STMicroelectronics VN7016AJ-E

Overview

VN7016AJ-E from STMicroelectronics is a single-channel smart high-side power switch fabricated in VIPower® M0-7 technology, housed in PowerSSO-16 package, with 16 mΩ typical on-state resistance, 77 A current limitation, and MultiSense analog feedback for load current, VCC, and chip temperature - used for driving 12 V automotive grounded resistive/inductive loads via 3 V/5 V CMOS interface.

For engineers reviewing the VN7016AJ-E datasheet, VN7016AJ-E pinout, VN7016AJ-E application, or VN7016AJ-E equivalent, key selection criteria include diagnostic multiplexing (SEL0/SEL1), fault reset (FaultRST), sense enable (S_EN), thermal shutdown latch configuration, and compatibility with automotive supply ranges (4–28 V).

Technical Context

The VN7016AJ-E integrates a high-side MOSFET driver with embedded protection logic including undervoltage lockout, overvoltage clamping, and self-limiting thermal transients. Its MultiSense architecture uses a single analog output (MultiSense pin) time-multiplexed across three diagnostics: proportional load current (via precision current mirror), VCC supply voltage, and junction temperature - all selectable via SEL0/SEL1 digital inputs.

It supports configurable fault handling: latch-off on overtemperature or power limitation is enabled by default but can be disabled via FaultRST pin held low (auto-restart mode). The device also provides OFF-state open-load detection, short-to-VCC detection, and loss-of-ground/VCC monitoring - all implemented in silicon without external components.

FAQ

What is the function of the S_EN pin on VN7016AJ-E?

The S_EN (Sense Enable) pin is an active-high CMOS-compatible input that controls activation of the MultiSense analog diagnostic output. When low, it disables all analog sensing functions - including load current, VCC, and temperature feedback - reducing quiescent current and enabling shared sense resistor usage across multiple channels in multi-output modules.

How does the FaultRST pin affect latch-off behavior?

When pulled high, FaultRST enables standard latch-off operation: the output remains off after overtemperature or overload until externally reset. When held low, the device enters auto-restart mode - automatically attempting re-enabling every ~10 ms after fault clearance, provided VCC and thermal conditions are within specification.

Can VN7016AJ-E drive inductive loads like solenoids or motors?

Yes - the VN7016AJ-E is qualified for inductive load switching in automotive applications. Its integrated clamp diode (via internal architecture) and fast thermal transient limiting protect against back-EMF-induced stress. External flyback diodes are not required, though layout best practices (short traces, local decoupling) must be followed per ST AN4600 guidelines.

What is the purpose of the J3 connector pins SEL0 and SEL1?

SEL0 and SEL1 are active-high CMOS-compatible address inputs that configure the 2-bit multiplexer selecting which parameter appears on the MultiSense pin: 00 = load current, 01 = VCC, 10 = chip temperature, 11 = reserved. They allow full diagnostic coverage using only one ADC input channel on the host microcontroller.
