Product details

Overview

VND5E025AY-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, 25 mΩ typical on-resistance, 47 A current limitation, and full diagnostic feedback including open-load detection, short-to-VCC indication, and thermal shutdown with autorestart - used in body control modules for headlight and fog lamp switching.

For engineers reviewing the VND5E025AY-E datasheet, VND5E025AY-E pinout, VND5E025AY-E application, or VND5E025AY-E equivalent, key selection criteria include CMOS-compatible 3 V/5 V inputs, proportional current sense ratio (K₀ = 1000–5000), fault response timing (t_DSENSE2H = 70–300 µs), and AEC-Q100-compliant protection architecture for automotive power distribution.

Technical Context

The device implements two independent VIPower® M0-5 high-side switches with dedicated analog current sense outputs (CS1/CS2) delivering I_SENSE proportional to load current across -40°C to 150°C, with K-ratio drift as low as ±3% at 10 A. Each channel features autonomous power limitation during overload or short-to-ground, enabling self-limiting thermal transients without external intervention.

Diagnostic functions are hardware-asserted: OFF-state open-load detection triggers at V_OUT > 2 V (typical), short-to-VCC is identified within 180–1200 µs after turn-off, and thermal shutdown activates at T_J ≥ 150°C with autorestart enabled only after junction cools below 135°C. The CS_DIS pin allows synchronous disabling of both current sense paths using a single CMOS-high signal.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Channels	Dual independent high-side switches with separate IN/OUT/CS pins per channel
On-State Resistance	25 mΩ typ. at 3 A, 25°C - enables <100 mV drop at 4 A, minimizing conduction loss in 12 V systems
Current Limitation	47 A typ. at 13 V - sustains brief inrush into capacitive/inductive loads without latch-off
Operating Voltage	4.5 V to 28 V - supports cold-crank (4.5 V) and load-dump (28 V) conditions in automotive 12 V networks
Current Sense Ratio	K₀ = 1000–5000 (I_OUT/I_SENSE) - provides scalable analog feedback for MCU ADC with ±9% drift over temperature
Thermal Shutdown	150°C activation with 135°C reset - ensures safe cycling under sustained overload without permanent disable
Input Compatibility	3 V/5 V CMOS logic - interfaces directly with automotive microcontrollers without level-shifting

Pinout & Package

Package: PowerSSO-36 - thermally enhanced exposed-pad SO package with 36 leads, optimized for PCB heat dissipation in automotive under-hood environments.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4.5–28 V DC; clamped to 41 V transient; powers internal logic and gate drivers
GND	Power and signal reference	Common return path for load current, sense circuitry, and logic; must be low-impedance
IN1, IN2	CMOS-compatible enable inputs	3 V/5 V logic-controlled; hysteresis prevents noise-induced switching; drives internal power MOSFET gates
OUT1, OUT2	High-side output terminals	Switched 12 V outputs to grounded loads; each rated for 47 A peak with built-in overcurrent limiting
CS1, CS2	Analog current sense outputs	Deliver I_SENSE = I_OUT/K; require external 10 kΩ pull-up to VCC for voltage-mode readout
CS_DIS	Active-high current sense disable	Pulling high disables both CS1/CS2 outputs - enables shared external sense resistor across multiple devices

Key Features

Feature	Design Value
Proportional analog current sense	Per-channel I_SENSE with K-ratio guaranteed from -40°C to 150°C, enabling precise real-time load monitoring
OFF-state open-load detection	Identifies disconnected loads at V_OUT > 2 V without requiring external components or MCU polling
Self-limiting fast thermal transients	Power limitation reduces I_OUT during overload to hold T_J < 150°C - avoids thermal shutdown during brief surges
Reverse battery protection	Internal MOSFET auto-enables at -13 V reverse polarity, blocking reverse current while maintaining functionality
Short-to-VCC diagnosis	Detects output shorted to battery via voltage decay analysis during turn-off - reported through CS pin behavior

Applications

Headlamp Switching

Fog Lamp Control

Use Scenario: PWM-controlled high-beam and low-beam switching in modern LED headlamp modules.

