STMicroelectronics VND7030AJ-E

Overview

VND7030AJ-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 31 mΩ on-state resistance per channel, 56 A current limitation, and integrated MultiSense analog feedback for load current, VCC, and chip temperature - deployed in engine control modules for solenoid and relay driving.

For engineers reviewing the VND7030AJ-E datasheet, VND7030AJ-E pinout, VND7030AJ-E application, or VND7030AJ-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 VND7030AJ-E implements VIPower M0-7 technology to integrate high-side switching, real-time current sensing, and fault management in a single die. Its MultiSense pin multiplexes three diagnostics - proportional load current (via precision current mirror), supply voltage, and junction temperature - using SEL0/SEL1 address lines and S_EN enable control.

Protection architecture includes undervoltage lockout, overvoltage clamping at 40 V transient, self-limiting thermal transients, and configurable latch-off on overtemperature or power limitation. FaultRST provides active-low reset for latched faults or enables auto-restart mode when held low.

FAQ

What is the function of the FaultRST pin?

FaultRST is an active-low input that unlatches outputs after overtemperature or current-limit faults. When held low, it forces auto-restart mode instead of latched shutdown. It accepts 3 V/5 V CMOS logic levels and requires no external pull-up for basic operation, though a 10 kΩ pull-up is recommended for noise immunity in noisy automotive environments.

How does MultiSense feedback work and what signals can it report?

MultiSense is a single-pin, time-multiplexed analog current output delivering three diagnostics: load current (proportional 1:2000 mirror), VCC supply voltage (1:10 scaling), and chip temperature (10 µA/°C). Selection is controlled by SEL0/SEL1 and enabled by S_EN. External RC filtering (e.g., 10 nF + 10 kΩ) is required at the MCU ADC input to reconstruct each signal.

Can VND7030AJ-E drive inductive loads like fuel injectors or solenoids?

Yes - the device integrates fast freewheeling path management and active overload handling to safely commutate inductive loads. Its 56 A current limit and self-limiting thermal response prevent destructive energy buildup during turn-off. External flyback diodes are not required, but layout must minimize parasitic inductance in the PGND path to avoid voltage overshoot.

What is the recommended sense resistor value for accurate current measurement?

ST recommends 1 mΩ to 5 mΩ for RSENSE depending on resolution vs. power trade-off. With 1 mΩ, 25 A yields 25 mV across the resistor - compatible with standard 12-bit ADCs. The evaluation board supports through-hole (TP1–TP2) or 0805 SMD mounting. Accuracy is ±5% typical due to internal current mirror tolerance and PCB trace resistance effects.
