Product details

Overview

VND5E025AYTR-E from STMicroelectronics is a dual-channel automotive high-side driver in PowerSSO-36 package, designed for 12 V grounded loads with integrated analog current sensing per channel. It delivers 25 mΩ typical on-resistance, 47 A current limitation, and supports 3 V/5 V CMOS-compatible inputs. Used in engine control modules for solenoid and lamp driving where real-time load diagnostics and robust short-circuit protection are required.

For engineers reviewing the VND5E025AYTR-E datasheet, VND5E025AYTR-E pinout, VND5E025AYTR-E application, or VND5E025AYTR-E equivalent, key selection criteria include proportional current sense accuracy (±9% drift over temperature), thermal shutdown with auto-restart, reverse battery protection, and compliance with AEC-Q100 Grade 0 (−40°C to +150°C junction).

Technical Context

The device implements two independent VIPower® M0-5 high-side switches with dedicated analog current sense outputs (CS1/CS2) and a shared CS_DIS enable. Each channel features active power limitation during overload or short-to-ground, with fast response (<100 µs) between output current rise and current sense signal rise.

Protection architecture includes undervoltage shutdown (4.5 V threshold), overvoltage clamp (41–52 V), self-limiting thermal transients, and open-load detection in both ON and OFF states. Diagnostic feedback covers short-to-VCC (180–1200 µs delay), overtemperature (150°C trip), and loss-of-ground/VCC detection.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating voltage range	4.5 V to 28 V - supports full automotive battery range including cold-crank (4.5 V) and load-dump (28 V)
Typical on-resistance (per channel)	25 mΩ at 25°C - enables low conduction loss for 47 A peak current handling
Current limitation (typ)	47 A - limits fault energy during short-to-ground while maintaining safe junction temperature
Standby supply current	2 µA - ensures ultra-low quiescent draw in vehicle sleep modes
Current sense ratio (K₀)	1000–5000 A/A - provides scalable analog feedback for microcontroller-based load monitoring
Thermal shutdown threshold	150°C - triggers auto-restart after cooling to 135°C, enabling fault-tolerant operation
Reverse battery protection	Active MOSFET switch-on at −13 V - prevents system damage without external diodes

Pinout & Package

Package: PowerSSO-36 - thermally enhanced exposed-pad surface-mount package with integrated heat sink capability and AEC-Q100 qualified layout.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VND5E050AKTR-E	50 mΩ R_ON, 50 A current limit, same PowerSSO-36 package	Higher R_ON reduces efficiency in high-current continuous loads but improves thermal margin in sealed enclosures	Select when lower cost and relaxed conduction loss requirements outweigh need for 25 mΩ performance
TPS4H160-Q1	Single-channel, 160 mΩ R_ON, SPI interface, no analog current sense	Lacks per-channel analog sensing; relies on digital diagnostics and external ADC for current monitoring	Choose for systems prioritizing configurability and fault logging over analog feedback simplicity

Compared with VND5E025AYTR-E, the VND5E050AKTR-E trades lower conduction loss for higher thermal robustness, while the TPS4H160-Q1 replaces analog sensing with digital programmability-making the VND5E025AYTR-E optimal for cost-sensitive, analog-diagnostic–driven automotive body and powertrain designs.

FAQ

What is the maximum transient voltage the VND5E025AYTR-E can withstand?

The device supports a maximum transient supply voltage of 41 V on VCC, with an overvoltage clamp operating between 41 V and 52 V depending on current and temperature. This meets ISO 7637-2 Pulse 5a load-dump requirements for 12 V automotive systems without external TVS diodes.

How does the current sense function behave when CS_DIS is asserted?

When CS_DIS is pulled high, both CS1 and CS2 outputs are disabled-halting analog current feedback and reducing leakage to ≤2 µA per sense pin. This allows sharing of a single external sense resistor across multiple VND5E025AYTR-E devices in multi-channel systems, simplifying PCB layout and calibration.

Can the VND5E025AYTR-E drive inductive loads like fuel injectors without external flyback protection?

Yes-the device integrates active demagnetization control and an output voltage clamp (V_DEMAG = V_CC − 39 to V_CC − 52 V) that safely dissipates inductive kickback energy. Tested with L = 6 mH loads at 2 A, it eliminates need for external freewheeling diodes in most automotive solenoid applications.

What is the thermal resistance from junction to case, and how does it impact heatsinking?

R_thj-case is 1.4 °C/W with one channel active, measured with the exposed thermal pad soldered to ≥100 mm² of 2-oz copper. This low value enables direct PCB copper pour heatsinking-no external heatsink required for ≤10 W continuous dissipation per channel in standard automotive ambient conditions.
