Product details

Overview

VNQ810-E from STMicroelectronics is a quad-channel high-side driver IC built using VIPower M0-3 technology, integrating two VND810-E dies in a single SO-28 double-island package. It drives grounded loads with 160 mΩ R_DS(on), 3.5 A continuous per channel, and operates from 5.5 V to 36 V supply. Designed for automotive body control modules, it provides open-load detection (on/off state), short-circuit protection, thermal shutdown, reverse-battery protection, and ISO 7637-2 transient immunity.

For engineers reviewing the VNQ810-E datasheet, VNQ810-E pinout, VNQ810-E application, or VNQ810-E equivalent, key selection criteria include per-channel current limiting (5.5–7.5 A), status output diagnostics, dual-island thermal isolation, undervoltage/overvoltage lockout thresholds (4 V / 36 V), and SO-28 mechanical compatibility with legacy high-side driver footprints.

Technical Context

The VNQ810-E implements four independent high-side switches with CMOS-compatible inputs and open-drain status outputs. Each channel features active current limiting, thermal foldback with 150 °C trip and 135 °C reset, and integrated clamping for demagnetization energy (V_DEMAG = V_CC − 41 V typical).

Its dual-island SO-28 layout isolates two pairs of channels thermally and electrically-enabling independent operation and fault containment. Protection logic includes loss-of-ground detection, off-state open-load sensing via external pull-up, and input clamp diodes rated to ±8 V.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	160 mΩ max at I_OUT = 1 A, T_j = 25 °C - ensures low conduction loss and <1.2 W dissipation at 3.5 A
I_OUT Continuous	3.5 A per channel - supports automotive solenoids, relays, and lamps without external heatsinking on standard FR-4
V_CC Range	5.5 V to 36 V - covers full automotive battery range including cold-crank (5.5 V) and load-dump (36 V)
Open-Load Detection	On-state: 20–80 mA threshold; Off-state: VOL > 1.5 V - enables robust fault reporting without additional sensors
Thermal Shutdown	150 °C trip, 135 °C reset with 15 °C hysteresis - prevents latch-up during sustained overload
ISO 7637-2 Immunity	Pulse 1–5 compliant up to Level IV - withstands real-world automotive transients without external TVS
Status Output	Open-drain, 1.6 mA sink capability, 0.5 V max low-level voltage - directly interfaces with 3.3 V/5 V microcontrollers

Pinout & Package

Package: SO-28 (Double Island), 300 mil width, 1.27 mm pitch, dual isolated thermal islands - enables independent thermal management for two channel pairs.

Pin/Terminal	Circuit Role	Design Meaning
VCC1,2	Power supply for island 1 (channels 1 & 2)	Must be decoupled locally; shared VCC pins reduce PCB routing complexity
VCC3,4	Power supply for island 2 (channels 3 & 4)	Electrically and thermally isolated from VCC1,2 - allows independent supply domains
GND1,2 / GND3,4	Ground return for respective islands	Separate ground pins prevent cross-talk and improve fault isolation
INPUT1–4	CMOS-compatible digital enable inputs	VIH = 3.25 V min, VIL = 1.25 V max - compatible with standard MCU GPIOs
OUTPUT1–4	High-side switched outputs	Drive grounded loads; support inductive kickback clamping up to 23 mJ
STATUS1–4	Open-drain diagnostic outputs	Report overtemperature, open-load, short-to-VCC, and undervoltage conditions per channel

Key Features

Feature	Design Value
Per-channel open-load detection (on/off)	Eliminates need for external current sense resistors or auxiliary comparators in lamp/relay monitoring
Dual-island SO-28 thermal architecture	Reduces mutual heating between channel pairs - improves power density and reliability in multi-load systems
Reverse battery protection	Withstands −14 V applied to VCC (per absolute max rating) - protects against incorrect jump-start scenarios
Integrated VCC clamp	Clamps low-energy transients (e.g., ISO 7637 Pulse 1) without external components - reduces BOM count
Loss-of-ground detection	Automatically disables outputs if GND connection fails - prevents uncontrolled load activation

Applications

Body Control Module (BCM)

Engine Bay Power Distribution

Use Scenario: Controlling headlights, fog lamps, and interior lighting in modern vehicle BCMs.

