Product details
Overview
VNQ7140AJ-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 - enabling precise load switching and diagnostics in automotive lighting modules.
For engineers reviewing the VNQ7140AJ-E datasheet, VNQ7140AJ-E pinout, VNQ7140AJ-E application, or VNQ7140AJ-E equivalent, this page provides verified functional identity, validated MultiSense analog feedback behavior, confirmed PowerSSO-16 thermal performance, and real-world diagnostic coverage for signal lamp and rear combination LED/R10W load control.
Technical Context
The VNQ7140AJ-E integrates four independent high-side power switches with embedded protection logic including configurable latch-off on overtemperature or power limitation, undervoltage shutdown (4 V), and reverse-battery tolerance with external components. Each channel features active current limitation (12 A typ.) and self-limiting thermal transient response.
Its MultiSense architecture multiplexes three analog diagnostics - proportional load current (±5% accuracy), VCC supply voltage, and TCHIP temperature - onto a single output pin using SEL0/SEL1/SEL2 address lines and SEn enable control. FaultRST provides active-low fault reset or auto-restart mode selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC operating range | 4–28 V: Supports full automotive battery range including cold-crank (4 V) and load-dump (28 V) conditions without external regulation. |
| RON (per channel) | 140 mΩ typ. @ 1 A, 25°C: Enables low conduction loss and minimal self-heating during continuous 5 A lamp drive. |
| ILIMH | 12 A typ.: Limits peak short-circuit current to protect wiring harness and upstream fusing in headlamp or foglamp circuits. |
| ISTBY | 0.5 µA max. @ 25°C: Allows module-level sleep-mode compliance in body control units with multi-week battery drain budgets. |
| MultiSense resolution | Proportional current mirror with ±5% accuracy: Enables closed-loop current monitoring for LED brightness regulation and open-load detection. |
| FaultRST function | Active-low configurable latch: Permits either manual fault recovery (via MCU GPIO) or automatic restart after thermal cooldown. |
| ESD rating | 4 kV HBM on INPUT/OUTPUT pins: Meets ISO 16750-2 surge immunity requirements for under-hood ECUs. |
Pinout & Package
Package: PowerSSO-16 (exposed thermal pad connected to VCC), surface-mount, RoHS-compliant, rated for -40°C to +150°C junction operation. Thermal resistance Rthj-amb = 26.8°C/W on 4-layer PCB (JEDEC JESD 51-7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary 12 V rail connection; internal clamp limits transients to 40 V; exposed thermal pad tied to this node. |
| GND | Ground reference | Must be protected against reverse battery with external diode/resistor network per datasheet Figure 41. |
| INPUT0–3 | CMOS-compatible control inputs | Hysteresis-enabled; compatible with 3 V/5 V MCUs; direct interface to STM32 or NXP S32K without level-shifting. |
| OUTPUT0–3 | High-side switched outputs | Drive grounded lamps/relays; support inductive kickback energy dissipation up to 10 mJ (VCC = 16 V). |
| MultiSense | Multiplexed analog diagnostic output | Delivers IOUT, VCC, or TCHIP as proportional current; requires external 10 kΩ pull-up to VCC for voltage readout. |
| SEn | Sense enable | Active-high; disables OFF-state open-load detection during low-power sleep to reduce system leakage. |
| SEL0–2 | Multiplexer address lines | Select diagnostic source: 000 = IOUT, 001 = VCC, 010 = TCHIP; unused states reserved. |
| FaultRST | Fault reset / latch control | Active-low; held low → auto-restart mode; pulsed low → unlatch fault and resume normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel VIPower® high-side switching | Four independent channels with integrated gate drivers, eliminating need for external MOSFETs and bootstrap circuitry in lamp control modules. |
| MultiSense analog feedback | Single-pin multiplexed sensing of load current, supply voltage, and die temperature - reduces BOM count and PCB routing complexity vs. discrete sense solutions. |
| Configurable fault latch-off | FaultRST pin allows OEMs to select between manual recovery (for safety-critical systems) or auto-restart (for non-critical lighting) without firmware changes. |
| Reverse battery protection support | Internal clamp and GND pin design enable robust reverse-polarity handling when paired with external diode (DGND) per Figure 41 - critical for service bay jump-start scenarios. |
| Ultra-low standby current | 0.5 µA max. at 25°C enables >10-year battery life in always-on vehicle modules such as interior ambient lighting controllers. |
Applications

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 |
|---|---|---|---|
| TLE7234SE | Higher RON (200 mΩ), no MultiSense, only digital fault flags (open-drain), 5 V-only logic interface. | Lacks analog current/voltage/temperature feedback; requires external ADC and sense resistors for closed-loop control. | Choose when cost sensitivity outweighs diagnostic richness and system-level BOM reduction is secondary. |
| TPS4H160-Q1 | Lower current limit (8 A), integrated charge pump, SPI interface instead of analog MultiSense, 16-bit fault register. | Digital diagnostics require MCU SPI stack integration; no native analog current mirroring for LED dimming feedback. | Prefer when centralized fault logging via CAN/SPI is required and analog sensor fusion is not needed. |
Compared with TLE7234SE and TPS4H160-Q1, the VNQ7140AJ-E uniquely combines analog MultiSense feedback, ultra-low standby current, and 12 A current capability in a single PowerSSO-16 package - making it optimal for cost-sensitive, space-constrained automotive lighting where analog diagnostics and long-term battery retention are mandatory.

FAQ
What is the maximum safe operating temperature for VNQ7140AJ-E?
The VNQ7140AJ-E has a guaranteed junction operating temperature range of -40°C to +150°C per AEC-Q100 Grade 0. Its thermal shutdown activates at ~170°C (TSD), but continuous operation above 150°C is not recommended. On a 4-layer PCB with 2s2p layout, Rthj-amb = 26.8°C/W allows ~4.5 W total power dissipation before reaching 150°C at 85°C ambient.
How does MultiSense distinguish between load current, VCC, and chip temperature?
MultiSense uses SEL0–SEL2 address lines to configure an internal multiplexer: SEL = 000 selects proportional load current (IOUT × 1/250), 001 selects VCC (scaled 1:10), and 010 selects TCHIP (linear voltage vs. temperature). SEn must be high for any measurement; each mode has dedicated timing windows defined in Figures 7 and 8.
Can VNQ7140AJ-E drive inductive loads like radiator fans without external flyback diodes?
No - external freewheeling diodes are required across inductive loads. The device supports demagnetization energy up to 10 mJ (VCC = 16 V, TDEMAG = 0.4 ms), but internal clamping alone cannot handle sustained inductive kickback. Datasheet Figure 35 shows recommended diode placement from OUTPUT to GND.
Is the PowerSSO-16 package lead-free and RoHS-compliant?
Yes - VNQ7140AJ-E is manufactured in a lead-free, halogen-free PowerSSO-16 package compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3). The exposed thermal pad is electrically connected to VCC and must be soldered to a thermal copper plane per datasheet Section 6.
