Product details

Overview

VN5025AJTR-E from STMicroelectronics is a single-channel automotive high-side driver with integrated analog current sense, designed for driving resistive, inductive, or capacitive loads connected to ground. It features 25 mΩ on-state resistance (R_ON), 40 A typical current limitation (I_LIMH), ±12% current sense ratio drift over temperature and load, and operates across 4.5–36 V supply range - enabling robust LED and solenoid control in engine bay and body electronics.

For engineers reviewing the VN5025AJTR-E datasheet, VN5025AJTR-E pinout, VN5025AJTR-E application, or VN5025AJTR-E equivalent, key selection criteria include its PowerSSO-12 package thermal performance, CMOS-compatible 3.0 V input logic, reverse battery protection capability, and proportional current sense accuracy across –40°C to +150°C junction temperature.

Technical Context

This device implements VIPower M0-7 technology to integrate power MOSFET, protection circuitry, and analog current sensing in a single monolithic die. Its active V_CC clamp (41 V max) ensures ISO 7637-2 Pulse 1/2a/3a/3b/5b transient immunity without external TVS, while self-limiting thermal transients prevent destructive latch-up during fast overload events.

The current sense function delivers I_SENSE = I_OUT/K, where K varies from 1420 to 5180 depending on load current and temperature; CS_DIS enables high-impedance disable mode. Thermal shutdown (T_TSD = 150–200°C) includes automatic restart after fault clearance, supporting fail-safe operation in ASIL-B-relevant subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage (V_CC)	41 V - withstands automotive load dump transients per ISO 7637-2 Pulse 5b without external clamping.
Operating voltage range	4.5 V to 36 V - supports cold-crank (4.5 V) and 24 V commercial vehicle systems.
On-state resistance (R_ON)	25 mΩ @ 25°C - limits conduction loss to ≤225 mW at 3 A, enabling compact thermal design.
Current limit (I_LIMH)	40 A typ. - sustains short-circuit conditions while limiting peak power dissipation to safe levels.
Current sense ratio (K)	2010–4160 @ 0.5 A - enables accurate closed-loop load monitoring with <±12% drift over full temp/load range.
Standby supply current (I_S)	2 µA - minimizes battery drain in always-on modules such as door control units.
Thermal shutdown threshold	150°C min. - triggers automatic recovery upon cooling, avoiding permanent latch-off in intermittent faults.

Pinout & Package

Delivered in PowerSSO-12 surface-mount package with exposed thermal pad (TAB = V_CC), optimized for PCB copper area heat spreading in automotive under-hood environments.

Pin/Terminal	Circuit Role	Design Meaning
V_CC (Pins 1,2,12)	Battery supply input	Three parallel pins reduce IR drop and improve current handling; connects to internal clamp diode and power stage.
OUTPUT (Pin 3)	High-side switched output	Drives load between this pin and GND; rated for 40 A short-circuit current and reverse battery tolerance via external network.
GND (Pin 4)	Ground reference	Must be protected against reverse battery using external diode/resistor network per Figure 26.
INPUT (Pin 5)	CMOS-compatible control input	3.0 V logic compatible with microcontroller GPIO; includes 0.25 V hysteresis for noise immunity.
CURRENT SENSE (Pin 6)	Analog current mirror output	Delivers I_SENSE = I_OUT/K; requires external sense resistor to convert to voltage for ADC sampling.
CS_DIS (Pin 7)	Current sense enable/disable	Active-high CMOS input; drives CURRENT SENSE pin to high-Z when high, eliminating leakage path during sleep.

Key Features

Feature	Design Value
Inrush current management	Power limitation circuitry prevents voltage sag during capacitive load turn-on, avoiding MCU brownout.
Proportional analog current sense	Real-time I_OUT monitoring with calibrated K-ratio and <200 ns delay response enables precise diagnostics.
Reverse battery protection support	Integrated architecture allows external GND-line diode/resistor network (per Figure 26) to block –14 V faults.
Low EMI emission & high EMS	Optimized switching edge rates (dV/dt controlled) and layout-aware design meet CISPR 25 Class 5 requirements.
Thermal shutdown with auto-restart	Enables self-healing behavior in intermittent overloads - no firmware reset required for recovery.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS50085-1TAD	Higher R_ON (35 mΩ), lower I_LIMH (35 A), no analog current sense - uses digital diagnostic flag only.	Lacks proportional current feedback; suitable where only open-load/short-circuit detection is needed.	Select when cost sensitivity outweighs need for analog diagnostics; requires external sense resistor for current measurement.
NXP MC33883	Lower voltage rating (28 V max), integrated charge pump, SPI interface - not pin-compatible; requires external gate resistor.	Designed for brushed DC motor control with bidirectional current sense; lacks automotive-grade transient immunity.	Prefer for non-automotive industrial motor drivers needing serial configuration; unsuitable for 12/24 V load dump environments.

Compared with VN5025AJTR-E, BTS50085-1TAD trades analog sensing for lower unit cost and simpler layout, while MC33883 offers configurability at the expense of automotive qualification and transient robustness - making VN5025AJTR-E optimal for safety-critical, high-fidelity current monitoring in 12/24 V vehicle platforms.

FAQ

What is the maximum continuous output current for VN5025AJTR-E?

The device does not specify a continuous current rating due to thermal dependence on PCB layout and ambient conditions. Its 40 A current limit (I_LIMH) is a short-circuit threshold; sustained current must be derated based on R_thj-amb (see Figure 29) and maximum junction temperature of 150°C. With 200 cm² copper area, continuous current is ~12 A at 85°C ambient.

How is reverse battery protection implemented with VN5025AJTR-E?

VN5025AJTR-E requires external reverse battery protection on the GND pin, as specified in Section 3.1 of the datasheet. Two validated methods are provided: a series resistor (R_GND) or a Schottky diode (D_GND) in the ground return path. The device itself tolerates –0.3 V on V_CC but cannot block reverse polarity without this external network.

Can the current sense pin be used without an external resistor?

No. The CURRENT SENSE pin delivers a proportional current (I_SENSE), not voltage. An external precision resistor (e.g., 3.9 kΩ per Figure 26) must be placed between this pin and ground to generate a measurable voltage (V_SENSE = I_SENSE × R_SENSE). Without it, no usable analog signal is produced.

Does VN5025AJTR-E support PWM dimming for LED loads?

Yes - its 30 µs turn-on and 50 µs turn-off delays (Table 7) support PWM frequencies up to ~10 kHz with minimal duty-cycle distortion. However, thermal management is critical: LED loads with high peak currents require careful PCB copper design to maintain T_j < 150°C, especially at >5 kHz switching where switching losses dominate.
