Product details

Overview

VN9016AJTR from STMicroelectronics is a single-channel automotive smart high-side driver in PowerSSO-16 package, designed for 12 V grounded loads with CMOS-compatible 3 V/5 V control. It delivers 16 mΩ on-state resistance, 50.6 A current limitation (typ.), and <0.5 µA standby current, enabling deep cold-cranking operation per LV124 Rev 2013 in ADAS radar and sensor power supply applications.

For engineers reviewing the VN9016AJTR datasheet, VN9016AJTR pinout, VN9016AJTR application, or VN9016AJTR equivalent, this page provides verified technical context, diagnostic multiplexing behavior, thermal latch-off configuration, reverse-battery protection implementation, and real-world load-current sensing accuracy across temperature and voltage ranges.

Technical Context

The device integrates VIPower M0-9 technology to combine power MOSFET switching with analog current-sense feedback, undervoltage/overvoltage clamping, and dynamic thermal transient limiting. Its fault management relies on ΔTJ-based power limitation (not just TJ threshold) and configurable latch-off via active-low FaultRST pin.

Diagnostic functionality centers on the CS pin: a multiplexed analog output delivering proportional load current (K = 8390 ±7% at 3.7 A), chip temperature sense, supply voltage feedback, and discrete fault states (open-load, short-to-VCC, short-to-ground) - all enabled by SEn and decoded via external resistor network.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4–28 V operating; supports deep cold cranking down to 2.7 V undervoltage shutdown reset.
R_ON	16 mΩ typ. at 3.7 A, 25 °C; rises to 35.2 mΩ at 150 °C - directly impacts conduction loss in high-current loads.
I_LIMH	50.6 A typ. DC short-circuit current limit at 16 V, -40 °C; enables robust overload handling without external fusing.
I_STBY	0.5 µA max. at 13 V, 25 °C - ensures ultra-low quiescent draw critical for always-on automotive modules.
CS Accuracy	±7% current sense ratio (K) at 3.7 A; ±10% drift over -40 to 150 °C - enables reliable closed-loop load monitoring.
t_{D_Restart}	50–75 ms latch-OFF delay before auto-restart - prevents rapid cycling during persistent faults while allowing recovery after transient events.
TTSD	150–210 °C thermal shutdown trigger - protects against sustained overtemperature with 7 °C hysteresis (TRS = 135 °C).

Pinout & Package

Package: PowerSSO-16 (exposed thermal pad connected to VCC). Surface-mount package optimized for high-power dissipation in automotive under-hood environments.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; connects to exposed thermal tab; supports clamp up to 36 V and reverse-battery tolerance via internal diode path.
GND	Ground reference	Must be externally reverse-battery protected; serves as return for logic and power stages.
INPUT0	CMOS-compatible enable input	Hysteresis-enabled (0.2 V), 3 V/5 V compatible; controls channel ON/OFF state with low leakage (<1 µA).
OUTPUT0	High-side power output	Drives grounded loads; features integrated clamp diode (V_F = 0.7 V at -3.7 A, 150 °C) and fast turn-on/off (10–120 µs).
CS	Multiplexed analog sense output	Delivers I_SENSE ∝ I_OUT (K ≈ 8390); also encodes V_CC, die temperature, and fault status based on SEn timing and external R_SENSE.
SEn	Sense enable control	Active-high CMOS input; enables CS output; must be pulled to 5 V for diagnostics; floating not allowed.
FaultRST	Fault reset/latch control	Active-low; sets auto-restart (pulled low) or latch-off (pulled high); unlatches output in <20 µs.

