Product details
Overview
VN750SMPTR-E from STMicroelectronics is a high-side power switch IC designed for automotive load driving with one side grounded. It delivers 6 A continuous output current, features 55 mΩ RDS(on) at 25°C, operates up to 36 V supply, and integrates on/off-state open-load detection, short-circuit protection, reverse-battery tolerance, and thermal shutdown. It is used in body control modules for driving lamps, solenoids, and relays.
For engineers reviewing the VN750SMPTR-E datasheet, VN750SMPTR-E pinout, VN750SMPTR-E application, or VN750SMPTR-E equivalent, key selection criteria include its AEC-Q100 qualification, SO-8 package thermal performance, diagnostic status pin behavior, and ISO 7637-2 transient immunity in automotive 12 V systems.
Technical Context
This device implements a monolithic VIPower™ M0-3 high-side driver architecture with active VCC clamping for low-energy transient suppression (ISO 7637-2 Pulse 1/2a/3a/3b compliant), integrated current limiting (6–12 A range), and thermal foldback with automatic restart. Its logic-compatible input accepts CMOS-level signals and provides hysteresis (0.5 V) for noise immunity.
The status pin outputs an open-drain signal indicating fault conditions including overtemperature (>150°C), undervoltage (<4 V), overvoltage (>36 V), output short-to-VCC, and open-load states-both during conduction (IOL = 0.9 A typ.) and turn-off (VOL = 2.5 V typ.). Protection logic is fully hardware-based with no microcontroller dependency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 55 mΩ max at IOUT = 2 A, Tj = 25°C - enables low conduction loss and <1 W dissipation at 6 A in typical PCB layout |
| Continuous Output Current | 6 A - supports automotive incandescent bulbs (e.g., 5W/12V), solenoids, and small motors without external heatsinking |
| VCC Operating Range | 5.5 V to 36 V - covers cold-crank (5.5 V) to load-dump (36 V) conditions in 12 V vehicle systems |
| Open-Load Detection Threshold (On-State) | 0.9 A typ. - reliably identifies disconnection of standard 12 V/5 W filament lamps during activation |
| Status Pin Logic | Open-drain, clamp-limited to 6.8 V - interfaces directly with 3.3 V or 5 V MCU GPIOs without level-shifting |
| Thermal Shutdown Threshold | 150°C ±25°C - triggers automatic current foldback and status flag assertion before silicon damage occurs |
| Reverse Battery Tolerance | -14 V sustained - survives reversed battery connection via internal GND protection network (per Figure 24) |
Pinout & Package
Package: SO-8 (Small Outline, 150 mil width), RoHS-compliant, ECOPACK® lead-free finish. Thermal resistance Rthj-amb = 93 °C/W (0.5 cm² copper) or 82 °C/W (2 cm² copper) per datasheet Table 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INPUT) | CMOS-compatible control input | Accepts 3.25 V high / 1.25 V low; 0.5 V hysteresis prevents chatter near threshold |
| 2 (GND) | Power ground reference | Must be connected to chassis ground; disconnect triggers immediate shutdown (loss-of-ground protection) |
| 3 (OUTPUT) | High-side switched output | Drives load between this pin and ground; includes active clamp during inductive turn-off |
| 4 (STATUS) | Fault diagnostic output | Open-drain; pulled low during undervoltage, overvoltage, overtemperature, open-load, or short-circuit |
| 5 (VCC) | Supply input with active clamp | Internally clamped to ~41 V; withstands ISO 7637-2 Pulse 5a (86.5 V, 400 ms) with external TVS |
| 6 (GND) | Second ground terminal | Reduces ground path impedance; must be tied to same node as Pin 2 for AEC-Q100 compliance |
| 7 (OUTPUT) | Redundant output terminal | Parallel-connected to Pin 3 to reduce bond-wire resistance and improve current sharing |
| 8 (VCC) | Redundant supply terminal | Parallel-connected to Pin 5 to minimize supply path inductance and enhance transient immunity |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Grade Qualification | AEC-Q100 Grade 1 (−40°C to +125°C ambient), validated for 15-year vehicle life |
| Diagnostic Status Pin | Differentiates fault types via timing and state persistence - e.g., open-load off-state delay = 1000 µs, on-state = 200 µs |
| Short-Circuit Protection | Current-limited to 6–12 A depending on junction temperature; automatically recovers after fault removal |
| Loss-of-Ground Detection | Shuts down within microseconds if GND pins are disconnected - prevents uncontrolled load activation |
