Product details

Overview

VNQ810MTR-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 features 150 mΩ R_DS(on) per channel, 0.6 A continuous output current, 36 V supply voltage rating, and integrated open-load detection in both on/off states. It is used in body control modules for driving lamps, solenoids, and relays.

For engineers reviewing the VNQ810MTR-E datasheet, VNQ810MTR-E pinout, VNQ810MTR-E application, or VNQ810MTR-E equivalent, key selection criteria include per-channel current limitation (0.9 A typ.), thermal shutdown with 150 °C trip point, reverse battery protection, ISO 7637-2 transient immunity, and status pin diagnostics for fault reporting.

Technical Context

The device integrates two independent VND810M-E dies in a single SO-28 "double island" package, enabling dual-channel thermal isolation. Each channel includes CMOS-compatible input logic, open-drain status output, active current limiting, and overtemperature/overvoltage/undervoltage shutdown.

It supports open-load detection in both ON state (20–80 mA threshold) and OFF state (1.5–3.5 V threshold), detects short-to-VCC in OFF state, and shuts down during loss-of-ground events. The internal V_CC clamp ensures compatibility with ISO 7637-2 Pulse 1, 2a, 3a/b, 4, and 5a transients.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	150 mΩ max at I_OUT = 0.5 A, T_j = 25 °C - enables low conduction loss for 12 V lamp loads up to 21 W.
I_OUT Continuous	0.6 A per channel - rated for standard automotive incandescent bulbs and small solenoids.
V_CC Range	5.5 V to 36 V - supports 12 V and 24 V vehicle electrical systems including cold-crank and load-dump conditions.
Current Limit Threshold	0.7–1.4 A - set to reliably detect 21 W/12 V bulb as overload while avoiding nuisance tripping.
Thermal Shutdown	150 °C trip, 135 °C reset - provides self-protection during sustained overload or poor PCB heatsinking.
Open-Load Detection	ON-state: 20–80 mA; OFF-state: 1.5–3.5 V - enables diagnostics without external circuitry beyond pull-up for OFF-state mode.
Status Output	Open-drain, 1.6 mA sink capability, 0.5 V low-level - compatible with 3.3 V/5 V microcontroller inputs for real-time fault reporting.

Pinout & Package

SO-28 "Double Island" package (JEDEC MS-013AC), with thermally isolated islands for channels 1–2 and 3–4. Exposed leadframe enhances thermal dissipation; recommended PCB copper area ≥6 cm² per island for full 0.6 A rating.

Pin/Terminal	Circuit Role	Design Meaning
1, 14, 15, 28	V_CC1,2 / V_CC3,4	Power supply inputs for each die island - must be decoupled locally; clamped to ~41 V for transient protection.
2, 3, 26, 27	GND1,2 / GND3,4	Ground returns per island - critical for reverse-battery protection and thermal isolation; not internally tied.
4, 7, 18, 21	INPUT1–4	CMOS-compatible digital inputs - accept 1.25 V low / 3.25 V high; include 0.5 V hysteresis for noise immunity.
5, 8, 19, 22	OUTPUT1–4	High-side switched outputs - drive grounded loads; feature demag clamp (V_CC−41 V) during inductive turn-off.
6, 9, 20, 23	STATUS1–4	Open-drain diagnostic outputs - pulled low during overtemperature, overvoltage, undervoltage, open-load, or short-circuit.

Key Features

Feature	Design Value
Per-channel open-load detection in ON and OFF states	Enables full-cycle diagnostics without external sensing - reduces BOM count and improves system reliability in lighting and valve control.
Reverse battery protection	With external ground-line resistor or diode network - prevents damage during incorrect battery connection in automotive service environments.
ISO 7637-2 transient immunity	Passes all five test pulses (Class C) - eliminates need for external TVS on V_CC in most 12 V vehicle applications.
Integrated thermal shutdown with hysteresis	150 °C trip / 135 °C reset (15 °C hysteresis) - avoids oscillation during marginal thermal conditions and enables safe automatic recovery.
Low standby current	12 µA typical per island at V_CC = 13 V - meets automotive "off-mode" current budgets for always-on modules.

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
STSPIN250TR	Single-channel, 1.2 A rated, integrated current sense analog output - no status pin or open-load detection.	Requires external logic for multi-channel coordination and lacks diagnostic reporting capability.	Choose when precise current measurement is prioritized over fault diagnostics and compact channel count.
TLE7234SE	Quad-channel, 0.5 A, 40 V, but uses different protection architecture - no OFF-state open-load detection, no reverse-battery tolerance.	Lacks OFF-state diagnostics and requires external reverse-polarity protection circuitry.	Prefer when cost sensitivity outweighs need for comprehensive fault coverage in non-automotive 24 V systems.

Compared with VNQ810MTR-E, STSPIN250TR offers higher current and analog sensing but sacrifices integration and diagnostics; TLE7234SE matches channel count and voltage rating but omits critical automotive-grade protections and diagnostic modes required for OEM compliance.

FAQ

What is the maximum continuous output current per channel?

The VNQ810MTR-E supports 0.6 A continuous output current per channel under specified thermal conditions (T_lead = 25 °C, 6 cm² copper per island). Derating applies above 25 °C ambient or with reduced PCB copper area; the internal current limiter activates at 0.7–1.4 A depending on junction temperature and supply voltage.

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

OFF-state open-load detection requires an external pull-up resistor (R_PU) between OUTPUT and a positive supply (e.g., +5 V). When the load is disconnected, the output floats high (>1.5 V); when connected, it pulls low (<3.5 V). The STATUS pin goes low if V_OUT exceeds the VOL threshold, signaling an open condition.

Is reverse battery protection built-in or external?

Reverse battery protection is not fully internal - it requires an external network: either a series resistor (R_GND) or Schottky diode (D_GND) in the ground path. The device tolerates −0.3 V on V_CC and −200 mA on GND pins, but sustained reverse polarity demands external mitigation per Figure 8 in the datasheet.

Can VNQ810MTR-E drive inductive loads like solenoids?

Yes - it includes active demagnetization clamping (V_demag = V_CC − 41 V) and supports inductive turn-off energy up to 174 mJ (L = 310 mH, I_L = 0.9 A). For repetitive inductive switching, thermal design must account for peak power dissipation and ensure junction temperature remains below 150 °C.
