Product details
Overview
VND7050AJTR from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-16 package, delivering 50 mΩ typical on-resistance per channel, 30 A current limitation, and multiplexed analog MultiSense feedback for load current, VCC supply voltage, and chip temperature. It operates from 4–28 V, supports 3 V/5 V CMOS inputs, and is AEC-Q100 qualified for signal lamp control (e.g., SAE1156, P27W, LED rear combinations).
For engineers reviewing the VND7050AJTR datasheet, VND7050AJTR pinout, VND7050AJTR application, or VND7050AJTR equivalent, this page provides verified electrical specs, diagnostic behavior under fault conditions, thermal resistance data (Rthj-amb = 25 °C/W on 4-layer PCB), and real-world design guidance for reverse-battery protection and latch-off configuration.
Technical Context
The VND7050AJTR integrates two independent VIPower® M0-7 high-side switches with configurable latch-off on overtemperature or power limitation, controlled via dedicated FaultRST pin. Its MultiSense output delivers time-multiplexed analog signals-load current (±5% accuracy), VCC (±3%), and TCHIP (±5 °C)-using a single pin with SEL0/SEL1 addressing.
Protections include undervoltage shutdown (4 V trip, 5 V reset), 40 V transient clamp, self-limiting fast thermal transients, and detection of OFF-state open-load, short-to-VCC, and loss of ground/VCC. Standby current remains ≤0.5 µA at 25 °C with all inputs low and SEn disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4–28 V operating; supports full automotive battery range including cold-crank (4 V) and load-dump (40 V transient clamped) |
| RON (per channel) | 50 mΩ typ @ 2 A, 25 °C; ensures <100 mV drop at 2 A, minimizing power loss and heat generation |
| ILIMH | 30 A typ current limit; protects against sustained overload without external fusing |
| ISTBY | 0.5 µA max @ 25 °C; enables ultra-low-power module sleep modes in body control units |
| Rthj-amb | 25 °C/W (JEDEC JESD51-7, 4-layer PCB); allows ~2.4 W continuous dissipation per channel at ΔT = 60 °C |
| MultiSense Accuracy | ±5% for load current sense; enables precise closed-loop current monitoring for LED brightness regulation |
| AEC-Q100 Grade | Grade 0 (−40 to +150 °C junction); qualified for engine bay and headlamp ECU placement |
Pinout & Package
Package: PowerSSO-16 (exposed die pad, thermally enhanced, RoHS-compliant surface-mount package with 0.65 mm pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Accepts 4–28 V DC; clamped to 40 V during ISO 7637-2 transients; requires external reverse-battery protection network |
| OUTPUT0, OUTPUT1 | High-side switched outputs | Drive grounded resistive/inductive/capacitive loads; each rated for 30 A peak, with integrated current limiting and thermal shutdown |
| GND | Power ground reference | Must be protected externally against reverse battery; connects to PCB thermal pad for heatsinking |
| INPUT0, INPUT1 | CMOS-compatible control inputs | 3 V/5 V logic compatible with hysteresis; drive internal gate drivers directly-no level-shifting needed |
| MultiSense | Multiplexed analog diagnostic output | Delivers proportional current for ILOAD, VCC, or TCHIP; requires external 10 kΩ pull-up resistor to VCC for voltage-mode readout |
| SEn | Sense enable control | Active-high; disables MultiSense output in standby to reduce system leakage; enables sharing across multiple devices |
| SEL0, SEL1 | Multiplexer address inputs | Select diagnostic mode: 00 = ILOAD, 01 = VCC, 10 = TCHIP, 11 = reserved; sampled synchronously with SEn edge |
| FaultRST | Fault reset/latch control | Active-low; unlatches outputs after thermal or overload shutdown; held low for auto-restart mode |
Key Features
| Feature | Design Value |
|---|---|
| MultiSense analog diagnostics | Single-pin multiplexed sensing of load current (±5%), supply voltage (±3%), and chip temperature (±5 °C) reduces BOM count and routing complexity |
| Configurable latch-off | FaultRST pin enables either manual reset or auto-restart mode-critical for safety-critical lamp control where flicker must be avoided |
| Ultra-low standby current | ≤0.5 µA at 25 °C allows integration into always-on vehicle modules without battery drain concerns |
| Reverse battery tolerance | Supports −0.3 V VCC with external diode/resistor GND network-meets ISO 16750-2 requirements for automotive environments |
| Integrated protections | Combines undervoltage lockout, overvoltage clamp, current limitation, thermal shutdown, open-load detection, and short-to-VCC detection in one die |
Applications
| Automotive Signal Lamps | Body Control Modules (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Higher RON (160 mΩ), no analog MultiSense; uses digital SPI for diagnostics | Lacks analog current/voltage/temperature multiplexing; requires MCU with SPI interface and additional firmware | Preferred when digital bus communication and ASIL-D support are required over analog simplicity |
| BD82002FV-M | Single-channel only; lower current limit (15 A); no fault reset pin or latch-off configuration | Requires two devices for dual-channel operation; no configurable auto-restart mode | Only suitable for cost-sensitive, non-safety-critical applications where diagnostics are secondary |
Compared with TPS4H160-Q1 and BD82002FV-M, the VND7050AJTR uniquely combines dual-channel integration, analog MultiSense on one pin, and hardware-configurable latch behavior-making it optimal for space-constrained, analog-centric automotive lighting modules needing minimal MCU overhead.

FAQ
What is the maximum continuous output current per channel?
The VND7050AJTR does not specify a fixed "continuous" current rating due to thermal dependence. At Tj = 150 °C and Rthj-amb = 25 °C/W (4-layer PCB), each channel sustains ~2.4 W dissipation, supporting ~7 A DC with 50 mΩ RON. For 30 A peak, pulse width must be limited per SOA curves in Section 2.5 of the datasheet.
How is MultiSense calibrated for accurate current sensing?
MultiSense delivers a proportional current (ISENSE = K × IOUT, K ≈ 1/200) with ±5% total error over −40 to +150 °C. Calibration is factory-trimmed; no user adjustment is needed. External 10 kΩ pull-up converts ISENSE to voltage (e.g., 10 mA → 100 mV), readable by any 12-bit ADC with ≥10 mV LSB resolution.
Can FaultRST be left unconnected?
No. FaultRST must be actively driven: pulled high (≥2.0 V) for normal operation with latch-off, or held low (≤0.8 V) for auto-restart mode. Floating FaultRST causes undefined behavior-datasheet Table 2 specifies "Through 15 kΩ resistor to VCC" if unused, but functional designs require intentional biasing.
Does VND7050AJTR support PWM dimming of LEDs?
Yes. With turn-on/turn-off times <1 µs (typ) and no minimum off-time requirement, the device supports PWM frequencies up to 20 kHz. Its low RON and integrated current limiting prevent thermal stress during rapid switching, and MultiSense enables real-time current monitoring for closed-loop brightness control.
