Product details

Overview

VN5E016AHTR-E from STMicroelectronics is a single-channel 16 mΩ automotive high-side driver in HPak package, featuring analog current sense, power-limiting overload protection, and CMOS-compatible 3 V/5 V input control. It delivers up to 73 A short-circuit current limit, operates from 4.5 V to 28 V supply, and supports diagnostics including ON/OFF-state open-load detection and thermal shutdown with auto-restart - used for driving 12 V grounded resistive/inductive/capacitive loads such as headlights and HVAC actuators.

For engineers reviewing the VN5E016AHTR-E datasheet, VN5E016AHTR-E pinout, VN5E016AHTR-E application, or VN5E016AHTR-E equivalent, key selection criteria include on-resistance (16 mΩ typ.), current sense accuracy across 0.25–25 A, fault indication timing (e.g., 270–600 µs INPUT-to-ISENSE delay), and compliance with automotive transients (load dump, reverse battery).

Technical Context

The device integrates VIPower™ M0-5 technology to combine vertical power MOSFET switching with smart protection logic. Its active power limitation dynamically manages inrush and overload by regulating output voltage drop (VON ≤ 25 mV at 0.5 A) and clamping overvoltage (41–52 V), while maintaining precise thermal response via junction temperature monitoring (TTSD = 150–200 °C).

Diagnostics are implemented through a dedicated CURRENT SENSE pin delivering proportional IOUT/ISENSE ratios (K0 = 2950–9400) with drift < ±11% over –40 °C to 150 °C, and CS_DIS pin enabling shared external sense resistor usage. Fault reporting includes separate signals for short-to-VCC, off-state open-load, and thermal shutdown - all compatible with standard microcontroller GPIOs.

Key Specifications

Parameter	Value and Actual Design Meaning
RON (typ)	16 mΩ at 5 A, 25 °C - enables low conduction loss and minimal self-heating under nominal load
ILIMH (typ)	73 A at VCC = 13 V - defines maximum sustained short-circuit current before active power limitation engages
VCC Range	4.5 V to 28 V - supports full automotive battery range including cold-crank (4.5 V) and load-dump (28 V)
IS (off-state)	2 µA typical - ensures negligible quiescent current for always-on modules like body controllers
IOUT/ISENSE Ratio	4540–6490 (K1 @ 5 A) - provides scalable analog current feedback for MCU ADC with < ±11% drift over temperature
TTSD	150 °C shutdown threshold - triggers thermal protection before silicon damage, with auto-restart at TR ≈ 135–140 °C
dVOUT/dt (on/off)	0.2 V/µs - controls EMI during switching and prevents false triggering of downstream circuits

Pinout & Package

Package: HPak - thermally enhanced surface-mount package with exposed drain pad for low R_thj-case (0.63 °C/W), optimized for automotive PCB layouts requiring high power density and thermal reliability.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Connects to 12 V vehicle battery rail; supports 41 V absolute max and reverse-battery protection
OUTPUT	High-side switched output	Drives grounded loads; pins 1 and 7 internally tied - must be externally connected per layout guidelines
GND	Power ground reference	Provides return path for load current and internal logic; critical for accurate current sense and EMI performance
INPUT	CMOS-compatible control input	Accepts 3 V/5 V logic levels with hysteresis (0.25 V); drives internal gate driver to turn OUTPUT on/off
CURRENT SENSE	Analog diagnostic output	Sinks proportional current (ISENSE) for external resistor-to-voltage conversion; supports real-time load monitoring
CS_DIS	Current sense enable/disable	Active-high CMOS input; disables CURRENT SENSE when pulled high, enabling shared sense resistor across multiple channels

Key Features

Feature	Design Value
Inrush current management	Active power limitation limits peak current during capacitive load turn-on, preventing fuse blow and voltage sag
Proportional analog current sense	Factory-trimmed IOUT/ISENSE ratio with < ±4% drift at 25 A enables high-fidelity load monitoring without calibration
Off-state open-load detection	Validates load continuity before activation - critical for safety-critical lighting and valve control systems
Reverse battery protection	Integrated GND network withstands –14 V reverse polarity without external diode, reducing BOM count
Overtemperature auto-restart	Thermal shutdown releases after cooldown (TR ≈ 135–140 °C), restoring function without MCU intervention

Applications

Automotive HVAC Actuator

Use Scenario: Controlling door locks, window lifts, and mirror adjusters with shared diagnostic bus.

IC Role / Device Role / Timing Role: Single-channel high-side driver with CS_DIS pin enabling multiplexed current sense across 8+ outputs using one ADC channel.

Use Value: Cuts PCB area and cost by 40% vs discrete sense solutions; maintains ±5% current measurement accuracy across channels.

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 RON (20 mΩ), no analog current sense - uses digital SPI diagnostics only	Lacks proportional ISENSE output; requires external ADC or SPI interface for current data	Preferred when system already uses SPI-based diagnostics and thermal budget allows +25% conduction loss
VNQ5E016AJTR-E	Quad-channel version with identical per-channel specs (16 mΩ, 73 A ILIMH), same HPak package footprint	Enables consolidation of four independent loads (e.g., interior lights) into single IC; shares VCC/GND pins	Select when board space is constrained and ≥2 high-side outputs are needed - reduces component count by 75% vs discrete singles

Compared with VN5E016AHTR-E, TPS4H160-Q1 trades analog diagnostics for digital configurability and higher integration, while VNQ5E016AJTR-E offers identical per-channel performance in quad form - making it ideal for multi-output modules where footprint and thermal coupling are design priorities.

FAQ

What is the maximum continuous output current rating for VN5E016AHTR-E?

The device does not specify a fixed continuous current rating due to thermal dependence. At T_j = 25 °C with adequate heatsinking (R_thj-amb ≤ 20 °C/W), it supports >10 A continuous; at 150 °C ambient with R_thj-amb = 69.3 °C/W, derating limits practical continuous current to ~3.5 A. Designers must use thermal simulation with actual PCB copper area and airflow.

How does the current sense disable (CS_DIS) function affect diagnostic capability?

When CS_DIS is pulled high, the CURRENT SENSE pin is disabled - halting ISENSE output and disabling all analog-based diagnostics (ON/OFF open-load, overload indication). However, digital fault flags (thermal shutdown, short-to-VCC) remain active on the OUTPUT pin. This mode enables shared external sense resistors across multiple VN5E016AHTR-E devices without signal crosstalk.

Can VN5E016AHTR-E drive inductive loads like fuel injectors without external flyback protection?

No external flyback diode is required. The device integrates an active clamp circuit that limits V_DEMAG to V_CC – 41 V during inductive turn-off, safely dissipating demagnetization energy. Tested up to 350 mJ per pulse (L = 1.55 mH, V_bat = 13.5 V), it meets ISO 7637-2 Pulse 5a requirements without added components.

What is the recommended PCB layout practice for the HPak package's exposed drain pad?

The exposed drain pad (pins 1 and 7) must be soldered to a minimum 200 mm² copper pour with ≥4 thermal vias (0.3 mm diameter, 0.8 mm pitch) connecting to inner ground planes. This achieves R_thj-amb ≈ 35 °C/W in standard 4-layer boards - critical to sustain 73 A short-circuit current without exceeding 150 °C junction temperature within 10 ms.
