STMicroelectronics VN7050AJTR-E

Overview

VN7050AJTR-E from STMicroelectronics is a single-channel smart high-side power switch in PowerSSO-16 package, designed for 12 V automotive grounded loads with 3 V/5 V CMOS-compatible control, 50 mΩ on-state resistance, 30 A current limitation, and integrated MultiSense analog diagnostic feedback.

For engineers reviewing the VN7050AJTR-E datasheet, VN7050AJTR-E pinout, VN7050AJTR-E application, or VN7050AJTR-E equivalent, this evaluation board enables rapid prototyping of automotive load driving with real-time current, voltage, and temperature sensing, fault latching, and configurable protection thresholds.

Technical Context

The VN7050AJTR-E implements VIPower® M0-7 technology to combine high-voltage ruggedness (40 V transient supply) with precise analog diagnostics via a multiplexed MultiSense output pin. It supports OFF-state open-load detection, short-to-VCC and short-to-ground protection, and thermal shutdown with latch-off configuration via FaultRST.

Its control interface features hysteresis on IN0 input, compatibility with 3 V/5 V logic, and dedicated S_EN, SEL0, SEL1 pins to configure diagnostic channel selection. Protection includes undervoltage lockout, overvoltage clamping, self-limiting thermal transients, and reverse battery support with external components.

FAQ

What is the function of the FaultRST pin on VN7050AJTR-E?

FaultRST is an active-low pin that unlatches the output after overtemperature or power limitation faults. When held low, it forces auto-restart behavior instead of latched-off state. It is compatible with both 3 V and 5 V CMOS logic levels and requires no external pull-up for basic operation.

How does the MultiSense pin deliver diagnostics?

The MultiSense pin outputs a proportional current (typically 1 mA/A for load current) selected via SEL0/SEL1. It sequentially reports load current, supply voltage (VCC), and chip temperature (TCHIP) as analog signals, enabling single-pin diagnosis without additional ADC channels on the host MCU.

Can VN7050AJTR-E drive inductive loads like solenoids or motors?

Yes - it integrates fast thermal transient limiting and active power limitation during overload, making it suitable for automotive inductive loads. External flyback diodes are recommended for inductive kick suppression, and layout must follow ST's thermal vias and copper pour guidelines to maintain Rthj-amb ≤39 °C/W.

Is VN7050AJTR-E AEC-Q100 qualified?

Yes - VN7050AJTR-E is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), with full characterization across temperature, voltage, and lifetime stress tests. This qualification is documented in ST's official device qualification report, not just claimed in marketing material.
