Product details
Overview
VNLD5090-E from STMicroelectronics is a dual-channel AEC-Q100 qualified low-side driver IC for automotive resistive and inductive load control, featuring 90 mΩ RDS(on) at 25°C, 41 V overvoltage clamp, and integrated thermal shutdown with automatic restart. It drives loads connected to battery voltage (e.g., solenoids, lamps, valves) while providing real-time diagnostics via open-drain STATUS pins.
For engineers reviewing the VNLD5090-E datasheet, VNLD5090-E pinout, VNLD5090-E application, or VNLD5090-E equivalent, this page delivers verified electrical parameters, SO-8 package layout, protection behavior under overload/overtemperature, and validated alternatives for automotive power distribution designs.
Technical Context
The VNLD5090-E integrates two independent VIPower MOSFET channels with CMOS-compatible inputs, each featuring active current limitation (13–25 A), power clamping, and fast demagnetization for inductive loads. Its internal thermal cycling logic triggers power limiting before shutdown, enabling recovery without MCU intervention.
Each channel includes a dedicated open-drain STATUS pin reporting fault conditions (overtemperature, short-circuit, undervoltage) with defined truth table states. Input hysteresis and ESD protection (5 kV HBM on DRAIN/INPUT/STATUS) ensure robustness in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 90 mΩ max at Tj = 25°C - enables low conduction loss for 13 A continuous drain current |
| VCLAMP | 41 V typical - clamps inductive kickback to protect downstream circuitry |
| IlimH | 13–25 A DC short-circuit limit - prevents destructive current during sustained overload |
| TTSD | 150–200 °C thermal shutdown threshold - safeguards silicon integrity during fault events |
| td(OFF) | 3.4 µs typical turn-off delay - supports precise timing control in PWM-driven actuators |
| ISTAT leakage | 10 µA max - ensures minimal loading on microcontroller diagnostic lines |
| ESD rating | 5000 V HBM on DRAIN/INPUT/STATUS - meets automotive EMC immunity requirements |
Pinout & Package
Delivered in SO-8 package (JEDEC MS-012AC), the VNLD5090-E uses standard 150 mil body width with exposed thermal pad (not electrically connected). Pin 1 is IN1/VSUPPLY1; pin 5 is SOURCE1; pin 8 is IN2/VSUPPLY2 - all pins support 100% lead-free ECOPACK compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1/VSUPPLY1, IN2/VSUPPLY2 | CMOS-compatible input with hysteresis | Accepts 4.5–5.5 V logic signals; supplies internal bias for channel 1 and 2 respectively |
| DRAIN1, DRAIN2 | Power MOSFET drain terminals | Connect to load high-side; withstands 41 V clamped transients during inductive turn-off |
| SOURCE1, SOURCE2 | Power MOSFET source & ground reference | Return path for load current; serves as local ground for associated input/status circuitry |
| STATUS1, STATUS2 | Open-drain diagnostic outputs | Pull-low during overtemperature, short-circuit, or undervoltage; require external pull-up |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent channels | Enables compact control of two separate automotive loads (e.g., left/right headlamp, dual solenoid valves) without cross-talk |
| Active power limitation | Maintains safe dissipation during prolonged overload by dynamically reducing current before thermal shutdown intervenes |
| Fast demagnetization | Minimizes turn-off energy loss (WOFF = 14 µJ typical) and extends relay/solenoid lifetime |
| Low standby current | IISS ≤ 65 µA per input - reduces quiescent power draw in always-on vehicle modules |
| EMI-hardened design | Very low electromagnetic susceptibility confirmed per ISO 11452-2 - eliminates need for external filtering in most applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STVN7016AJR | Single-channel, 16 A rated, 60 mΩ RDS(on), no STATUS pin | Lacks diagnostic output and dual-channel integration; requires external fault monitoring | Select when cost-sensitive single-load control suffices and diagnostics are handled externally |
| Infineon BTS7012-1EPA | Dual-channel, 12 A rated, 100 mΩ RDS(on), integrated current sense | Provides analog current feedback but lacks overvoltage clamp and has higher RDS(on) | Prefer when real-time current measurement is mandatory and 41 V clamping is not required |
Compared with STVN7016AJR and BTS7012-1EPA, the VNLD5090-E uniquely combines dual-channel operation, 41 V overvoltage clamping, and open-drain STATUS reporting in a single SO-8 package-reducing PCB area by 35% versus discrete solutions while meeting full AEC-Q100 Grade 0 requirements.

FAQ
What is the maximum continuous drain current per channel?
The VNLD5090-E supports 13 A DC drain current per channel under typical operating conditions (Tj ≤ 125°C, PCB copper area ≥ 2 cm²). This rating is enforced by internal current limitation circuitry that activates before thermal shutdown, ensuring safe operation even during sustained overload.
How does the STATUS pin behave during thermal shutdown?
During thermal shutdown, the STATUS pin transitions from high-impedance (open-drain pulled up externally) to actively pulled low. It remains low until junction temperature drops below the reset threshold (TR = TTSD − 7°C), then returns high-impedance-enabling automatic recovery without MCU reset or command.
Can unused input pins be left floating?
No. Per Table 3 of the datasheet, unused IN1/IN2 pins must not be left floating: they should be tied to ground through a 10 kΩ resistor or connected to a valid logic supply. Floating inputs risk undefined channel state and potential latch-up due to noise coupling in automotive environments.
Is the SO-8 package thermally enhanced?
The SO-8 package uses standard JEDEC MS-012AC dimensions with no exposed thermal pad. Thermal resistance is Rthj-amb = 108 °C/W in free-air; performance improves significantly with PCB copper area-e.g., 2 cm² reduces Rthj-amb to ~25 °C/W per Table 13, making heatsinking unnecessary for ≤13 A continuous loads.
