STMicroelectronics EV-VND9016AJ

Overview

EV-VND9016AJ from STMicroelectronics is an evaluation board pre-assembled with the VND9016AJ dual-channel smart high-side driver in PowerSSO-16 package, rated for 4–28 V operation, 16 mΩ on-state resistance per channel, 50.6 A current limit, and <0.5 µA standby current-designed for automotive load driving and ADAS sensor power protection.

For engineers reviewing the EV-VND9016AJ datasheet, EV-VND9016AJ pinout, EV-VND9016AJ application, or EV-VND9016AJ equivalent, this board enables rapid validation of VND9016AJ's diagnostic feedback (multiplexed analog CS), fault reset (FaultRST), sense enable (SEn), and cold-cranking compliance per LV124 Rev. 2013.

Technical Context

The EV-VND9016AJ implements a hardware-based evaluation platform for the VND9016AJ VIPower M0-9 IC, supporting direct connection of 12 V automotive loads, microcontroller-level CMOS control (3 V/5 V), and real-time diagnostics via multiplexed analog current sense output (CS) and dedicated digital pins (FaultRST, SEn, SEL).

Board-level design includes recommended external components per datasheet: 10 nF C_EXT, 15 kΩ pull-up resistors on VBAT_ADC and CS, zero-ohm jumpers for IN0/IN1 routing, and LED indicators for OUTPUT0/OUTPUT1 status-enabling immediate functional verification without custom PCB layout.

FAQ

What is the purpose of the SEL pin on the EV-VND9016AJ board?

The SEL pin selects between two internal current-sense gain configurations (1:1000 or 1:2000) to optimize analog feedback resolution for different load current ranges. It connects directly to CN9 Pin 1 and is pulled up via R11 (TBD value per configuration); no external logic is required for default operation.

Can the EV-VND9016AJ board drive inductive loads such as solenoids or relays?

Yes-the board supports inductive loads via the VND9016AJ's integrated active clamp and fast thermal transient limiting. The PowerSSO-16 package provides sufficient thermal dissipation, and the board includes recommended snubber components per datasheet guidance for sustained inductive switching at 50.6 A peak.

How is the multiplexed analog current sense (CS) signal decoded on this board?

The CS pin outputs time-multiplexed analog voltage representing either proportional load current (during ON state) or fault codes (short-to-ground, open-load, short-to-VCC) during OFF state. Board test points TP4–TP13 provide access to CS, IN0, IN1, FaultRST, and SEn for oscilloscope-based decoding per DB4936 timing diagrams.

Does the EV-VND9016AJ include reverse battery protection?

No-the board itself does not add reverse polarity protection; however, the underlying VND9016AJ IC features reverse-battery tolerance via self-turn-on limitation of the power MOSFET structure. External reverse-protection diode or TVS is recommended if system-level reverse-battery stress exceeds ±36 V transient limits specified in the device datasheet.
