Product details

Overview

VND830MSP from STMicroelectronics is a dual-channel high-side power switch IC designed for automotive and industrial load driving where one side of the load connects to ground. It delivers 6 A per channel, features 60 mΩ R_DS(on), operates from 5.5 V to 36 V supply, and integrates open-load detection (on/off-state), short-circuit protection, thermal shutdown, reverse battery protection, and ISO 7637-2 transient immunity - used in body control modules for headlight and fog lamp switching.

For engineers reviewing the VND830MSP datasheet, VND830MSP pinout, VND830MSP application, or VND830MSP equivalent, key selection criteria include per-channel current capability, diagnostic status output behavior, undervoltage/overvoltage lockout thresholds, thermal derating under PCB copper constraints, and compatibility with 3.3 V/5 V MCU logic interfaces.

Technical Context

The device implements two independent VIPower™ M0-3 high-side drivers with CMOS-compatible inputs and open-drain status outputs per channel. Each channel includes active current limiting (6–15 A depending on temperature), thermal foldback with hysteresis (TTSD = 150–200 °C, TR = 135 °C), and voltage clamping on VCC to withstand low-energy transients per ISO 7637-2 Pulse 1/2/3a/3b/4/5.

Open-load detection operates in both on-state (I_OL = 0.6–1.2 A) and off-state (V_OL = 1.5–3.5 V), while loss-of-ground protection disables outputs if GND is disconnected. The integrated VCC clamp diode (V_F ≤ 0.6 V at 1.3 A, T_j = 150 °C) enables reverse-battery resilience without external components.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on) per channel	60 mΩ at I_OUT = 0.5 A, T_j = 25 °C - enables <1 W conduction loss at 6 A, reducing heatsink requirements.
Max output current	6 A continuous per channel - sufficient to drive 21 W / 12 V incandescent bulbs as defined load standard.
VCC operating range	5.5 V to 36 V - supports 12 V and 24 V automotive systems including cold-crank (5.5 V) and load-dump (36 V) conditions.
Undervoltage shutdown	4 V typical (3–5.5 V range) - prevents erratic switching during battery brownout or cranking.
Overvoltage shutdown	36 V - protects against ISO 7637-2 Pulse 5a/b load dump surges up to +86.5 V.
Standby supply current	12–40 µA at V_CC = 13 V - minimizes parasitic drain in always-on vehicle domains.
Status output type	Open-drain per channel - allows wired-OR diagnostics and flexible pull-up to 3.3 V or 5 V MCU I/O.

Pinout & Package

Package: PowerSO-10 (exposed die pad, thermally enhanced surface-mount). Pin count: 10 terminals. Mounting requires solderable thermal pad connected to large PCB copper area for R_thj-amb down to 37 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5	OUTPUT1, N.C., OUTPUT2, N.C., GND	Channel 1 and 2 high-side outputs; dedicated GND return path for sensing and protection integrity.
6, 7	INPUT1, STATUS1	CMOS-level enable input and open-drain fault/status indicator for Channel 1.
8, 9	STATUS2, INPUT2	Open-drain fault/status indicator and CMOS-level enable input for Channel 2 (cross-wired order).
10	VCC	Main power supply input with internal clamp diode - must be decoupled near package with ≥10 µF ceramic + bulk capacitor.

Key Features

Feature	Design Value
On/Off-state open-load detection	Enables bulb-out reporting without external sense resistors: detects <0.9 A load (on) or >2.5 V floating output (off).
Integrated reverse battery protection	VCC-to-output clamp diode (V_F ≤ 0.6 V) eliminates need for external series diode in battery feed path.
ISO 7637-2 transient immunity	Withstands Pulse 1 (−100 V), Pulse 2a (+100 V), Pulse 3a/b (±150 V), and Pulse 5a (+86.5 V) without external TVS.
Loss-of-ground protection	Automatic channel disable if GND pin disconnects - prevents uncontrolled load energization during wiring faults.
Thermal foldback with hysteresis	Shuts down at 150–200 °C junction; restarts at 135 °C - avoids thermal runaway during sustained overload.

