Product details
Overview
VN7040ASTR-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 for load current, VCC, and chip temperature - used in automotive body control modules to drive resistive/inductive loads.
For engineers reviewing the VN7040ASTR-E datasheet, VN7040ASTR-E pinout, VN7040ASTR-E application, or VN7040ASTR-E equivalent, key selection criteria include its 4–28 V operating range, 0.5 µA standby current, fault reset (FaultRST) pin behavior, latch-off configuration options, and multiplexed analog diagnostic output compatibility with 3 V/5 V microcontrollers.
Technical Context
The VN7040ASTR-E implements a high-side driver architecture with integrated protection logic including undervoltage shutdown, overvoltage clamp, and self-limiting thermal transients. Its MultiSense pin delivers time-multiplexed analog signals: proportional load current (via precision current mirror), VCC supply voltage, and TCHIP temperature - all selectable via SEL0/SEL1 digital inputs.
It supports configurable latch-off on overtemperature or power limitation, with active fault recovery via active-low FaultRST. The S_EN pin enables/disables OFF-state open-load detection, allowing low-power mode optimization and shared external sense resistor configurations across multiple channels.
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) conditions |
| Typ. On-State Resistance | 40 mΩ - limits conduction loss to ≤1.36 W at 5.8 A continuous load current |
| Current Limitation (ILIMH) | 34 A (typ) - provides robust short-circuit protection without external current-sense amplifiers |
| Standby Current | ≤0.5 µA - enables ultra-low quiescent power in always-on vehicle modules |
| MultiSense Output | Multiplexed analog current output - enables single-pin diagnostics for load current, VCC, and die temperature with <±5% accuracy |
| Fault Reset Input | Active-low FaultRST - allows manual or MCU-controlled unlatching after thermal or overload faults |
| Thermal Resistance (Rthj-amb) | 39 °C/W - defines maximum junction temperature rise under PCB layout per FR4 spec (2-layer, 35 µm Cu, thermal vias) |

FAQ
What is the function of the MultiSense pin on VN7040ASTR-E?
The MultiSense pin is a multiplexed analog current output that sequentially delivers signals proportional to load current, supply voltage (VCC), and chip temperature. Selection is controlled by SEL0 and SEL1 inputs. It eliminates need for separate sensing circuits and supports diagnostic monitoring using a single ADC channel on the host MCU.
Does VN7040ASTR-E support auto-restart after fault conditions?
Yes - when FaultRST is held low, the device enters auto-restart mode after thermal shutdown or current-limiting events. In normal operation, FaultRST must be pulsed low to unlatch the output following a latched fault condition, enabling controlled recovery.
Can VN7040ASTR-E drive inductive loads like solenoids or relays?
Yes - it integrates fast transient thermal limiting and active power limitation during overload, making it suitable for driving automotive inductive loads. External flyback diode is required across the load to suppress inductive kickback, as specified in the datasheet layout guidelines.
What is the role of the S_EN pin in VN7040ASTR-E?
S_EN is an active-high enable input for the MultiSense diagnostic function. When low, it disables OFF-state open-load detection and reduces quiescent current. It also permits sharing of a single external sense resistor among multiple VN7040ASTR-E devices in multi-channel designs.
