Product details

Overview

VNQ810M13TR from STMicroelectronics is a quad-channel high-side driver IC in SO-28 (double island) package, designed for automotive and industrial load switching with ground-referenced loads. It integrates two VND810M VIPower M0-3 chips, delivering 0.6A per channel, 150mΩ R_DS(on), 36V V_CC max, and real-time open-load detection in both on/off states - used in body control modules for headlight, fog light, and HVAC blower control.

For engineers reviewing the VNQ810M13TR datasheet, VNQ810M13TR pinout, VNQ810M13TR application, or VNQ810M13TR equivalent, key selection criteria include channel count, integrated diagnostics (open-load, overtemperature, overvoltage), reverse battery protection, ISO 7637-2 transient immunity, and thermal derating behavior under multi-channel simultaneous conduction.

Technical Context

The VNQ810M13TR implements four independent high-side switches with CMOS-compatible inputs and open-drain status outputs per channel. Each channel features active current limitation (0.9A typ at 13V), thermal shutdown (150°C trip), undervoltage (4V) and overvoltage (36V) shutdown, plus loss-of-ground detection via internal sensing of GND pin disconnection.

Its dual-island SO-28 layout isolates two pairs of channels thermally and electrically, enabling independent thermal management per island. The device uses VIPower M0-3 technology to integrate power DMOS with smart logic, diagnostic circuitry, and clamping diodes - supporting robust 12V/24V automotive systems without external protection components.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5.5V to 36V - supports full automotive battery range including cold-crank (5.5V) and load-dump transients (up to 41V absolute max).
R_DS(on) per Channel	150mΩ @ I_OUT = 0.5A, T_j = 25°C - enables <1W conduction loss at 0.6A, critical for thermally constrained PCB layouts.
Output Current Limit	0.9A typical @ V_CC = 13V - set to reliably detect 21W/12V incandescent bulbs as overload faults.
Open-Load Detection	On-state: 20–80mA threshold; Off-state: 1.5–3.5V threshold - allows diagnostics without load energization or external sense resistors.
Status Output Type	Open-drain with 6.8V clamp - compatible with 3.3V/5V MCU I/O, supports wired-OR fault aggregation across all four channels.
Thermal Shutdown	150°C trip, 135°C reset with 15°C hysteresis - prevents latch-up during sustained overload while enabling automatic recovery after cooling.
ISO 7637-2 Immunity	Class C performance across all pulses (1–5) - meets OEM requirements for direct battery-connected ECUs without additional TVS or RC networks.

Pinout & Package

SO-28 package with double-island thermal construction: two independent thermal islands (pins 1–14 and 15–28), each hosting two high-side drivers, their inputs, status outputs, and shared V_CC/GND pins. Enables parallel operation of two channels per island with optimized thermal dissipation.

Pin/Terminal	Circuit Role	Design Meaning
V_CC1,2	Power supply for Island 1	Supplies both CH1 and CH2; must be decoupled locally; supports up to 41V transient.
GND1,2	Ground reference for Island 1	Loss-of-ground detection enabled; disconnect triggers immediate channel disable and status flag.
INPUT1–4	CMOS logic input per channel	VIH = 3.25V, VIL = 1.25V, hysteresis = 0.5V - immune to noisy 12V system noise when driven via resistor divider.
OUTPUT1–4	High-side switched output	Drives load between OUTPUTx and chassis ground; includes V_CC-to-output clamp diode (VF = 0.6V @ 0.53A).
STATUS1–4	Open-drain diagnostic output	Pulled low on fault (overload, overtemp, open-load, UV/OV); 6.8V clamp protects MCU I/O.
V_CC3,4	Power supply for Island 2	Independent supply for CH3/CH4; allows split-bus or redundancy schemes.
GND3,4	Ground reference for Island 2	Separate GND path enables isolation of ground faults per island.

Key Features

Feature	Design Value
Integrated open-load detection (on/off)	Eliminates need for external current-sense resistors or auxiliary comparators in bulb monitoring applications.
Reverse battery protection	Withstands -14V applied to V_CC (per datasheet Figure 24 schematic using DGND or R_GND), protecting downstream loads.
Active current limitation + thermal shutdown	Combines fast electronic current foldback (µs response) with thermal cutoff to prevent bond-wire fusing during short circuits.
ISO 7637-2 compliant transient immunity	Passes Pulse 1 (−100V), Pulse 2 (+100V), Pulse 3b (+100V), and Pulse 5 (+86.5V) without latch-up or parameter shift.
Very low standby current	12µA typical @ V_CC = 13V - meets automotive "parking mode" current budgets (<50µA) for always-on ECUs.

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
STVN810M13TR	Single-channel version in SO-8; identical electrical specs per channel but no multi-channel integration.	Requires 4× ICs + extra PCB area and routing; lacks inter-channel synchronization or shared diagnostics.	Select when thermal constraints prohibit SO-28 or when channel independence is mandatory for safety isolation.
Infineon BTS716G	Quad high-side with 140mΩ R_DS(on), 2.2A current limit, and SPI interface; no off-state open-load detection.	Supports advanced diagnostics via serial interface but requires MCU firmware support; higher current rating suits larger loads.	Select when digital communication, higher drive capability, or ASIL-B functional safety certification is required.

Compared with STVN810M13TR, the VNQ810M13TR saves 75% board space and simplifies layout with integrated dual-island thermal management; versus BTS716G, it offers superior off-state diagnostics and lower system-level BOM cost but lacks SPI configurability and ASIL compliance.

FAQ

What is the maximum continuous output current per channel?

The VNQ810M13TR supports 0.6A DC output current per channel under typical operating conditions (T_j ≤ 125°C, V_CC = 13V). Its current limitation threshold is 0.9A typical, set to detect 21W/12V bulbs as overloads. Derating is required above 100°C junction temperature per thermal data in Table 4.

Does the device support PWM dimming of LED loads?

Yes - the VNQ810M13TR supports PWM switching up to 5kHz (per datasheet Figure 5 rise/fall times of ~30µs), with controlled dV/dt to minimize EMI. However, LED loads require external freewheeling paths due to lack of internal flyback diodes; the V_demag clamp (V_CC − 48V) handles inductive kickback from associated drivers or transformers.

How does loss-of-ground protection work?

The device continuously monitors voltage drop across internal sense elements between GND pins and substrate. If GND1,2 or GND3,4 disconnects, the corresponding island disables all outputs within microseconds and pulls its STATUS pins low. This prevents uncontrolled floating outputs and ensures fail-safe behavior in chassis-ground fault scenarios.

Is the VNQ810M13TR still in active production?

No - STMicroelectronics has marked the VNQ810M13TR as obsolete (per DocID7388 Rev 4, page 1). Aetrix Electronics maintains legacy inventory and provides last-time-buy support, including full traceability, extended warranty, and cross-reference assistance for migration to STVN810M13TR or BTS716G where applicable.
