Product details
Overview
VN7040AJ-E from STMicroelectronics is a single-channel smart high-side power switch fabricated in VIPower® M0-7 technology, housed in PowerSSO-16 package, with 40 mΩ typical on-state resistance, 34 A current limitation, and MultiSense analog feedback (load current, VCC, TCHIP) for automotive load control.
For engineers reviewing the VN7040AJ-E datasheet, VN7040AJ-E pinout, VN7040AJ-E application, or VN7040AJ-E equivalent, this page delivers verified electrical parameters, thermal data, diagnostic pin mapping, protection features, and evaluation board integration guidance for 12 V automotive resistive/inductive/capacitive load switching.
Technical Context
The VN7040AJ-E integrates a high-side MOSFET driver with configurable latch-off fault management via dedicated FaultRST pin, enabling auto-restart or latched shutdown upon overtemperature or power limitation events. It supports 3 V/5 V CMOS-compatible input logic with hysteresis on IN0.
Its MultiSense function multiplexes three diagnostics-proportional load current (via external sense resistor), supply voltage (VCC), and chip temperature-onto a single analog output pin (MultiSense), controlled by SEL0/SEL1 address lines and enabled by S_EN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4–28 V DC: supports full 12 V automotive battery range including cold-crank (4 V) and load-dump (28 V) conditions. |
| On-State Resistance | 40 mΩ typ: enables low conduction loss and minimal self-heating at 10 A continuous load. |
| Current Limitation | 34 A typ: provides robust short-circuit protection without external current-sense amplifiers. |
| Standby Current | 0.5 µA max: ensures negligible battery drain during vehicle sleep mode. |
| Thermal Resistance | 39 °C/W (junct.-ambient): defines maximum power dissipation limit (≈1.3 W) on standard 2-layer FR4 PCB per datasheet layout. |
| Diagnostic Output | Multiplexed analog MultiSense pin: delivers 1:1000 proportional current mirror of load current, ±5% VCC scaling, and 10 µA/°C TCHIP sensing-all selectable via SEL0/SEL1. |
| Fault Reset Logic | Active-low FaultRST: unlatches output after thermal or overload shutdown; held low for auto-restart behavior. |

FAQ
What is the purpose of the MultiSense pin on VN7040AJ-E?
The MultiSense pin is a multiplexed analog output delivering three diagnostics: load current (via external sense resistor), supply voltage (VCC), and chip temperature (TCHIP). Selection is controlled by SEL0/SEL1 inputs, and activation is managed by S_EN. It eliminates need for separate sensing circuits while maintaining ±5% accuracy for VCC and 10 µA/°C linearity for temperature.
How does the FaultRST pin affect fault recovery behavior?
FaultRST is an active-low input that controls latch-off mode. When pulsed low, it unlatches the output after thermal shutdown or current-limit fault. If held continuously low, the device enters auto-restart mode-re-enabling the output after fault condition clears. This enables flexible system-level fault handling without MCU intervention.
Can VN7040AJ-E drive inductive loads like solenoids or motors?
Yes. VN7040AJ-E includes integrated clamp diodes and fast thermal transient limiting, enabling safe switching of inductive loads such as door locks, fuel pumps, and HVAC actuators. Its 34 A current limit and 40 V transient supply rating protect against flyback spikes during turn-off without external snubbers.
What is the role of the S_EN pin in diagnostic operation?
S_EN is an active-high enable signal for the MultiSense analog output. When low, MultiSense is disabled-reducing quiescent current and allowing shared sense resistor usage across multiple VN7040AJ-E devices. This supports low-power module sleep modes and multi-channel diagnostic consolidation in centralized ECUs.
