Product details

Overview

VND7050AJ12TR-E from STMicroelectronics is a double-channel automotive high-side driver in PowerSSO-12 package, delivering 50 mΩ on-resistance per channel, 30 A current limit, and analog CurrentSense feedback with multiplexed diagnostics. It operates from 4 V to 28 V supply, supports deep-cranking down to 2.85 V, and drives grounded resistive/inductive loads such as automotive signal lamps (P27W, SAE1156, LED rear combinations).

For engineers reviewing the VND7050AJ12TR-E datasheet, VND7050AJ12TR-E pinout, VND7050AJ12TR-E application, or VND7050AJ12TR-E equivalent, key selection criteria include cranking voltage margin, analog current sense accuracy, thermal shutdown behavior, and compatibility with 3 V/5 V CMOS logic interfaces in safety-critical body electronics modules.

Technical Context

This device integrates two independent VIPower® high-side switches with embedded protection logic and a shared analog CurrentSense multiplexer. Each channel features active current limitation, thermal shutdown with hysteresis, undervoltage lockout (2.85 V trip), and overvoltage clamping up to 40 V transient.

The CurrentSense pin delivers proportional load current (1:2000 ratio), plus diagnostic flags for short-to-ground, short-to-VCC, off-state open-load, and thermal shutdown - all selectable via SEL and enabled/disabled via SEn. The architecture supports low-power module sleep modes while retaining diagnostic capability.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4 V to 28 V operating; supports engine cranking down to 2.85 V without dropout
R_ON (per channel)	50 mΩ typ. at 2 A/25°C; ensures <100 mV drop at rated load, minimizing power loss
I_LIMH	30 A typ. current limit; self-limiting during overload avoids external fusing
I_STBY	0.5 µA max. at 25°C; enables ultra-low-power sleep states in body control modules
CurrentSense Ratio	1:2000 precision mirror; enables accurate load current monitoring with standard ADC
ESD Rating	4 kV HBM on INPUT/SEn/SEL/OUTPUT pins; meets automotive robustness requirements
Thermal Shutdown	140°C trigger (cranking mode); 150°C nominal; prevents latch-up under sustained overload

Pinout & Package

INPUT0, INPUT1	CMOS-compatible control inputs	Hysteresis-enabled; compatible with 3 V/5 V MCU I/Os; no external pull-up required
CurrentSense	Multiplexed analog diagnostic output	Delivers proportional current (I_LOAD/2000) or fault flag voltages; requires external RC filter
SEn	Sense enable control	Active-high; disables CurrentSense output during standby to reduce system leakage
SEL	Multiplexer address select	Chooses between Channel 0 or Channel 1 current feedback on shared CurrentSense pin

Key Features

Feature	Design Value
Deep-cranking operation	Functional down to 2.85 V VCC decreasing; compliant with LV124 Rev 2013 for cold-start reliability
Integrated current sensing	Analog mirror with ±5% accuracy across -40°C to 150°C; eliminates external shunt and amplifier
Multi-fault diagnostics	Single pin reports overload, short-to-ground, short-to-VCC, open-load (off-state), and thermal shutdown
Low quiescent current	0.5 µA standby current enables >10-year battery life in always-on vehicle modules
Reverse battery resilience	With external Schottky or MOSFET GND network, survives -14 V reverse battery per ISO 16750-2

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (160 mΩ), lower ILIM (10 A), integrated watchdog timer, SPI interface	Requires microcontroller for configuration; better suited for programmable load sequencing	Select when SPI-based diagnostics and configurable timing are prioritized over analog simplicity
BD82001FJ-M	Single-channel only, no CurrentSense, 60 mΩ R_ON, 25 A ILIM, smaller HTSOP-8 package	Lacks multiplexed analog feedback and thermal shutdown reporting	Choose for space-constrained single-load applications where diagnostics are handled externally

Compared with TPS4H160-Q1 and BD82001FJ-M, VND7050AJ12TR-E uniquely combines dual-channel integration, analog CurrentSense with fault multiplexing, and extreme low-voltage cranking tolerance - making it optimal for cost-sensitive, high-reliability automotive lighting and body control nodes requiring minimal MCU overhead.

FAQ

What is the purpose of the SEn pin?

The SEn (Sense Enable) pin is an active-high digital input that controls whether the CurrentSense pin outputs analog load current or enters high-impedance state. When SEn = 0 V, CurrentSense is disabled to reduce system leakage during module sleep; when SEn = 3–5 V, it enables multiplexed diagnostics. This allows shared sense routing across multiple drivers and eliminates need for external analog switches.

How does the device handle reverse battery conditions?

VND7050AJ12TR-E does not internally withstand reverse battery; it requires external protection on the GND line using either a Schottky diode or N-channel MOSFET network as specified in ST Application Note AN4733. With proper external circuitry, the device survives -14 V applied to GND per ISO 16750-2, protecting both the IC and downstream loads from polarity reversal damage.

Can both channels be used simultaneously at full load?

Yes - both channels operate independently and can be driven simultaneously at full 30 A peak load, provided PCB thermal design meets ST's PowerSSO-12 layout guidelines: ≥2 cm² copper pour per channel on 4-layer board, thermal vias under exposed pad, and ambient temperature ≤85°C. Junction temperature must remain below 150°C; derating applies above 100°C ambient.

What diagnostic faults are reported on the CurrentSense pin?

The CurrentSense pin reports five distinct conditions via voltage levels: normal load current (proportional 1:2000), overload/short-to-ground (low voltage), thermal shutdown (mid-level voltage), short-to-VCC (high voltage), and off-state open-load (floating or clamped level). These are selected via SEL and enabled via SEn, allowing MCU ADC sampling without additional comparators or logic.
