VOUT collapse during turn-off; thermal shutdown (150°C) includes hysteresis (7°C) and autorestart behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands automotive load-dump transients without external clamp
Operating voltage range	4.5–28 V - supports cold-crank (4.5 V) and boosted battery conditions
On-state resistance	25 mΩ @ 25°C - minimizes conduction loss for 3 A continuous load (≤225 mW)
Current limit (typ)	60 A - limits peak fault current to protect wiring and upstream fuses
Standby current	2 µA - enables always-on modules without battery drain
Current sense ratio	1990–4930 A/A (K₀–K₃) - provides scalable analog feedback for MCU ADC with <±10% drift over -40 to 150°C
Thermal shutdown	150°C with 7°C hysteresis - prevents permanent damage while enabling recovery after fault clearance

Pinout & Package

Package: PowerSSO-12 - surface-mount, thermally enhanced 12-pin package with exposed die-pad connected to VCC for low R_thj-case (1.4°C/W).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; connects to exposed pad for thermal conduction; rated to 41 V DC
OUTPUT	High-side switched output	Drives grounded loads; integrates active voltage clamp and current limiting
GND	Ground reference	Must be reverse-battery protected externally (diode/resistor network per Fig 3)
INPUT	CMOS-compatible control input	Hysteresis-enabled (0.25 V), 3.0/5.0 V logic compatible; drives internal power MOSFET gate
CURRENT SENSE	Analog current feedback output	Delivers ISENSE = IOUT / K (K = 1990–4930); usable up to 5 V output with 1 µA leakage
CS_DIS	Current sense enable/disable	Active-high CMOS input; disables ISENSE output when pulled high, enabling shared sense resistor topology

Key Features

Feature	Design Value
Inrush current management	Power limitation architecture actively controls dI/dt and peak current during cold-start load engagement
Proportional analog current sense	Multi-point calibrated K-ratio (K₀–K₃) ensures ±10% full-scale accuracy from 0.05 A to 10 A across temperature
Off-state open-load detection	Detects open circuit at OUTPUT when INPUT = 0 V and VOUT > 2 V, enabling fail-safe diagnostics
Short-to-VCC detection	Identifies output shorted to battery via delayed VOUT collapse (>180 µs) during turn-off transition
Reverse battery protection support	Integrated GND pin ESD structure allows external diode/resistor network (per Section 3.1) to block reverse-current damage

Applications

Use Scenario: Controlling fuel injector or turbocharger VGT solenoids requiring precise energization timing and coil demagnetization energy handling.

IC Role / Device Role / Timing Role: High-side driver with V_DEMAG clamp (VCC−41 V) and 140 mJ max switching energy rating for inductive kickback suppression.

Use Value: Integrated clamp eliminates need for external TVS; power limitation prevents thermal runaway during stuck-open faults.

Electric Power Steering Motor Enable

Use Scenario: Managing multiple resistive/inductive loads (windows, mirrors, seats) with centralized diagnostics and fuseless protection.

IC Role / Device Role / Timing Role: Single-channel protected switch providing ON/OFF control, current feedback, and open-load reporting to MCU.

Use Value: 2 µA standby current enables always-on BMS functionality; CS_DIS pin allows multiplexed current sensing across 4+ channels.

Use Value: 150°C shutdown with autorestart ensures temporary overload recovery without system reset; 4.5 V undervoltage lockout prevents erratic operation during cranking.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS27081AQPWPRQ1	Lower current limit (5.5 A), no analog current sense, 1.2 V logic-compatible input	Suitable for low-power body electronics only; lacks diagnostic granularity for safety-critical loads	Select when cost and footprint are prioritized over diagnostic fidelity and high-current capability
IPS1025H	Higher R_ON (40 mΩ), identical 60 A current limit, same PowerSSO-12 package, no CS_DIS pin	Matches thermal performance but requires dedicated sense resistor per channel	Choose when shared current sensing is unnecessary and higher conduction loss is acceptable

Compared with VN5E025AJ-E, TPS27081AQPWPRQ1 trades diagnostic depth and current capacity for lower voltage operation and smaller size, while IPS1025H matches protection level but sacrifices current sense flexibility and adds conduction loss-making VN5E025AJ-E optimal for systems needing precision analog feedback and multi-device sensing coordination.

FAQ

What is the maximum continuous output current rating for VN5E025AJ-E?

The device does not specify a continuous current rating independent of thermal conditions. Its 60 A value is a short-circuit current limit under power limitation. Continuous current depends on PCB copper area, ambient temperature, and airflow-typically 3–5 A with 250 mm² 2-oz copper and 25°C ambient, based on R_thj-amb curves in Figure 36.

How does the current sense disable (CS_DIS) function affect diagnostic coverage?

When CS_DIS is high, the CURRENT SENSE pin is disabled and sinks <1 µA, eliminating analog feedback. All diagnostics dependent on ISENSE-such as overload indication, short-to-ground detection, and current measurement-are suspended. Open-load detection remains functional as it relies on OUTPUT voltage monitoring, not current sense.

Can VN5E025AJ-E drive inductive loads without external flyback components?

Yes-the device integrates an active overvoltage clamp that limits V_OUT to VCC−41 V during turn-off, absorbing demagnetization energy up to 140 mJ (L=0.8 mH, V_BAT=13.5 V). This eliminates need for external TVS or diodes in most automotive solenoid and relay applications.

What is the minimum input voltage required to guarantee turn-on at cold-crank conditions?

The INPUT pin requires VIH ≥ 2.1 V for guaranteed logic high. With VCC as low as 4.5 V during cold crank, the 3.0 V CMOS-compatible input threshold and 0.25 V hysteresis ensure noise-immune activation. No level-shifting is needed between standard 3.3 V or 5 V MCUs and the driver input.
