Product details
Overview
VND7140AJ12TR-E from STMicroelectronics is a double-channel automotive high-side driver in PowerSSO-12 package, delivering 140 mΩ on-state resistance per channel, 12 A current limitation, and analog CurrentSense feedback with multiplexed diagnostics. It operates from 4 V to 28 V supply, supports deep-cranking down to 2.85 V, and drives grounded resistive/inductive loads such as automotive rear lamps (R10W or LED combinations).
For engineers reviewing the VND7140AJ12TR-E datasheet, VND7140AJ12TR-E pinout, VND7140AJ12TR-E application, or VND7140AJ12TR-E equivalent, key selection criteria include cranking voltage margin, analog current sense accuracy, thermal shutdown behavior, and CMOS-compatible 3 V/5 V input logic compatibility.
Technical Context
The device integrates two independent VIPower® high-side switches with embedded protection logic including active power limitation during overload, thermal shutdown at 140 °C (cranking mode), and undervoltage lockout with 0.3 V hysteresis. Each channel features dedicated INPUTx pins with hysteresis and supports standalone or synchronized control via SEL/SEn.
CurrentSense functionality provides time-multiplexed analog output proportional to load current (±5% accuracy), plus diagnostic flags for short-to-VCC, off-state open-load, thermal shutdown, and overcurrent - all selectable via SEL and enabled/disabled via SEn.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage Range | 4 V to 28 V - supports full automotive battery range including cold-cranking transients |
| Min Cranking Voltage | 2.85 V - enables operation during engine start under extreme low-voltage conditions (LV124 compliant) |
| On-State Resistance | 140 mΩ typ. @ 1 A, 25°C - limits conduction loss and self-heating in 12 V systems |
| Current Limit Threshold | 12 A typ. - protects against sustained overload while allowing inrush for lamp filaments |
| Standby Current | 0.5 µA max. @ 25°C - minimizes parasitic drain in always-on vehicle modules |
| CurrentSense Accuracy | ±5% @ IOUT = 0.1–10 A - enables precise closed-loop load monitoring without external shunt |
| Thermal Shutdown Temp | 140 °C (cranking mode) - maintains safe operation during transient thermal stress |
Pinout & Package
Package: PowerSSO-12 (exposed die pad, thermally enhanced surface-mount package with integrated heatsink capability).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Accepts up to 40 V transient clamped supply; powers internal circuitry and output stages |
| GND | Ground reference | Must be reverse-battery protected externally; serves as return path for load and logic currents |
| OUTPUT0, OUTPUT1 | High-side power outputs | Drive grounded loads; each includes reverse-diode clamp and current-limiting protection |
| INPUT0, INPUT1 | CMOS-compatible control inputs | Hysteresis-enabled; compatible with both 3 V and 5 V MCU I/Os; direct ON/OFF control |
| CurrentSense | Analog diagnostic output | Multiplexed current-proportional signal (1 mA/A); carries overload, thermal, and fault status |
| SEn | Sense enable control | Active-high logic input; disables CurrentSense output during standby to reduce system leakage |
| SEL | Multiplexer address select | Controls which channel's current or diagnostic flag appears on CurrentSense pin |
Key Features
| Feature | Design Value |
|---|---|
| Double-channel VIPower® HSD | Independent control of two 12 V loads with shared diagnostics and thermal coupling management |
| Deep-cranking support | Guaranteed operation down to 2.85 V supply - meets LV124 Rev 2013 for cold-start reliability |
| Integrated CurrentSense | Single-pin analog multiplexing eliminates need for external current-sense amplifiers or ADC channels |
| Loss-of-ground detection | Monitors GND integrity continuously; triggers fault reporting if ground path opens or degrades |
| Reverse-battery readiness | Supports external Schottky or MOSFET-based GND protection networks per ISO 16750-2 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Single-channel, 160 mΩ RON, no analog CurrentSense - uses digital SPI diagnostics only | Lacks multiplexed analog feedback; requires external ADC or SPI interface for current data | Preferred when digital bus integration and lower channel count outweigh analog sensing needs |
| VND7050AJTR-E | Single-channel, 500 mΩ RON, 5 A ILIM, same PowerSSO-12 package and pinout subset | Lower current rating and higher RON limit use to smaller loads like LEDs or solenoids | Drop-in replacement where reduced power handling and simplified diagnostics suffice |
Compared with TPS4H160-Q1 and VND7050AJTR-E, the VND7140AJ12TR-E uniquely delivers dual-channel analog current feedback in a single package - enabling compact, sensorless load monitoring ideal for lamp control and BCM consolidation without sacrificing cranking robustness.

FAQ
What is the maximum transient voltage the VND7140AJ12TR-E can withstand?
The device supports up to 40 V transient supply voltage per ISO 16750-2 Test B, with internal clamping limiting VCC spikes. This rating applies under specified test conditions (RL = 4 Ω), and the clamp voltage reaches 41 V at 25°C. The absolute maximum DC supply voltage is 38 V, and reverse battery tolerance requires external GND protection components.
How does the CurrentSense pin deliver multiplexed diagnostics?
The CurrentSense pin outputs either analog load current (1 mA/A) or diagnostic flags - short-to-VCC, off-state open-load, thermal shutdown, or overload - based on SEL and SEn states. When SEn = high and SEL = low, Channel 0 current is reported; SEL = high selects Channel 1. Diagnostic flags appear as voltage levels defined in Table 16 of the datasheet.
Is the VND7140AJ12TR-E pin-compatible with other PowerSSO-12 high-side drivers?
No - while it shares the PowerSSO-12 footprint, its pin functions differ significantly from single-channel variants like VND7050AJTR-E (missing SEL/SEn and second INPUT/OUTPUT). Pin mapping is unique to this dual-channel CurrentSense architecture; PCB layout must follow Figure 2 and Table 1 in the official datasheet.
Does the device support PWM dimming for LED loads?
Yes - the VND7140AJ12TR-E supports PWM frequencies up to 5 kHz with controlled dV/dt (0.1–0.7 V/µs), minimizing EMI and ensuring reliable switching. Its 140 mΩ RON and fast turn-off delay (<100 µs) maintain efficiency and thermal stability during high-duty-cycle modulation used in automotive LED tail lamps.
