Product details

Overview

VND7050AJTR-E from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-16 package, featuring MultiSense analog feedback for load current (±5% accuracy), supply voltage, and chip temperature sensing. It delivers 50 mΩ typical on-resistance per channel, 30 A current limitation, and operates across 4–28 V supply with <0.5 µA standby current - designed specifically for LED and filament rear lamp control in 12 V vehicle systems.

For engineers reviewing the VND7050AJTR-E datasheet, VND7050AJTR-E pinout, VND7050AJTR-E application, or VND7050AJTR-E equivalent, key selection criteria include AEC-Q100 qualification, configurable latch-off fault recovery via FaultRST, multiplexed analog diagnostics, reverse battery protection support, and compatibility with 3 V/5 V CMOS microcontroller interfaces.

Technical Context

The device integrates two independent VIPower® M0-7 high-side switches with embedded power limitation, thermal shutdown, and undervoltage lockout. Each channel supports fast transient response with turn-on delay <1.5 µs and features dedicated logic inputs (INPUT0/1) with hysteresis for noise immunity in harsh automotive environments.

MultiSense functionality uses a single analog output pin to sequentially report load current (via proportional current mirror), VCC supply level, and TCHIP temperature - all selectable via SEL0/SEL1 address lines and enabled by SEn. Fault detection includes short-to-VCC, OFF-state open-load, and thermal overload with configurable latch behavior controlled by FaultRST.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	4–28 V DC - supports full automotive battery range including cold-crank (4 V) and load-dump (28 V)
On-resistance (per channel)	50 mΩ typ. at 25°C - enables low conduction loss and minimal self-heating at 10 A continuous
Current limitation	30 A typ. - provides robust short-circuit protection without external current-sense resistor
Standby current	0.5 µA max. at 25°C - ensures negligible battery drain during vehicle sleep mode
MultiSense accuracy	±5% load current sense - enables precise closed-loop lamp brightness control and fault thresholding
AEC-Q100 grade	Grade 0 (−40°C to +150°C junction) - qualified for under-hood and headlamp module placement
Fault recovery	Configurable latch-off with active-low FaultRST - allows either manual reset or auto-restart mode selection

Pinout & Package

Package: PowerSSO-16 (exposed die pad, thermally enhanced SO-16 variant with GND-connected heatsink tab).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary 12 V rail connection; clamped to 40 V transient; feeds internal regulators and power stage
GND	Power ground reference	Must be reverse-battery protected externally; connects to exposed thermal pad for PCB heat dissipation
OUTPUT0 / OUTPUT1	High-side switched outputs	Drive grounded loads (e.g., lamps, solenoids); each internally limited to 30 A peak and thermally protected
INPUT0 / INPUT1	CMOS-compatible control inputs	Accept 3 V/5 V logic; include hysteresis for EMC robustness; directly interface MCU GPIOs without level shifters
MultiSense	Multiplexed analog diagnostic output	Delivers proportional current for I_LOAD, V_CC, or T_CHIP; requires external 10 kΩ pull-up to VCC for voltage-mode readout
SEn	Sense enable control	Active-high signal enabling MultiSense output; allows disabling diagnostics during low-power modes or shared-sense configurations
SEL0 / SEL1	Multiplexer address inputs	Select diagnostic source: 00 = I_LOAD, 01 = V_CC, 10 = T_CHIP, 11 = reserved
FaultRST	Fault reset/latch control	Active-low input; latched faults clear only when pulsed low; held low → auto-restart mode

Key Features

Feature	Design Value
MultiSense analog feedback	Single-pin multiplexed reporting of load current, supply voltage, and chip temperature - eliminates need for separate ADC channels or external sensors
Configurable fault latch	FaultRST pin enables system-level choice between manual reset (pulse) or auto-restart (held low) after overtemperature or overload events
Reverse battery protection ready	Supports external diode/resistor network on GND line - meets ISO 16750-2 requirements without internal series FETs
Ultra-low standby consumption	0.5 µA max. at 25°C - extends vehicle battery life during extended parking with modules powered
Integrated power limitation	Self-limiting thermal response during fast transients - avoids destructive energy accumulation during inductive load switching

Applications

Automotive Rear Combination Lamps

LED Headlamp Beam Switching

Use Scenario: Driving P27W incandescent bulbs and multi-segment LED arrays in SAE1156-compliant rear lamp modules.

