Product details

Overview

VND5E008AYTR-E from STMicroelectronics is a double-channel high-side driver with integrated analog current sense, designed for automotive resistive/inductive/capacitive load control. It features 8 mΩ typical on-state resistance per channel, 76 A typical current limitation, ±40 °C to +150 °C junction operating range, and diagnostic reporting via proportional current sense output-used in body control modules for headlight or fan actuation.

For engineers reviewing the VND5E008AYTR-E datasheet, VND5E008AYTR-E pinout, VND5E008AYTR-E application, or VND5E008AYTR-E equivalent, key selection criteria include its AEC-Q100 qualified PowerSSO-36 package, dual-channel independent control with CMOS-compatible inputs, real-time analog current sensing (K₀ = 6000 typ), and fault reporting for open-load, short-to-VCC, overload, and thermal shutdown.

Technical Context

The device implements two independent VIPower® MOSFET high-side switches with active power limitation during inrush and overload, enabling safe driving of inductive loads without external snubbers. Its analog current sense delivers I_SENSE = I_OUT/K₀ (K₀ = 6000 typ) with <±12% drift over temperature and load range, and supports diagnostic enable/disable via CS_DIS.

Protection architecture includes undervoltage shutdown (V_USD = 4.5 V typ), overvoltage clamp (41 V transient), reverse battery protection, self-limiting thermal transients, and automatic thermal shutdown with restart at 135 °C reset threshold-ensuring robust operation in 12 V/24 V automotive electrical systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating Voltage Range	4.5 V to 28 V DC - supports full automotive battery range including cold-crank (4.5 V) and load-dump (28 V continuous)
On-State Resistance (per ch.)	8 mΩ typ @ 25 °C - enables low conduction loss (<60 mW @ 2.5 A) and minimal thermal rise in compact PCB layouts
Current Limitation	76 A typ - sustains short-circuit conditions without external fusing while limiting peak power dissipation
Junction Temperature Range	−40 °C to +150 °C - meets AEC-Q100 Grade 0 requirements for under-hood applications
Current Sense Ratio	K₀ = 6000 typ (I_OUT/I_SENSE) - provides precise analog feedback for closed-loop current monitoring and diagnostics
Diagnostic Reporting	Single-pin analog current sense output encodes open-load, short-to-VCC, overload, and thermal faults - eliminates need for separate fault lines
Input Logic Compatibility	3.0 V CMOS-compatible with 0.9 V/2.1 V thresholds and 0.25 V hysteresis - interfaces directly with automotive microcontrollers without level-shifting

Pinout & Package

Delivered in PowerSSO-36 exposed-pad surface-mount package with integrated thermal pad for enhanced heat dissipation in automotive under-hood environments. Pin count: 36 terminals; mounting: solder-reflow compatible; RoHS-compliant ECOPACK®.

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 power stage
GND	Power and signal reference	Common return for load current, logic, and sense circuitry; connected to thermal pad
IN1, IN2	CMOS-compatible control inputs	Directly drive each channel; 0.9 V/2.1 V thresholds with hysteresis prevent noise-induced switching
OUT1, OUT2	High-side power outputs	Switched battery voltage to loads; support inductive demagnetization energy up to 260 mJ
CS1, CS2	Analog current sense outputs	Deliver I_SENSE = I_OUT/K₀; used for real-time load monitoring and fault detection
CS_DIS	Current sense enable/disable control	Active-high CMOS input; disables sense output and reduces leakage to ≤2 µA when high

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents voltage droop and EMI during cold-start lamp or motor turn-on
Proportional analog current sense	±12% max ratio drift over −40 °C to +150 °C enables accurate load current reconstruction without calibration
Off-state open-load detection	Detects disconnected loads at VIN = 0 V using VOL threshold (2–4 V) - critical for lamp-out diagnostics
Thermal shutdown with auto-restart	Shuts down at 150–200 °C and recovers at 135 °C - maintains system availability after transient overloads
Reverse battery protection	Self-switching MOSFET blocks −16 V reverse supply without external diode - reduces BOM count and footprint

Applications

Headlight Control Module

Fan Actuation System

Use Scenario: Driving halogen or LED headlights with PWM dimming and open-circuit fault detection.

