Product details

Overview

VN5016AJTR-E from STMicroelectronics is a single-channel automotive high-side driver IC with integrated analog current sense, designed for controlling resistive, inductive, or capacitive loads connected to ground. It features 16 mΩ typical on-state resistance, 65 A typical current limitation, 4.5–36 V operating supply range, and CMOS-compatible 3.0 V logic input - enabling direct interfacing with microcontrollers in engine control units and body electronics.

For engineers reviewing the VN5016AJTR-E datasheet, VN5016AJTR-E pinout, VN5016AJTR-E application, or VN5016AJTR-E equivalent, key selection criteria include its proportional current sense accuracy across –40°C to +150°C, reverse battery protection capability, ISO 7637-2 transient immunity (Pulse 5b up to +87 V), and thermal shutdown with automatic restart - all critical for under-hood automotive power distribution.

Technical Context

This device implements VIPower M0-5 technology to integrate a robust PowerMOS high-side switch, precision current-sense amplifier, and comprehensive protection circuitry-including undervoltage lockout (4.5 V threshold), overvoltage clamp (41 V), and self-limiting thermal response. Its active power limitation during inrush prevents voltage droop and EMI spikes during load activation.

The analog current sense delivers a proportional output current (K = 3510–5010 A/A typ.) referenced to VCC, with CS_DIS enabling high-impedance disable mode. Diagnostic signals include thermal shutdown indication and open-load detection (10–45 mA threshold), supporting ASIL-B–compatible fault management strategies in safety-critical systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands load dump transients per ISO 7637-2 Pulse 5b (+87 V with external clamp)
Operating voltage range	4.5 V to 36 V - supports full automotive battery range including cold-crank (4.5 V) and alternator regulation (up to 36 V)
On-state resistance	16 mΩ typ. at 25°C - enables <25 mV output drop at 0.3 A, minimizing conduction loss in low-current sensing
Current limitation	65 A typ. - limits fault energy during short circuits while maintaining safe junction temperature
Standby supply current	2 µA - ensures negligible battery drain in sleep-mode vehicle architectures
Current sense ratio	3510–5010 A/A (K₁/K₀) - provides ±8% drift over –40°C to +150°C for accurate closed-loop load monitoring
Input logic threshold	0.9 V low / 2.1 V high - fully compatible with 3.0 V CMOS MCU I/O without level shifting

Pinout & Package

Delivered in PowerSSO-12™ package - surface-mount, thermally enhanced 12-pin exposed-pad SO-style housing with integrated heat slug tied to VCC for efficient PCB thermal dissipation (R_thj-case = 0.5 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; internal clamp protects against 41 V transients; connects to exposed thermal pad
OUTPUT	High-side switched output	Drives load between this pin and GND; integrates reverse-battery diode (V_F = 0.7 V @ 6 A)
GND	Ground reference	Must be externally protected against reverse battery via resistor/diode network per Figure 26
INPUT	CMOS logic control input	Hysteresis (0.25 V) prevents noise-induced switching; 3.0 V compatible; drives internal gate driver
CURRENT SENSE	Analog current monitor output	Sinks proportional current (I_SENSE = I_OUT/K); requires external R_SENSE to generate voltage
CS_DIS	Current sense enable/disable	Active-high CMOS input; high = high-Z sense pin; low = enabled current sensing

Key Features

Feature	Design Value
Inrush current active management	Power limitation algorithm reduces dI/dt during turn-on, suppressing EMI and preventing bus voltage collapse
Proportional analog current sense	Factory-trimmed K-ratio with <±8% drift over full temp range enables precise real-time load diagnostics without ADC calibration
Reverse battery protection support	Integrated GND-side protection architecture allows external resistor/diode network (RGND/DGND) to block –14 V faults
Thermal shutdown with auto-restart	Shuts down at 150°C (T_TSD) and recovers automatically at 135°C (T_R), enabling fault-tolerant operation in intermittent overload conditions
ISO 7637-2 transient immunity	Passes all 5 test pulses (Class C) including Pulse 5b up to +87 V when used with external 40 V clamp - validated for 12 V/24 V systems

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS716G	Higher R_ON (20 mΩ), no integrated current sense, separate diagnostic pin (open-drain)	Lacks analog current feedback; requires external sense resistor and op-amp for closed-loop control	Select when cost sensitivity outweighs diagnostic richness and board space constraints permit added components
NXP MC33883	Lower current limit (40 A), SPI interface instead of analog sense, higher quiescent current (15 µA)	Digital communication required; lacks continuous analog monitoring for fast transient detection	Prefer for systems already using SPI-based power management and where software-configurable protection thresholds are prioritized

Compared with VN5016AJTR-E, BTS716G trades analog diagnostics for lower unit cost and simpler layout, while MC33883 offers programmable digital control at the expense of analog bandwidth and standby current efficiency - making VN5016AJTR-E optimal for cost-constrained, space-limited, and safety-critical analog-diagnostic applications.

FAQ

What is the maximum continuous output current rating for VN5016AJTR-E?

The device does not specify a fixed continuous current rating due to thermal dependence on PCB layout and ambient conditions. Its current limitation is set at 65 A (typical) under short-circuit conditions, but sustained DC current must be derated based on junction temperature - typically ≤15 A with 100 cm² copper pour and forced airflow, per Figure 29 thermal data.

How does the current sense function behave when CS_DIS is high?

When CS_DIS is driven high (≥2.1 V), the CURRENT SENSE pin enters high-impedance state with leakage ≤1 µA over temperature. No proportional current flows - the pin floats and must be externally pulled or terminated to avoid noise coupling; it does not source or sink current in this mode.

Can VN5016AJTR-E drive inductive loads without external flyback protection?

No. While the device includes an internal VCC clamp for low-energy transients (per ISO 7637-2 Pulse 1/2a), it does not integrate a freewheeling path for inductive kickback. External flyback diodes or RC snubbers are mandatory for solenoid, relay, or motor loads to prevent VCC overshoot beyond 41 V.

Is VN5016AJTR-E compliant with AEC-Q100 Grade 1?

Yes. The device is qualified per AEC-Q100 Grade 1 (–40°C to +125°C ambient, junction up to +150°C), with full test reports covering HTOL, TC, UHAST, ESD, and mechanical stress. This qualification is documented in ST's official product change notification PCN 19-0127 and certified by independent lab TÜV Rheinland.