Key Features

Feature	Design Value
Extreme low-voltage operation	Functional down to 2.7 V V_CC (LV124-compliant), enabling reliable start-stop and cold-crank performance.
Integrated reverse-battery protection	Self-turn-on prevention via internal architecture; no external diode required on VCC line - reduces BOM count and footprint.
Multiplexed analog diagnostics	Single CS pin delivers load current, supply voltage, junction temperature, and 4 fault types - cuts wiring and ADC channel requirements.
Configurable thermal response	FaultRST pin selects between auto-restart (transient overload recovery) or latch-off (persistent fault isolation) modes.
AEC-Q100 qualified	Grade 0 (-40 to +150 °C), qualified per stress test standard - validated for engine bay and ADAS ECU deployment.

Applications

IC Role / Device Role / Timing Role: High-side switch with current-sense feedback and thermal foldback, ensuring stable power during EMI-rich RF transmission bursts.

Use Value: Prevents system-level shutdown during radar pulse-induced thermal transients via ΔTJ-based power limitation instead of fixed TJ shutdown.

Use Scenario: Driving image sensor power rails in surround-view camera ECUs exposed to wide ambient temperature swings.

IC Role / Device Role / Timing Role: Smart load switch with OFF-state open-load detection and short-to-VCC immunity - critical for verifying sensor cable integrity pre-boot.

Use Value: Enables automated cable health check at startup using CS pin voltage thresholds, eliminating need for external test circuitry.

Engine Control Unit (ECU) Actuator Driver

Body Control Module (BCM) Lighting Load

Use Scenario: Controlling fuel injector solenoids and idle air control valves in gasoline direct injection systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side driver with analog current sense applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS7004-1EPP	4-channel, 14 mΩ R_ON, no multiplexed CS - separate pins for current sense and fault flags.	Lacks integrated V_CC/temperature sensing on CS; requires more PCB routing and MCU GPIOs.	Preferred when multi-channel consolidation outweighs diagnostic richness and board space is constrained.
NXP MC33883A	Single-channel, 25 mΩ R_ON, 30 A ILIM, analog current sense but no thermal hysteresis or latch-off configuration.	No FaultRST-controlled mode selection; fixed auto-restart only - less flexible for safety-critical latch requirements.	Selected where simpler fault behavior suffices and lower R_ON is not required for thermal budget.

Compared with BTS7004-1EPP and MC33883A, VN9016AJTR offers superior diagnostic integration (single-pin multiplexing), deeper cold-crank capability (2.7 V), and user-configurable fault response - making it optimal for next-gen ADAS power domains demanding both intelligence and resilience.

FAQ

What is the function of the CS pin and how is it used in practice?

The CS pin is a multiplexed analog output delivering load current (I_OUT/K), supply voltage (V_CC), and junction temperature - plus fault states like open-load or short-to-VCC. In practice, an external 0.7–10 kΩ pull-down resistor converts I_SENSE to measurable voltage; timing of SEn pulses selects the sensed parameter, enabling full diagnostics with one ADC channel and minimal external components.

How does the FaultRST pin affect thermal fault behavior?

FaultRST configures the device's response to thermal overload: when held low, it enables auto-restart mode (output cycles on/off with thermal hysteresis); when held high, it forces latch-off (output stays off until manually reset). This dual-mode behavior is implemented internally - no software or external timer needed - and resets occur within 20 µs of FaultRST transition.

Can VN9016AJTR drive inductive loads without external flyback protection?

Yes - VN9016AJTR integrates a V_DEMAG clamp that limits turn-off voltage to V_CC − 36 V (min) during inductive energy release. This eliminates the need for external TVS diodes in most 12 V automotive inductive applications (e.g., solenoids, relays), provided layout minimizes parasitic inductance and thermal design accommodates W_OFF losses (0.25–0.55 mJ).

Is reverse-battery protection fully integrated, or does it require external components?

Reverse-battery protection is architecturally integrated: the device prevents self-turn-on during reverse polarity via internal gate control, and GND must be externally protected (e.g., with series diode/resistor network) per datasheet guidance. No external reverse-polarity MOSFET or diode on the VCC line is required - reducing bill-of-materials and improving reliability in compact modules.