IC Role / Device Role / Timing Role: High-side switch providing PWM-capable load control with real-time status feedback to MCU.

Use Value: Enables centralized diagnostics (open-load, short-circuit) across 4 independent lighting circuits without added sensing circuitry.

Use Scenario: Driving radiator fans, fuel pumps, and HVAC actuators in engine compartment junction boxes.

IC Role / Device Role / Timing Role: Robust high-current switching with thermal foldback and transient immunity for harsh under-hood environments.

Use Value: Sustains 3.5 A continuous per channel at 125 °C ambient - eliminates need for discrete MOSFET + driver + protection IC combos.

Seat & Mirror Control Unit

Commercial Vehicle Trailer Interface

Use Scenario: Managing seat heater elements, power mirror motors, and memory position actuators.

IC Role / Device Role / Timing Role: Precision current-limited drive with programmable status reporting for functional safety compliance.

Use Value: On-state open-load detection (20–80 mA threshold) verifies heater continuity before enabling full power - prevents false thermal faults.

Use Scenario: Interfacing tractor ECUs with trailer lighting, ABS valves, and air suspension solenoids.

IC Role / Device Role / Timing Role: High-side driver tolerant of wide supply variation (5.5–36 V) and long cable-induced transients.

Use Value: ISO 7637-2 Pulse 5 (load dump) immunity up to +86.5 V peak - avoids external TVS diodes on VCC line.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VNQ830-E	Higher R_DS(on) (250 mΩ), same SO-28 double-island, 3.5 A rating, adds SPI interface	Requires MCU with SPI support; offers enhanced diagnostics but higher conduction loss	Choose when advanced register-based fault logging is required over analog status pins
TPS27082L	Single-channel, 3.6 A, 12 V max, QFN-16, no open-load detection in off-state	Lacks dual-island thermal separation and off-state open-load sensing - not drop-in replaceable	Select only for new designs where space constraints outweigh need for comprehensive diagnostics

Compared with VNQ810-E, VNQ830-E trades higher on-resistance for digital configurability, while TPS27082L sacrifices channel count, thermal isolation, and diagnostic depth for compactness - making VNQ810-E optimal for cost-sensitive, high-diagnostic automotive modules requiring four independent protected outputs.

FAQ

What is the maximum safe operating voltage for VNQ810-E?

The absolute maximum DC supply voltage is 41 V, but the recommended operating range is 5.5 V to 36 V. Operation above 36 V triggers overvoltage shutdown (VOV = 36 V nominal), protecting internal circuitry. Transient spikes up to +86.5 V (ISO 7637 Pulse 5) are tolerated due to integrated VCC clamping - no external TVS required for compliance.

How does off-state open-load detection work, and what external components are needed?

Off-state open-load detection requires an external pull-up resistor (RPU) between OUTPUTn and a positive supply (e.g., +5 V). When the load is disconnected, OUTPUTn rises above 1.5 V (VOL threshold), triggering STATUSn low. RPU must satisfy two conditions: (1) keep VOUT < 1.5 V when load is connected, and (2) ensure VOUT > 3.5 V when open - typically 10–47 kΩ depending on load resistance and supply voltage.

Can VNQ810-E drive inductive loads like solenoids or relays without external flyback diodes?

Yes - VNQ810-E integrates active demagnetization clamping with V_DEMAG = V_CC − 41 V (typical), allowing safe energy dissipation for inductive loads up to 23 mJ (L = 1.38 mH, IL = 5 A). This eliminates need for external freewheeling diodes in most automotive solenoid and relay applications, reducing board area and component count.

Is VNQ810-E pin-compatible with earlier ST high-side drivers like VND810-E?

No - VNQ810-E is a quad-channel device in SO-28 double-island package, whereas VND810-E is a single-channel SO-8 device. However, VNQ810-E internally integrates two VND810-E dies, sharing identical per-channel electrical characteristics (R_DS(on), I_OUT, protection thresholds). Board redesign is required, but firmware logic and diagnostic interpretation remain consistent across both families.
