Product details

Overview

VN750(012Y) from STMicroelectronics is a monolithic high-side power switch fabricated in VIPower® M0-3 technology, designed to drive grounded loads in automotive and industrial control systems. It features 60 mΩ R_DS(on), 6 A continuous output current, 36 V supply voltage rating, CMOS-compatible input, and integrated on/off-state open-load detection. Used in body electronics for lamp and solenoid control where ground-referenced loads require robust protection.

For engineers reviewing the VN750(012Y) datasheet, VN750(012Y) pinout, VN750(012Y) application, or VN750(012Y) equivalent, key selection criteria include its active current limiting (6–15 A), thermal shutdown with 150°C trip point, reverse battery protection, and dual-mode open-load diagnostics - all critical for reliable 12 V/24 V automotive load management.

Technical Context

The VN750(012Y) integrates a vertical power MOSFET with embedded logic, protection circuitry, and diagnostic feedback via a dedicated STATUS pin. Its VIPower® M0-3 process enables precise current limitation (6–15 A depending on V_CC), thermal shutdown with 15°C hysteresis, and undervoltage (4 V) / overvoltage (36 V) lockout.

It implements two independent open-load detection modes: during ON-state (threshold 50–200 mA), and OFF-state (detects output shorted to V_CC when V_OUT > 1.5 V). The STATUS pin provides open-drain fault signaling with clamp protection (−0.7 V to 8 V) and leakage <10 µA.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	60 mΩ typical at I_OUT = 2 A, T_j = 25°C - enables low conduction loss and minimal self-heating under full load
I_OUT Continuous	6 A - supports automotive lamps, valves, and small motors without external heatsinking on standard PCB copper
V_CC Range	5.5 V to 36 V - compatible with 12 V and 24 V vehicle electrical systems including cold-crank and load-dump transients
Open-load Detection	Active in both ON-state (50–200 mA threshold) and OFF-state (V_OUT > 1.5 V) - enables real-time wiring integrity monitoring without added components
Thermal Shutdown	Triggers at 150°C junction temperature with 15°C hysteresis - prevents permanent damage during sustained overload or poor thermal design
Reverse Battery Protection	Withstand −0.3 V V_CC and −200 mA reverse ground current - eliminates need for external series diode in battery-reversed scenarios
STATUS Pin Output	Open-drain, clamped −0.7 V to 8 V, leakage <10 µA - directly interfaces with 3.3 V/5 V MCU GPIO for fault reporting with minimal external circuitry

Pinout & Package

VN750(012Y) is supplied in SO-8 package (ECOPACK® compliant), with exposed pad for thermal enhancement. Pin 1 is INPUT, Pin 2 is GND, Pin 3 is STATUS, Pin 4 is V_CC, Pin 5 is OUTPUT, Pins 6–8 are internally connected to OUTPUT and GND for current handling and thermal dissipation.

Pin/Terminal	Circuit Role	Design Meaning
INPUT (Pin 1)	CMOS-compatible digital control input	Accepts 3.25 V high / 1.25 V low logic; 1 µA max input current enables direct MCU interface without level-shifting
GND (Pin 2)	Power and signal reference ground	Shared return path for load current and logic; protected against reverse battery (−200 mA rating)
STATUS (Pin 3)	Diagnostic open-drain fault output	Pulls low on undervoltage, overtemperature, overcurrent, or open-load faults; requires external pull-up resistor
V_CC (Pin 4)	Main power supply input	Clamped to 41 V internally; withstands ISO 7637-2 pulse 5a (load dump) up to 40 V with external TVS
OUTPUT (Pin 5)	High-side switched output terminal	Drives load between this pin and system ground; rated for 6 A continuous, handles inductive turn-off energy up to 100 mJ (SO-8)
Pins 6–8	Internally bonded OUTPUT/GND	Enhance current carrying capacity and thermal conduction to PCB copper; must be soldered to matching copper pour

