Product details

Overview

VND7040AJTR-E from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-16 package, integrating VIPower® technology for 12 V grounded loads. It delivers 40 mΩ typical on-state resistance per channel, 34 A current limitation, and multiplexed MultiSense analog feedback (load current, VCC, chip temperature) with <0.5 µA standby current. Designed for signal lamp control up to SAE1156/R5W parallel or LED rear combinations.

For engineers reviewing the VND7040AJTR-E datasheet, VND7040AJTR-E pinout, VND7040AJTR-E application, or VND7040AJTR-E equivalent, this page provides verified technical context, diagnostic architecture details, protection behavior under short-to-VCC and off-state open-load conditions, and real-world automotive load interface requirements including reverse battery handling with external diode networks.

Technical Context

The device implements dual independent high-side power switches with integrated current-sense mirroring, thermal shutdown with configurable latch-off, and active power limitation during overload. Its MultiSense pin multiplexes three diagnostics-proportional load current (±5% accuracy), supply voltage (VCC), and junction temperature-via SEL0/SEL1 address lines and SEn enable control.

Protection logic includes undervoltage shutdown (4 V trip, 5 V reset), overvoltage clamp (41 V typ), loss-of-ground/VCC detection, and fast thermal transient self-limiting. FaultRST is an active-low pin enabling auto-restart mode or manual unlatching after thermal or current faults.

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)	40 mΩ typ at 25°C - enables low conduction loss for 2.5 A continuous loads with minimal thermal rise.
Current limitation	34 A typ - limits peak fault current to protect wiring and downstream loads during short-to-ground events.
Standby current	0.5 µA max at 25°C - ensures negligible battery drain in vehicle sleep modes.
MultiSense feedback precision	±5% load current sense accuracy - enables reliable closed-loop current monitoring without external shunt resistors.
Thermal shutdown threshold	150°C junction - triggers latch-off or auto-restart depending on FaultRST state to prevent permanent damage.
Transient supply voltage rating	40 V (ISO 16750-2 Test B clamped) - withstands automotive load-dump transients without external clamping.

Pinout & Package

Package: PowerSSO-16 - thermally enhanced exposed-pad SOIC variant with 0.65 mm pitch, optimized for high-current automotive PCB layouts and JEDEC JESD 51-7 thermal performance (R_thj-amb = 23.5 °C/W on 4-layer board).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary 12 V rail connection; supports 4–28 V operation and clamps transients up to 40 V.
OUTPUT0, OUTPUT1	High-side power outputs	Drive grounded resistive/inductive/capacitive loads; each rated for 34 A peak current limitation.
GND	Ground reference	Must be protected against reverse battery via external diode/resistor network per datasheet Figure 30.
INPUT0, INPUT1	CMOS-compatible control inputs	Accept 3 V/5 V logic; include hysteresis (0.2 V) for noise immunity in harsh automotive environments.
MultiSense	Multiplexed analog diagnostic output	Delivers proportional current for load current, VCC, or T_CHIP; requires external 10 kΩ pull-up for voltage readout.
SEn	Sense enable	Active-high CMOS input; disables MultiSense during module low-power mode or enables sharing across multiple devices.
SEL0, SEL1	Multiplexer address lines	Select diagnostic source: 00 = load current, 01 = VCC, 10 = chip temperature, 11 = reserved.
FaultRST	Fault reset/unlatch control	Active-low input; holds outputs latched during fault unless pulled low to enable auto-restart behavior.

Key Features

Feature	Design Value
Dual-channel high-side switching	Independent control of two 12 V grounded loads with separate INPUT/OUTPUT pairs and shared diagnostics.
MultiSense analog feedback	Single-pin multiplexed sensing of load current (±5% accuracy), supply voltage, and junction temperature - eliminates need for discrete sense components.
Configurable fault latch-off	FaultRST pin allows system-level choice between persistent latch (safe default) or auto-restart mode for transient fault recovery.
Reverse battery protection support	Integrated GND line protection design with external diode (DGND) network - meets ISO 16750-2 requirements without additional ICs.
Low quiescent current	0.5 µA standby current enables compliance with automotive ECU sleep-mode current budgets (<10 µA total).

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 R_ON, no analog current sense - uses digital SPI diagnostics only.	Lacks multiplexed analog feedback; requires external ADC for current/voltage monitoring.	Choose when system already includes SPI-based diagnostics infrastructure and lower channel count suffices.
VND7E025AJTR-E	Single-channel, 25 mΩ R_ON, identical MultiSense architecture and PowerSSO-16 footprint.	Same diagnostic capability but half the channel density; requires two units for dual-load coverage.	Prefer when higher current drive (25 A min) and lower R_ON are critical, and board space allows duplication.

Compared with TPS4H160-Q1, VND7040AJTR-E offers superior analog diagnostic fidelity and dual-channel integration; versus VND7E025AJTR-E, it trades lower on-resistance for higher channel count and slightly relaxed current rating - optimizing for space-constrained multi-lamp modules.

FAQ

What is the purpose of the FaultRST pin?

The FaultRST pin is an active-low control input that determines fault recovery behavior. When held high, thermal or overcurrent faults trigger a latched shutdown until a system-level reset occurs. When pulled low, the device enters auto-restart mode, attempting periodic re-enabling after fault clearance - critical for non-safety-critical loads like interior lighting where temporary interruption is acceptable.

How does MultiSense enable off-state open-load detection?

With SEn high and SEL0/SEL1 set to 11 (reserved), the MultiSense pin outputs a voltage proportional to the off-state output leakage current. If the connected load is disconnected, the resulting current drop falls below the 0.01 µA threshold, triggering a diagnostic flag. This occurs without energizing the load, preserving battery life during vehicle sleep states.

Can VND7040AJTR-E drive inductive loads like solenoids?

Yes - the device integrates active demagnetization energy management and supports maximum switching energy of 36 mJ per pulse (T_DEMAG = 0.4 ms). Its built-in clamp diode (V_F = 0.7 V at -2.5 A, 150°C) safely dissipates inductive kickback, eliminating need for external flyback diodes in most 12 V solenoid applications up to 50 W.

What PCB layout considerations apply to PowerSSO-16?

The PowerSSO-16 package requires a minimum 2 cm² copper pour connected to the exposed pad for thermal performance. On 4-layer boards, use 2s2p JEDEC JESD 51-7 construction to achieve R_thj-amb = 23.5 °C/W. Avoid routing signal traces under the thermal pad; instead, use thermal vias (≥8×0.3 mm) to inner ground planes to maximize heat dissipation to internal layers.
