Product details
Overview
VN7020AJTR-E from STMicroelectronics is a dual-channel automotive smart high-side driver in PowerSSO-16 package, designed to control 12 V grounded resistive/inductive/capacitive loads via 3 V/5 V CMOS-compatible inputs. It delivers 20 mΩ typical on-state resistance per channel, 63 A current limitation, and integrated MultiSense analog feedback for load current, chip temperature, and supply voltage sensing. Used in automotive turn indicators (e.g., dual P27W or LED rear combinations) and protected ADAS sensor supplies.
For engineers reviewing the VN7020AJTR-E datasheet, VN7020AJTR-E pinout, VN7020AJTR-E application, or VN7020AJTR-E equivalent, key selection criteria include AEC-Q100 qualification, configurable latch-off fault recovery, multiplexed analog diagnostics, reverse battery protection support, and thermal shutdown with 150 °C trip point.
Technical Context
This device implements dual independent high-side switches using ST's VIPower® M0-7 technology, with each channel featuring active current limiting, dynamic thermal management, and undervoltage/overvoltage clamping. The integrated MultiSense architecture uses a single analog output pin (MultiSense) to sequentially deliver proportional current sense (K-factor range 550–3070 A/A), chip temperature (−40 to 125 °C linear response), and VCC voltage (VSENSE_VCC = VCC/4).
Control logic includes hysteresis on INPUT, SEL0/SEL1 address lines for diagnostic multiplexing, SEn enable, and active-low FaultRST for latched fault reset. Protection functions operate autonomously: overload triggers power limitation before thermal shutdown, OFF-state open-load detection requires external pull-up, and short-to-VCC is sensed via output voltage monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance | 20 mΩ typ. per channel at 3 A, 25 °C - enables low conduction loss and minimal self-heating during sustained load drive. |
| Current limitation | 63 A typ. DC short-circuit limit - provides robust overload handling without external fusing in automotive lighting applications. |
| Standby current | 0.5 µA max. at 13 V, 25 °C - supports ultra-low-power module sleep states in body control modules. |
| Supply voltage range | 4 to 28 V operating - covers full automotive battery range including cold-crank (4 V) and load-dump (28 V) conditions. |
| Thermal shutdown | 150 °C trip temperature with 7 K hysteresis - prevents permanent damage during sustained overloads while enabling safe auto-restart or latch-off modes. |
| MultiSense accuracy | ±10% current sense error at 3 A (uncalibrated); ±5% after calibration - enables reliable real-time load monitoring for diagnostics and functional safety compliance. |
| ESD rating | 4 kV HBM on INPUT, MultiSense, SEn, SELx, FaultRST - ensures robustness against assembly and in-vehicle electrostatic events. |
Pinout & Package
Package: PowerSSO-16 (exposed thermal pad connected to VCC). Pin count: 16 terminals, with 4 OUTPUT pins (pins 7, 11, 12, 13) internally bonded together as a single high-current output node; 2 N.C. pins (pins 8, 10); TAB = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary power rail connection; also tied to exposed thermal tab for enhanced heat dissipation. |
| OUTPUT | High-side power output | Four pins (7,11,12,13) paralleled to handle up to 63 A; must be connected together externally. |
| GND | Ground reference | Return path for control circuitry; requires external reverse-battery protection diode/resistor network. |
| INPUT | CMOS-compatible switch control | Hysteresis-enabled digital input compatible with both 3 V and 5 V logic; controls channel ON/OFF state. |
| MultiSense | Multiplexed analog diagnostic output | Delivers current-proportional, temperature-proportional, or VCC-proportional current; requires external 1 kΩ–2.7 kΩ sense resistor. |
| SEn | MultiSense enable | Active-high signal that activates analog feedback; allows disabling diagnostics during low-power mode. |
| SEL0, SEL1 | Multiplexer address inputs | Select diagnostic source: 00 = load current, 01 = chip temperature, 11 = VCC voltage. |
| FaultRST | Active-low fault reset | Pulls low to unlatch outputs after thermal or overload fault; held low for auto-restart behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel high-side switching | Two independent VIPower® M0-7 outputs sharing one MultiSense pin - reduces BOM count and PCB area vs. discrete solutions. |
| MultiSense analog feedback | Single-pin multiplexed sensing of IOUT (550–3070 A/A), TCHIP (−40 to 125 °C), and VCC (VCC/4) - eliminates need for separate ADC channels or external sensors. |
| Configurable fault recovery | FaultRST pin enables either auto-restart (latched low) or manual reset (pulsed low) - supports fail-safe or fail-operational system architectures. |
| AEC-Q100 Grade 1 qualification | Rated for −40 to 125 °C ambient operation with full characterization - meets automotive reliability requirements for under-hood and cabin applications. |
| Reverse battery protection support | With external diode/resistor network on GND - enables use in vehicles with unregulated battery systems without additional protection ICs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart 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/voltage/temperature monitoring. | Choose when SPI-based diagnostics suffice and lower channel count reduces system complexity. |
| VNQ7050AJTR-E | Dual-channel, 50 mΩ RON, 5 A ILIMH, same PowerSSO-16 package and MultiSense architecture. | Lower current capability suits smaller loads like interior lighting or small solenoids; shares identical control interface. | Choose for cost-sensitive designs where 5 A per channel is sufficient and thermal margin is less constrained. |
Compared with VN7020AJTR-E, TPS4H160-Q1 trades analog diagnostic fidelity for digital configurability and higher integration density, while VNQ7050AJTR-E offers identical feature set at reduced current rating - making it suitable for lower-power automotive subsystems where footprint and interface compatibility are prioritized over peak drive capability.

FAQ
What is the function of the FaultRST pin?
FaultRST is an active-low pin that unlatches the output after a thermal shutdown or overload fault. When pulled low, it resets the latch and restores normal operation; if held continuously low, it configures the device for auto-restart mode instead of latched-off behavior. Its logic thresholds (0.9 V low, 2.1 V high) ensure compatibility with standard 3 V/5 V CMOS drivers.
How does MultiSense distinguish between load current, chip temperature, and VCC voltage?
MultiSense uses SEL0 and SEL1 address lines to select one of three diagnostic modes: SEL0=0/SEL1=0 for load current (ISENSE = IOUT/K), SEL0=0/SEL1=1 for chip temperature (VSENSE_TC = 2.07 V at 25 °C, −5.5 mV/K slope), and SEL0=1/SEL1=1 for VCC voltage (VSENSE_VCC = VCC/4). SEn must be high to enable any mode.
Can VN7020AJTR-E drive inductive loads like fuel injectors or solenoids?
Yes - it supports inductive loads with built-in demagnetization clamp (VDEMAG = VCC − 41 V typical) and fast transient energy handling (EMAX = 64 mJ). The device limits dV/dt during turn-off (0.1–0.32 V/µs) to reduce EMI, and its 63 A current limit protects against inrush surges. External flyback diode is not required due to internal clamp structure.
What is the recommended external component for MultiSense analog readout?
A 1 kΩ to 2.7 kΩ pull-down resistor between MultiSense and GND is required to convert the proportional output current into a measurable voltage. ST recommends 2.7 kΩ for optimal resolution in current-sense mode (e.g., 3 A → ~5 V), and 1 kΩ for temperature/VCC sensing to maintain linearity across full ranges. Resistor tolerance should be ≤1% for calibrated applications.
