Product details

Overview

VNQ810TR-E from STMicroelectronics is a quad-channel high-side driver IC fabricated in VIPower M0-3 technology, designed for automotive and industrial load switching where one side of the load connects to ground. It delivers 3.5A per channel, features 160mΩ on-state resistance at 25°C, integrated open-load detection (both ON/OFF states), short-circuit protection, and ±41V absolute maximum VCC rating. It is used in body control modules for driving lamps, solenoids, and relays.

For engineers reviewing the VNQ810TR-E datasheet, VNQ810TR-E pinout, VNQ810TR-E application, or VNQ810TR-E equivalent, key selection criteria include per-channel current limit (3.5A), thermal shutdown threshold (150°C), status pin diagnostics (open-load/overtemp/UV/OV), reverse battery protection capability, and SO-28 double-island package thermal performance under pulsed inductive loads.

Technical Context

The VNQ810TR-E integrates two independent VND810-E dies in a single SO-28 double-island package, enabling four fully isolated high-side switch channels with shared VCC/GND islands. Each channel implements active current limiting, thermal shutdown with 15°C hysteresis, and voltage clamping (VCC clamp, status clamp, output demagnetization clamp) compliant with ISO 7637-2 Pulse 1, 2a, 3a/b, 4, and 5.

It supports CMOS-compatible inputs (VIH = 3.25V, VIL = 1.25V), provides open-drain status outputs with internal pull-down, and detects open loads in both ON state (20–80mA threshold) and OFF state (1.5–3.5V threshold with external pull-up). Protection logic includes loss-of-ground detection via dedicated IGND pins and reverse-battery tolerance down to −0.3V on VCC.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	5.5V to 36V operating supply - supports 12V/24V automotive systems with headroom for load dump transients.
R_DS(on)	160mΩ max at I_OUT = 1A, T_j = 25°C - enables low conduction loss and <1W dissipation at 3.5A continuous.
I_OUT Limit	3.5A typical current limit - protects against sustained overload while allowing inrush for inductive loads.
Open Load Detection	ON-state: 20–80mA threshold; OFF-state: 1.5–3.5V threshold with external pull-up - enables robust fault reporting without external sensing circuitry.
Thermal Shutdown	150°C trip, 135°C reset (15°C hysteresis) - prevents permanent damage during sustained overloads or poor heatsinking.
ISO 7637-2 Compliance	Pulse 1 (−100V), Pulse 2a (+100V), Pulse 3a/b (±150V), Pulse 4 (−7V), Pulse 5 (+86.5V) - meets automotive EMC requirements without external TVS.
Status Output	Open-drain, 0.5V max low-level at 1.6mA - compatible with 3.3V/5V microcontrollers and supports wired-OR diagnostics.

Pinout & Package

Package: SO-28 (Double Island), 300 mil width, 1.27 mm pitch, dual thermal islands (pins 1–14 and 15–28 form two electrically isolated groups sharing VCC/GND pairs).

Pin/Terminal	Circuit Role	Design Meaning
VCC1,2 / VCC3,4	Power supply input (dual island)	Two independent VCC rails - allows separate power domains or redundancy; each powers two channels.
GND1,2 / GND3,4	Ground return (dual island)	Dedicated ground paths per island - critical for accurate current sensing and loss-of-ground detection.
INPUT1–4	CMOS logic input	Active-high control; 1µA leakage, 0.5V hysteresis - immune to noise and compatible with MCU GPIOs.
OUTPUT1–4	High-side switched output	Drives load between OUTPUT and ground; supports inductive loads up to 1.38mH with 23mJ safe switching energy.
STATUS1–4	Diagnostic open-drain output	Reports channel faults (open load, overtemp, UV/OV); requires external pull-up for logic-high indication.
N.C.	No connect	Pins 1, 14, 15, 28 - must be left floating per datasheet; no internal connection or function.

