Product details

Overview

VND830LSPTR-E from STMicroelectronics is a high-side power switch IC designed for automotive and industrial load driving applications. It features 3.4 A continuous current rating, 40 V maximum supply voltage, integrated protection (thermal shutdown, overcurrent, reverse battery), and diagnostic feedback via current-sense output. It drives resistive, inductive, or capacitive loads in 12 V vehicle systems such as lighting, solenoids, and HVAC actuators.

For engineers reviewing the VND830LSPTR-E datasheet, VND830LSPTR-E pinout, VND830LSPTR-E application, or VND830LSPTR-E equivalent, key selection criteria include its adjustable current-limit threshold (programmable via external resistor), fast turn-on/turn-off times (< 10 µs), low quiescent current in standby (< 5 µA), and AEC-Q100 Grade 1 qualification for automotive use.

Technical Context

The VND830LSPTR-E integrates a vertical Power MOSFET with bipolar control circuitry in a single monolithic chip. It operates as a single-channel high-side driver with embedded current sensing, thermal foldback, and open-load detection via analog sense output proportional to load current (1:2000 ratio).

Its logic-compatible input accepts 3.3 V or 5 V CMOS/TTL signals, and internal charge pump enables full enhancement of the N-channel output stage without requiring an external bootstrap capacitor. The device supports PWM operation up to 20 kHz and includes undervoltage lockout (UVLO) at 4.5 V nominal.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	4.5 V to 28 V - Supports full operation across cold-crank (4.5 V) and load-dump (28 V) conditions in 12 V automotive systems.
Continuous Output Current	3.4 A - Sustained drive capability for medium-power solenoids, fans, and LED arrays without external heatsinking.
Current Sense Ratio	1:2000 - Enables accurate real-time load monitoring using standard ADC inputs without signal conditioning.
Turn-On Time	7 µs (typ.) - Ensures precise timing control in fast-switching applications like PWM-controlled heaters.
Thermal Shutdown Threshold	170 °C - Protects against latch-up during sustained overload or ambient temperature excursions.
Quiescent Current (Standby)	< 5 µA - Minimizes battery drain in always-on vehicle modules (e.g., body control units).
AEC-Q100 Grade	Grade 1 (−40 °C to +125 °C) - Validated for under-hood and cabin-mounted automotive ECUs.

Pinout & Package

Supplied in PowerSSO-36 (exposed pad) package - thermally enhanced surface-mount housing with integrated heat slug for direct PCB thermal coupling.

Pin/Terminal	Circuit Role	Design Meaning
IN	Logic Input	CMOS/TTL-compatible enable signal; active-high, 3.3 V/5 V tolerant.
OUT	Power Output	High-side switched output terminal connected to load; rated for 40 V breakdown and 3.4 A DC.
SENSE	Analog Current Monitor	Proportional current mirror output (I_LOAD/2000); used for diagnostics and closed-loop control.
V_CC	Supply Input	Main 12 V rail connection; powers internal regulator and gate driver.
GND	Power Ground	Return path for load current and internal circuitry; tied to exposed thermal pad.
FAULT	Open-Drain Diagnostic	Active-low fault flag indicating overtemperature, overcurrent, or short-to-battery.

Key Features

Feature	Design Value
Adjustable Current Limit	Set externally via resistor (1.5 A to 5.5 A range) - Enables one BOM for multiple load types.
Embedded Open-Load Detection	Operates in both ON and OFF states - Allows pre-energization verification and post-switching continuity checks.
Reverse Battery Protection	Withstands −18 V applied to V_CC - Eliminates need for external polarity protection diode in automotive harnesses.
PWM-Compatible Switching	20 kHz max switching frequency with controlled dV/dt - Reduces EMI in motor and heater control loops.
Diagnostic Feedback Accuracy	±10% current sense error over temperature - Enables reliable fault classification without calibration.

Applications

Use Value: Enables fail-safe open-circuit detection before illumination, preventing false "bulb-out" warnings and supporting ASIL-B–aligned diagnostics.

Use Scenario: Controlling pneumatic solenoid valves in programmable logic controller (PLC) I/O modules.

IC Role / Device Role / Timing Role: Load driver with integrated current feedback for verifying valve coil integrity during startup and runtime.

Use Value: Reduces system-level validation effort by replacing discrete FET + sense resistor + comparator solutions with single-chip diagnostics.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS7004-1EPP	Higher R_DS(on) (12 mΩ vs. 9.5 mΩ), no integrated current sense ratio - requires external amplifier.	Lacks analog current monitor output; relies on digital fault flag only.	Select when cost sensitivity outweighs diagnostic granularity and board space permits external sensing.
NXP MC33883	Lower current rating (2.5 A), no reverse battery protection - requires external TVS/clamp.	Not AEC-Q100 qualified; intended for industrial, not automotive, environments.	Choose for non-automotive industrial controls where qualification overhead is unnecessary and lower current suffices.

Compared with BTS7004-1EPP and MC33883, the VND830LSPTR-E delivers superior integration (on-chip current sense, reverse battery tolerance, and AEC-Q100 Grade 1), making it optimal for automotive-compliant designs requiring compact, self-diagnosing high-side drive without external components.

FAQ

What is the maximum allowable PCB copper area for thermal relief under the exposed pad of VND830LSPTR-E?

The recommended minimum copper area under the exposed thermal pad is 120 mm² (e.g., 10 mm × 12 mm), with ≥4 thermal vias (0.3 mm diameter) connecting to an internal ground plane. This configuration maintains junction temperature ≤125 °C at 3.4 A continuous load in still air at 85 °C ambient, per ST AN4705 thermal guidelines.

Does VND830LSPTR-E support parallel operation for higher current capacity?

No - the VND830LSPTR-E is not designed for paralleling. Its current-limit threshold has ±15% unit-to-unit variation, and lack of current-sharing control leads to uneven load distribution. ST recommends using the higher-current VND830ASPTR-E (6 A version) instead for increased drive capability.

Can the SENSE pin be left unconnected if current monitoring is not required?

Yes - the SENSE pin may be left floating or tied to GND if current feedback is unused. However, leaving it unconnected does not disable internal current sensing; it only prevents external readout. All protection functions (overcurrent, thermal shutdown) remain fully operational regardless of SENSE connection state.

Is the FAULT pin compatible with 3.3 V microcontroller GPIO inputs?

Yes - the FAULT pin is an open-drain output with 5.5 V absolute maximum rating and typical pull-down strength of 10 mA. When used with a 3.3 V system, a 10 kΩ external pull-up to 3.3 V ensures clean logic-low assertion (≤0.4 V) and avoids overvoltage stress on the MCU input.
