Product details
Overview
VND7140AJTR from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-16 package, featuring MultiSense analog feedback, 140 mΩ typical on-state resistance per channel, 12 A current limitation, and AEC-Q100 qualification. It drives grounded resistive/inductive loads (e.g., R10W lamps or LED rear combinations) via 3 V/5 V CMOS-compatible inputs with integrated diagnostics and protection.
For engineers reviewing the VND7140AJTR datasheet, VND7140AJTR pinout, VND7140AJTR application, or VND7140AJTR equivalent, this page delivers verified electrical specs, validated diagnostic functions (load current, VCC, TCHIP sensing), fault handling behavior (latch-off/reset), thermal performance on 2-layer vs 4-layer PCBs, and real-world automotive load interface requirements.
Technical Context
The device implements dual independent high-side switches using ST's VIPower® M0-7 technology, each with programmable current limiting, thermal shutdown with configurable latch-off, and reverse-battery protection support via external components. Its MultiSense pin multiplexes three analog signals-proportional load current, supply voltage, and chip temperature-using dedicated SEL0/SEL1 address lines and SEn enable control.
Protection architecture includes undervoltage shutdown (4 V trip, 5 V reset), overvoltage clamp (41–52 V), self-limiting fast thermal transients, and detection of OFF-state open-load, short-to-VCC, and short-to-ground. Fault recovery is managed through the active-low FaultRST pin, supporting both auto-restart and latched fault modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4 V to 28 V operating supply - supports full automotive battery range including cold-crank (4 V) and load-dump (28 V) |
| RON (typ) | 140 mΩ per channel at 1 A, 25°C - enables low conduction loss for 12 A peak loads without external heatsink |
| ILIMH (typ) | 12 A current limit - provides robust overload protection for lamp and solenoid drivers |
| ISTBY (max) | 0.5 µA standby current - meets ultra-low-power requirements for always-on automotive modules |
| Tj Range | −40°C to +150°C junction temperature - qualified for under-hood deployment per AEC-Q100 Grade 0 |
| MultiSense Outputs | Multiplexed analog current output for ILOAD, VCC, TCHIP - eliminates need for separate ADC channels or external sense resistors |
| ESD Rating | 4 kV HBM on INPUT/OUTPUT/MultiSense pins - ensures robustness against assembly and system-level ESD events |
Pinout & Package
Package: PowerSSO-16 (exposed die pad, thermally enhanced SO-16 variant, JEDEC MS-012AC compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary power rail connection; clamped to 40 V transient, supports ISO 16750-2 pulse testing |
| OUTPUT0, OUTPUT1 | High-side power outputs | Drive grounded loads; integrate reverse-battery diode structure (VF = 0.7 V @ −1 A, 150°C) |
| GND | Power ground reference | Must be externally protected against reverse battery with diode/resistor network per datasheet Fig. 35 |
| INPUT0, INPUT1 | CMOS-compatible control inputs | 3 V/5 V logic compatible with hysteresis; drive internal gate drivers directly |
| MultiSense | Multiplexed analog diagnostic output | Current-mode output proportional to selected parameter (ILOAD, VCC, TCHIP) - requires external 10 kΩ pull-up to VCC |
| SEn | Sense enable control | Active-high signal enabling MultiSense function; allows disabling diagnostics during low-power sleep mode |
| SEL0, SEL1 | Multiplexer address inputs | Select diagnostic source: 00 = ILOAD, 01 = VCC, 10 = TCHIP, 11 = reserved |
| FaultRST | Fault reset/latch control | Active-low pin; unlatches outputs after fault or forces auto-restart when held low |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Single-channel, 160 mΩ RON, no analog MultiSense; uses digital SPI diagnostics | Lacks multiplexed analog feedback; requires MCU with SPI interface and additional ADC resources | Preferred when digital diagnostics and higher channel count per package are prioritized over analog simplicity |
| VND7050AJTR | Single-channel, 500 mΩ RON, same MultiSense architecture and package | Lower current capability (4 A typ.) and higher conduction loss - unsuitable for R10W lamp loads | Selected only for space-constrained designs requiring identical footprint but lower power dissipation |
Compared with TPS4H160-Q1 and VND7050AJTR, the VND7140AJTR uniquely combines dual-channel 12 A capability, ultra-low standby current, and analog MultiSense in one AEC-Q100-qualified PowerSSO-16 package - making it optimal for cost-sensitive, thermally constrained lamp and body control applications requiring minimal external components.

FAQ
What is the maximum transient voltage the VND7140AJTR can withstand?
The VND7140AJTR supports up to 40 V transient supply voltage per ISO 16750-2 Test B (clamped condition), with a maximum jump-start voltage of 28 V. Its internal overvoltage clamp activates at 41–52 V depending on junction temperature, protecting downstream circuitry without external TVS diodes in most automotive scenarios.
How does the MultiSense pin deliver three different measurements on a single output?
The MultiSense pin outputs a proportional current (not voltage) that corresponds to load current, VCC, or chip temperature based on SEL0/SEL1 address bits and SEn enable state. Internal analog multiplexing routes the selected signal to a current mirror; external 10 kΩ pull-up converts it to a measurable voltage, with timing diagrams in Figures 7–8 defining sampling windows.
Can the VND7140AJTR drive inductive loads like fuel injectors without external flyback protection?
No - while the device integrates reverse-battery protection and has built-in demagnetization energy handling (10 mJ at VCC = 16 V), external freewheeling diodes or RC snubbers are required for inductive loads exceeding its specified EMAX. Datasheet Section 5 defines maximum demagnetization energy limits and recommends external components for solenoids and injectors.
What is the role of the FaultRST pin in latch-off versus auto-restart configurations?
When FaultRST is pulled high, faults (overtemperature, overload) trigger latch-off - outputs remain disabled until a deliberate low pulse resets them. When FaultRST is held low, the device enters auto-restart mode: outputs cycle ON/OFF periodically until fault condition clears, enabling fail-operational behavior for non-critical loads like cabin lighting.
