Product details
Overview
VND7020AJTR-E from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-16 package, integrating MultiSense analog feedback for load current (±5% accuracy), VCC supply voltage, and chip temperature sensing. It delivers 22 mΩ on-state resistance per channel, 63 A current limitation, and supports 4–28 V operation with <0.5 µA standby current-designed for turn indicator control in 12 V vehicle systems.
For engineers reviewing the VND7020AJTR-E datasheet, VND7020AJTR-E pinout, VND7020AJTR-E application, or VND7020AJTR-E equivalent, key selection criteria include latch-off configurability via FaultRST, OFF-state open-load detection, short-to-VCC immunity, and CMOS-compatible 3 V/5 V input logic compatibility across -40°C to 150°C junction temperature.
Technical Context
The device implements two independent VIPower® M0-7 high-side power switches with integrated current-limiting, thermal shutdown, and undervoltage protection. Each channel features programmable latch-off behavior triggered by overtemperature or power limitation events, controlled via dedicated FaultRST pin.
MultiSense functionality uses a single analog output pin multiplexed across three diagnostic modes-load current sense (proportional mirror), VCC monitoring, and TCHIP temperature-with SEL0/SEL1 addressing and SEn enable control. All diagnostics operate with ±5% full-scale accuracy and support OFF-state open-load detection at >100 kΩ threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage Range | 4 V to 28 V DC - supports full automotive battery range including cold-crank (4 V) and load-dump (28 V) conditions. |
| On-State Resistance (per Ch) | 22 mΩ typ. at 25°C - enables low conduction loss (<0.2 W at 3 A), minimizing thermal stress in compact PCB layouts. |
| Current Limitation | 63 A typ. - provides robust short-circuit protection without external fusing for P27W lamp loads (≈8 A peak). |
| Standby Current | 0.5 µA max. - ensures negligible battery drain during vehicle sleep mode, meeting ISO 11898-2 quiescent requirements. |
| MultiSense Accuracy | ±5% full-scale for load current - enables precise real-time load monitoring for predictive fault detection and LED current regulation. |
| Thermal Shutdown Threshold | 150°C junction - triggers configurable latch-off to prevent silicon damage during sustained overload or poor heatsinking. |
| ESD Protection | 4 kV HBM on INPUT/FAULT pins - meets AEC-Q100 Grade 0 requirements for harsh automotive ESD environments. |
Pinout & Package
Package: PowerSSO-16 (exposed die pad, thermally enhanced surface-mount). Pin count: 16 terminals, with 2 power outputs, 2 inputs, 3 diagnostic control signals, 1 multiplexed analog sense output, and dedicated fault reset.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary 12 V rail connection; supports up to 40 V transient clamping per ISO 16750-2. |
| OUTPUT0, OUTPUT1 | High-side power outputs | Switched 12 V outputs driving grounded lamps/LEDs; each rated for 63 A peak current limitation. |
| GND | Ground reference | Must be reverse-battery protected externally; serves as return path for load current and internal bias. |
| INPUT0, INPUT1 | CMOS-compatible control inputs | Accept 3 V/5 V logic; include hysteresis (0.2 V) for noise immunity in automotive harness environments. |
| MultiSense | Multiplexed analog diagnostic output | Delivers proportional current (e.g., 1 mA = 1 A load) or voltage-derived signals; requires external ADC sampling. |
| SEn | Sense enable input | Active-high signal enabling MultiSense function; allows disabling during low-power module sleep. |
| SEL0, SEL1 | Multiplexer address inputs | Select diagnostic mode: 00 = load current, 01 = VCC, 10 = TCHIP; 11 = reserved. |
| FaultRST | Fault reset / latch control | Active-low pin that unlatches outputs after fault or forces auto-restart mode when held low. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel high-side switching | Independent control of two automotive loads with shared diagnostics-reduces BOM count vs. discrete solutions. |
| MultiSense analog feedback | Single-pin multiplexed sensing of load current, supply voltage, and die temperature-eliminates need for separate sensors and ADC channels. |
| Configurable latch-off | FaultRST pin enables system-level decision: hard latch (safe shutdown) or auto-restart (for intermittent faults like bulb filament bounce). |
| OFF-state open-load detection | Identifies disconnected bulbs before activation using >100 kΩ impedance threshold-prevents false fault reporting during module initialization. |
| Reverse battery protection support | Compatible with external GND-line diode/resistor network per Figure 4.1-enables robust design against -14 V transients. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 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 MultiSense analog multiplexing; requires external ADC or MCU with SPI interface. | Preferred when digital diagnostics and lower channel count suffice; not suitable for legacy analog-sensing architectures. |
| VND7E025AJTR-E | Single-channel, 25 mΩ RON, identical MultiSense architecture and pinout compatibility (PowerSSO-16). | Requires two devices for dual-load control; shares same diagnostic protocol and fault handling. | Used when channel independence is critical or layout constraints favor staggered placement over dual-channel integration. |
Compared with TPS4H160-Q1, VND7020AJTR-E offers superior analog diagnostic fidelity and dual-channel integration; versus VND7E025AJTR-E, it reduces component count and PCB area by 50% while maintaining identical thermal and protection behavior per channel.

FAQ
What is the purpose of the FaultRST pin?
The FaultRST pin is an active-low input that controls fault recovery behavior: pulling it low unlatches outputs after overtemperature or overload events, while holding it high enables configurable latch-off. It also supports auto-restart mode when continuously asserted, allowing system-level fault management without MCU intervention.
How does MultiSense distinguish between load current, VCC, and chip temperature?
MultiSense uses SEL0 and SEL1 pins to select one of three diagnostic modes: 00 for load current (1 mA = 1 A), 01 for VCC (1 mA = 1 V), or 10 for TCHIP (1 mA = 1°C). The SEn pin must be high to activate the selected mode, and all signals appear as proportional current on the MultiSense pin for external ADC conversion.
Can VND7020AJTR-E drive inductive loads like solenoids or motors?
Yes-it supports inductive demagnetization energy up to 64 mJ (at VCC = 16 V, Tj = 150°C) and includes active clamp circuitry to limit VOUT overshoot during turn-off. External flyback diodes are not required, but PCB layout must minimize parasitic inductance in the output loop to avoid voltage spikes exceeding 46 V clamp threshold.
Is reverse battery protection built-in or external?
Reverse battery protection is external: the GND pin must be connected through a series diode or resistor network per Figure 4.1 in the datasheet. The device itself withstands -0.3 V on VCC and includes internal negative voltage clamp on OUTPUT pins, but full -14 V reverse battery survival requires external components on the GND path.
