STMicroelectronics VND7030AJTR-E

Overview

VND7030AJTR-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. 31 mΩ on-state resistance per channel, 56 A current limitation, and integrated MultiSense analog feedback for load current, VCC, and chip temperature - used in engine control modules for solenoid and relay driving.

For engineers reviewing the VND7030AJTR-E datasheet, VND7030AJTR-E pinout, VND7030AJTR-E application, or VND7030AJTR-E equivalent, key selection criteria include diagnostic multiplexing capability, latch-off configurability via FaultRST, thermal shutdown behavior, and compatibility with automotive-grade PCB thermal vias and sense-resistor configurations.

Technical Context

The VND7030AJTR-E implements VIPower M0-7 technology to integrate high-side switching, real-time diagnostics, and protection logic in a single die. Its MultiSense pin multiplexes three analog signals (load current, VCC, TCHIP) using SEL0/SEL1 address lines, while FaultRST enables configurable latch-off reset behavior.

It supports OFF-state open-load detection via external pull-up on IN_PullUP and provides active overload management through power limitation rather than hard current cutoff. Protection includes undervoltage shutdown, overvoltage clamp, reverse battery tolerance (with external components), and loss-of-ground/VCC detection.

FAQ

What is the function of the FaultRST pin?

FaultRST is an active-low input that unlatches outputs after thermal shutdown, overload, or short-circuit faults. When held low, it forces auto-restart mode; when pulsed low then released, it resets latched faults without cycling VCC. It is CMOS-compatible with both 3 V and 5 V logic levels.

How does MultiSense work and what signals does it provide?

MultiSense is a single-pin, time-multiplexed analog current output. Using SEL0/SEL1, it sequentially delivers current proportional to load current (I_OUT), supply voltage (V_CC), or chip temperature (T_CHIP). No external op-amp or ADC reference is required - the current is ratiometric to internal bandgap references.

Can VND7030AJTR-E drive inductive loads like fuel injectors?

Yes - it is qualified for automotive inductive loads with integrated clamping and fast transient suppression. The device limits energy dissipation during turn-off via active power limitation and includes dedicated short-to-VCC detection, making it suitable for injector and valve coil driving in engine control units.

What PCB layout practices are recommended for thermal performance?

ST specifies a 2-layer FR4 board with 35 µm copper, 1.6 mm thickness, and thermal vias (0.5 mm diameter, 1.1 mm spacing) under the exposed pad. The PowerSSO-16 package requires soldering the exposed thermal pad to a minimum 100 mm² copper pour connected to PGND for R_thj-amb ≤ 39 °C/W.
