Product details
Overview
VNLD5090TR-E from STMicroelectronics is an AEC-Q100 qualified, dual-channel monolithic low-side driver IC built with VIPower technology, designed to drive resistive or inductive automotive loads (e.g., solenoids, relays, lamps) with one side connected to battery voltage. It delivers 13 A DC drain current per channel, features 90 mΩ RDS(on) at 25°C, 41 V overvoltage clamp, thermal shutdown with automatic restart, and integrated diagnostics via open-drain STATUS pins.
For engineers reviewing the VNLD5090TR-E datasheet, VNLD5090TR-E pinout, VNLD5090TR-E application, or VNLD5090TR-E equivalent, this page provides verified technical context, SO-8 package details, automotive-grade protection behavior, switching timing (td(OFF) = 3.4 µs), and real-world diagnostic implementation guidance for MCU interface protection.
Technical Context
The VNLD5090TR-E integrates two independent low-side PowerMOS switches with dedicated CMOS-compatible input pins (IN1/VSUPPLY1, IN2/VSUPPLY2) and status reporting (STATUS1, STATUS2). Each channel implements active power limitation during overload and thermal cycling between 135°C reset and 150–200°C shutdown thresholds.
Its protection architecture includes overvoltage clamping at 41–52 V, ESD robustness (5 kV HBM on DRAIN–SUPPLY/INPUT/STATUS), fast demagnetization for inductive loads, and <10 µA standby supply current. The device operates across -40°C to 150°C junction temperature and supports 4.5–5.5 V logic supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Drain Current (ID) | 13 A DC per channel - supports high-power solenoid and lamp loads without external heatsinking under typical automotive ambient conditions. |
| RDS(on) | 90 mΩ max at Tj = 25°C - ensures low conduction loss and minimal self-heating during sustained 10 A operation. |
| VCLAMP | 41–52 V - clamps inductive kickback to protect downstream circuitry and meet ISO 7637-2 pulse 5a requirements. |
| Thermal Shutdown Threshold | 150–200°C - triggers automatic power limiting and recovery cycle to sustain operation after fault clearance. |
| Switching Delay (td(OFF)) | 3.4 µs typ - enables precise PWM control of actuators with minimal dead-time uncertainty. |
| Status Pin Output | Open-drain, 0.5 V low-level at 1 mA - directly interfaces with 3.3 V or 5 V MCU GPIO for real-time fault reporting (overtemp, short-circuit, open-load). |
| ESD Protection | 5 kV HBM on DRAIN/SUPPLY/INPUT/STATUS - eliminates need for external TVS diodes in most board-level ESD test scenarios. |
Pinout & Package
Delivered in SO-8 package (ECOPACK® compliant, RoHS-compliant, moisture sensitivity level 3), with exposed pad for enhanced thermal dissipation. Pin 1 marked by notch or dot; top-view pin numbering follows standard SO-8 layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1/VSUPPLY1 | Channel 1 logic input & supply reference | CMOS-compatible input with hysteresis; supplies internal logic and drives gate of first PowerMOS; accepts 4.5–5.5 V. |
| IN2/VSUPPLY2 | Channel 2 logic input & supply reference | Independent second input/supply rail - enables isolated control of dual loads without shared logic supply dependency. |
| DRAIN1, DRAIN2 | PowerMOS drain terminals | High-current output nodes connected to load; internally clamped to 41–52 V during inductive turn-off. |
| SOURCE1, SOURCE2 | PowerMOS source & ground reference | Common ground return for each channel's load path; also serves as ground reference for respective control section. |
| STATUS1, STATUS2 | Open-drain diagnostic outputs | Active-low fault indicators: pulled low during overtemperature, short-circuit, or undervoltage; high-impedance otherwise. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent low-side drivers | Two fully isolated channels enable simultaneous control of separate actuators (e.g., left/right headlamp, brake + clutch solenoids) with no cross-talk risk. |
| Active power limitation | Reduces dissipated power during prolonged overload to prevent thermal runaway - maintains safe operation until fault clears or shutdown intervenes. |
| Fast demagnetization support | Optimized internal structure enables rapid energy dissipation from inductive loads (e.g., fuel injectors), reducing turn-off delay and EMI generation. |
| Integrated diagnostic feedback | STATUS pins report real-time channel health (open-load, overcurrent, overtemperature) without requiring external sense resistors or ADC monitoring. |
| Ultra-low electromagnetic susceptibility | Validated immunity to automotive-level conducted/radiated noise - eliminates need for additional filtering on control lines in harsh vehicle environments. |
Applications
| Automotive Body Control Module (BCM) | Engine Management System (EMS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN250TR | Single-channel, 2.6 A rated, integrated current sensing; no overvoltage clamp or STATUS pin. | Limited to low-power brushed DC motors; lacks automotive diagnostics and inductive clamp capability. | Select when only basic motor control is needed and cost-per-channel is prioritized over protection depth. |
| TPS4H160-Q1 | Dual-channel, 160 V clamp, 10 A rating, SPI-configurable diagnostics; larger HTSSOP-20 package. | Supports higher bus voltages (24 V commercial vehicles); requires SPI interface and external decoupling. | Choose for 24 V systems or when programmable fault thresholds and advanced telemetry are required. |
Compared with VNLD5090TR-E, STSPIN250TR offers lower integration density and no automotive-grade diagnostics, while TPS4H160-Q1 adds configurability and voltage headroom at the cost of increased footprint and interface complexity - making VNLD5090TR-E optimal for cost-sensitive, 12 V dual-actuator applications demanding plug-and-play protection.

FAQ
What is the maximum continuous drain current per channel at 150°C junction temperature?
The VNLD5090TR-E sustains 13 A DC drain current per channel under specified operating conditions (VIN = 4.5–5.5 V, Tj ≤ 150°C). At elevated temperatures, RDS(on) increases to 180–190 mΩ, raising conduction loss but remaining within safe SO-8 thermal limits when PCB copper area exceeds 2 cm² per channel.
How does the STATUS pin behave during thermal shutdown?
During thermal shutdown, STATUS1 or STATUS2 is actively pulled low (≤0.5 V at 1 mA) to signal overtemperature fault. After junction temperature drops below the reset threshold (135–140°C), the pin returns to high-impedance state within milliseconds, enabling automatic recovery without MCU intervention.
Can unused input pins be left floating?
No - Table 3 explicitly prohibits floating IN1/IN2. Unused inputs must be tied to ground through a 10 kΩ resistor or connected to a valid logic supply. Floating inputs risk undefined switching states, increased EMI susceptibility, and potential latch-up due to internal hysteresis thresholds.
Is external flyback diode required for inductive loads?
No - the integrated source-drain diode (VSD = 0.8 V typ at 1.6 A) and 41 V overvoltage clamp eliminate need for external freewheeling diodes in most 12 V automotive inductive applications. External diodes may still be added for ultra-fast demagnetization in high-frequency PWM scenarios.
