Product details

Overview

VND7140AJ-E from STMicroelectronics is a dual-channel smart high-side power switch in PowerSSO-16 package, designed for 12 V automotive loads with CMOS-compatible 3 V/5 V control inputs. It delivers typ. 140 mΩ on-state resistance per channel, 12 A current limitation, and integrated MultiSense analog feedback for load current, VCC, and chip temperature - deployed in engine control modules for solenoid actuation.

For engineers reviewing the VND7140AJ-E datasheet, VND7140AJ-E pinout, VND7140AJ-E application, or VND7140AJ-E equivalent, this page provides verified package mapping, validated diagnostic pin functions (MultiSense, FaultRST, S_EN), confirmed thermal resistance (39 °C/W), and real-world automotive load interface constraints.

Technical Context

The VND7140AJ-E implements VIPower M0-7 technology to integrate high-side switching, real-time current sensing via proportional mirror, and multiplexed analog diagnostics on a single die. It supports configurable latch-off on overtemperature or power limitation, with dedicated FaultRST pin for active-low fault recovery or auto-restart mode.

Its protection architecture includes undervoltage shutdown, overvoltage clamp, self-limiting thermal transients, and detection of open-load (OFF-state), short-to-VCC, and short-to-ground - all managed without external supervision logic.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4 V to 28 V - supports full automotive battery range including cold-crank (4 V) and load-dump (28 V)
R_ON (typ)	140 mΩ per channel - enables <1.7 W conduction loss at 12 A, reducing heatsink requirements
I_LIMH (typ)	12 A - sets hard current limit during overload, preventing fuse blow and wiring damage
I_STBY (max)	0.5 µA - allows permanent connection to battery in always-on modules (e.g., body control units)
R_thj-amb	39 °C/W - defines thermal derating slope on standard 2-layer FR4 PCB (25 × 41.5 mm, 35 µm Cu)
MultiSense Output	Multiplexed analog current source - delivers 1:2000 proportional current for load current, VCC, or T_CHIP with <±5% accuracy
FaultRST Logic	Active-low CMOS-compatible input - resets latched faults or enables auto-restart when held low

FAQ

What is the function of the MultiSense pin on VND7140AJ-E?

The MultiSense pin is a multiplexed analog current output delivering a 1:2000 proportional current representing load current, VCC supply voltage, or chip junction temperature - selected via SEL0/SEL1 digital inputs. It enables single-pin diagnosis without ADC channel proliferation in microcontroller designs.

How does FaultRST affect latch-off behavior?

FaultRST is an active-low input that unlatches outputs after overtemperature or power-limit faults. When held low, it forces auto-restart mode instead of latched shutdown - allowing continuous operation in non-critical applications where transient overloads are expected.

Can VND7140AJ-E drive inductive loads like fuel injectors?

Yes - the device integrates fast thermal transient limiting and active power limitation during overload, making it suitable for automotive inductive loads including fuel injectors and solenoids. Its 12 A current limit and 40 V max transient VCC rating withstand typical injector flyback spikes.

Is external sense resistor required for MultiSense functionality?

No - MultiSense operates internally using a proportional current mirror; however, an external sense resistor (RSENSE) is required only if high-precision absolute current measurement is needed beyond the built-in 1:2000 scaling. The board provides pads for through-hole or SMD RSENSE mounting.
