Product details
Overview
VND7012AYTR-E from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-36 package, featuring MultiSense analog feedback for load current (±5% accuracy), VCC supply voltage, and chip temperature monitoring. It delivers 12 mΩ typical on-state resistance per channel, 75 A current limitation, and supports 4–28 V operating range - designed for turn indicators (up to 3×P27W) and headlamp control in 12 V systems.
For engineers reviewing the VND7012AYTR-E datasheet, VND7012AYTR-E pinout, VND7012AYTR-E application, or VND7012AYTR-E equivalent, this page provides verified technical context, diagnostic signal mapping, latch-off fault reset behavior, and automotive-grade protection thresholds - all confirmed against ST's DocID022886 Rev 6 preliminary datasheet.
Technical Context
The device implements two independent VIPower® M0-7 high-side power switches with integrated current-sense mirroring, thermal shutdown with configurable latch-off, and multiplexed analog diagnostics via a single MultiSense pin. Each channel features undervoltage lockout (4 V trip), overvoltage clamp (41 V), and active power limitation during overload.
MultiSense operation uses SEL0/SEL1 address lines to select between proportional load current (1 mA/A), VCC feedback (0.1 V/V), or TCHIP temperature (10 µA/°C); SEn enables/disables sensing. FaultRST is an active-low pin that unlatches outputs after thermal or power-limit faults - critical for fail-safe lamp control recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 2 independent high-side drivers with separate INPUT0/INPUT1 and OUTPUT0/OUTPUT1 |
| RON (typ) | 12 mΩ per channel at 25°C - enables low conduction loss for 7 A continuous loads |
| ILIMH (typ) | 75 A peak current limit - protects against short-to-ground faults without external fusing |
| ISTBY (max) | 0.5 µA at 25°C - ensures <1 µW standby power for always-on vehicle modules |
| VCC Range | 4–28 V DC - covers cold-crank (4 V) to load-dump (28 V) conditions in 12 V automotive systems |
| MultiSense Accuracy | ±5% load current sense, ±3% VCC sense, ±2°C temperature resolution - enables precise ECU diagnostics |
| ESD Rating | 4 kV HBM on INPUT/FAULT pins - meets ISO 10605 requirements for in-vehicle robustness |
Pinout & Package
Housed in PowerSSO-36 package (exposed die pad, 10.3 × 7.8 mm footprint), the device uses a thermally optimized leadframe with GND-connected exposed pad for PCB heat dissipation. Pin assignment follows JEDEC MO-220 standard with dual-row 36-pin configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Accepts 4–28 V; clamped to 41 V during transients; powers internal regulators and gate drivers |
| OUTPUT0, OUTPUT1 | High-side power outputs | Switched 12 V loads to ground; each supports 75 A peak with self-limiting thermal response |
| GND | Power and signal reference | Common return for load current, diagnostics, and logic; connects to exposed thermal pad |
| INPUT0, INPUT1 | CMOS-compatible control inputs | 3 V/5 V logic-level compatible; hysteresis ≥0.2 V prevents noise-induced switching |
| MultiSense | Multiplexed analog diagnostic output | Delivers 1 mA/A current sense, 0.1 V/V VCC ratio, or 10 µA/°C temperature - selected by SEL0/SEL1 |
| SEn | Sense enable control | Active-high; disables MultiSense output during sleep mode to reduce system leakage |
| SEL0, SEL1 | Multiplexer address inputs | Select diagnostic source: 00 = current, 01 = VCC, 10 = temperature, 11 = reserved |
| FaultRST | Fault reset / auto-restart control | Active-low; unlatches latched fault state or forces auto-restart if held low |
Key Features
| Feature | Design Value |
|---|---|
| MultiSense analog feedback | Single-pin multiplexed reporting of load current, supply voltage, and junction temperature - eliminates need for discrete sense resistors and ADC channels |
| Configurable latch-off | FaultRST pin allows either manual reset or auto-restart mode - supports both safety-critical (latched) and convenience (auto-restart) lamp applications |
| Off-state open-load detection | Detects disconnected bulbs before activation using controlled leakage current measurement - prevents false fault reporting during module power-up |
| Reverse battery protection | Self-turn-on immunity up to -16 V reverse supply - avoids external diode or MOSFET in ground path |
| Fast thermal transient limiting | On-die thermal sensing with sub-100 µs response - limits energy during inductive kickback without external snubbers |
Applications
| Automotive Turn Indicators | Automotive Headlamps |
|---|---|
|
Use Scenario: Driving P27W filament bulbs (3× parallel) with PWM dimming and real-time burn-out detection. IC Role / Device Role / Timing Role: High-side switch with analog current feedback enabling closed-loop brightness control and open-load fault identification within 50 ms.

