Product details
Overview
VND810 from STMicroelectronics is a double-channel high-side driver IC designed for automotive and industrial load control, featuring 160 mΩ RDS(on) per channel, 3.5 A continuous output current, 36 V supply voltage rating, CMOS-compatible inputs, and open-drain status outputs. It drives grounded loads in body electronics, lighting, and solenoid control with integrated on/off-state open-load detection, short-circuit protection, and loss-of-ground shutdown.
For engineers reviewing the VND810 datasheet, VND810 pinout, VND810 application, or VND810 equivalent, key selection considerations include its dual-channel high-side topology, ISO7637-2 transient immunity, thermal shutdown with hysteresis, reverse battery protection capability, and diagnostic status signaling for fault-aware system design.
Technical Context
The VND810 integrates two independent VIPower M0-3 high-side switches with active current limiting (5.5–7.5 A), thermal shutdown at 150–200 °C, and automatic restart. Each channel features dedicated input logic, output driver, and status pin with open-drain configuration.
It implements dual-mode open-load detection: during ON-state via output current threshold (20–80 mA), and OFF-state via output voltage threshold (1.5–3.5 V). Protection functions include undervoltage (4 V typ) and overvoltage (36 V) shutdown, reverse battery tolerance via GND-line network, and VCC-clamp against low-energy transients per ISO7637.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 160 mΩ per channel at 1 A, 25 °C - enables low conduction loss and minimal self-heating under 3.5 A load |
| IOUT | 3.5 A continuous per channel - supports automotive lamps, valves, and small motors without external heatsinking |
| VCC | 36 V max operating voltage - compatible with 24 V commercial/industrial systems and withstands load-dump transients |
| Open-load detection | Active in both ON-state (20–80 mA threshold) and OFF-state (1.5–3.5 V threshold) - enables full-cycle diagnostics without external circuitry |
| Status output | Open-drain, clamped to 6–8 V - allows direct interface with 3.3 V/5 V MCU GPIOs using pull-up resistor |
| Thermal shutdown | 150 °C trip, 135 °C reset with 15 °C hysteresis - prevents latch-up and enables safe recovery after overload |
| ISO7637-2 compliance | Pulse 1 (−100 V), Pulse 2a (+100 V), Pulse 3b (+100 V) - meets automotive EMC requirements without additional TVS |
Pinout & Package
Package: SO-16 (Small Outline, 16-pin, 1.27 mm pitch), RoHS-compliant ECOPACK®.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VCC | Power supply input (dual pins for current sharing and reduced thermal resistance) |
| 2, 10 | GND | Ground reference (dual pins for low-impedance return path and thermal dissipation) |
| 3, 11 | INPUT1 / INPUT2 | CMOS-compatible digital control inputs (VIL = 1.25 V, VIH = 3.25 V) |
| 4, 12 | OUTPUT1 / OUTPUT2 | High-side switched outputs - connect to load anode; load cathode to ground |
| 5, 13 | STATUS1 / STATUS2 | Open-drain diagnostic outputs - pulled low during fault (overload, open load, UV/OV, overtemp) |
| 6, 7, 14, 15 | N.C. | No-connect pins - must be left floating or tied to ground per datasheet Table 2 |
| 8, 16 | VCC / GND | Secondary VCC and GND pins - electrically identical to pins 1/2 and 9/10; used for PCB layout symmetry and thermal relief |
Key Features
| Feature | Design Value |
|---|---|
| On/Off-state open-load detection | Eliminates need for external sense resistors or ADC monitoring - reduces BOM count and improves system-level diagnostic coverage |
| Loss-of-ground protection | Automatic shutdown when GND pin disconnects - prevents uncontrolled output leakage and ensures fail-safe behavior in wiring faults |
| Reverse battery protection support | Enables robust operation with external RGND resistor or DGND diode network - protects against −14 V reverse polarity events |
| Very low standby current | 12 µA typical at 13 V - suitable for always-on vehicle modules requiring <100 µA total quiescent draw |
| Integrated VCC clamp | Clamps transients up to 41 V peak - satisfies ISO7637 Pulse 1/2a/3b without external TVS diodes |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Output Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN840 | Single-channel, integrated current-sense amplifier, SPI interface, lower RDS(on) (120 mΩ), no off-state open-load detection | Targeted at closed-loop motor control, not discrete load switching | Select when precise current feedback and digital configurability outweigh dual-channel simplicity |
| TLE7231G | Single-channel, 3.2 A, 40 V, includes PWM input support and enhanced ESD (6 kV HBM), no reverse battery protection network guidance | Optimized for 12 V automotive lighting with fast PWM dimming | Select for high-frequency switching (>1 kHz) or where higher ESD robustness is mandatory |
Compared with STSPIN840 and TLE7231G, the VND810 uniquely delivers dual-channel integration with comprehensive diagnostic coverage (on/off open-load, loss-of-ground, UV/OV) in a cost-optimized SO-16 package-making it optimal for space-constrained, fault-tolerant discrete load control rather than motor or PWM-centric applications.

FAQ
What is the maximum continuous output current per channel?
The VND810 supports 3.5 A continuous output current per channel at Tj ≤ 150 °C with adequate PCB copper area (≥4 cm² per VCC pin). Derating applies above 100 °C junction temperature; full 3.5 A is guaranteed only with proper thermal layout per datasheet Figure 28.
How does the off-state open-load detection work?
When the input is low, the device monitors output voltage: if VOUT rises above 1.5–3.5 V (depending on temperature), the corresponding STATUS pin pulls low. This detects broken wires or disconnected loads while the channel is inactive-no external biasing required beyond the standard pull-up resistor on STATUS.
Can VND810 drive inductive loads like solenoids or relays?
Yes-the VND810 includes internal demagnetization clamping (Vdemag = VCC − 41 V to VCC − 55 V) and handles up to 26 mJ switching energy (L = 1.5 mH, IL = 5 A). External flyback diodes are unnecessary, but PCB layout must minimize parasitic inductance in the output loop.
Is VND810 still in active production?
The VND810 is marked "Obsolete Product(s)" in ST's official documentation (Rev 3, Dec 2008), but remains available through authorized distributors and Aetrix Electronics' legacy component program with full traceability, extended lifecycle support, and engineering assistance for continuity in existing designs.
