Product details
Overview
VN7140AJTR-E from STMicroelectronics is a single-channel smart high-side power switch in PowerSSO-16 package, designed for 12 V automotive loads with CMOS-compatible 3 V/5 V control, 140 mΩ on-state resistance, 12 A current limit, and integrated MultiSense analog feedback for load current, VCC, and chip temperature.
For engineers reviewing the VN7140AJTR-E datasheet, VN7140AJTR-E pinout, VN7140AJTR-E application, or VN7140AJTR-E equivalent, this evaluation board enables rapid prototyping of automotive high-side switching with diagnostic visibility, thermal protection, and fault reset control-critical for body control modules, lighting, and actuator drivers.
Technical Context
The VN7140AJTR-E implements VIPower® M0-7 technology to deliver robust high-side drive with active power limitation during overload and short-to-ground events. It features configurable latch-off via FaultRST pin and supports OFF-state open-load detection using external pull-up on IN_PullUP.
MultiSense functionality uses a single analog output (MultiSense pin) multiplexed across three diagnostics-load current (proportional current mirror), supply voltage (VCC), and junction temperature-with SEL0/SEL1 addressing and S_EN enable control, all compatible with standard microcontroller GPIOs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage Range | 4 V to 28 V - supports full automotive battery range including cold-crank (4 V) and load-dump (28 V) |
| On-State Resistance (RON) | 140 mΩ typ - limits conduction loss and self-heating at 12 A continuous load |
| Current Limit (ILIMH) | 12 A typ - actively clamps peak current during short-circuit or inrush, preventing MOSFET destruction |
| Standby Current (ISTBY) | 0.5 µA max - enables ultra-low-power sleep mode in always-on vehicle domains |
| Thermal Resistance (Rthj-amb) | 39 °C/W - measured on 2-layer FR4 PCB with thermal vias; defines safe power dissipation envelope |
| MultiSense Output | Multiplexed analog current output - delivers calibrated 1 mA/A load current sense, 0.1 mA/V VCC monitor, and 1 µA/°C temperature readout |

FAQ
What is the function of the FaultRST pin on VN7140AJTR-E?
The FaultRST pin is an active-low input that unlatches the device after thermal shutdown, overcurrent, or short-circuit faults. When held low, it forces auto-restart behavior; when pulsed low then released, it clears latched faults and restores normal operation without cycling VCC.
How does MultiSense work and what signals can it report?
MultiSense is a time-multiplexed analog current output. Using SEL0/SEL1 and S_EN, it sequentially reports load current (1 mA/A), supply voltage (0.1 mA/V), and chip temperature (1 µA/°C). The output requires external ADC sampling synchronized to the SEL inputs.
Can VN7140AJTR-E drive inductive loads like solenoids or motors?
Yes-VN7140AJTR-E integrates fast thermal transient limiting and clamp-based overvoltage protection, enabling safe switching of inductive loads. Its 12 A current limit and 40 V max transient rating accommodate back-EMF spikes typical in automotive solenoids and small DC motors.
Is an external sense resistor required for MultiSense current measurement?
Yes-a sense resistor (RSENSE) must be placed between OUT0 and PGND to enable proportional current mirroring. The board provides pads for through-hole or SMD mounting; value selection (e.g., 5 mΩ–20 mΩ) determines full-scale current range and measurement resolution.
