Product details

Overview

VN750SM-E from STMicroelectronics is a high-side power switch IC designed for automotive and industrial load driving with one side grounded. It features 55 mΩ R_DS(on), 6 A continuous output current, 36 V max supply voltage, CMOS-compatible input, and integrated open-load detection in both on/off states. It drives resistive, inductive, or capacitive loads in 12 V vehicle systems such as lighting, solenoids, and HVAC actuators.

For engineers reviewing the VN750SM-E datasheet, VN750SM-E pinout, VN750SM-E application, or VN750SM-E equivalent, this page delivers verified electrical parameters, SO-8 package layout, protection behavior under undervoltage/overvoltage/overtemperature conditions, and real-world diagnostic timing (e.g., 200 µs open-load detection delay in on state).

Technical Context

The VN750SM-E integrates VIPower M0-3 technology to combine vertical power MOSFET switching with smart logic and diagnostics. Its internal current limiter (6–12 A) works in tandem with thermal shutdown (T_j = 150 °C) and automatic restart, while status pin reporting enables real-time fault classification-distinguishing open-load (V_OL = 1.5–3.5 V), overtemperature (T_SD = 150–200 °C), and overvoltage (V_OV = 36 V) events.

It supports ISO 7637-2 transient immunity up to Level IV (±100 V pulses), includes reverse battery protection via external ground network design, and uses active V_CC clamping to suppress low-energy spikes. The device operates across -40 °C to +150 °C junction temperature and maintains <10 µA standby current at 13 V.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	55 mΩ typical at I_OUT = 2 A, T_j = 25 °C - ensures ≤0.22 W conduction loss at 2 A, enabling compact thermal design
I_OUT Continuous	6 A - supports automotive bulbs (e.g., 5W/12V filament) and small solenoids without external heatsinking
V_CC Range	5.5 V to 36 V - covers full automotive battery range including cold-crank (5.5 V) and load-dump (36 V)
Open-Load Detection	On-state threshold: 0.6–1.2 A; Off-state threshold: V_OL = 1.5–3.5 V - reliably identifies disconnected 12 V lamps or broken wiring
Turn-on/Off Delay	t_d(on) = 40 µs, t_d(off) = 30 µs - enables fast PWM control for dimming or duty-cycle modulation
Status Pin Logic	V_STAT(L) ≤ 0.5 V at I_STAT = 1.6 mA - provides TTL-compatible fault signaling to microcontroller GPIO
Thermal Shutdown	T_TSD = 150–200 °C with 7–15 °C hysteresis - prevents permanent damage during sustained overload

Pinout & Package

Delivered in SO-8 package (5.0 mm × 6.2 mm × 1.75 mm), with exposed thermal pad connected internally to V_CC pins (pins 4 and 5) for enhanced heat dissipation. Standard JEDEC MS-012AC footprint, compatible with automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
1 (INPUT)	Digital control input	CMOS-compatible (V_IL ≤ 1.25 V, V_IH ≥ 3.25 V); 0.5 V hysteresis prevents noise-induced toggling
2 (GND)	Power ground reference	Must be connected to system ground; disconnection triggers automatic shutdown
3 (STATUS)	Fault reporting output	Open-drain output with internal pull-down; requires external pull-up to report open-load, overtemp, or overvoltage
4,5 (V_CC)	Positive supply input	Dual V_CC pins reduce IR drop and improve transient immunity; clamp diode protects against ISO 7637 pulses
6 (OUTPUT)	High-side switched output	Drives load between OUTPUT and GND; handles inductive kickback via demag clamp (V_demag = V_CC − 41 V)
7 (N.C.)	No connection	Internally unconnected; must remain floating per datasheet recommendation
8 (N.C.)	No connection	Internally unconnected; must remain floating per datasheet recommendation

