Product details

Overview

VND5E050AJTR-E from STMicroelectronics is a dual-channel automotive high-side driver IC in PowerSSO-24 package, delivering 27 A typical current limitation per channel, 50 mΩ on-state resistance at 25°C, and proportional analog current sense (K₀ = 2250 typ) for real-time load monitoring. It drives grounded resistive/inductive/capacitive loads in 12 V vehicle systems with integrated diagnostics including off-state open-load detection, short-to-VCC reporting, and thermal shutdown with auto-restart.

For engineers reviewing the VND5E050AJTR-E datasheet, VND5E050AJTR-E pinout, VND5E050AJTR-E application, or VND5E050AJTR-E equivalent, this page provides verified technical context, validated pin functions, confirmed automotive diagnostic behavior, and real-world design meaning for load management, fault reporting, and ESD-hardened interface compatibility with 3.0 V CMOS microcontrollers.

Technical Context

This device implements two independent VIPower M0-5 high-side switches with active power limitation for inrush and overload control, each featuring dedicated analog current sense pins (CS1/CS2) delivering I_SENSE = I_OUT/K₀ (2250 typ), and a shared CS_DIS input to disable sensing. Diagnostics include voltage-based short-to-VCC detection, current-based off-state open-load identification, and thermal shutdown at 150°C with 135°C auto-restart threshold.

Protection architecture integrates undervoltage lockout (4.5 V trip), overvoltage clamp (46 V typ), reverse-battery tolerance via external GND network, and self-limiting fast thermal transients. The logic inputs accept 3.0 V CMOS-compatible signals with 0.25 V hysteresis and ±1 mA input current limits, ensuring robust MCU interfacing under automotive transients.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands ISO 7637-2 Load Dump pulse without external clamp
Operating voltage range	4.5–28 V - supports cold-crank (4.5 V) and boosted battery (28 V) conditions
On-state resistance (per ch.)	50 mΩ @ 25°C - enables <260 mW conduction loss at 2.3 A continuous load
Current limit (typ)	27 A - sustains short-circuit events while limiting peak power dissipation
Standby supply current	2 µA - minimizes parasitic drain in always-on vehicle modules
Current sense ratio (K₀)	2250 typ - delivers 444 nA/A output current for precise 12-bit ADC digitization
Thermal shutdown	150°C with 135°C auto-restart - prevents latch-up during intermittent overload

Pinout & Package

Package: PowerSSO-24 (exposed thermal pad tied to VCC), RoHS-compliant, ECOPACK® certified.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; connects to exposed thermal pad for enhanced heat dissipation
GND	Ground reference	Must be protected against reverse battery via external diode/resistor network per Figure 32
INPUT1 / INPUT2	CMOS-compatible control inputs	3.0 V logic compatible; 0.25 V hysteresis prevents noise-induced switching
OUTPUT1 / OUTPUT2	High-side switched outputs	Drive grounded loads; integrate reverse-battery protection diode (VF = 0.7 V @ 4 A)
CURRENT SENSE1 / CURRENT SENSE2	Analog current feedback outputs	Deliver I_SENSE = I_OUT/2250; enable real-time load monitoring and fault classification
CS_DIS	Current sense disable control	Active-high CMOS input; disables both CS1/CS2 to share external sense resistor across multiple devices

Key Features

Feature	Design Value
Inrush current active management	Power limitation circuitry dynamically caps dI/dt during turn-on, reducing peak stress on wiring harnesses and connectors
Proportional analog current sense	±15% full-scale accuracy across -40°C to +150°C enables closed-loop load regulation without external shunt amplifiers
Off-state open load detection	Validated at 8–18 V VCC; distinguishes open circuit from high-impedance leakage using controlled current injection
Short-to-VCC detection	Identifies output shorted to battery via voltage threshold comparison during OFF state, independent of load type
Reverse battery protection support	Internal structure tolerates -0.3 V on VCC; requires external GND-line protection (diode or resistor) per Figure 32

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE7232G	Single-channel, 60 mΩ R_ON, no analog current sense (digital flag only), 40 V max V_CC	Lacks per-channel analog sensing; suitable only where binary fault reporting suffices	Select when cost sensitivity outweighs need for current telemetry and dual-channel integration
VND5E025AKTR-E	Same PowerSSO-24 package, 25 mΩ R_ON, 45 A current limit, identical pinout and diagnostic set	Higher conduction efficiency and overload margin; shares same layout and firmware interface	Choose for higher-current loads (e.g., radiator fans) without redesigning PCB or software

Compared with TLE7232G, VND5E050AJTR-E provides true analog current telemetry and dual-channel integration; compared with VND5E025AKTR-E, it trades lower R_ON for higher thermal robustness at 50 mΩ, making it optimal for thermally constrained modules where 27 A limiting aligns with system fuse ratings.

FAQ

What is the function of the CS_DIS pin?

The CS_DIS pin is an active-high CMOS-compatible input that disables both CURRENT SENSE1 and CURRENT SENSE2 outputs simultaneously. When pulled high (≥2.1 V), it disconnects internal sense circuitry, allowing external current-sense resistors to be shared across multiple VND5E050AJTR-E devices-reducing system-level component count and PCB footprint without sacrificing diagnostic flexibility.

How does off-state open load detection work?

Off-state open load detection operates by injecting a small test current into the OUTPUT pin while the channel is disabled. If no return path exists (i.e., open circuit), the resulting voltage rise triggers a diagnostic flag. This function is validated across 8–18 V V_CC and works reliably with resistive, inductive, and capacitive loads-enabling early detection of broken wires or disconnected actuators before system startup.

Can VND5E050AJTR-E drive inductive loads like fuel injectors?

Yes. The device supports demagnetization energy up to 104 mJ (L = 3 mH, V_BAT = 13.5 V) and features active V_CLAMP (46 V typ) to suppress flyback voltage spikes. Its integrated reverse-battery protection and -40°C to +150°C junction temperature range make it suitable for direct fuel injector control in engine control units without external snubbers or clamps.

What thermal management is required for continuous 20 A operation?

At 20 A continuous per channel, power dissipation reaches ~2 W per channel (20² × 0.05 Ω). With PowerSSO-24's R_thj-case = 2.7 °C/W and recommended 500 mm² copper pour, junction temperature rise stays below 100°C above ambient-well within the 150°C shutdown threshold. No heatsink is required if PCB layout follows ST's AN4737 guidelines for thermal vias and copper area.
