Product details

Overview

VNQ830 from STMicroelectronics is a quad-channel high-side driver IC designed for automotive and industrial load switching, featuring 65 mΩ R_DS(on) per channel, 6 A continuous output current, and 36 V supply voltage capability. It integrates two VND830 dies in a single SO-28 (double island) package and provides on/off-state open-load detection, short-circuit protection, loss-of-ground shutdown, and reverse-battery immunity - deployed in body control modules for driving solenoids, relays, and lamps.

For engineers reviewing the VNQ830 datasheet, VNQ830 pinout, VNQ830 application, or VNQ830 equivalent, key selection considerations include its dual-island thermal architecture, CMOS-compatible inputs with 0.5 V hysteresis, open-drain status outputs with 100 µA leakage max, and ISO 7637-2 transient compliance up to Level IV.

Technical Context

The VNQ830 implements four independent high-side switches using ST's VIPower™ M0-3 technology, each with integrated current limiting (6–15 A), thermal shutdown (150–200 °C trip), and undervoltage/overvoltage clamping (4–5.5 V UVSD, 36 V OVSD). Its dual-island SO-28 layout isolates channels into two thermally independent groups (pins 1–14 and 15–28), enabling parallel operation without thermal coupling.

Each channel supports diagnostic feedback via open-drain STATUS pins that indicate overload, overtemperature, open-load (on/off state), and supply faults. The device detects off-state shorts to V_CC at ≥1.5 V and on-state open loads at <100 mA, with status delay ≤200 µs for on-state and ≤1000 µs for off-state detection.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	65 mΩ per channel at I_OUT = 2 A, T_j = 25 °C - enables low conduction loss and <1 W dissipation at 6 A.
Continuous I_OUT	6 A per channel - supports automotive solenoids, fuel injectors, and HVAC actuators without external heatsinking under defined PCB copper area.
V_CC Range	5.5 V to 36 V - compatible with 12 V and 24 V vehicle battery systems including cold-crank (5.5 V) and load-dump (36 V) conditions.
Open-load Detection	On-state threshold: 50–200 mA; Off-state threshold: 1.5–3.5 V - enables reliable fault reporting for disconnected or broken-wire loads.
Thermal Shutdown	150 °C trip, 135 °C reset with 7–15 °C hysteresis - prevents latch-up during sustained overload and allows automatic recovery.
ISO 7637-2 Compliance	Level IV pulse 1, 2, 3a, 3b, 4, and 5 - withstands automotive transients including load dump (86.5 V, 400 ms) and jump-start (100 V, 2 ms).
Supply Current	12–40 µA quiescent (off-state); 5–7 mA active (on-state) - minimizes standby power in always-on vehicle modules.

Pinout & Package

SO-28 package with double-island thermal layout: two electrically isolated islands (pins 1–14 and 15–28), each containing two high-side channels, dedicated V_CC/GND pairs, and independent status outputs. Enables thermal separation and concurrent operation of two 2-channel subsystems.

Pin/Terminal	Circuit Role	Design Meaning
VCC1,2	Power supply input (Island 1)	Supplies both Channel 1 and Channel 2; clamped to 41 V absolute max; includes active clamp for ISO 7637 pulse 1/2.
GND1,2	Ground reference (Island 1)	Return path for Channels 1–2; loss-of-ground detection triggers immediate shutdown.
INPUT1–4	Digital control inputs	CMOS-compatible (V_IL ≤1.25 V, V_IH ≥3.25 V, 0.5 V hysteresis); tolerant of floating or 10 kΩ pull-down.
OUTPUT1–4	High-side switched outputs	Drives grounded loads; features integrated freewheeling diode (V_F ≤0.6 V @ 1.2 A, 150 °C).
STATUS1–4	Open-drain diagnostic outputs	Active-low reporting of fault conditions; requires external pull-up; leakage ≤10 µA, clamp ±0.7–8 V.
VCC3,4 / GND3,4	Power supply input (Island 2)	Independent supply for Channels 3–4; enables dual-domain power management and isolation.

Key Features

Feature	Design Value
Dual-island SO-28 thermal architecture	Two independent thermal islands (1–14 and 15–28) reduce cross-heating and enable 12 A total output with shared PCB copper area.
On/off-state open-load detection	Detects broken wires whether switch is energized (<100 mA) or de-energized (>1.5 V at output), eliminating need for external sense resistors.
Reverse battery protection	Withstands –0.3 V V_CC and –200 mA reverse ground current; supports GND-line resistor/diode protection networks per ST AN4229.
Integrated demagnetization clamp	V_DEMAG = V_CC – 41 to V_CC – 55 V - suppresses inductive kickback from solenoids and valves without external TVS.
Diagnostic-ready status outputs	Four open-drain STATUS pins report real-time faults (overload, overtemp, open-load, UV/OV) with <200 µs response - simplifies MCU firmware diagnostics.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN830	Single-channel version in SO-8; identical electrical specs but no dual-island thermal partitioning.	Limited to one load per package; unsuitable for space-constrained multi-channel designs requiring thermal independence.	Select when only one channel is needed and PCB area is constrained - avoids unused channels and simplifies layout.
Infineon BTS724G	Quad-channel HSD in PG-DSO-28; 100 mΩ R_DS(on), 4.5 A rating, and different status logic (push-pull vs. open-drain).	Lower current capacity and no off-state open-load detection; requires external pull-ups for status compatibility.	Choose where lower cost and Infineon ecosystem integration outweigh diagnostic depth and thermal margin requirements.

Compared with VNQ830, STVN830 trades channel density for compactness and simplified thermal design, while BTS724G offers functional parity at reduced performance margins and less comprehensive diagnostics - making VNQ830 optimal for safety-critical, multi-load automotive modules demanding full fault visibility.

FAQ

What is the maximum safe operating temperature for VNQ830?

The VNQ830 features internal thermal shutdown at 150–200 °C junction temperature, with automatic reset at 135 °C. Its SO-28 double-island package achieves R_thj-amb = 44 °C/W with 6 cm² PCB copper, allowing continuous 6 A operation at T_amb ≤ 85 °C under defined layout conditions - exceeding AEC-Q100 Grade 1 requirements.

Does VNQ830 require external components for basic operation?

VNQ830 operates with only external pull-up resistors on STATUS pins (typically 10 kΩ to V_CC) and appropriate PCB copper pour for thermal management. No external current-sense resistors, flyback diodes, or transient suppressors are required - all protections (open-load, overcurrent, overtemperature, UV/OV) and demagnetization clamping are fully integrated.

How does VNQ830 handle reverse battery connection?

VNQ830 tolerates –0.3 V on V_CC and –200 mA reverse current on GND pins. For full reverse-battery protection, ST recommends adding either a series resistor (R_GND) or Schottky diode (D_GND) in the ground path per Application Note AN4229 - enabling safe operation even if battery terminals are swapped during service.

Can VNQ830 drive inductive loads like solenoids without external protection?

Yes. VNQ830 integrates a V_F ≤ 0.6 V freewheeling diode and active demagnetization clamp (V_DEMAG = V_CC – 41 to V_CC – 55 V), enabling direct solenoid/valve driving. It also limits peak turn-off current per Figure 26 and withstands ISO 7637-2 Pulse 5 (86.5 V, 400 ms), eliminating need for external TVS or snubbers in most automotive cases.