Key Features

Feature	Design Value
Active V_CC clamp	Suppresses ISO 7637 Pulse 2a (+50 V/0.2 ms) and Pulse 1 (−50 V/2 ms) without external TVS
On/off state open-load detection	Identifies open filament in headlight (5W/12V) during operation or key-off, eliminating need for separate sense circuitry
Reverse battery protection support	Enables robust ground-network design using either series resistor (R_GND) or diode (D_GND) to prevent latch-up
Low quiescent current	≤10 µA at V_CC = 13 V, T_j = 25 °C - meets automotive standby current requirements for always-on modules
Integrated thermal shutdown with hysteresis	Auto-restart after cooling below T_R = 135 °C prevents thermal runaway during intermittent overload

IC Role / Device Role / Timing Role: High-side switch with real-time open-load diagnosis during ignition-on and key-off states.

Use Value: Eliminates need for external current-sense resistors and reduces BOM count by integrating fault detection and protection.

Use Scenario: Controlling pneumatic valves and fuel injectors in engine management systems.

IC Role / Device Role / Timing Role: Inductive load driver with demagnetization clamp and short-to-V_CC detection during de-energization.

Use Value: Prevents MOSFET failure from back-EMF and enables safe PWM actuation without snubber networks.

HVAC Blower Motor Interface

Truck Trailer Connector Monitoring

Use Scenario: Switching DC blower motors in commercial vehicle climate control units.

IC Role / Device Role / Timing Role: High-current (6 A) load switch with thermal foldback and status feedback to MCU.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Lower R_DS(on) (30 mΩ), but rated only for 3.5 A continuous; no off-state open-load detection	Suitable for lower-power motor drivers where thermal margin is critical, but lacks diagnostic capability for lamp monitoring	Select when peak efficiency > fault visibility, and load current stays below 3.5 A
VN7050AJ	Same SO-8 package, higher current rating (14 A), but requires external status pull-up and has slower t_d(off) (100 µs)	Better for high-current solenoids; less suitable for fast PWM lighting control due to longer turn-off delay	Select when driving >6 A inductive loads and diagnostic speed is secondary to current capacity

Compared with VN750SM-E, STSPIN250 trades diagnostic completeness for lower conduction loss, while VN7050AJ extends current capability at the cost of timing responsiveness and integrated off-state fault detection.

FAQ

What is the maximum inductive load energy the VN750SM-E can safely demagnetize?

The VN750SM-E supports up to 90 mJ of switching energy (E_MAX) with L = 1.3 mH, R_L = 0 Ω, V_bat = 13.5 V, and T_j,start = 150 °C. This corresponds to safe turn-off of typical 12 V automotive solenoids and relays without external flyback diodes, provided PCB copper area meets thermal resistance targets (R_thj-amb ≤ 93 °C/W).

How does the VN750SM-E detect open-load in the off state?

Off-state open-load detection requires an external pull-up resistor (R_PU) between OUTPUT and V_PU (e.g., +5 V). When the load is disconnected, leakage current (I_L(off2) ≤ 0 µA) pulls OUTPUT above V_OL = 1.5–3.5 V, triggering STATUS assertion. The datasheet specifies R_PU < (V_PU − V_OLmax)/I_L(off2) to ensure reliable detection without false positives.

Can the VN750SM-E operate with a 5 V microcontroller logic interface?

Yes - its INPUT pin accepts CMOS-compatible levels: V_IL ≤ 1.25 V (low) and V_IH ≥ 3.25 V (high), with 0.5 V hysteresis. A 5 V MCU GPIO directly drives INPUT without level-shifting. STATUS is open-drain and requires a 4.7 kΩ pull-up to 5 V for TTL-compatible fault signaling to the same MCU.

Is reverse battery protection built-in or external?

Reverse battery protection is not fully integrated - it requires external implementation per Figure 8. Two validated methods exist: (1) a series resistor (R_GND) sized to limit reverse current below −200 mA, or (2) a Schottky diode (D_GND) in the ground path with parallel 1 kΩ resistor for inductive loads. Both methods prevent latch-up and enable safe operation down to −14 V.
