Product details

Overview

VND5E008ASP-E from STMicroelectronics is a dual-channel automotive high-side driver IC with integrated analog current sense, designed for 12 V grounded loads in engine control units, body electronics, and lighting systems. It features 7.7 mΩ typical on-state resistance per channel, 85 A current limitation, 4.5–28 V operating supply range, and real-time diagnostic feedback via dedicated CS1/CS2 pins.

For engineers reviewing the VND5E008ASP-E datasheet, VND5E008ASP-E pinout, VND5E008ASP-E application, or VND5E008ASP-E equivalent, this page delivers verified electrical specs, automotive-grade protection behavior, thermal shutdown auto-restart timing, and precise current-sense ratio drift (±7% max at 18 A), critical for functional safety validation and ASIL-B system design.

Technical Context

The device implements two independent VIPower® M0-5 high-side switches with active power limitation during overload/short-to-ground events, enabling self-regulated current clamping without external intervention. Each channel integrates CMOS-compatible 3.0 V logic inputs with 0.25 V hysteresis and reverse-battery protection via internal self-switching PowerMOS.

Diagnostic architecture includes proportional analog current sensing (K₀ = 3550–9350 A/A) across 0.5–18 A load range, off-state open-load detection (2–4 V threshold), short-to-VCC delay (180–1200 µs), and thermal shutdown indication with 7 °C hysteresis (TTSD = 150–200 °C, TR = TRS + 1 to +5 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
Operating voltage	4.5–28 V DC - supports full automotive battery range including cold-crank (4.5 V) and load-dump transients (41 V peak)
On-state resistance	7.7 mΩ typ @ 6 A, 25 °C - enables <100 mW conduction loss per channel at 10 A, reducing thermal stress
Current limit	85 A typ DC short-circuit - provides robust fault containment while maintaining SOA during sustained overloads
Current sense accuracy	±13% ratio drift @ 6 A, ±7% @ 18 A - ensures reliable fault classification (open-load vs. short) across full temperature range (−40 to +150 °C)
Thermal shutdown	150–200 °C trip, auto-restart after 7 °C hysteresis - prevents permanent damage during intermittent faults without MCU intervention
Undervoltage lockout	4.5 V threshold with 0.5 V hysteresis - blocks erroneous turn-on during battery recovery or brown-out conditions
ESD rating	4 kV HBM on inputs, 5 kV on VCC/output - exceeds ISO 10605 requirements for automotive module integration

Pinout & Package

Supplied in PowerSO-16 package: thermally enhanced exposed die-pad, RoHS-compliant, ECOPACK® certified, with 0.5 °C/W junction-to-case thermal resistance (one channel ON).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4.5–28 V DC; withstands 41 V transient (400 ms); clamped to 41–52 V during overvoltage events
GND	Power ground reference	Common return for load current, sense circuitry, and logic; tied to exposed thermal pad for heat dissipation
IN1, IN2	CMOS-compatible enable inputs	3.0 V logic threshold (VIH = 2.1 V, VIL = 0.9 V); 0.25 V hysteresis prevents noise-induced switching
OUT1, OUT2	High-side power outputs	Drive grounded resistive/inductive/capacitive loads; support reverse-battery protection and demagnetization energy handling
CS1, CS2	Analog current sense outputs	Deliver proportional current (ISENSE = IOUT/K) for real-time diagnostics; max 5 V output, leakage ≤2 µA
CS_DIS	Current sense disable control	Active-high CMOS input; disables CS1/CS2 to share external sense resistor across multiple devices
AGND	Analog ground reference	Separate low-noise ground for current sense circuitry; improves measurement accuracy under EMI

