Product details

Overview

VNQ830P-E from STMicroelectronics is a quad-channel automotive-grade high-side driver IC built using VIPower™ M0-3 technology, integrating two VND830P-E dies in one SO-28 package. It delivers 6 A per channel, 65 mΩ R_DS(on), 36 V V_CC rating, and real-time open-load detection in both on/off states - deployed in body control modules for driving solenoids, relays, and LED arrays in 12 V/24 V vehicle electrical systems.

For engineers reviewing the VNQ830P-E datasheet, VNQ830P-E pinout, VNQ830P-E application, or VNQ830P-E equivalent, key selection criteria include thermal shutdown behavior, reverse battery protection implementation, status pin diagnostic logic, and load dump immunity per ISO 7637-2 Pulse 5a.

Technical Context

The device implements four independent high-side switches with CMOS-compatible inputs, each featuring active current limiting (6–15 A), thermal shutdown at 150–200 °C with 15 °C hysteresis, and dual-mode open-load detection: voltage threshold-based (≥2.5 V) in off-state and current threshold-based (50–200 mA) in on-state.

Protection architecture includes V_CC clamp diode (−41 to −55 V turn-off clamp), undervoltage lockout (4 V typ.), overvoltage shutdown (36 V), output stuck-to-V_CC detection, and electrostatic discharge resilience (5 kV on V_CC, 4 kV on input/status pins).

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 <1 W conduction loss at 6 A, reducing heatsink requirements
I_OUT max	6 A DC per channel - supports automotive solenoid and lamp loads without external current sharing
V_CC range	5.5 V to 36 V - compatible with 12 V and 24 V battery systems including cold-crank (5.5 V) and load-dump (36 V) transients
Open-load detection	On-state: 50–200 mA threshold; Off-state: 1.5–3.5 V threshold - enables fault isolation without external sense resistors
Thermal shutdown	150 °C trip, 135 °C reset with 15 °C hysteresis - prevents latch-up during sustained overload while allowing automatic recovery
Status pin logic	Active-low open-drain output with 0.5 V low-level voltage at 1.6 mA - directly interfaces with 3.3 V/5 V MCU GPIO for real-time diagnostics
ESD rating	5 kV HBM on V_CC, 4 kV on input/status pins - exceeds AEC-Q100 Class 3B requirements for under-hood environments

Pinout & Package

Package: SO-28 (Small Outline, 28-pin, 300 mil width), thermally enhanced with exposed thermal pad connected to GND - supports up to 6.25 W power dissipation per island at T_lead = 25°C.

Pin/Terminal	Circuit Role	Design Meaning
V_CC (pins 1, 2, 3, 4, 25, 26, 27, 28)	Power supply input	Eight parallel V_CC pins reduce IR drop and improve transient immunity; internal clamp diode protects against load dump
GND (pins 14, 15)	Ground reference	Dual GND pins minimize ground bounce; required for reverse battery protection network implementation
IN1–IN4 (pins 5, 6, 7, 8)	CMOS logic inputs	5 V tolerant, 0.5 V hysteresis - immune to noise in automotive harnesses; no external pull-ups needed
OUT1–OUT4 (pins 9, 10, 11, 12)	High-side switched outputs	Each drives grounded loads; integrated current limit and thermal foldback prevent destructive failure
ST1–ST4 (pins 16, 17, 18, 19)	Status outputs	Open-drain diagnostic signals indicating overload, overtemperature, open-load, or undervoltage - enable per-channel fault mapping
NC (pins 20–24)	No-connect	Internally unused; must be left floating or tied to GND via 10 kΩ resistor per datasheet Table 2

Key Features

Feature	Design Value
Quad-channel integration	Two VND830P-E dies in single SO-28 package - reduces PCB area by 40% vs discrete dual-channel solutions
Reverse battery protection	Supports external GND-line resistor/diode networks - eliminates need for upstream series MOSFET in cost-sensitive BCU designs
Load dump immunity	Withstands ISO 7637-2 Pulse 5a (+86.5 V, 400 ms) - meets OEM requirements for alternator-induced transients
Diagnostic granularity	Per-channel status pins report open-load, overcurrent, overtemperature, and undervoltage - enables precise software fault handling
Low standby current	12–40 μA at V_CC = 13 V - critical for always-on vehicle modules meeting ISO 16750 quiescent current limits

Applications

Body Control Module (BCM)

Engine Bay Power Distribution

Use Scenario: Controlling door locks, window lifts, and interior lighting in modern BCMs with centralized power switching.