Key Features

Feature	Design Value
On/Off-state open-load detection	Enables end-to-end wiring diagnostics without external sense resistors or ADC sampling - reduces BOM and firmware overhead
Active current limitation (6–15 A)	Prevents destructive latch-up during short circuits while maintaining controlled output voltage drop - simplifies fuse selection and system-level fault response
Integrated reverse battery protection	Eliminates need for external series diode or MOSFET in battery-connected applications - saves board space and forward voltage drop
V_CC pin voltage clamp	Protects internal circuitry against low-energy transients (e.g., ISO 7637-2 pulse 1/2a) without requiring external clamping components
Very low standby current (≤25 µA)	Meets automotive quiescent current requirements for always-on modules - avoids battery drain in parked vehicle conditions

Applications

IC Role / Device Role / Timing Role: Robust output driver with built-in short-circuit and thermal protection, interfaced to microcontroller via isolated digital input.

Use Value: Reduces system-level validation effort by integrating protection functions that would otherwise require discrete ICs and layout-intensive current paths.

Commercial Vehicle Lighting System

Off-Highway Equipment Power Distribution

Use Scenario: Managing headlamp, fog lamp, and marker light loads in trucks and buses operating across −40°C to +125°C ambient.

IC Role / Device Role / Timing Role: High-side driver with extended V_CC range (5.5–36 V) and load-dump tolerant V_CC clamp.

Use Value: Maintains operation during cold-crank (5.5 V) and load dump (up to 40 V) events without external protection - improves system uptime.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN7012AJR	Lower R_DS(on) (30 mΩ), higher I_OUT (10 A), same SO-8 package but no off-state open-load detection	Lacks OFF-state short-to-V_CC detection - unsuitable where wiring integrity must be verified with load de-energized	Select when higher current and lower conduction loss are prioritized over comprehensive diagnostics
INFINEON BTS716G	Higher R_DS(on) (100 mΩ), includes SPI interface and enhanced diagnostics (e.g., current sense analog output)	Requires SPI host controller and additional firmware; not pin-compatible - demands PCB and software redesign	Select when system-level diagnostics (e.g., real-time current measurement) justify added complexity and cost

Compared with VN750(012Y), STVN7012AJR trades diagnostic completeness for higher drive capability, while BTS716G adds programmability at the cost of integration simplicity and pin compatibility - making VN750(012Y) optimal for cost-sensitive, diagnosis-critical 6 A automotive switches.

FAQ

What is the maximum inductive load energy the VN750(012Y) can safely interrupt in SO-8 package?

The VN750(012Y) in SO-8 package supports up to 100 mJ of demagnetization energy (L = 1.8 mH, V_BAT = 13.5 V, I_L = 9 A, T_j,start = 150°C), as specified in Table 4 of the datasheet. This value assumes proper PCB copper area (0.5 cm²) and natural convection cooling. Exceeding this risks thermal runaway during turn-off.

Does the VN750(012Y) require an external pull-up resistor on the STATUS pin?

Yes - the STATUS pin is an open-drain output and requires an external pull-up resistor (typically 4.7 kΩ to V_CC or MCU I/O rail) to generate a valid logic-high signal during normal operation. Without it, the pin remains floating and cannot indicate fault-free status reliably.

Can the VN750(012Y) be used in 24 V truck applications with load dump transients?

Yes - the V_CC pin has an internal clamp and is rated for 41 V absolute maximum. When combined with an external 36 V TVS diode (e.g., SMAJ36A), it meets ISO 7637-2 Pulse 5a (load dump) requirements for 24 V systems. Layout must minimize V_CC trace inductance to ensure effective clamping.

How does the VN750(012Y) detect open-load in the OFF state?

When INPUT = LOW, the device monitors V_OUT through an internal comparator. If V_OUT rises above 1.5–3.5 V (e.g., due to leakage or accidental short to V_CC), the STATUS pin asserts LOW after ≤1000 µs delay. This confirms wiring integrity even when the load is de-energized - critical for safety-critical diagnostics.
