Product details

Overview

VND7E025AJTR from STMicroelectronics is a dual-channel automotive smart high-side driver in PowerSSO-16 package, designed for 12 V grounded loads with 3 V/5 V CMOS-compatible control. It delivers 27 mΩ typical on-state resistance per channel, 61 A current limitation, and operates down to 2.85 V supply during cold cranking. Used in ADAS radar power supplies and automotive lamp control.

For engineers reviewing the VND7E025AJTR datasheet, VND7E025AJTR pinout, VND7E025AJTR application, or VND7E025AJTR equivalent, key selection criteria include cranking voltage margin (2.85 V), analog current sense accuracy (±7% at 3 A), latch-off configurability via FaultRST, and AEC-Q100 qualification for under-hood deployment.

Technical Context

This device integrates two independent VIPower M0-7 high-side switches with real-time thermal management and multiplexed analog diagnostics. Each channel features programmable fault latching, dynamic current limiting (ILIMH = 61 A), and shutdown temperature threshold of 150–200 °C with 7 K hysteresis.

The CurrentSense architecture supports four diagnostic modes-load current mirroring (K-factor = 2950 ±7%), short-to-VCC detection, OFF-state open-load (VOL = 2–4 V), and thermal shutdown indication-via a single CS pin controlled by SEn and SEL0 logic inputs.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	4–28 V DC; supports deep cold cranking down to 2.85 V without dropout
On-state resistance	27 mΩ typ. per channel at 3 A/25°C; enables <1 W conduction loss at 10 A
Current limit	61 A typ. DC short-circuit protection; self-limiting during fast thermal transients
Standby current	0.5 µA max. at 13 V/25°C; reduces system quiescent draw in sleep mode
Diagnostic accuracy	±7% current sense error at 3 A; enables precise load monitoring without external calibration
Thermal shutdown	150–200 °C trip range with 7 K hysteresis; prevents irreversible junction damage
ESD rating	4 kV HBM on INPUT/OUTPUT/FaultRST pins; meets automotive robustness requirements

Pinout & Package

Package: PowerSSO-16 - thermally enhanced exposed-tab SO-16 variant optimized for automotive PCBs with 4-layer board R_thj-board = 4.9 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; clamped to 40 V transient; reverse-battery protected externally
GND	Ground reference	Must be reverse-battery protected via external diode/resistor network

SEn	Sense enable control	Active-high; disables CS during low-power mode and enables external resistor sharing
SEL0	Channel select for CS multiplexer	Chooses between Channel 0 or Channel 1 current sense or diagnostic mode
FaultRST	Fault reset/latch control	Active-low; unlatches outputs after fault or forces auto-restart when held low

Key Features

Applications

ADAS Radar Power Supply

Automotive Headlamp Control

Use Scenario: Supplies regulated 12 V power to 77 GHz radar modules requiring stable voltage during engine start.

IC Role / Device Role / Timing Role: High-side switch with cranking support and real-time current monitoring to detect antenna faults.

Use Value: Maintains radar operation below 3 V supply; analog current sense enables predictive maintenance before open-circuit failure.

Use Scenario: Drives LED headlamps with PWM dimming and short-circuit protection in front-end lighting modules.

IC Role / Device Role / Timing Role: Dual-channel load driver with independent diagnostics for left/right beam control.

Use Value: Eliminates need for discrete current-sense resistors and external protection ICs; reduces BOM count by 3 components per channel.

Engine Control Unit (ECU) Solenoid Drive

Body Control Module (BCM) HVAC Actuators

Use Scenario: Controls fuel injector solenoids and EGR valves in harsh under-hood environments.

IC Role / Device Role / Timing Role: High-side driver with thermal shutdown and inductive kickback clamping (V_DEMAG = V_CC − 41 V).

Use Value: Survives repeated 28 V jump-start pulses and 150 °C junction temperatures; eliminates external flyback diodes.

Use Scenario: Powers stepper motor actuators for HVAC blend doors in climate control systems.

IC Role / Device Role / Timing Role: Protected high-side switch with OFF-state open-load detection to verify actuator connection.

Use Value: Detects broken wires or disconnected motors before startup; prevents erroneous HVAC position reporting.

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
TPS4H160-Q1	Higher R_ON (45 mΩ), no integrated current sense; uses digital SPI diagnostics instead of analog CS	Requires external ADC and SPI interface; less suitable for analog feedback loops	Prefer when system already uses CAN/SPI infrastructure and needs configurable fault thresholds
VND7050AJTR	Lower current limit (50 A), same package and pinout; reduced thermal shutdown threshold (140 °C)	Less margin for sustained overload in high-ambient environments	Choose for cost-sensitive applications where peak load current stays below 45 A

Compared with VND7E025AJTR, TPS4H160-Q1 trades analog simplicity for digital configurability, while VND7050AJTR sacrifices thermal headroom and current capability for lower unit cost-neither matches the 2.85 V cranking voltage or ±7% current sense accuracy of the original.

FAQ

What is the minimum supply voltage required for VND7E025AJTR to remain functional during engine cranking?

The device guarantees operation down to 2.85 V when V_CC is decreasing, meeting LV124 Rev. 2013 deep-cranking requirements. Below this threshold, undervoltage shutdown activates and outputs disable until V_CC rises above 3.15 V (2.85 V + 0.3 V hysteresis). This behavior is verified across -40°C to +125°C ambient.

How does the CurrentSense (CS) pin distinguish between normal load current and fault conditions?

The CS pin outputs either a proportional current (I_SENSE = I_OUT/2950) or fixed voltage levels depending on mode: 5–6.6 V indicates thermal shutdown or open-load; near 0 V signals short-to-VCC; and saturation at ~4.8 V occurs during overcurrent. Selection is controlled by SEn and SEL0 logic states per Table 12 of DS11962.

Can VND7E025AJTR drive inductive loads without external flyback components?

Yes-the device integrates an active clamp that limits turn-off voltage to V_CC − 41 V (typ.) during inductive demagnetization, eliminating need for external flyback diodes. This is validated with 6 mH loads and 2 A current, per Table 9's V_DEMAG specification and Figure 9 waveform analysis.

Is the PowerSSO-16 package compatible with standard SO-16 PCB footprints?

No-PowerSSO-16 has a unique thermal pad layout and pin 1 location (top-left corner, not bottom-left). Its exposed metal tab connects to V_CC, requiring dedicated copper pour and thermal vias. Standard SO-16 footprints will misalign pins 1–8 and omit the thermal pad, risking solder joint failure and thermal runaway.
