Product details

Overview

VN5T016AHTR-E from STMicroelectronics is a single-channel automotive high-side driver IC with integrated analog current sense, designed for 24 V systems driving resistive/inductive/capacitive loads grounded on one side. It features 16 mΩ typical on-state resistance at 25 °C, 60 A typical current limitation, AEC-Q100 qualification, and fault reporting via proportional current sense pin (CS). Used in LED lighting control, body electronics, and solenoid actuation.

For engineers reviewing the VN5T016AHTR-E datasheet, VN5T016AHTR-E pinout, VN5T016AHTR-E application, or VN5T016AHTR-E equivalent, key selection criteria include its 8–36 V operating range, thermal shutdown latch-off behavior, FR_Stby reset functionality, and ±2 µA off-state supply current - critical for low-power automotive subsystems requiring diagnostic feedback and robust transient protection.

Technical Context

This device implements ST's VIPower M0-7 technology to integrate power MOSFET, protection logic, and analog current sensing in a single HPAK package. Its active clamp limits VCC transients to 58 V, while internal power limitation dynamically restricts output current during overload without external components.

The analog current sense (CS) delivers a proportional output current across six calibrated ranges (K0–K6), enabling precise load monitoring from 100 mA to 20 A. Fault detection includes off-state open-load, short-to-VCC, thermal shutdown latch-off, and undervoltage lockout - all reported through CS or status latching controlled by FR_Stby.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating voltage	8–36 V DC: Supports full automotive battery range including cold-crank (8 V) and load-dump surges (36 V).
On-state resistance	16 mΩ typ. @ 25 °C: Enables <25 mV drop at 1.5 A, minimizing conduction loss in high-current loads.
Current limit	60 A typ.: Self-limiting protection prevents destructive overcurrent during short-circuit events.
Supply current (off)	2 µA typ.: Ultra-low standby consumption enables always-on modules without battery drain.
Thermal shutdown	150 °C trigger: Latches off until FR_Stby pulse resets; prevents thermal runaway in enclosed environments.
Current sense ratio	K6 = 4240 typ. @ 20 A: Delivers ~4.7 mA CS output for 20 A load, compatible with standard 3.9 kΩ sense resistors.
ESD rating (HBM)	4000 V on IN/FR_Stby pins: Ensures robustness against handling and board-level ESD in assembly lines.

Pinout & Package

Delivered in HPAK package (7 mm × 6.4 mm, 1.1 mm height), thermally optimized with exposed die pad for PCB copper heat sinking. Thermal resistance junction-to-case is 1.5 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Clamped to 58 V max; accepts ISO 7637-2 Pulse 1 (−450 V) and Pulse 5b (+174 V) with external clamp.
OUT	High-side power output	Drives load between OUT and GND; supports inductive demagnetization energy up to 390 mJ.
GND	Power and signal reference	Common return for load, logic, and sense paths; reverse-battery protected via internal MOSFET switch.
IN	CMOS-compatible enable input	Hysteresis of 0.25 V prevents noise-induced switching; 0.9 V low / 2.1 V high thresholds ensure MCU compatibility.
CS	Analog current sense output	Sinks proportional current (I_SENSE) for real-time load monitoring and fault reporting (e.g., 9–12 mA in overload).
FR_Stby	Fault reset & standby control	Pulse-low resets latch-off; sustained low disables outputs and enters ultra-low-power standby mode.

Key Features

Feature	Design Value
Proportional current sense with multi-range calibration	Six K-ratios (K0–K6) cover 100 mA–20 A with <±50% total drift over −40 to +150 °C for LED dimming accuracy.
Integrated reverse-battery protection	Self-switching Power MOSFET blocks −32 V reverse supply without external diode, reducing BOM count and footprint.
Off-state open-load detection	Detects >2 V at OUT when IN = 0 V, enabling bulb-out diagnostics in lighting modules without extra circuitry.
Output short-to-VCC detection	Identifies stuck-high faults within 180–1800 µs, preventing false ON states in safety-critical actuators.
AEC-Q100 Grade 0 qualification	Rated for −40 to +150 °C operation with 100% production test coverage, meeting automotive ASIL-B system requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160BQPWPRQ1	Higher R_ON (25 mΩ), no analog current sense - uses digital SPI reporting.	Lacks continuous analog I_SENSE; requires MCU with SPI interface and firmware for diagnostics.	Preferred where digital bus integration outweighs need for analog simplicity and lower latency.
IPS1035H	Lower current limit (35 A), no FR_Stby pin - auto-restarts after thermal shutdown.	No manual reset capability; unsuitable for fail-safe systems requiring operator confirmation before restart.	Select when automatic recovery is acceptable and peak load current remains below 35 A.

Compared with TPS4H160BQPWPRQ1 and IPS1035H, VN5T016AHTR-E uniquely combines analog current sensing with latch-off reset via FR_Stby and 60 A protection - making it optimal for safety-aware 24 V automotive loads requiring deterministic fault handling and minimal MCU resource usage.

FAQ

What is the purpose of the FR_Stby pin?

The FR_Stby pin serves dual functions: a low-pulse resets latch-off conditions (overload or thermal shutdown), while a sustained low level places the device in ultra-low-power standby mode (<2 µA). It replaces external reset circuitry and enables coordinated system-level fault recovery in multi-channel modules.

How does the current sense (CS) pin report faults?

The CS pin sinks current proportional to load current under normal operation. During faults - such as overload, thermal shutdown, or off-state open-load - it delivers fixed high-current levels (9–12 mA) or voltage clamps (8 V), enabling unambiguous detection without additional comparators or ADC scaling.

Can VN5T016AHTR-E drive inductive loads without external flyback diodes?

No external flyback diode is required due to integrated active demagnetization clamp. When OUT turns off, the device clamps V_OUT to V_CC − 58 V, safely dissipating inductive energy. Maximum safe demagnetization energy is 390 mJ at 32 V and 150 °C start junction temperature.

Is VN5T016AHTR-E compatible with 3.3 V microcontrollers?

Yes. Its IN pin has CMOS-compatible thresholds (V_IL = 0.9 V, V_IH = 2.1 V) and 0.25 V hysteresis, ensuring reliable switching with 3.3 V GPIOs. Input leakage is ≤1 µA, eliminating need for pull-up resistors in most configurations.
