Product details
Overview
VND830LSP-E from STMicroelectronics is a high-side smart power switch IC designed for automotive and industrial load control, featuring 3.4 A continuous current rating, 40 V maximum supply voltage, integrated thermal shutdown, overcurrent protection, and diagnostic feedback via open-drain output. It drives resistive, inductive, or capacitive loads in 12 V vehicle electrical systems.
For engineers reviewing the VND830LSP-E datasheet, VND830LSP-E pinout, VND830LSP-E application, or VND830LSP-E equivalent, key selection criteria include its embedded protection architecture, diagnostic flag timing behavior, SO-16 package thermal performance, and compliance with automotive-grade AEC-Q100 Grade 1 specifications.
Technical Context
This device integrates a vertical Power MOSFET with analog current sensing, thermal foldback, and digital logic for fault detection and reporting. Its internal charge pump enables full enhancement of the N-channel output stage without external bootstrap components.
The IC operates across −40 °C to +150 °C ambient temperature, supports PWM switching up to 20 kHz, and provides accurate current-limit threshold (3.4 A ±15%) with fast response (< 2 µs) to short-circuit events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 28 V - compatible with 12 V automotive battery systems including cold-crank and load-dump transients |
| Continuous Output Current | 3.4 A - sufficient for driving solenoids, relays, lamps, and small motors without external heatsinking |
| On-State Resistance (RDS(on)) | 100 mΩ max at Tj = 25 °C - limits conduction loss to < 1.15 W at full load |
| Fault Response Time | < 2 µs - enables rapid disconnection during short-circuit to protect downstream wiring and connectors |
| Diagnostic Output | Open-drain FLAG pin - asserts low on overtemperature, overcurrent, or open-load detection for microcontroller monitoring |
| AEC-Q100 Qualification | Grade 1 (−40 °C to +125 °C junction) - validated for under-hood automotive use without derating |
Pinout & Package
Delivered in a thermally enhanced SO-16 narrow-body package with exposed die-pad for improved PCB heat dissipation and mechanical robustness in vibration-prone environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Connects to main 12 V rail; includes internal UVLO and overvoltage clamp |
| GND | Power ground reference | Common return path for load current and internal logic; tied to exposed pad |
| IN | Digital enable input | CMOS-compatible control signal; high = ON, low = OFF with 100 ns propagation delay |
| OUT | High-side switched output | Drives load between OUT and GND; features slew-rate control to limit EMI |
| FLAG | Open-drain fault indicator | Pulled low during thermal shutdown, overcurrent, or open-load detection |
| SENSE | Analog current sense output | Provides proportional voltage (1 V/A) for precise real-time load current monitoring |
Key Features
| Feature | Design Value |
|---|---|
| Embedded thermal shutdown with hysteresis | Triggers at 170 °C junction, releases at 150 °C - prevents latch-up during sustained overload |
| Current-limit accuracy over temperature | ±15% from −40 °C to +150 °C - eliminates need for external calibration in production |
| Load-dump transient immunity | Withstands 40 V/100 ms pulses per ISO 7637-2 Pulse 5a - no external TVS required |
| Diagnostic SENSE pin linearity | 0.95–1.05 V/A across full current range - enables direct ADC sampling without gain compensation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side smart power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INFINEON BTS716G | Lower RDS(on) (70 mΩ), no analog SENSE pin, only digital FLAG output | Lacks real-time current monitoring capability; requires external shunt for closed-loop control | Select when cost sensitivity outweighs need for analog current feedback |
| NXP MC33883 | Higher voltage rating (60 V), slower fault response (> 5 µs), larger HTSSOP-20 package | Better suited for 24 V commercial vehicle systems but less optimal for space-constrained automotive ECUs | Select for dual-voltage (12/24 V) platforms requiring extended surge tolerance |
Compared with BTS716G and MC33883, VND830LSP-E offers the best balance of analog current sensing fidelity, compact SO-16 footprint, and automotive-grade thermal response-making it ideal for next-generation ECU designs where diagnostic richness and board area are critical.

FAQ
What is the maximum safe operating temperature for VND830LSP-E in continuous conduction mode?
The device is rated for junction temperatures up to +150 °C and includes thermal foldback that begins reducing output current above +140 °C. With proper PCB copper pour (≥ 200 mm² per 1 oz Cu on top/bottom layers), it sustains 3.4 A continuously at +105 °C ambient. Derating curves in the official datasheet specify 2.8 A at +125 °C ambient.
Does VND830LSP-E require an external flyback diode when driving inductive loads?
No external flyback diode is required. The IC integrates a clamping diode between OUT and VCC that safely recirculates inductive energy during turn-off. This internal protection meets ISO 7637-2 Pulse 1 requirements for inductive load suppression without additional components.
Can the SENSE pin be used for closed-loop current regulation in real time?
Yes. The SENSE pin delivers a linear 1 V/A analog voltage with ±5% accuracy across the full 0–3.4 A range and −40 °C to +150 °C. It interfaces directly with standard 12-bit microcontroller ADCs, enabling real-time current regulation without signal conditioning or software calibration.
How does the FLAG pin behave during open-load detection?
During open-load (output disconnected), the FLAG pin pulls low after a 100 µs timeout following IN assertion. This behavior is distinct from overcurrent or thermal faults and allows firmware to distinguish between wiring faults and functional failures-critical for automated diagnostic logging in automotive ECUs.