| Low Standby Current | ≤10 µA at VCC = 13 V, Tj = 25°C - meets automotive "off-mode" leakage requirements |
Applications
| Headlamp Control | Engine Cooling Fan Drive |
|---|---|
|
Use Scenario: Switching 12 V halogen headlamps in modern body control modules with real-time fault monitoring. IC Role / Device Role / Timing Role: High-side switch providing controlled lamp turn-on/turn-off with soft-slope dV/dt (400–1000 V/ms) to limit EMI. Use Value: On-state open-load detection confirms bulb integrity before ignition; status pin alerts MCU to filament breakage during operation. |
Use Scenario: Driving brushed DC cooling fans in engine bays where temperature, vibration, and voltage transients are severe. IC Role / Device Role / Timing Role: Robust power interface with thermal foldback and ISO 7637-2 Pulse 5a immunity ensures fan remains operational during load dump events. Use Value: Reverse-battery protection prevents latch-up during service; short-circuit current limiting avoids fuse blowing during stalled-fan faults. |
| Door Lock Actuator Interface | Heated Rear Window Control |
|
Use Scenario: Controlling solenoid-based door lock actuators requiring precise pulse-width modulation and stall detection. IC Role / Device Role / Timing Role: High-side driver with fast turn-on delay (40 µs typ.) and accurate current sensing for PWM duty-cycle optimization. Use Value: Off-state open-load detection verifies actuator coil continuity before each lock/unlock cycle; status pin flags coil open or short. |
Use Scenario: Managing high-current heated rear window circuits subject to condensation-induced leakage and intermittent shorts. IC Role / Device Role / Timing Role: Fault-tolerant switch with dual VCC/GND pins minimizing PCB trace inductance and improving EMC robustness. Use Value: Undervoltage lockout prevents partial heating during cranking; overvoltage shutdown protects against alternator regulation failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS27081AQPWPRQ1 | Lower RDS(on) (25 mΩ), but only 3.6 A rated; no off-state open-load detection; requires external status conditioning | Better for space-constrained 3.3 V MCU systems; lacks integrated diagnostics for lamp monitoring | Select when thermal budget is tighter and diagnostic depth is secondary to conduction loss |
| IPS1025H | Higher current rating (10 A), wider VCC range (4.5–60 V), but larger HTSSOP-16 package and higher quiescent current (35 µA) | Suitable for 24 V commercial vehicles and industrial controls; less optimized for compact 12 V BCM layouts | Choose for multi-voltage platforms or where higher surge current capability is required |
Compared with VN750SMPTR-E, the TPS27081AQPWPRQ1 trades diagnostic completeness for lower on-resistance and smaller footprint, while the IPS1025H extends voltage and current range at the cost of board area and standby power - making VN750SMPTR-E optimal for cost-sensitive, diagnostic-rich 12 V automotive body electronics.

FAQ
What is the maximum inductive load energy the VN750SMPTR-E can safely demagnetize?
The device supports up to 90 mJ maximum switching energy (EMAX) under specified test conditions: L = 1.3 mH, RL = 0 Ω, Vbat = 13.5 V, Tjstart = 150°C, IL = 10 A. This value is validated per datasheet Section 2.2 and defines the upper bound for safe turn-off of inductive loads like fuel injectors or solenoids without external snubbers.
How does the VN750SMPTR-E detect open-load in the off-state?
It applies a weak internal current source to the OUTPUT pin while INPUT is low, then measures resulting voltage. If VOUT exceeds 2.5 V (typ.), the load is classified as open. Detection delay is 1000 µs, and the condition asserts the STATUS pin low - enabling MCU-based verification of load integrity before next activation cycle.
Can the VN750SMPTR-E drive a 24 V load?
No - its absolute maximum VCC rating is 41 V, but its guaranteed operating range is 5.5 V to 36 V. While it may survive brief 24 V transients, sustained 24 V operation exceeds its design envelope and risks undervoltage lockout (VUSD = 4 V min) or premature thermal shutdown due to increased RDS(on) at elevated voltage.
Is external pull-up required on the STATUS pin?
Yes - the STATUS pin is open-drain and requires an external pull-up resistor (typically 4.7 kΩ to VCC or MCU I/O rail) to generate a valid high-level signal during normal operation. Without it, the pin floats and cannot indicate "no fault" reliably; datasheet Figure 4 shows this configuration explicitly.