IC Role / Device Role / Timing Role: Dual high-side switch controlling brake/tail/turn functions with synchronized diagnostics and thermal management.

Use Value: Enables single-chip replacement of discrete MOSFETs + sense resistors + protection ICs while meeting E-mark and AEC-Q100 requirements.

Use Scenario: Dynamic high-beam LED matrix control requiring individual segment enable/disable with real-time current monitoring.

IC Role / Device Role / Timing Role: Precision current-regulated high-side driver with ±5% analog sense for adaptive beam shaping and fault isolation.

Use Value: Eliminates need for external current-sense amplifiers and reduces BOM count by 4 components per channel versus discrete solutions.

Engine Bay Solenoid Control

Body Control Module Load Management

Use Scenario: Driving fuel injector solenoids and HVAC actuators in high-temperature under-hood locations.

IC Role / Device Role / Timing Role: Robust high-side driver with 150°C junction rating, fast turn-on (<1.5 µs), and integrated demagnetization energy handling.

Use Value: Withstands 125°C ambient with derated R_thj-amb = 25°C/W on 4-layer PCB - enables compact placement near engine ECUs.

Use Scenario: Centralized power distribution for door locks, mirrors, and interior lighting in modern BCM architectures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel automotive high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (100 mΩ), no analog current sense - uses digital SPI diagnostics instead of MultiSense	Lacks proportional current mirror; requires external ADC or microcontroller with SPI interface for diagnostics	Preferred when system already uses SPI-based diagnostics and lower cost outweighs analog sensing capability
BTS7040-2EPP	Single-channel, identical PowerSSO-16 footprint; shares same VIPower M0-7 process and MultiSense architecture	Requires two devices for dual-channel function; increases PCB area and BOM count vs. integrated dual-channel	Used when channel independence or staggered thermal profiles justify separate packages

Compared with TPS4H160-Q1 and BTS7040-2EPP, VND7050AJTR-E uniquely combines dual-channel integration, ±5% analog current sensing on one pin, and sub-1 µA standby - making it optimal for space-constrained, low-power automotive lamp modules where analog diagnostic fidelity is critical.

FAQ

What is the maximum transient voltage the VND7050AJTR-E can withstand?

The device supports up to 40 V transient supply voltage per ISO 16750-2 Test B (clamped), with internal overvoltage clamp activating at 41–52 V depending on junction temperature. This protects against load-dump events without requiring external TVS diodes in most standard 12 V vehicle designs.

How does the MultiSense pin deliver three different measurements on one terminal?

MultiSense uses time-multiplexed current-mode output: SEL0/SEL1 select between load current (I_OUT × 1/200), V_CC (scaled 1:10), or T_CHIP (10 µA/°C). An external 10 kΩ pull-up converts current to voltage; timing is controlled by SEn pulse width and SEL state transitions per Figure 7 and Figure 8 in the datasheet.

Can VND7050AJTR-E drive inductive loads like fuel injectors safely?

Yes - it includes integrated demagnetization energy handling (EMAX = 30 mJ at T_jstart = 150°C) and fast thermal limiting. When driving inductive loads, external freewheeling paths must be implemented per Figure 35, and PCB copper area must meet JEDEC JESD51-7 thermal guidelines to sustain repetitive switching.

Is reverse battery protection built-in or external?

Reverse battery protection is external: the GND pin must be connected through an external diode/resistor network as shown in Figure 36. The device itself lacks internal reverse-polarity FETs but tolerates −0.3 V on VCC and includes ESD protection (4 kV HBM) on all pins to survive induced transients.
