Product details

Overview

VNQ830E from STMicroelectronics is a quad-channel high-side driver IC fabricated in VIPower M0-3 technology, designed for automotive and industrial load switching with ground-referenced loads. It integrates two VND830-E dies in a single SO-28 double-island package, delivering 6 A per channel, 60 mΩ R_DS(on), and 36 V V_CC rating. Key protections include on/off-state open-load detection, short-to-V_CC fault recognition, thermal shutdown with 150 °C trip point, reverse battery protection, and ISO 7637-2 transient immunity.

For engineers reviewing the VNQ830E datasheet, VNQ830E pinout, VNQ830E application, or VNQ830E equivalent, this device is selected for robust 12 V/24 V automotive body control modules (BCM), smart junction boxes, and industrial PLC output stages requiring diagnostic feedback, fail-safe operation, and high-current drive without external current-sensing components.

Technical Context

The VNQ830E implements four independent high-side switches with CMOS-compatible inputs and open-drain status outputs per channel. Each channel features active current limiting (6–15 A), undervoltage (4 V typ.) and overvoltage (36 V) shutdown, loss-of-ground detection, and dual-mode open-load sensing-using internal comparators to detect >100 mA load current in ON state and >1.5 V floating output voltage in OFF state with external pull-up.

Its SO-28 double-island package thermally isolates two dual-channel islands, enabling independent thermal management: each island supports 6.25 W power dissipation at T_lead = 25 °C, with R_thj-amb of 44 °C/W (one channel ON, 6 cm² copper) and 31 °C/W (two channels ON, same condition). The integrated V_CC clamp handles ISO 7637 Pulse 1 (−100 V), Pulse 2a (+100 V), and Pulse 5a (+86.5 V) transients.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5.5 V to 36 V DC - supports full automotive battery range including cold-crank (5.5 V) and load-dump (36 V) conditions
R_DS(on)	60 mΩ max @ I_OUT = 2 A, T_j = 25 °C - enables <1.5 W conduction loss per channel at 6 A
I_OUT Continuous	6 A per channel - rated for sustained current in BCM headlight or pump drivers
Open-Load Detection	ON state: 50–200 mA threshold; OFF state: 1.5–3.5 V threshold - enables diagnostics without external sense resistors
Thermal Shutdown	150 °C trip, 135 °C reset with 15 °C hysteresis - prevents latch-up during overload and allows automatic recovery
Status Output	Open-drain, 1.6 mA sink capability, 0.5 V low-level - directly interfaces with 3.3 V/5 V microcontroller GPIOs
ISO 7637-2 Immunity	Pulse 1 to 5 validated - eliminates need for external TVS on V_CC in standard automotive designs

Pinout & Package

Package: SO-28 double-island (SO-28DI), 18.1 mm × 10.65 mm × 2.65 mm body, 1.27 mm pitch, 0.4–1.27 mm lead length, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1, 14, 15, 28	V_CC1,2 / V_CC3,4	Power supply pins for two independent islands - must be decoupled locally; shared V_CC routing allowed only within same island
2–5, 16–19	INPUT1–4	CMOS-compatible digital inputs - accept 1.25 V low / 3.25 V high; 0.5 V hysteresis prevents noise-induced toggling
6–9, 20–23	OUTPUT1–4	High-side switched outputs - connect to load anode; support inductive demagnetization via internal clamp
10–13, 24–27	STATUS1–4	Open-drain diagnostic outputs - pulled low during overload, overtemperature, undervoltage, or open-load events
11, 12, 25, 26	GND1,2 / GND3,4	Island-specific ground returns - mandatory separation between islands to maintain thermal independence and fault isolation

Key Features

Feature	Design Value
Integrated reverse battery protection	Withstands −0.3 V V_CC and −200 mA reverse ground current - eliminates need for external series diode in battery feed
Dual-mode open-load detection	Active in both ON (current-based) and OFF (voltage-based) states - enables full-cycle diagnostics without external circuitry
Loss-of-ground fault detection	Automatic shutdown if GND pin disconnects - prevents uncontrolled output turn-on and system-level safety hazard
Low standby current	12 µA typical per island - meets automotive "off" current budgets (<100 µA) when inputs held low
V_CC transient clamping	Clamps ISO 7637 Pulse 1 (−100 V) and Pulse 5a (+86.5 V) - reduces external protection component count by ≥3 devices

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Single-channel, 5 A, 45 V, integrated current sense and PWM control - lacks open-load OFF-state detection and double-island thermal separation	Targeted at motor gate drivers, not multi-load switching - requires external logic for quad-channel coordination	Choose for brushed DC motor control where current regulation and PWM are needed; avoid for BCM-style discrete load switching.
TPS27082L	Quad-channel, 3.6 A, 36 V, no integrated open-load OFF detection or reverse battery protection - relies on external components for those functions	Designed for space-constrained consumer electronics - lacks ISO 7637-2 validation and automotive qualification	Consider only for non-automotive industrial use with simplified protection requirements and lower current demand.

Compared with STSPIN250 and TPS27082L, the VNQ830E uniquely delivers quad-channel integration with full automotive-grade diagnostics (ON/OFF open-load, loss-of-ground, reverse battery), double-island thermal resilience, and ISO 7637-2 compliance - making it the sole option for ASIL-QM body control modules requiring zero external protection components.

FAQ

What is the maximum continuous output current per channel?

The VNQ830E supports 6 A continuous output current per channel under specified thermal conditions: T_lead = 25 °C, 6 cm² PCB copper per island, horizontal mounting. Derating applies above 25 °C ambient - at 100 °C ambient, max current drops to ~3.5 A due to thermal limits and 150 °C junction shutdown threshold.

How does off-state open-load detection work, and what external components are required?

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 above 1.5 V, triggering STATUS low. R_PU must satisfy: R_PU < (V_PU – 3.5 V) / |I_L(off2)| and R_PU > V_PU·R_L / (V_OLmin – R_L), where I_L(off2) ≤ 75 µA and V_OLmin = 1.5 V per datasheet Table 10.

Does the VNQ830E require external flyback diodes for inductive loads?

No external flyback diode is required. The VNQ830E integrates internal demagnetization clamps that limit V_OUT to V_CC – 41 V during turn-off (Table 7), safely dissipating energy from inductive loads like solenoids and relays. This eliminates board space and cost for discrete clamp diodes while maintaining consistent turn-off timing.

Can unused INPUT and STATUS pins be left floating?

Unused INPUT pins may be left unconnected per datasheet Figure 3 note, but STATUS pins must not float - they are open-drain and require external pull-up resistors (typically 4.7 kΩ to 10 kΩ) to a valid logic supply to ensure defined high-state behavior during normal operation and fault reporting.