Key Features

Feature	Design Value
Proportional analog current sense	Three-point calibrated gain (K₀/K₁/K₂/K₃) with ≤±15% drift over −40 to +150 °C - enables precise fault grading (mild overload vs. hard short)
Off-state open-load detection	2–4 V threshold at VOUT; validated with external pull-up - detects broken-wire faults before actuation, supporting ISO 26262 diagnostic coverage
Power limitation during overload	Self-regulating current clamp at 85 A typ, with thermal cycling (I_limL = 21 A) - avoids destructive latch-up while preserving device integrity
Inrush current management	Active power limitation during capacitive load turn-on - eliminates need for external NTC or soft-start circuitry
Loss-of-ground/loss-of-VCC protection	Dedicated monitoring circuits trigger diagnostic flags - ensures fail-safe behavior when vehicle harness faults occur

Applications

Engine Control Unit (ECU)

Automotive Lighting System

Use Scenario: Driving solenoid valves and fuel injectors in gasoline/diesel ECUs under harsh thermal and EMI conditions.

IC Role / Device Role / Timing Role: High-side switch with real-time current feedback for closed-loop injector pulse-width validation and stall detection.

Use Value: 7.7 mΩ R_ON minimizes voltage drop during cranking (4.5 V), ensuring reliable valve actuation; thermal auto-restart maintains limp-home operation after overheating.

Use Scenario: Controlling LED headlamps and matrix lighting modules requiring PWM dimming and open-circuit fault reporting.

Use Value: ±7% current sense drift at 18 A enables accurate luminance matching across channels; off-state open-load detection (2–4 V) identifies single-LED failures without additional sensors.

Body Control Module (BCM)

Heating/Ventilation Actuator

Use Scenario: Managing window lift motors, seat adjusters, and mirror actuators with bidirectional stall detection and ESD-hardened interface.

IC Role / Device Role / Timing Role: Robust high-side driver with short-to-VCC diagnosis (180–1200 µs delay) and reverse-battery protection for 12 V chassis integration.

Use Value: 41 V transient tolerance and 4 kV HBM ESD rating eliminate need for external TVS diodes; CS_DIS pin allows shared sense resistor across 4+ channels in compact BCM layouts.

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 analog current sense - uses digital SPI diagnostics only	Lacks proportional analog feedback; requires external ADC for current monitoring	Preferred for space-constrained designs where digital bus integration outweighs analog diagnostic fidelity
VND7050AJTR-E	Double-channel, 50 mΩ R_ON, 12 A current limit, 1.5× lower sense accuracy (±20% drift)	Lower power capability; suitable for auxiliary loads but not primary engine actuators	Cost-optimized alternative for non-safety-critical BCM functions where 85 A clamping is unnecessary

Compared with TPS4H160-Q1 and VND7050AJTR-E, the VND5E008ASP-E uniquely combines dual-channel 85 A clamping, ±7% current sense precision at full load, and automotive-qualified thermal auto-restart - making it the only option meeting ASIL-B diagnostic coverage requirements for critical power distribution nodes.

FAQ

What is the maximum allowable transient voltage on VCC?

The VND5E008ASP-E supports up to 41 V transient supply voltage for durations under 400 ms, as specified in Table 3 of the datasheet. This rating covers ISO 7637-2 Pulse 5a load-dump events without external clamping, provided R_LOAD > 0.5 Ω. Sustained operation above 28 V DC is prohibited.

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

Pulling CS_DIS high places CS1 and CS2 into high-impedance state, disabling analog current feedback from both channels. This allows sharing of a single external sense resistor across multiple VND5E008ASP-E devices in multi-output systems, reducing BOM count and PCB area - but eliminates per-channel fault discrimination during disabled periods.

Can the device drive inductive loads without external flyback diodes?

Yes - the VND5E008ASP-E integrates active voltage clamping that limits V_OUT to V_CC − 28 V during demagnetization (Table 8). Tested up to 280 mJ single-pulse energy at 16 V V_CC, it safely handles typical automotive solenoids and relays without external diodes, though layout must minimize parasitic inductance.

What is the thermal reset behavior after overtemperature shutdown?

Upon reaching 150–200 °C junction temperature, the device shuts down and automatically restarts once junction temperature falls to TR = TRS + 1 to +5 °C (TRS = 135 °C). This hysteresis prevents oscillation near trip point and ensures stable recovery without MCU polling - critical for unattended operation in engine compartments.
