Product details
Overview
VN7140AS-E from STMicroelectronics is a single-channel smart high-side power switch in PowerSSO-16 package, designed for 12 V automotive grounded loads with 3 V/5 V CMOS-compatible control, 140 mΩ typical on-state resistance, 12 A current limitation, and integrated MultiSense analog feedback for load current, VCC, and chip temperature.
For engineers reviewing the VN7140AS-E datasheet, VN7140AS-E pinout, VN7140AS-E application, or VN7140AS-E equivalent, this evaluation board enables rapid prototyping of automotive load driving with diagnostic visibility, thermal protection, and fault reset functionality - critical for body control modules, lighting, and HVAC actuators.
Technical Context
The VN7140AS-E implements VIPower® M0-7 technology to combine power switching and real-time diagnostics in one die. It features a configurable latch-off fault recovery via dedicated FaultRST pin and supports OFF-state open-load detection only when S_EN is asserted.
MultiSense output delivers time-multiplexed analog signals: proportional load current (high-precision current mirror), supply voltage (VCC), and junction temperature (TCHIP), all referenced to PGND and selectable via SEL0/SEL1 logic inputs.
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) |
| Max Transient Supply Voltage | 40 V - withstands ISO 7637-2 pulse 5a without external clamping |
| Typ. On-State Resistance | 140 mΩ - limits conduction loss to ≤2.0 W at 12 A, enabling compact thermal design |
| Current Limitation (ILIMH) | 12 A (typ) - active power-limiting protects against sustained overload and short-to-ground |
| Standby Current | 0.5 µA (max) - enables always-on modules without battery drain |
| Thermal Resistance (Rthj-amb) | 39 °C/W - measured on 2-layer FR4 PCB (25 × 41.5 mm, 35 µm Cu, thermal vias) |
| Diagnostic Multiplexing | SEL0/SEL1 address 3-channel analog sense - allows single ADC input to monitor load, supply, and temperature |

FAQ
What is the function of the FaultRST pin on VN7140AS-E?
FaultRST is an active-low input that unlatches the output after overtemperature or power-limiting faults. When held low, it forces auto-restart mode; when pulsed low, it clears latched faults. It is CMOS-compatible with both 3 V and 5 V logic levels and requires no external pull-up resistor.
How does MultiSense feedback work and what signals does it provide?
MultiSense is a multiplexed analog output delivering three diagnostic signals sequentially: load current (via precision current mirror), VCC supply voltage, and TCHIP junction temperature. Selection is controlled by SEL0/SEL1 logic inputs, and output is enabled only when S_EN is high - allowing shared ADC use across multiple channels.
Can VN7140AS-E drive inductive loads like solenoids or motors?
Yes - VN7140AS-E integrates fast thermal transient self-limiting and active power limitation to safely manage inductive kickback and surge currents. Its built-in clamp and undervoltage/overvoltage protections ensure reliable operation with solenoids, relays, and small DC motors in 12 V automotive systems.
Is an external sense resistor required for MultiSense operation?
Yes - a sense resistor (RSENSE) must be placed between TP1 and TP2 (or soldered on designated SMD pads) to enable load current sensing. The board includes a through-hole position for user-selected values; typical RSENSE = 5 mΩ yields ~2.4 mA per ampere of load current at the MultiSense pin.