IC Role / Device Role / Timing Role: High-side switch providing battery-referenced load control with real-time current feedback for brightness regulation and burn-out reporting.

Use Value: Eliminates need for discrete current-sense resistors and comparators; K₀ = 6000 analog output enables direct ADC sampling by MCU for closed-loop luminance control.

Use Scenario: Controlling radiator cooling fans in engine bay with thermal overload protection.

IC Role / Device Role / Timing Role: Dual-channel driver managing main and auxiliary fans independently, with integrated demagnetization energy handling (260 mJ).

Use Value: Withstands inductive kickback without external TVS; thermal shutdown + auto-restart ensures fan continues operation after temporary overheating.

Seat Motor Control Unit

Window Lift Module

Use Scenario: Bidirectional seat position adjustment using H-bridge configuration with high-side drivers.

IC Role / Device Role / Timing Role: One channel drives motor forward, the other reverse; CS_DIS synchronizes sense disable during direction reversal to avoid false fault signals.

Use Value: On-resistance of 8 mΩ minimizes voltage drop across driver, preserving motor torque at low battery voltages (e.g., 9 V cold crank).

Use Scenario: Anti-pinch window lift control requiring precise current monitoring for obstacle detection.

IC Role / Device Role / Timing Role: High-side driver with analog current sense feeding MCU ADC to detect abnormal current rise during glass obstruction.

Use Value: Current sense delay <300 µs (Δt_DSENSE2H) enables sub-10 ms response to pinch events - meeting ISO 11452-2 EMC and functional safety timing constraints.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Single-channel, 160 mΩ R_ON, no integrated current sense - requires external sensing	Suitable for lower-current (≤2 A), cost-sensitive modules where diagnostics are handled externally	Select when board space allows discrete sensing and thermal design accommodates higher R_ON losses
VND7140AJTR-E	Double-channel, 140 mΩ R_ON, digital current sense (1:2000 ratio), lower ILIM (14 A)	Targeted at interior lighting and low-power actuators; lacks analog precision for motor stall detection	Prefer for non-motor applications where digital fault flags suffice and lower current capability is acceptable

Compared with TPS4H160-Q1 and VND7140AJTR-E, VND5E008AYTR-E uniquely combines dual-channel 8 mΩ conduction, analog current sense with <±12% drift, and 76 A overload tolerance - making it optimal for high-power, safety-critical automotive actuators requiring both precision monitoring and robust fault resilience.

FAQ

What is the maximum transient voltage the VND5E008AYTR-E can withstand?

The device supports up to 41 V transient supply voltage (V_CCPK) for durations under 400 ms with R_LOAD > 1 Ω, per absolute maximum ratings. This rating covers standard automotive load-dump events defined in ISO 7637-2 Pulse 5a, and is enforced by an internal active clamp circuit that limits voltage without external components.

How does the current sense function behave during thermal shutdown?

During thermal shutdown, the current sense output (CS1/CS2) transitions to a high-impedance state and delivers I_SENSEH = 9 mA into a 5 V load, signaling overtemperature condition. This fault current remains active until junction temperature drops below the 135 °C reset threshold, enabling unambiguous software detection of thermal events.

Can unused IN pins be left floating?

No. Unused IN1 or IN2 pins must be tied to GND through a 10 kΩ resistor per Table 2 of the datasheet. Floating inputs risk unintended channel activation due to noise coupling, especially in high-EMI automotive environments; grounding ensures predictable OFF-state behavior and avoids latch-up risks.

Is reverse battery protection active during all operating modes?

Yes. Reverse battery protection operates continuously when V_CC is between −16 V and 0 V, regardless of IN pin state or load condition. The integrated self-switching MOSFET blocks reverse current flow without external components, maintaining zero quiescent current draw and preventing damage to downstream circuitry.