IC Role / Device Role / Timing Role: High-side driver managing 12 V grounded loads; provides diagnostic feedback via STx pins to MCU every 200–1000 μs.

Use Value: Eliminates need for four separate single-channel drivers, reducing BOM count and enabling faster fault response than relay-based architectures.

Use Scenario: Switching radiator fans, fuel pumps, and HVAC actuators in engine compartment junction boxes.

IC Role / Device Role / Timing Role: Robust high-side switch with integrated reverse-battery and load-dump protection - operates reliably at 125 °C ambient.

Use Value: Withstands under-hood transients without external TVS, lowering system-level protection cost by ~$0.35 per channel.

Commercial Vehicle Lighting

Electric Power Steering (EPS) Auxiliary Loads

Use Scenario: Driving LED headlamps and DRLs in trucks and buses where EMI and thermal management are critical.

IC Role / Device Role / Timing Role: Constant-current capable high-side driver with open-load detection - ensures lamp integrity monitoring during PWM dimming.

Use Value: Detects broken LED strings in <1 ms, preventing false "lamp-out" warnings and supporting ASIL-B functional safety goals.

Use Scenario: Managing auxiliary solenoids and sensors in EPS control units requiring fail-safe power gating.

IC Role / Device Role / Timing Role: Safety-relevant high-side switch with thermal shutdown and status reporting - feeds diagnostic data to ASIL-C MCU via dedicated STx lines.

Use Value: Enables ISO 26262-compliant diagnostics without external current sense amplifiers or temperature sensors.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Single-channel, 160 mΩ R_DS(on), 2.5 A max, integrated charge pump - higher on-resistance, lower current rating	Requires four devices for quad functionality; lacks per-channel status pins - needs external logic for fault aggregation	Preferred when board space allows discrete layout and diagnostic depth is secondary to ultra-low quiescent current (1 μA)
BTS724G	Quad-channel, 100 mΩ R_DS(on), 3 A max, no off-state open-load detection - lower current capability, missing key diagnostic feature	Compatible pinout but requires external circuitry for off-state fault detection - increases design complexity and test coverage effort	Selected when cost is primary constraint and load types are purely resistive with predictable on-state behavior

Compared with TPS4H160-Q1 and BTS724G, the VNQ830P-E uniquely combines quad integration, 6 A per channel, full on/off open-load detection, and per-channel status reporting - making it optimal for ASIL-B body electronics where diagnostic completeness and thermal robustness are non-negotiable.

FAQ

What is the maximum continuous output current per channel?

The VNQ830P-E supports 6 A DC per channel under specified thermal conditions (T_case ≤ 100°C, PCB copper area ≥ 6 cm²). Current is internally limited to 6–15 A depending on V_CC and junction temperature, with automatic foldback during thermal events to prevent damage.

How does the off-state open-load detection work?

Off-state open-load detection monitors output voltage relative to GND while the channel is disabled. If V_OUT rises above 1.5–3.5 V (typ. 2.5 V), the status pin asserts low, indicating an open circuit. This occurs without external components and functions even with floating loads or disconnected wiring harnesses.

Can the VNQ830P-E drive inductive loads like solenoids safely?

Yes - the device integrates active demagnetization clamping (V_demag = V_CC − 41 to −55 V) and current limitation to safely handle inductive kickback. For L = 6 mH and I_L = 2 A, turn-off energy is absorbed internally without external snubbers, validated per ISO 7637-2 Pulse 5a.

Is the SO-28 package lead-free and RoHS compliant?

Yes - the VNQ830P-E carries ECOPACK® certification, confirming lead-free construction and full compliance with RoHS Directive 2011/65/EU and REACH regulations. The SO-28 package uses matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3).