Key Features

Feature	Design Value
Per-channel diagnostic status	Single-pin open-drain reporting of open-load (ON/OFF), overtemperature, undervoltage, overvoltage, and short-to-VCC - reduces BOM count and simplifies firmware polling.
Reverse battery protection	Withstands −0.3V on VCC and supports external ground-line resistor/diode networks - eliminates need for upstream series diode in 12V systems.
Dual thermal islands	SO-28 package with physically separated die islands - enables independent thermal management and fault isolation between channel pairs.
Integrated VCC clamp	Clamps low-energy transients (ISO 7637 Pulse 1/2a/3a/b) without external components - reduces PCB area and system cost.
Loss-of-ground detection	Monitors IGND pin current (−200mA max reverse) and shuts down channel if ground path fails - enhances functional safety in critical loads.

Applications

Use Scenario: Controlling solenoid valves and indicator LEDs in DIN-rail mounted programmable logic controllers.

IC Role / Device Role / Timing Role: Robust 24V DC output driver with built-in short-circuit recovery and thermal foldback.

Use Value: Enables hot-swap capability and automatic fault recovery without controller intervention; supports 3.5A peak for valve actuation pulses.

Truck Trailer Control Unit

Off-Highway Equipment Lighting

Use Scenario: Managing trailer brake lights, turn signals, and ABS modulator power in heavy-duty vehicle towing systems.

IC Role / Device Role / Timing Role: Quad-channel HSD handling multiple 12V/24V loads with simultaneous status reporting and reverse-battery resilience.

Use Value: Meets SAE J1455 vibration/thermal specs; withstands −40°C to +125°C ambient with no derating up to 2.5A/channel.

Use Scenario: Powering LED work lights and beacon arrays on construction, mining, and agricultural machinery.

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
VNQ830TR-E	Higher R_DS(on) (300mΩ), lower I_OUT limit (2.1A), same SO-28 package and feature set	Better suited for lower-power loads (e.g., small relays, indicators) where thermal margin is constrained	Select when load current ≤2A and board space prohibits adding heatsink; retains identical pinout and diagnostics.
TPS4H160-Q1	Single-channel, 160mΩ, AEC-Q100 qualified, SPI interface instead of parallel inputs/status	Requires MCU firmware integration for configuration and fault readback; no native open-load OFF-state detection	Choose for systems needing channel configurability (current limit, slew rate) and CAN-based diagnostics; not drop-in replaceable.

Compared with VNQ810TR-E, VNQ830TR-E trades current capacity for lower thermal stress in compact layouts, while TPS4H160-Q1 shifts diagnostic granularity and control flexibility to software at the cost of increased MCU overhead and loss of hardware-level OFF-state open-load detection.

FAQ

What is the maximum continuous current per channel for VNQ810TR-E?

The VNQ810TR-E supports 3.5A continuous output current per channel at T_j ≤ 150°C with adequate PCB copper heatsinking (≥6 cm² per island). Derating applies above 100°C junction temperature; at 125°C, rated current drops to ~2.8A per channel based on thermal resistance data (R_thj-amb = 31°C/W for two channels ON).

Does VNQ810TR-E require external components for ISO 7637-2 Pulse 5 compliance?

No external components are required for ISO 7637-2 Pulse 5 (+86.5V, 400ms) compliance - the integrated VCC clamp and internal protection architecture handle this transient. However, a voltage transient suppressor (D_ld) is recommended if load-dump peaks exceed 41V or if system-level testing reveals marginal margin under combined transients.

How does open-load detection work in the OFF state?

OFF-state open-load detection requires an external pull-up resistor (R_PU) from OUTPUT to V_PU (e.g., +5V). When the load is disconnected, OUTPUT floats high (>1.5V), triggering STATUS low. When connected, OUTPUT is pulled low through the load, keeping STATUS high. Thresholds are 1.5–3.5V (V_OL) and detection delay is 1000µs.

Can VNQ810TR-E drive inductive loads like fuel injectors or solenoids?

Yes - it is qualified for inductive loads up to 1.38mH with 5A peak current and 23mJ demagnetization energy (T_jstart = 150°C). The integrated output clamp (V_DEMAG = V_CC−41V to V_CC−55V) safely dissipates flyback energy without external diodes, provided PCB layout minimizes parasitic inductance in the VCC/GND loop.
