Product details

Overview

VNQ810PTR-E from STMicroelectronics is a quad-channel automotive-grade high-side driver IC built with VIPower™ M0-3 technology in SO-28 (double island) package, delivering 3.5 A per channel, 160 mΩ R_DS(on), and 36 V V_CC rating. It drives grounded loads in vehicle body control modules, lighting systems, and HVAC actuators with integrated open-load detection (on/off-state), thermal shutdown, reverse battery protection, and ISO 7637-2 transient immunity.

For engineers reviewing the VNQ810PTR-E datasheet, VNQ810PTR-E pinout, VNQ810PTR-E application, or VNQ810PTR-E equivalent, key selection criteria include per-channel current limiting (3.5 A typ.), dual-island SO-28 thermal performance, CMOS-compatible inputs, status pin diagnostics, and AEC-Q100 compliance for under-hood deployment.

Technical Context

The device integrates two independent VND810P-E dies in one SO-28 package, each die forming two high-side channels with shared V_CC/GND islands. Each channel features active V_CC clamp (V_OV = 36 V), undervoltage lockout (V_USD = 4 V typ.), and output stuck-to-V_CC detection during off-state.

Diagnostic architecture includes four dedicated STATUS pins (one per channel), supporting real-time fault reporting for overtemperature (T_TSD = 150 °C), overcurrent (I_LIM = 3.5 A), open-load (V_OL = 2.5 V typ. off-state), and undervoltage conditions via configurable logic-level outputs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5.5–36 V: Supports full automotive battery range including cold-crank (5.5 V) and load-dump transients (up to 41 V abs max).
R_DS(on) per Channel	160 mΩ @ T_j = 25 °C: Enables <1.2 W conduction loss at 3 A, critical for thermally constrained PCB layouts.
Output Current Limit	3.5 A typ.: Internally set current limit prevents wire/connector damage during short-circuit events without external sensing.
Open-Load Detection	On-state: 40 mA threshold; Off-state: 2.5 V threshold - enables reliable bulb-out detection in lighting control without external circuitry.
Thermal Shutdown	150 °C trip / 135 °C reset: Hysteresis ensures stable recovery after overload, avoiding oscillation during thermal stress.
Status Pin Logic	Active-low open-drain: Directly interfaces with 3.3 V/5 V MCU GPIOs; internal 10 kΩ pull-up recommended per ST application note.
ISO 7637-2 Immunity	Class C for pulses 1–4; Class E only for pulse 5: Withstands 100 ms 7 V surge (pulse 4) and 400 ms 86.5 V load dump (pulse 5a) when used with external clamping.

Pinout & Package

SO-28 package with double island layout: two electrically isolated thermal islands (V_CC1,2/GND_1,2 and V_CC3,4/GND_3,4) enable independent power domain management and enhanced thermal dissipation (R_thj-amb = 44 °C/W with 6 cm² copper).

Pin	Circuit Role	Design Meaning
1, 14, 15, 28	V_CC supply (dual island)	Pins 1 & 14 connect to first island (CH1–CH2); pins 15 & 28 to second island (CH3–CH4); decoupling required per island.
2, 3, 4, 5, 16, 17, 18, 19	OUTPUT (CH1–CH4)	High-side switched outputs; each drives load between pin and ground; supports inductive demagnetization clamp (V_demag = V_CC−48 V).
6, 7, 20, 21	INPUT (CH1–CH4)	CMOS-compatible digital inputs (V_IH = 3.25 V, V_IL = 1.25 V); hysteresis = 0.5 V prevents noise-induced switching.
8, 9, 22, 23	STATUS (CH1–CH4)	Open-drain diagnostic outputs; low = fault (overtemp, overcurrent, open-load, UV); requires external pull-up resistor.
10, 11, 24, 25	GND (dual island)	GND_1,2 (pins 10,11) serves CH1–CH2; GND_3,4 (pins 24,25) serves CH3–CH4; separation reduces ground bounce coupling.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 1 (−40 °C to +125 °C ambient) with full traceability and PPAP support for Tier-1 production.
Dual-island thermal architecture	Two independent SO-28 thermal islands reduce mutual heating; enables 6.25 W power dissipation per island at T_lead = 25 °C.
Reverse battery protection	Withstands −200 mA reverse GND current; eliminates need for external series diode in battery-reversal-prone applications.
Integrated V_CC clamp	Active clamp limits V_CC to ≤41 V during transients (ISO 7637 pulse 1/2/3a/3b), protecting internal circuitry without external TVS.
Low standby current	12 µA typical (V_CC = 13 V, all inputs low): Meets stringent automotive sleep-mode current budgets (<50 µA).

