Product details
Overview
VND7012AYTR from STMicroelectronics is a double-channel automotive-grade high-side driver with integrated MultiSense analog feedback, designed for 12 V grounded loads. It features 12 mΩ typical on-state resistance per channel, 75 A current limitation, 4–28 V operating supply range, and AEC-Q100 qualification-used in turn indicators (e.g., 3×P27W), headlamps, and resistive/inductive automotive lighting loads.
For engineers reviewing the VND7012AYTR datasheet, VND7012AYTR pinout, VND7012AYTR application, or VND7012AYTR equivalent, key selection criteria include its dual-channel high-side topology, multiplexed analog sense capability (load current/VCC/temperature), latch-off fault reset via FaultRST, and PowerSSO-36 thermal performance in automotive under-hood environments.
Technical Context
The VND7012AYTR integrates two independent VIPower® M0-7 high-side switches with fully autonomous protection logic-including configurable latch-off on overtemperature or power limitation, undervoltage shutdown (4 V trip), and reverse-battery immunity via self-turn-on. Its MultiSense architecture uses a single analog output pin to sequentially deliver proportional load current (±5% accuracy), VCC supply voltage, and chip temperature via SEL0/SEL1 address control.
Each channel supports CMOS-compatible 3 V/5 V input logic with hysteresis, delivers up to 75 A peak current under short-circuit conditions, and maintains sub-0.5 µA standby current at 25°C. The device implements active power limitation during overload, fast thermal transient self-limiting, and open-load detection in both ON and OFF states using dedicated sensing circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage Range | 4–28 V DC: supports full automotive battery range including cold-crank (4 V) and load-dump (28 V) |
| On-State Resistance (per channel) | 12 mΩ typ @ 7 A, 25°C: enables low conduction loss and <1 W dissipation at 10 A continuous |
| Current Limitation | 75 A typ: sustains short-circuit events without external fusing while limiting energy dissipation |
| Standby Current | 0.5 µA max @ 25°C: minimizes parasitic drain in always-on vehicle modules (e.g., body control units) |
| MultiSense Feedback | Multiplexed analog output (current-proportional): enables single-pin diagnosis of load current, VCC, and TCHIP with ±5% precision |
| Fault Reset | Dedicated active-low FaultRST pin: allows hardware-controlled unlatching after thermal or overload shutdown |
| AEC-Q100 Grade | Qualified to Grade 0 (-40°C to +150°C junction): validated for engine bay and front-end module placement |
Pinout & Package
The VND7012AYTR is housed in a thermally enhanced PowerSSO-36 package with exposed thermal pad (TAB/VCC), optimized for PCB heat spreading in high-power automotive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary power rail connection; also serves as thermal pad (TAB) for heatsinking |
| OUTPUT0, OUTPUT1 | High-side power outputs | Drive grounded loads; each rated for 75 A peak with internal current limiting |
| INPUT0, INPUT1 | CMOS-compatible control inputs | 3 V/5 V logic-level compatible with hysteresis; control respective channel ON/OFF state |
| MultiSense | Multiplexed analog diagnostic output | Delivers proportional current representing load current, VCC, or chip temperature based on SEL0/SEL1 address |
| SEn | Sense enable input | Active-high signal enabling MultiSense output; disables OFF-state diagnostics when low |
| SEL0, SEL1 | MultiSense multiplexer address | Binary-coded inputs selecting diagnostic mode: 00 = load current, 01 = VCC, 10 = TCHIP, 11 = reserved |
| FaultRST | Fault reset input | Active-low pin that unlatches latched fault condition or forces auto-restart mode when held low |
| GND | Power ground reference | Common return path for load current and internal circuitry; isolated from logic ground in layout |
Key Features
| Feature | Design Value |

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 | Single-channel, 160 mΩ RON, no analog current sense-uses digital SPI diagnostics | Lacks multiplexed analog feedback; requires microcontroller interface for diagnostics | Select when system already uses SPI-based diagnostics and lower channel count suffices |
| VND7E025AYTR | Single-channel, 25 mΩ RON, same MultiSense architecture and PowerSSO-36 package | Requires two devices for dual-channel function; identical diagnostic capability per channel | Select when channel independence is critical and board space allows duplication |
Compared with TPS4H160-Q1 and VND7E025AYTR, the VND7012AYTR uniquely delivers dual-channel integration with analog MultiSense feedback in one package-reducing component count, PCB area, and interconnect complexity for automotive lighting and BCM applications requiring simultaneous load control and analog health monitoring.

FAQ
What is the purpose of the FaultRST pin on the VND7012AYTR?
The FaultRST pin is an active-low input that controls fault recovery behavior. When pulsed low, it unlatches a latched fault condition (e.g., thermal shutdown or power limitation). If held continuously low, it configures the device for auto-restart mode-automatically re-enabling outputs after fault clearance without external intervention.
How does MultiSense feedback work and what signals can it report?
MultiSense uses a single analog output pin to deliver current-proportional signals for three diagnostics: load current (±5% accuracy), VCC supply voltage, and chip temperature. Selection is controlled by SEL0/SEL1 inputs: 00 = load current, 01 = VCC, 10 = TCHIP. SEn must be high to enable output; OFF-state open-load detection occurs independently of MultiSense activation.
Can the VND7012AYTR drive inductive loads like radiator fans safely?
Yes-the VND7012AYTR includes built-in demagnetization energy handling (144 mJ max at VCC = 16 V) and active power limitation during inductive turn-off transients. Its reverse-battery immunity and thermal shutdown with configurable latch-off ensure robust operation with motor loads, provided PCB copper area meets JEDEC JESD51-7 thermal guidelines for PowerSSO-36.
Is the VND7012AYTR pin-compatible with other ST high-side drivers in PowerSSO-36?
No-VND7012AYTR has a unique pin assignment optimized for dual-channel operation and MultiSense multiplexing. While other ST PowerSSO-36 drivers (e.g., VND7E025AYTR) share the same package outline, pin functions differ significantly; direct replacement requires schematic and layout revision due to distinct INPUT, SEL, SEn, and FaultRST routing requirements.
