Product details
Overview
VNQ7140AJTR-E from STMicroelectronics is a quad-channel automotive smart high-side driver in PowerSSO-16 package, implementing VIPower® technology to control 12 V grounded resistive/inductive/capacitive loads via 3 V/5 V CMOS-compatible inputs. It delivers 140 mΩ typical on-state resistance per channel, 12 A current limitation, and operates across 4–28 V supply range with ≤0.5 µA standby current. Used in automotive rear lamp modules (e.g., R10W or LED combinations) for precise load switching and diagnostics.
For engineers reviewing the VNQ7140AJTR-E datasheet, VNQ7140AJTR-E pinout, VNQ7140AJTR-E application, or VNQ7140AJTR-E equivalent, key selection criteria include MultiSense analog feedback capability, latch-off configurability via FaultRST, reverse battery protection support, ISO 7637-2 transient immunity, and PowerSSO-16 thermal performance on 2-layer vs. 4-layer PCBs.
Technical Context
The VNQ7140AJTR-E integrates four independent high-side power switches with dedicated logic inputs (INPUT0–3), each featuring internal current limitation (12 A typ), thermal shutdown with configurable latch-off, and undervoltage/overvoltage clamping (40 V transient max). Its protection architecture includes active power limitation during overload, self-limiting fast thermal transients, and detection of short-to-VCC, OFF-state open-load, and loss of ground/VCC.
Diagnostic functionality centers on the multiplexed MultiSense pin, which outputs proportional current representing load current (±5% accuracy), VCC supply voltage, or chip temperature-selected via SEL0–2 and enabled by SEn. FaultRST provides active-low fault reset or auto-restart mode control, while all logic pins are compatible with 3 V/5 V CMOS levels and include hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4–28 V operating; supports full automotive battery range including cold-crank (4 V) and load-dump (up to 40 V transient) |
| RON (per channel) | 140 mΩ typ @ 1 A, 25°C; ensures <1.4 W conduction loss at 10 A, critical for thermally constrained lamp modules |
| ILIMH | 12 A typ current limit; protects against sustained overloads without external fusing in 12 V systems |
| ISTBY | ≤0.5 µA max @ 25°C; enables ultra-low-power module sleep modes compliant with automotive static current budgets |

Pinout & Package
Package: PowerSSO-16 (exposed thermal pad connected to VCC internally; requires soldering to PCB copper for thermal management).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary power rail connection; exposed thermal pad tied to this pin-must be routed to large copper area for heat dissipation |
| GND | Ground reference | System ground return; requires external reverse-battery protection network (e.g., diode/resistor) per datasheet Figure 41 |

| INPUT0–3 | CMOS-compatible control inputs | 3 V/5 V logic-level inputs with hysteresis; directly interfaceable with MCU GPIOs without level-shifting |
| MultiSense | Multiplexed analog diagnostic output | Current-mode output delivering proportional sense of ILOAD, VCC, or TCHIP; requires external ADC or current-sense amplifier |
| SEn | Sense enable control | Active-high signal enabling MultiSense function; allows disabling diagnostics during low-power states to reduce system leakage |
| SEL0–2 | Multiplexer address inputs | 3-bit binary select for MultiSense source (load current, VCC, or temperature); supports shared sense circuitry across multiple drivers |
| FaultRST | Fault reset / latch control | Active-low input that unlatches outputs after overtemperature/power-limit faults-or configures auto-restart behavior when held low |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel automotive high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Higher RON (200 mΩ), no multiplexed analog sense-uses digital SPI for diagnostics | Lacks analog MultiSense; requires MCU with SPI interface and additional firmware for current/voltage/temperature interpretation | Preferred when digital bus integration and functional safety ASIL-B support are required over analog simplicity |
| BD82001FV-M | Single-channel only; 100 mΩ RON; no thermal shutdown latch-off or reverse battery support | Requires four separate ICs and external protection networks-increases PCB area and component count | Only suitable for non-automotive or low-volume designs where cost-per-channel outweighs integration benefits |
Compared with TPS4H160-Q1 and BD82001FV-M, the VNQ7140AJTR-E uniquely combines quad integration, analog MultiSense feedback, latch-off configurability, and reverse battery readiness in one AEC-Q100 qualified device-reducing system-level complexity for lamp and BCM applications.

FAQ
What is the maximum transient voltage the VNQ7140AJTR-E can withstand?
The VNQ7140AJTR-E supports up to 40 V transient supply voltage per ISO 16750-2 Test B (clamped), with internal overvoltage clamp activating at 38–46 V depending on junction temperature. This protects against load-dump events without external TVS diodes in most 12 V automotive architectures.
How does the MultiSense pin deliver three different measurements on one pin?
The MultiSense pin outputs a proportional current (0–10 mA) selected by SEL0–2 address bits and enabled by SEn. With SEL0–2 = 000, it reflects load current; 001 gives VCC supply voltage; 010 returns chip temperature-all scaled linearly and calibrated to ±5% accuracy per datasheet Table 9.
Can the VNQ7140AJTR-E drive inductive loads like solenoids or motors?
Yes-the device supports demagnetization energy up to 10 mJ (VCC = 16 V) and includes active power limitation during inductive turn-off. For solenoid or blower motor control, external freewheeling diodes or RC snubbers are recommended per datasheet Section 5 and Figure 35 to manage flyback voltage spikes.
Is the PowerSSO-16 package RoHS and REACH compliant?
Yes-VNQ7140AJTR-E is manufactured in ST's RoHS-compliant and REACH-conformant facilities. The PowerSSO-16 package uses lead-free matte tin terminations and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), with full compliance documented in ST's official product change notifications and material declarations.