Applications

Automotive Lighting Control

Body Control Module (BCM)

Use Scenario: Driving LED headlamps, fog lamps, and turn signals with real-time open-circuit monitoring.

IC Role / Device Role / Timing Role: High-side switch with on-state open-load detection (40 mA threshold) and status feedback to MCU for lamp failure reporting.

Use Value: Eliminates external current-sense resistors and comparator circuits; reduces BOM count by 3–5 components per channel.

Use Scenario: Controlling door locks, window lift motors, and mirror actuators in centralized BCM units.

IC Role / Device Role / Timing Role: Quad-channel load driver with thermal shutdown and reverse-battery immunity for under-dash mounting.

Use Value: Dual-island SO-28 layout isolates motor drive heat from logic sections, maintaining signal integrity across 10+ controlled functions.

HVAC Blower & Valve Actuation

Engine Bay Auxiliary Loads

Use Scenario: Switching 12 V DC blower fans and stepper-motor-driven air flaps in climate control systems.

IC Role / Device Role / Timing Role: High-side driver with off-state open-load detection (2.5 V threshold) to verify actuator coil continuity before startup.

Use Value: Prevents false "stuck" faults during cold start; enables predictive maintenance alerts via STATUS pin sequencing.

Use Scenario: Powering radiator fans, fuel pump relays, and turbocharger oil pumps exposed to under-hood temperatures.

IC Role / Device Role / Timing Role: AEC-Q100 qualified quad driver with 150 °C thermal shutdown and ISO 7637-2 pulse 5 immunity (with external clamp).

Use Value: Sustains operation at 125 °C ambient while delivering 3.5 A continuous; avoids derating penalties common with non-automotive drivers.

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
TPS4H160-Q1	Single-die quad driver (not dual-die); lower R_DS(on) (120 mΩ); no off-state open-load detection.	Lacks off-state V_OL threshold; requires external voltage divider for bulb-out detection in lighting.	Preferred for space-constrained designs needing lower conduction loss but accepting added external components for diagnostics.
BTS716G	Quad high-side with integrated charge pump; higher I_OUT (6 A); no dual-island thermal separation.	Higher thermal coupling between channels limits simultaneous full-load operation in compact layouts.	Chosen when peak current >3.5 A is required and PCB copper area allows single-island thermal management.

Compared with TPS4H160-Q1 and BTS716G, the VNQ810PTR-E uniquely combines dual-island thermal isolation, comprehensive open-load detection (both states), and AEC-Q100-compliant transient immunity in a single SO-28 footprint-making it optimal for safety-critical, multi-function automotive modules where channel independence and diagnostic completeness are mandatory.

FAQ

What is the maximum continuous output current per channel?

The VNQ810PTR-E delivers 3.5 A typical continuous output current per channel at T_j = 25 °C with adequate PCB copper (6 cm² per island). Derating applies above 25 °C ambient: current limit drops to ~2.2 A at 100 °C case temperature per Figure 14 in the datasheet. This value is internally set and does not require external adjustment.

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

Off-state open-load detection monitors output voltage when the channel is disabled (INPUT = low). If V_OUT rises above 2.5 V (typical), the STATUS pin pulls low to indicate an open circuit. This occurs because leakage current through the load path is insufficient to pull the output to ground, enabling bulb-out detection without powering the load.

Can the VNQ810PTR-E drive inductive loads like solenoids or relays?

Yes-the device includes active demagnetization clamping (V_demag = V_CC−48 V) and supports up to 23 mJ switching energy (L = 2.5 mH, I_L = 9 A). For relay coils, ensure flyback energy stays within this limit; larger inductors require external snubbers or clamps per Section 3.5 of the datasheet.

Is the SO-28 "double island" package compatible with standard SO-28 footprints?

Yes-the mechanical dimensions match JEDEC MS-013AC (SO-28), but thermal islands require separate copper pours for V_CC1,2/GND_1,2 and V_CC3,4/GND_3,4. Pin 1–14 and 15–28 must be routed to distinct power/ground planes to maintain isolation; mixing islands compromises thermal and fault containment benefits.
