Product details

Overview

VNQ810M-E from STMicroelectronics is a quad-channel high-side driver IC built using VIPower M0-3 technology, designed for automotive and industrial load switching where one side of the load connects to ground. It integrates two VND810M-E dies in a single SO-28 double-island package, delivers 0.6A per channel, features 150mΩ R_DS(on), supports 36V V_CC, and provides on/off-state open-load detection - used in body control modules for lamp and solenoid driving.

For engineers reviewing the VNQ810M-E datasheet, VNQ810M-E pinout, VNQ810M-E application, or VNQ810M-E equivalent, key selection criteria include per-channel current limiting (0.9A typ), thermal shutdown with 150°C trip point, reverse battery protection, ISO 7637-2 transient immunity, and status pin diagnostics for fault reporting in safety-critical 12V/24V systems.

Technical Context

The VNQ810M-E implements four independent high-side switches with CMOS-compatible inputs, open-drain status outputs, and dual-island thermal architecture enabling simultaneous operation of two channels per island. Each channel includes active current limiting, overtemperature shutdown with 15°C hysteresis, and undervoltage (4V typ) / overvoltage (36V) protection.

It supports open-load detection in both ON (20–80mA threshold) and OFF states (V_OL = 1.5–3.5V), detects output short-to-V_CC during OFF, and incorporates V_CC clamping for ISO 7637 pulse immunity. The device shuts down upon loss of ground connection and features <12µA standby current at 13V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5.5V to 36V DC - supports full automotive battery range including cold-crank and load-dump conditions.
R_DS(on)	150mΩ max @ 0.5A, 25°C - enables efficient 0.6A continuous switching with ≤450mW conduction loss per channel.
I_OUT Limit	0.7–1.4A - programmable current limit detects 21W/12V bulb as overload while avoiding nuisance trips.
T_J Shutdown	150°C trip, 135°C reset - thermal protection prevents latch-up during sustained overload or short-circuit events.
Status Output	Open-drain, 0.5V max @ 1.6mA - directly interfaces with 3.3V/5V microcontrollers for real-time fault reporting.
ISO 7637-2 Immunity	Pulse 1–5 compliant - withstands -100V/100ms (pulse 4), +86.5V/400ms (pulse 5), and 100V fast transients without functional interruption.
Reverse Battery	Withstands -0.3V V_CC; protected via external RGND resistor or DGND diode network per application schematic.

Pinout & Package

SO-28 package with double-island layout: two electrically isolated thermal islands (pins 1–14 and 15–28), each housing two high-side drivers with dedicated V_CC/GND pairs. Enables independent thermal management and fault containment between channel pairs.

Pin/Terminal	Circuit Role	Design Meaning
1, 14, 15, 28	V_CC1,2 / V_CC3,4	Supply pins for Island 1 (Ch1–2) and Island 2 (Ch3–4); each pair must be decoupled locally.
2, 3, 16, 17	GND1,2 / GND3,4	Isolated ground returns per island - critical for accurate current sensing and fault isolation.
4, 6, 18, 20	INPUT1–4	CMOS-compatible digital inputs (VIH=3.25V, VIL=1.25V); tolerate ±1mA clamp current.
5, 7, 19, 21	OUTPUT1–4	High-side switched outputs; drive grounded loads; support demagnetization clamping (V_demag = V_CC−41V).
8, 9, 22, 23	STATUS1–4	Open-drain diagnostic outputs - low = normal, high-impedance = fault (overload, open-load, overtemp).

Key Features

Feature	Design Value
Per-channel open-load detection in ON/OFF states	Enables pre-emptive fault identification before power-on and during sleep - eliminates need for external sense resistors.
Integrated V_CC clamp and transient protection	Meets ISO 7637-2 Pulse 1–5 without external TVS - reduces BOM count and PCB area in automotive ECUs.
Dual-island SO-28 thermal architecture	Allows independent thermal derating per island; supports 6.25W/ch power dissipation with 0.5cm² copper.
Loss-of-ground detection	Automatic shutdown if GND1,2 or GND3,4 disconnects - prevents uncontrolled load activation and system-level hazards.
Reverse battery protection support	Compatible with external RGND resistor or DGND diode networks - enables robust 12V/24V system survivability.

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
STSPIN840	Single-channel, 1.5A rated, SPI-controlled; no integrated open-load detection in OFF state.	Requires external status logic and MCU firmware overhead for diagnostics - unsuitable for passive fault monitoring.	Choose when precise current profiling and daisy-chain configuration are required over hardware-level diagnostics.
TPS27082L	Quad-channel, 0.7A, 36V, but lacks reverse-battery protection and ISO 7637-2 Pulse 5 compliance.	No integrated loss-of-ground detection or V_CC clamping - demands additional protection circuitry for automotive use.	Prefer for cost-sensitive non-automotive industrial applications where transient immunity is less stringent.

Compared with VNQ810M-E, STSPIN840 trades hardware diagnostics for programmability and higher current, while TPS27082L reduces integration depth to lower cost - neither matches the VNQ810M-E's combined fault coverage (open-load ON/OFF, loss-of-ground, reverse battery, ISO 7637) in a single quad-channel package.

FAQ

What is the maximum continuous output current per channel?

The VNQ810M-E supports 0.6A continuous DC output current per channel under typical conditions (T_j ≤ 125°C, 13V V_CC). Its current-limit threshold is 0.9A (typ), set to reliably detect 21W/12V incandescent bulbs as overloads while maintaining safe SOA during transient surges.

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

In OFF state, open-load detection requires an external pull-up resistor (R_PU) between OUTPUT and V_PU (e.g., +5V). When disconnected, V_OUT rises above 1.5–3.5V (V_OL threshold), triggering STATUS high-impedance. With load connected, V_OUT stays below this threshold due to leakage current (≤50µA), ensuring reliable discrimination.

Can VNQ810M-E drive inductive loads like solenoids?

Yes - it includes active demagnetization clamping (V_demag = V_CC−41V to V_CC−55V) and supports up to 174mJ switching energy (L = 310mH, V_bat = 13.5V). Thermal derating is required: with 6cm² copper per island, two channels can operate continuously at 0.6A without exceeding 150°C junction temperature.

Is VNQ810M-E still in active production?

No - STMicroelectronics has marked VNQ810M-E as obsolete (as noted in Table 2 and revision history). However, Aetrix Electronics maintains legacy inventory with full traceability and offers engineering support for migration paths to functionally aligned successors such as VNQ7E050AJ or VNQ860ESPTR-E where applicable.
