Product details

Overview

VNQ810M from STMicroelectronics is a quad-channel high-side driver IC designed for automotive and industrial load switching, featuring 150 mΩ R_DS(on) per channel, 0.6 A continuous output current, 36 V supply voltage rating, CMOS-compatible inputs, and open-drain status outputs. It integrates two VND810M dies in a single SO-28 (double island) package to drive grounded loads such as lamps, solenoids, and relays in 12 V/24 V systems.

For engineers reviewing the VNQ810M datasheet, VNQ810M pinout, VNQ810M application, or VNQ810M equivalent, key selection criteria include on-state resistance stability over temperature, dual-island thermal isolation for parallel channel operation, integrated open-load detection in both ON/OFF states, and ISO 7637-2 transient immunity compliance for automotive environments.

Technical Context

The VNQ810M implements four independent high-side switches using ST's VIPower M0-3 technology, each with active current limiting (1.4 A typ.), thermal shutdown (150 °C trip), undervoltage (4 V) and overvoltage (36 V) protection, and loss-of-ground detection. Its dual-island SO-28 layout isolates channels into two thermally independent groups (pins 1–14 and 15–28), enabling concurrent operation without thermal crosstalk.

Each channel provides diagnostic feedback via open-drain status pins that indicate overload, open load (ON/OFF state), overtemperature, and supply faults. The device supports reverse-battery protection via external GND-line network design and features active V_CC clamping to absorb low-energy transients per ISO 7637-2 Pulse 1, 2a, 3a/b, and 5a.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	150 mΩ per channel at I_OUT = 0.5 A, T_j = 25 °C - ensures ≤75 mW conduction loss at rated current, minimizing thermal rise in compact layouts.
I_OUT (continuous)	0.6 A per channel - matches standard 21 W/12 V bulb load, enabling direct replacement of electromechanical relays without external current sensing.
V_CC range	5.5 V to 36 V - supports wide automotive battery range including cold-crank (5.5 V) and load-dump (36 V) conditions without external regulation.
Open-load detection	Detects open circuit in both ON state (20–80 mA threshold) and OFF state (1.5–3.5 V threshold) - enables fail-safe diagnostics without added external components.
Thermal shutdown	150 °C trip with 135 °C reset hysteresis - prevents latch-up during sustained overload and allows automatic recovery after fault clearance.
ISO 7637-2 immunity	Class C performance across all pulses (1, 2a, 3a/b, 4, 5a) - eliminates need for external TVS or RC snubbers in OEM-compliant ECU designs.

Pinout & Package

Package: SO-28 (double island), surface-mount, thermally enhanced with two isolated copper islands for independent thermal management of channel pairs.

Pin/Terminal	Circuit Role	Design Meaning
VCC1,2	Power supply input (Island 1)	Supplies channels 1 and 2; must be decoupled locally; connects to battery rail with transient suppression.
GND1,2	Ground reference (Island 1)	Return path for channels 1 and 2; requires low-inductance connection to chassis ground to support loss-of-ground detection.
INPUT1–4	Digital control inputs	CMOS-compatible (V_IL = 1.25 V, V_IH = 3.25 V); tolerate ±1 mA clamp current up to 8 V.
OUTPUT1–4	High-side switched outputs	Drive grounded loads; feature internal V_CC-to-output diode (V_F = 0.6 V) for demagnetization energy clamping.
STATUS1–4	Open-drain diagnostic outputs	Pull-low on fault (overload, open load, overtemp); require external pull-up for logic-level reporting to MCU.
VCC3,4 / GND3,4	Power & ground (Island 2)	Independent supply/ground for channels 3 and 4; enables dual-zone thermal monitoring and fault isolation.

Key Features

Feature	Design Value
Quad-channel integration in SO-28	Reduces PCB area by >40% vs. discrete dual-channel solutions while maintaining thermal independence between channel pairs.
On/off-state open-load detection	Eliminates need for external sense resistors or ADC monitoring-reduces BOM count and improves system reliability in lamp-control applications.
Reverse battery protection support	Enables robust GND-line protection networks (resistor or diode-based) per Figure 24, preventing damage during battery misconnection.
Active current limitation + thermal restart	Current limit (0.9 A typ.) combined with auto-restart prevents destructive latch-up during short-circuit events in solenoid or motor startup.
Loss-of-ground detection	Automatically disables all outputs if GND pins disconnect-critical safety feature for automotive body control modules (BCMs).

Applications

Use Scenario: Controlling pneumatic/hydraulic solenoid valves in factory automation PLC I/O modules.

IC Role / Device Role / Timing Role: Robust load switch with fast turn-on/turn-off delay (<30 µs) and demagnetization energy handling (V_demag = V_CC − 41 V).

Use Value: Eliminates need for external flyback diodes and current-sense amplifiers, simplifying valve-driver design while supporting 100 k-cycle lifetime requirements.

Truck & Bus Power Distribution

Off-Highway Equipment Monitoring

Use Scenario: Centralized power distribution units (PDUs) managing auxiliary loads (heaters, wipers, horns) in 24 V commercial vehicles.

IC Role / Device Role / Timing Role: Fault-tolerant high-side driver with ISO 7637-2 Class C immunity and dual-island thermal separation for multi-load redundancy.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN810M	Single-channel version in SO-8; identical electrical specs per channel but no dual-island thermal partitioning.	Limited to one load per package; requires four devices for quad functionality, increasing PCB area and thermal coupling risk.	Select when board space permits discrete layout and thermal management is centralized.
Infineon BTS716G	Quad-channel HSD in PG-DSO-28; lower R_DS(on) (100 mΩ), higher I_OUT (1.2 A), but lacks OFF-state open-load detection and reverse-battery support circuitry.	Better suited for high-current resistive loads; not recommended for lamp-load diagnostics requiring OFF-state verification.	Select when peak current >0.8 A is required and diagnostic depth is secondary to conduction efficiency.

Compared with STVN810M, VNQ810M saves 75% board area and enables true channel-level thermal independence; compared with BTS716G, it delivers superior diagnostic coverage for safety-critical lamp and valve monitoring but trades off 50 mΩ R_DS(on) for integrated protection architecture.

FAQ

What is the maximum junction temperature and thermal shutdown behavior?

The VNQ810M triggers thermal shutdown at 150 °C (typ.) with a 135 °C reset hysteresis. During overload, current limiting activates first (0.9 A typ. at 13 V), followed by thermal shutdown if dissipation exceeds R_thj-amb limits. Automatic restart occurs only after junction cools below reset threshold and input remains asserted.

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

OFF-state open-load detection monitors output voltage decay through an internal current source; if V_OUT rises above 2.5 V (typ.) while INPUT = LOW, STATUS pulls low. No external components are required-only a pull-up resistor on STATUS (typically 10 kΩ to V_CC) for MCU interfacing.

Can VNQ810M drive inductive loads like fuel injectors without external flyback protection?

Yes-the integrated V_CC-to-output clamp diode (V_F = 0.6 V) handles demagnetization energy up to 174 mJ (L = 2.5 mH, I_L = 9 A). For injectors exceeding this energy, external TVS or Zener clamping is required per Figure 26 guidelines.

Is VNQ810M still in active production or marked obsolete?

Per STMicroelectronics' official documentation (DocID7388 Rev 4, Sept 2013), VNQ810M is marked "Obsolete Product(s)" in the document header. However, Aetrix Electronics maintains legacy inventory and offers lifecycle management services-including last-time buy coordination and cross-reference support-for ongoing production continuity.
