Product details
Overview
VN7050AJ-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 feedback for load current, VCC, and chip temperature.
For engineers reviewing the VN7050AJ-E datasheet, VN7050AJ-E pinout, VN7050AJ-E application, or VN7050AJ-E equivalent, this page delivers verified technical context, thermal performance data, diagnostic pin mapping, protection architecture, and evaluation board integration guidance specific to automotive load driving.
Technical Context
The VN7050AJ-E implements VIPower® M0-7 technology to combine high-side switching with real-time diagnostics via a multiplexed analog output (MultiSense), supporting simultaneous monitoring of load current (proportional current mirror), supply voltage, and junction temperature using a single pin. It features configurable latch-off behavior triggered by overtemperature or power limitation events.
Protection functions include undervoltage shutdown (VCC < 4 V), overvoltage clamp (40 V transient), fast thermal transient self-limiting, loss-of-ground/VCC detection, and reverse-battery tolerance with external components. Fault reset is managed through an active-low FaultRST pin compatible with 3 V/5 V logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage Range | 4 V to 28 V - supports full 12 V automotive battery range including cold-crank and load-dump conditions |
| Max Transient Supply Voltage | 40 V - enables robust operation during ISO 7637-2 pulse 5a transients without external clamping |
| Typ. On-State Resistance | 50 mΩ - limits conduction loss to ≤1.5 W at 17.3 A continuous load current (P = I²R) |
| Current Limitation (typ) | 30 A - provides short-circuit protection with active power limitation instead of hard current cutoff |
| Standby Current (max) | 0.5 µA - enables always-on modules (e.g., body control units) without measurable battery drain |
| Thermal Resistance (j-amb) | 39 °C/W - measured on 2-layer FR4 PCB (25 × 41.5 mm, 35 µm Cu, thermal vias), defines max ambient temp for 150 °C junction limit |

FAQ
What is the function of the MultiSense pin on VN7050AJ-E?
The MultiSense pin is a multiplexed analog output delivering current proportional to selected diagnostics: load current (via internal current mirror), VCC supply voltage, or chip temperature. Selection is controlled by SEL0/SEL1 pins. It enables real-time health monitoring without additional ADC channels or external sense circuitry.
How does the FaultRST pin operate during thermal shutdown?
FaultRST is an active-low input that unlatches the output after thermal shutdown or power limitation fault. If held low continuously, it forces auto-restart mode; if pulsed low, it resets latched faults once conditions normalize. It requires no external pull-up when interfaced with standard 3 V/5 V CMOS outputs.
Can VN7050AJ-E drive inductive loads like solenoids or motors?
Yes - VN7050AJ-E is qualified for resistive, inductive, and capacitive automotive loads. Its integrated clamp and fast thermal transient self-limiting protect against inductive kickback. External flyback diode is not required, but layout must minimize parasitic inductance in high-current paths per datasheet layout guidelines.
What is the role of the S_EN pin in diagnostic operation?
S_EN is an active-high enable signal for the MultiSense analog output. When low, it disables OFF-state open-load detection and reduces standby current further. It also allows sharing of a single external sense resistor across multiple VN7050AJ-E devices in multi-channel modules to reduce BOM count and PCB area.
