Product details

Overview

VN750-12-E from STMicroelectronics is a high-side power switch IC designed for driving grounded loads in automotive and industrial control systems. It features 60 mΩ R_DS(on), 6 A continuous output current, 36 V maximum supply voltage, CMOS-compatible input, and integrated open-load detection in both on- and off-states. It is used in body electronics such as lamp drivers and solenoid controls where robust fault diagnostics and reverse-battery protection are required.

For engineers reviewing the VN750-12-E datasheet, VN750-12-E pinout, VN750-12-E application, or VN750-12-E equivalent, key selection criteria include its active current limitation (6–15 A), thermal shutdown with 150°C trip point, undervoltage/overvoltage shutdown thresholds (4 V / 36 V), and status pin diagnostic capability for real-time load monitoring.

Technical Context

The VN750-12-E implements VIPower® M0-3 technology to integrate high-voltage DMOS output stage, logic driver, protection circuitry, and diagnostic feedback in a single monolithic die. Its architecture supports ground-referenced load switching with active VCC clamp for low-energy spike suppression and automatic restart after thermal shutdown.

It provides dual-mode open-load detection: during ON-state via current threshold sensing (50–200 mA), and OFF-state via output voltage threshold (1.5–3.5 V) when output is shorted to VCC. Protection functions-including loss-of-ground detection, short-circuit current limiting, and reverse-battery protection-are hardware-automated without MCU intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	60 mΩ typical at 2 A, 25°C - enables low conduction loss and minimal self-heating in 12 V automotive systems
I_OUT Continuous	6 A - supports medium-power actuators like fuel injectors, HVAC valves, and LED arrays
V_CC Range	5.5–36 V - covers full automotive battery range including cold-crank (5.5 V) and load-dump transients (up to 36 V)
Undervoltage Shutdown	4 V ±0.5 V - prevents erratic operation during battery brownout while allowing startup at marginal voltages
Overvoltage Shutdown	36 V - clamps operation before damage occurs during ISO 7637-2 pulse 5a transients
Status Pin Output	Open-drain, 0.5 V max at 1.6 mA - provides direct MCU-readable fault indication (open-load, overtemp, overload)
Thermal Shutdown Trip	150°C junction temperature - protects against sustained overload while permitting brief peak-current operation

Pinout & Package

The VN750-12-E is housed in a PENTAWATT (5-pin, through-hole) package with exposed tab for thermal dissipation. The package meets ECOPACK® environmental compliance and supports PCB mounting with ≥0.5 cm² copper area for optimal thermal performance (R_thj-amb = 62.1°C/W).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Power supply input	Clamped to 41 V absolute max; supplies internal logic and gate drive; connects to battery rail
GND	Ground reference	Return path for load current and internal circuitry; loss-of-ground triggers automatic shutdown
INPUT	Digital control input	CMOS-compatible (1.25 V low / 3.25 V high); 1 µA leakage enables direct MCU GPIO interface
OUTPUT	High-side switched output	Drives one side of load; other side grounded; supports inductive demagnetization up to 138 mJ
STATUS	Fault diagnostic output	Open-drain signal indicating open-load (ON/OFF), overtemperature, overcurrent, or VCC fault

Key Features

Feature	Design Value
On-state open-load detection	Triggers at 50–200 mA load current absence; enables immediate lamp/solenoid failure reporting
Off-state open-load detection	Identifies output short-to-VCC condition (e.g., wiring fault) with 1.5–3.5 V threshold
Shorted-load protection	Active current limit (6–15 A) + thermal shutdown + auto-restart prevents latch-up during sustained shorts
Reverse battery protection	Integrated GND protection network eliminates need for external series diode or MOSFET
Very low standby current	10–25 µA at 13 V - critical for always-on vehicle modules meeting ISO 16750 quiescent current limits

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VN750S	SO-8 surface-mount package; identical electrical specs but lower thermal resistance (R_thj-amb = 93°C/W vs 62.1°C/W)	Better suited for space-constrained PCBs; requires more careful thermal layout due to higher junction-to-ambient resistance	Select when board area is limited and ambient temperature remains below 85°C
VN750-B5	P2PAK package; same R_DS(on) and protection features; higher power dissipation (60 W vs 60 W) and lower R_thj-case (2.1°C/W)	Optimized for high-temperature under-hood environments; supports higher continuous current in thermally demanding enclosures	Select for under-hood applications requiring >100,000-hour lifetime at 125°C case temperature

Compared with VN750S and VN750-B5, the VN750-12-E (PENTAWATT) offers superior mechanical robustness for vibration-prone automotive harness connections, easier manual soldering in low-volume assembly, and proven reliability in legacy body-control modules-making it the preferred choice for service replacement and retrofit designs.

FAQ

What is the function of the STATUS pin on VN750-12-E?

The STATUS pin is an open-drain diagnostic output that signals faults including open-load (both on- and off-state), overtemperature, overcurrent, and VCC undervoltage/overvoltage conditions. It pulls low when any fault is detected and remains high-impedance otherwise, enabling direct connection to a microcontroller's interrupt-capable GPIO with a single pull-up resistor.

Does VN750-12-E require an external flyback diode for inductive loads?

No. The VN750-12-E integrates an internal clamp diode between OUTPUT and VCC, enabling safe demagnetization of inductive loads up to 138 mJ (at VCC = 13.5 V). This eliminates the need for an external freewheeling diode in most automotive solenoid and relay applications.

Can VN750-12-E operate with a 5 V logic supply while powered from 24 V VCC?

Yes. The INPUT pin is CMOS-compatible with logic thresholds of 1.25 V (low) and 3.25 V (high), and draws only 1 µA at 1.25 V. It interfaces directly with 3.3 V or 5 V MCUs without level-shifting, even when VCC is at 24 V - verified across -40°C to 150°C junction temperature range.

How does VN750-12-E handle reverse battery connection?

VN750-12-E incorporates a dedicated GND protection network that detects reverse polarity and disables the output stage before damage occurs. Unlike solutions requiring external series diodes, this internal architecture maintains full 6 A drive capability and avoids forward voltage drop penalties in normal operation.
