Product details
Overview
VNQ81013TR from STMicroelectronics is a quad-channel high-side driver IC designed for automotive and industrial load switching, featuring 160 mΩ RDS(on) per channel, 3.5 A continuous output current, 36 V supply voltage capability, and integrated open-load detection in both on/off states. It operates in SO-28 (double island) package and is used to drive grounded loads such as solenoids, relays, and lamps in body control modules.
For engineers reviewing the VNQ81013TR datasheet, VNQ81013TR pinout, VNQ81013TR application, or VNQ81013TR equivalent, key selection criteria include on-state resistance, short-circuit protection behavior, status pin logic compatibility with MCU GPIOs, and ISO 7637-2 transient immunity for 12 V/24 V vehicle systems.
Technical Context
The VNQ81013TR integrates two independent VND810 die in a single SO-28 double-island package, each die containing two high-side drivers with CMOS-compatible inputs and open-drain status outputs. Each channel implements active current limiting, thermal shutdown with hysteresis (150 °C trip / 135 °C reset), and loss-of-ground detection via internal sensing of GND pin disconnection.
It supports robust fault diagnostics: off-state open-load detection triggers when output voltage exceeds 1.5–3.5 V (indicating short-to-VCC), while on-state detection activates below 20–80 mA load current. The device includes VCC clamp for ISO 7637 pulse immunity and reverse-battery protection via external GND-line network.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 160 mΩ max per channel at IOUT = 1 A, Tj = 25 °C - ensures <1.1 W conduction loss at 3.5 A, enabling compact thermal design |
| IOUT continuous | 3.5 A per channel - supports automotive solenoid and lamp loads without external heatsinking under typical PCB copper area |
| VCC range | 5.5 V to 36 V - covers full automotive battery range including cold-crank (5.5 V) and load-dump (36 V) conditions |
| Undervoltage shutdown | 4 V typical - prevents erratic switching during battery brownout, ensuring safe turn-off before MCU logic fails |
| Open-load detection | On-state: 20–80 mA threshold; Off-state: 1.5–3.5 V threshold - enables reliable diagnostics without external sense resistors |
| Status output | Open-drain, 10 µA leakage max, 0.5 V low-level at 1.6 mA - directly interfaces with 3.3 V/5 V MCU inputs using pull-up resistor |
| ISO 7637-2 immunity | Level IV pulse 5 (86.5 V, 400 ms, 2 Ω) - meets OEM requirements for powertrain and chassis ECUs |
Pinout & Package
SO-28 package with double-island layout: two electrically isolated thermal islands (pins 1–14 and 15–28), each hosting two channels with dedicated VCC/GND pairs. Enables independent thermal management and fault isolation between channel pairs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1,2 | Supply for Channel 1 & 2 | Power input for first dual-channel island; must be decoupled locally to suppress transients |
| GND1,2 | Ground return for Channel 1 & 2 | Isolated ground pin pair - disconnecting either disables both channels in that island |
| INPUT1–4 | Digital enable inputs | CMOS-compatible (VIL ≤ 1.25 V, VIH ≥ 3.25 V); 0.5 V hysteresis prevents noise-induced toggling |
| OUTPUT1–4 | High-side switched outputs | Drives load between OUTPUTx and system ground; includes integrated clamp diode (VF = 0.6 V @ 0.5 A) |
| STATUS1–4 | Fault diagnostic outputs | Open-drain signals indicating overload, overtemperature, open-load, or undervoltage - pulled high externally |
| VCC3,4 / GND3,4 | Supply & ground for Channel 3 & 4 | Second isolated island - allows independent power domains or redundancy in safety-critical designs |
Key Features
| Feature | Design Value |
|---|---|
| Loss-of-ground protection | Automatic channel disable if GND1,2 or GND3,4 is disconnected - prevents uncontrolled load activation during wiring faults |
| Reverse battery protection support | Compatible with external GND-line resistor/diode networks (per Figure 24) - eliminates need for series MOSFET in cost-sensitive designs |
| Shorted-load recovery | Auto-restart after thermal shutdown with 20 µs status delay - maintains diagnostic visibility during fault cycling |
| Very low standby current | 12 µA max per island at VCC = 13 V - enables always-on modules (e.g., door ECU) without battery drain concerns |
| Demagnetization energy handling | VDEMAG = VCC − 41 V clamp - safely dissipates inductive kickback from 2.5 mH solenoids at 13.5 V battery |

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 |
|---|---|---|---|
| STVN810PTR | Single-channel version in PowerSSO-36; no integrated status pins; requires external fault monitoring | Lacks diagnostic capability; suitable only where diagnostics are handled at MCU level or omitted | Select when board space permits discrete channel placement and diagnostic overhead is acceptable |
| TPL7407LPWR | 7-channel NPN Darlington array; 500 mA per channel; no overvoltage/overtemperature protection | Lower current rating, no automotive-grade transient immunity or thermal shutdown | Use only in non-automotive 5 V logic-level applications with benign environments and external protection |
Compared with VNQ81013TR, STVN810PTR offers higher thermal performance per channel but sacrifices integration and diagnostics, while TPL7407LPWR provides channel count advantage at the cost of protection, voltage rating, and automotive qualification - making VNQ81013TR the sole choice for ISO 26262-compliant load switching.

FAQ
What is the thermal derating behavior above 100°C junction temperature?
RON increases linearly with temperature: from 160 mΩ at 25°C to ~320 mΩ at 150°C (Figure 17). Current limit also decreases - from 7.5 A at 25°C to 3.5 A at 125°C (Figure 13). Designers must apply PCB copper area ≥6 cm² per island to maintain Tj < 125°C at 3.5 A continuous per channel.
Can STATUS pins be tied together for consolidated fault reporting?
No - STATUS pins are open-drain but not internally OR'd. Connecting them risks contention if one channel reports fault (low) while another is idle (high-impedance). Each STATUS pin requires its own pull-up resistor and MCU GPIO input to preserve independent channel diagnostics.
Does VNQ81013TR support PWM dimming of LED loads?
Yes, with limitations: maximum switching frequency is ~5 kHz due to 30 µs turn-on/turn-off delays and thermal constraints. For LED drivers requiring >10 kHz PWM, external MOSFETs with faster gate drivers are recommended - VNQ81013TR is optimized for solenoid/relay actuation, not high-frequency LED modulation.
How does the device behave during battery reverse connection?
VNQ81013TR itself lacks internal reverse-polarity protection. However, it supports external reverse-battery networks per Figure 24: a 100 Ω resistor or Schottky diode in the GND line limits reverse current to safe levels (<200 mA absolute max per Table 3), preventing latch-up or damage when VCC is grounded and GND is positive.
