STMicroelectronics VN7016AJTR-E

Overview

VN7016AJTR-E from STMicroelectronics is a single-channel smart high-side power switch in PowerSSO-16 package, designed for 12 V automotive grounded loads with CMOS-compatible 3 V/5 V control. It delivers 16 mΩ on-state resistance, 77 A current limitation, and integrated MultiSense analog feedback for load current, VCC, and chip temperature - deployed in engine control modules and body electronics.

For engineers reviewing the VN7016AJTR-E datasheet, VN7016AJTR-E pinout, VN7016AJTR-E application, or VN7016AJTR-E equivalent, key selection criteria include diagnostic multiplexing capability (SEL0/SEL1), fault reset behavior (FaultRST), sense enable control (S_EN), and thermal resistance (39 °C/W) under automotive ambient conditions.

Technical Context

The VN7016AJTR-E implements VIPower® M0-7 technology to combine power switching and real-time diagnostics in one die. Its MultiSense output uses time-multiplexed current mirroring to deliver proportional signals for load current (±5% accuracy), supply voltage (VCC), and junction temperature (TCHIP), selectable via SEL0/SEL1 logic.

Protection architecture includes configurable latch-off on overtemperature or power limitation, undervoltage/overvoltage clamping, loss-of-ground/VCC detection, and reverse-battery tolerance with external components. FaultRST is active-low and supports both auto-restart (held low) and manual unlatch (pulsed low).

FAQ

What is the function of the MultiSense pin?

The MultiSense pin is a time-multiplexed analog current output delivering proportional signals for load current, VCC supply voltage, and chip temperature. Selection is controlled by SEL0/SEL1 inputs. It eliminates need for separate sense amplifiers and ADC channels, reducing system component count and PCB area.

How does FaultRST behave during thermal shutdown?

During thermal shutdown, VN7016AJTR-E enters latch-off mode. Applying a low pulse (≥1 µs) to FaultRST unlatches the output and restores normal operation if temperature has dropped below threshold. Holding FaultRST low forces auto-restart mode, continuously attempting re-enabling while fault persists.

Can S_EN be used to disable diagnostics during sleep mode?

Yes. Driving S_EN low disables all MultiSense functions, including OFF-state open-load detection, reducing quiescent current and preventing false diagnostics during MCU sleep. This allows coordinated low-power sequencing between host controller and driver.

Is an external sense resistor required for current monitoring?

No external sense resistor is required for basic diagnostics. The internal current mirror enables load current sensing directly. However, RSENSE (mounted on TP1–TP2 or SMD pads) is needed only if higher absolute accuracy or custom gain scaling is required beyond the device's built-in ±5% sensing tolerance.