IC Role / Device Role / Timing Role: High-side driver providing regulated 12 V supply to LED arrays with real-time current feedback for brightness stabilization.

Use Value: 25 mΩ R_ON minimizes thermal rise during continuous operation; analog current sense enables closed-loop dimming without external shunt resistors.

Use Scenario: Independent on/off control of front/rear fog lamps with diagnostic reporting for ECU integration.

IC Role / Device Role / Timing Role: Dual-channel load switch with per-channel fault signaling - detects open-circuit bulbs or shorted wiring before fuse blow.

Use Value: OFF-state open-load detection (2–4 V threshold) identifies burnt-out lamps instantly; CS_DIS allows shared sense resistor across multiple lamps.

Engine Cooling Fan Drive

Power Window Motor Interface

Use Scenario: Variable-speed control of brushless cooling fans using PWM + current feedback for stall detection.

IC Role / Device Role / Timing Role: High-current high-side driver with fast (<300 µs) current sense response to capture inrush and stall events.

Use Value: 47 A current limit handles fan startup surge; thermal shutdown with autorestart prevents lockup during blade obstruction.

Use Scenario: Bidirectional motor control via H-bridge configuration using two VND5E025AY-E devices per window channel.

IC Role / Device Role / Timing Role: High-side half-bridge element enabling controlled 12 V application to motor terminals with overload protection.

Use Value: Short-to-VCC detection (180–1200 µs delay) identifies wiring faults before motor damage; reverse battery protection safeguards against jump-start errors.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VND5E050AK-E	50 mΩ R_ON, 60 A current limit, same PowerSSO-36 package and pinout	Higher R_ON increases conduction loss but improves thermal margin for sustained loads	Select when lower cost or higher current safety margin outweighs efficiency needs
TPS4H160-Q1	Single-channel, 160 mΩ R_ON, SPI interface instead of analog current sense	Lacks per-channel analog sense; requires MCU firmware for diagnostics instead of hardware-level feedback	Prefer when digital bus control and configurability are prioritized over analog simplicity

Compared with VND5E025AY-E, VND5E050AK-E trades 25 mΩ conduction loss for higher current capability and thermal robustness, while TPS4H160-Q1 replaces analog sense with programmable digital diagnostics - making the VND5E025AY-E optimal for cost-sensitive, analog-feedback automotive systems requiring dual-channel integration and minimal MCU overhead.

FAQ

What is the maximum transient voltage the VND5E025AY-E can withstand on VCC?

The device supports up to 41 V DC transient supply voltage on VCC, compliant with ISO 7637-2 Pulse 1 and Pulse 4 requirements for automotive 12 V systems. This rating includes active overvoltage clamp protection that limits internal node stress during load dump events without external TVS diodes.

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

When CS_DIS is pulled high, both CS1 and CS2 outputs are disabled - halting analog current feedback and suppressing all current-related diagnostics (overload, short-to-ground, open-load). This allows sharing of a single external sense resistor across multiple VND5E025AY-E devices in multi-channel systems, reducing BOM count and PCB area.

Can the VND5E025AY-E drive inductive loads like solenoids without external flyback protection?

Yes - the device integrates active demagnetization energy handling with V_DEMAG clamping down to V_CC − 52 V, enabling direct drive of solenoids and relays up to 6 mH inductance without external freewheeling diodes. Maximum safe demagnetization energy is 29 mJ per pulse at 13.5 V V_CC.

What is the thermal resistance from junction to case (R_thj-case) for one channel operating?

R_thj-case is 1.4 °C/W with one channel active, measured under standard JEDEC test conditions on a 4-layer PCB with 200 mm² copper pad beneath the exposed die paddle. This value assumes proper soldering of the PowerSSO-36 thermal pad and enables accurate junction temperature estimation for thermal design validation.