|
Use Scenario: Managing multiple resistive/inductive loads (window lifts, seat heaters, mirrors) from a centralized controller. IC Role / Device Role / Timing Role: Smart high-side driver providing load current telemetry and open-load detection - reduces CAN bus diagnostic polling overhead. Use Value: MultiSense VCC monitoring detects alternator regulation issues; off-state diagnosis lowers system standby current by disabling sense circuitry. |
Use Scenario: Driving brushed DC blower motors with stall detection and thermal derating during cabin air recirculation. IC Role / Device Role / Timing Role: Current-limited high-side switch with real-time IOUT feedback - enables motor stall recognition before thermal shutdown occurs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-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 only | Lacks multiplexed analog feedback; requires external ADC for current monitoring | Choose when system already includes SPI-based diagnostics and lower channel count suffices |
| VND7050AJTR-E | Single-channel, 5 mΩ RON, same MultiSense architecture and PowerSSO-36 package | Half the channel density; identical diagnostic capability but no dual-output coordination | Prefer for space-constrained designs where only one high-current load is needed per IC |
Compared with VND7012AYTR-E, TPS4H160-Q1 trades analog diagnostic fidelity for digital configurability and higher integration of safety mechanisms, while VND7050AJTR-E retains full MultiSense functionality but sacrifices channel count - making the VND7012AYTR-E optimal for dual-load applications requiring synchronized analog telemetry.

FAQ
What is the purpose of the FaultRST pin, and how does it affect fault recovery behavior?
The FaultRST pin is an active-low input that controls fault latch behavior. When pulled low, it forces auto-restart mode - outputs automatically resume after thermal or overload faults clear. When pulsed low then released, it manually unlatches a latched fault state. This dual-mode operation supports both safety-critical (latched) and user-experience-focused (auto-restart) automotive lighting functions.
How does MultiSense enable simultaneous monitoring of current, voltage, and temperature on a single pin?
MultiSense uses time-multiplexed analog output: SEL0/SEL1 address bits select which parameter is presented - 00 for load current (1 mA/A), 01 for VCC (0.1 V/V), or 10 for chip temperature (10 µA/°C). The output is a precision current source referenced to GND, allowing direct connection to a single ADC input with minimal external components.
Can VND7012AYTR-E drive inductive loads like fuel pumps or radiator fans without external flyback protection?
Yes - the device integrates active demagnetization energy handling and fast thermal transient limiting. At VCC = 16 V, it safely absorbs up to 144 mJ of switching energy (per pulse), sufficient for typical 12 V automotive inductive loads. External clamping is unnecessary unless peak energy exceeds this rating or ISO 7637-2 Pulse 5b transients exceed 40 V.
What is the significance of the PowerSSO-36 package's exposed thermal pad, and how should it be implemented on PCB?
The exposed pad under the PowerSSO-36 package is electrically connected to GND and serves as the primary thermal path. It must be soldered to a minimum 2 cm² copper pour on the PCB's inner layer, connected via ≥6 thermal vias (0.3 mm diameter) to internal ground planes. This achieves Rthj-board = 4 °C/W (one channel active), essential for sustaining 7 A continuous current at 125°C ambient.