Applications

Automotive Lighting Control

Industrial Solenoid Driving

Use Scenario: Controlling halogen headlamps and fog lamps in modern body control modules (BCM).

IC Role / Device Role: Dual high-side switch providing independent ON/OFF control and real-time open-bulb diagnostics via STATUS pins.

Use Value: Eliminates need for discrete relays and external current-sense circuitry while meeting OEM EMI and transient immunity requirements (ISO 16750, ISO 7637).

Use Scenario: Driving 24 V DC solenoids in factory automation valves and pneumatic actuators.

IC Role / Device Role: Robust high-side driver with short-circuit and overtemperature protection, enabling safe operation in dusty, high-vibration environments.

Use Value: Reduces system BOM by integrating protection functions that would otherwise require external MOSFETs, sense resistors, and comparators.

Truck & Bus Power Distribution

Off-Highway Equipment Monitoring

Use Scenario: Centralized power switching for auxiliary loads (winches, air horns, work lights) in heavy-duty vehicle ECUs.

IC Role / Device Role: High-current, thermally rugged switch with loss-of-ground detection to prevent unsafe operation after chassis ground corrosion.

Use Value: Supports extended 24 V nominal operation up to 36 V, tolerating alternator overvoltage and battery jump-start transients without latch-up.

Use Scenario: Load management in agricultural and construction machinery control units exposed to wide ambient temperatures (−40 °C to +125 °C).

IC Role / Device Role: Dual-channel protected driver with diagnostic feedback for predictive maintenance of hydraulic valve coils.

Use Value: On-chip open-load detection in off-state identifies broken wires before actuation attempt, reducing false fault alarms and service calls.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN840	Single-channel, integrated current regulation (not open-load detection); no status outputs; lower current (3.5 A).	Targeted at stepper motor phase control, not general-purpose load switching.	Select only when precise current control is required and diagnostics are handled externally.
TPS4H160-Q1	Higher R_DS(on) (100 mΩ), wider VCC range (4–40 V), but lacks off-state open-load detection and reverse-battery diode.	Designed for ASIL-B functional safety compliance with built-in diagnostics; requires external reverse-protection diode.	Prefer when ISO 26262 ASIL-B certification is mandatory and board space allows added protection components.

Compared with VND830MSP, STSPIN840 trades diagnostics for precision current regulation and reduced channel count, while TPS4H160-Q1 adds functional safety features at the cost of higher conduction loss and external protection overhead - making VND830MSP optimal for cost-sensitive, non-ASIL automotive lighting where integrated diagnostics and reverse-battery resilience are critical.

FAQ

What is the maximum junction temperature and thermal shutdown behavior?

The VND830MSP triggers thermal shutdown between 150 °C and 200 °C (typical 175 °C), with automatic restart at 135 °C. Thermal hysteresis ensures stable cycling during overload, and R_thj-amb drops to 37 °C/W with 6 cm² of 35 µm copper - critical for sustaining 6 A per channel in enclosed enclosures.

How does off-state open-load detection work, and what external components are needed?

Off-state detection monitors output voltage: if V_OUT rises above 1.5–3.5 V (e.g., due to leakage or broken wire), STATUS goes low after ~1 ms delay. No external components are required - the function uses internal current sources and comparators. An external pull-up resistor (typically 10 kΩ to V_CC) is needed on each STATUS pin for proper logic level translation.

Can VND830MSP drive inductive loads like fuel injectors or relays?

Yes - it supports inductive loads with demagnetization energy handling up to 100 mJ (L = 1.8 mH, V_BAT = 13.5 V, I_L = 9 A). The internal V_CC-to-output clamp limits turn-off voltage spikes to V_CC − 41 V, eliminating need for external flyback diodes in most 12 V applications.

Is VND830MSP still in active production, and what packaging options are offered?

VND830MSP is an obsolete part per ST's official documentation (Doc ID 7379 Rev 5), but Aetrix Electronics maintains legacy inventory in both tube (VND830MSP) and tape-and-reel (VND830MSP13TR) formats. Full traceability, RoHS-compliant ECOPACK® PowerSO-10 packaging, and full datasheet compliance are guaranteed for remaining stock.
