Product details

Overview

VN7016AJTR from STMicroelectronics is a single-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 16 mΩ on-resistance at 25°C, 77 A current limit, and operates from 4–28 V supply-designed specifically for 12 V headlamp control with CMOS-compatible 3 V/5 V input logic.

For engineers reviewing the VN7016AJTR datasheet, VN7016AJTR pinout, VN7016AJTR application, or VN7016AJTR equivalent, key selection criteria include its latch-off configurable thermal shutdown, reverse-battery protection support via external diode network, multiplexed analog diagnostic capability, and compliance with ISO 7637-2 transient immunity requirements for automotive body electronics.

Technical Context

The VN7016AJTR integrates VIPower® M0-7 technology to combine power switching, real-time diagnostics, and fault management in one monolithic device. Its MultiSense pin multiplexes three analog signals-load current (via proportional current mirror), VCC supply voltage, and TCHIP temperature-using SEL0/SEL1 address lines and SEn enable control.

Protection architecture includes undervoltage shutdown (4 V trip, 0.3 V hysteresis), overvoltage clamp (41–52 V), self-limiting fast thermal transients, and configurable latch-off triggered by overtemperature or power limitation, resettable via active-low FaultRST pin. Standby current remains ≤0.5 µA at 25°C.

Key Specifications

T_j Range	−40 to +150 °C junction temp; qualified for under-hood automotive environments

Pinout & Package

Package: PowerSSO-16 (exposed thermal pad, surface-mount, JEDEC MS-012 variant with enhanced thermal performance).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail connection; clamped to 40 V transient; requires reverse-battery protection network
OUTPUT	Power output (pins 9–16 internally connected)	High-side switched output; must be externally tied together on PCB for current sharing and thermal distribution
GND	Ground reference	Return path for control and power stages; requires external diode/resistor network for reverse-battery immunity
INPUT	CMOS-compatible enable input	Hysteresis-enabled digital input; accepts 3 V or 5 V logic; controls ON/OFF state of output switch
MultiSense	Multiplexed analog diagnostic output	Current-mode output delivering proportional I_LOAD, V_CC, or T_CHIP; requires external resistor for voltage conversion
SEn	Sense enable control	Active-high signal enabling MultiSense function; allows OFF-state diagnosis disable during low-power modes
SEL0, SEL1	Multiplexer address inputs	Select diagnostic channel (00 = I_LOAD, 01 = V_CC, 10 = T_CHIP, 11 = reserved)
FaultRST	Fault reset / latch control	Active-low pin; unlatches output after fault or forces auto-restart mode when held low

Key Features

Feature	Design Value
MultiSense analog feedback	Single-pin multiplexed sensing of load current (±5% accuracy), supply voltage, and die temperature-reduces BOM count and PCB routing complexity
Configurable latch-off	FaultRST pin enables either manual reset or auto-restart behavior after thermal or overload shutdown-supports fail-safe or continuous-operation system strategies
Ultra-low standby current	≤0.5 µA at 25°C ensures compliance with automotive ISO 16750-2 sleep-mode leakage budgets
VIPower® M0-7 integration	Monolithic high-voltage BC-DMOS process delivers robust 40 V transient tolerance and integrated clamp protection without external components
Reverse battery readiness	Supports reverse-battery protection using external diode/resistor network on GND line-meets OEM-level robustness requirements

Applications

Automotive Headlamps

Front Fog Lamps

Use Scenario: High-intensity discharge (HID) or LED headlamp modules requiring PWM dimming, open-load detection, and thermal derating feedback.

IC Role / Device Role / Timing Role: Smart high-side switch providing current-controlled drive, real-time thermal monitoring, and short-to-VCC/open-load diagnostics.

Use Value: Enables adaptive beam control via precise load current feedback and prevents thermal runaway during extended high-beam operation.

Use Scenario: Fog lamp circuits exposed to moisture, vibration, and frequent on/off cycling in harsh environmental conditions.

IC Role / Device Role / Timing Role: Fault-tolerant power switch with OFF-state open-load detection and short-to-ground indication during startup.

Use Value: Eliminates need for separate current-sense shunts and discrete protection ICs-reducing board area and validation effort.

Engine Bay Cooling Fans

Body Control Module Loads

Use Scenario: 12 V DC brushless or brushed cooling fans subject to inductive kickback and thermal stress near engine block.

IC Role / Device Role / Timing Role: High-side driver with demagnetization energy handling (88 mJ @ 16 V) and self-limiting thermal response.

Use Value: Sustains reliable operation during rapid fan speed changes while suppressing voltage spikes via internal clamp.

Use Scenario: Centralized power distribution for door locks, mirrors, and interior lighting controlled by BCM microcontroller.

IC Role / Device Role / Timing Role: Low-quiescent, multi-diagnostic switch supporting CAN/FlexRay-based fault reporting via MultiSense analog interface.

Use Value: Provides deterministic fault classification (short-to-VCC vs. open-load) without adding serial communication overhead.

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	Higher R_ON (25 mΩ), no analog current sense-uses digital SPI diagnostics instead of MultiSense	Requires MCU with SPI interface; lacks proportional analog output for direct ADC sampling	Prefer when digital diagnostics and configurability outweigh analog simplicity and cost
BD7F200GUL	Lower current limit (40 A), no thermal shutdown latch-off; only basic overcurrent flag	Missing chip temperature sensing and VCC monitoring-limits system-level health awareness	Choose only for non-critical loads where full diagnostic coverage is not required

Compared with TPS4H160-Q1 and BD7F200GUL, VN7016AJTR uniquely combines ultra-low standby current, multiplexed analog diagnostics on one pin, and configurable latch-off-making it optimal for headlamp and BCM applications demanding precision, reliability, and minimal external components.

FAQ

What is the purpose of the FaultRST pin?

The FaultRST pin is an active-low input that controls fault recovery behavior. When pulsed low, it unlatches the output after thermal or overload shutdown. If held continuously low, it forces auto-restart mode-allowing repeated attempts to re-enable the output without external intervention. This dual-mode functionality supports both fail-safe and mission-critical system architectures.

How does MultiSense deliver three different measurements on one pin?

MultiSense uses internal analog multiplexing controlled by SEL0 and SEL1 address pins. With SEn enabled, the pin outputs a proportional current: 1 mA per amp of load current (I_LOAD), 1 mA per volt of V_CC, or 1 mA per 10°C of chip temperature (T_CHIP). External circuitry converts this current to voltage for MCU ADC sampling, reducing pin count and routing complexity.

Can VN7016AJTR drive inductive loads like cooling fans?

Yes-VN7016AJTR supports inductive loads with up to 88 mJ maximum demagnetization energy at VCC = 16 V. Its internal clamp structure and fast thermal response prevent destructive voltage spikes during turn-off. Application Note AN4712 details recommended snubber design and PCB copper area for optimal thermal dissipation in fan drive configurations.

Is reverse battery protection built-in or external?

Reverse battery protection is external: the GND pin must be connected through a diode/resistor network as specified in Section 4.1 of the datasheet. The device itself tolerates −0.3 V on VCC and includes ESD protection (4 kV HBM), but does not integrate reverse-polarity blocking-requiring careful layout per ST's recommended GND protection topology to meet OEM requirements.
