Product details

Overview

VNQ5E160AKTR-E from STMicroelectronics is a quad-channel automotive high-side driver in PowerSSO-24 package, delivering 160 mΩ on-resistance per channel, 10 A typical current limit, and analog current sense with ±12% ratio drift over temperature. It drives 12 V grounded resistive/inductive/capacitive loads with integrated diagnostics including open-load detection, short-to-VCC diagnosis, and thermal shutdown indication.

For engineers reviewing the VNQ5E160AKTR-E datasheet, VNQ5E160AKTR-E pinout, VNQ5E160AKTR-E application, or VNQ5E160AKTR-E equivalent, this device supports precise load monitoring in body control modules, LED lighting systems, and smart junction boxes where CMOS-compatible 3.0 V/5.0 V microcontroller interfacing and fault-aware power switching are required.

Technical Context

The device implements four independent VIPower M0-5 high-side switches with active power limitation for inrush and overload management, coupled with dedicated analog current sense pins (CS1–CS4) providing proportional output current feedback. Each channel features input hysteresis, undervoltage lockout at 4.5 V, and overvoltage clamp up to 52 V.

Diagnostic logic enables simultaneous off-state open-load detection, short-to-VCC identification, and thermal shutdown indication via status signaling. The CS_DIS pin allows global disable of all current sense outputs to share external sense resistors across multiple devices - critical for space-constrained automotive PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands automotive load-dump transients without external clamping
Operating voltage range	4.5 V to 28 V - supports cold-crank (4.5 V) and boosted battery (28 V) conditions
On-state resistance (per ch.)	160 mΩ @ 25°C - limits conduction loss to ≤250 mW at 1 A, enabling compact thermal design
Current limitation (typ)	10 A - provides robust short-circuit protection while sustaining >1 A continuous load at 150°C junction
Off-state supply current	2 µA - ensures <10 µA total system standby draw when all channels inactive
Current sense accuracy	±12% full-scale ratio drift - enables reliable fault thresholding across -40°C to 150°C ambient
Input compatibility	3.0 V CMOS - interfaces directly with low-voltage MCUs without level-shifting circuitry

Pinout & Package

Package: PowerSSO-24 - thermally enhanced exposed-tab SO-24 variant with integrated VCC connection to heatsink pad; optimized for automotive under-hood thermal environments (R_thj-case = 8 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; connects internally to exposed thermal pad for low-impedance heat path
GND	Ground reference	Reverse-battery protected node requiring external diode/resistor network per Figure 32
INPUT1–INPUT4	Digital control inputs	CMOS-compatible with 2.1 V VIH and 0.9 V VIL; include 0.25 V hysteresis for noise immunity
OUTPUT1–OUTPUT4	High-side switched outputs	Drive grounded loads; each features active clamp (V_clamp = 46 V typ) and fast demagnetization support
CURRENT SENSE1–4	Analog diagnostic outputs	Deliver I_OUT/K current proportional to load (K = 330–870); enable real-time fault classification
CS_DIS	Global current sense enable	Active-high CMOS input; disables all CS pins when pulled ≥2.1 V, allowing shared external resistor

Key Features

Feature	Design Value
Inrush current active management	Power limitation architecture dynamically caps peak current during capacitive load turn-on, preventing fuse blow and bus droop
Proportional analog current sense	Four independent CS pins deliver linear 0–5 V output across 25 mA–1.5 A load range, enabling software-based load profiling
Off-state open-load detection	Validates load continuity with <5 mA threshold and <300 µs response - detects broken wires before system startup
Thermal shutdown with auto-restart	Shuts down at 150°C junction and resumes after cooling to 135°C, maintaining functionality during intermittent overload
Reverse battery protection	Withstands -0.3 V reverse V_CC and integrates GND protection network interface (Figure 32), eliminating need for external series diodes

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VNQ5E050AKTR-E	50 mΩ R_ON, 20 A I_LIMH, same package and pinout	Better suited for high-current motors or heaters; higher conduction loss at low load	Select when peak load exceeds 10 A and thermal margin permits higher dissipation
TPS4H160-Q1	Single-channel, 160 mΩ, SPI-configurable diagnostics, QFN-24	Requires external MCU for multi-channel coordination; lacks analog CS outputs	Prefer when programmable fault thresholds or daisy-chain configuration is needed over analog simplicity

Compared with VNQ5E160AKTR-E, the VNQ5E050AKTR-E offers lower on-resistance but reduced thermal headroom per channel, while the TPS4H160-Q1 trades analog current sense for digital configurability and single-channel isolation - making the VNQ5E160AKTR-E optimal for cost-sensitive, analog-diagnostic-focused quad-load applications.

FAQ

What is the maximum operating junction temperature for VNQ5E160AKTR-E?

The device is rated for continuous operation up to 150°C junction temperature, with thermal shutdown activation at 150°C (typical) and automatic restart once junction cools to 135°C. This enables deployment in engine bay locations without forced air cooling, provided PCB copper area meets Figure 36 thermal guidelines.

Can VNQ5E160AKTR-E drive inductive loads like fuel injectors or solenoids?

Yes - it supports inductive loads with built-in demagnetization energy handling (34 mJ max per pulse at 13.5 V) and active voltage clamping (46 V typical). The V_ON output voltage drop limiter ensures controlled turn-off, and the 10 A current limit prevents destructive flyback currents during rapid de-energization.

How does the CS_DIS pin affect current sense functionality?

Pulling CS_DIS high (>2.1 V) disables all four CURRENT SENSE outputs simultaneously, placing them in high-impedance state. This allows sharing of a single external sense resistor among multiple VNQ5E160AKTR-E devices - reducing component count and improving layout symmetry in multi-channel systems.

Is VNQ5E160AKTR-E compliant with automotive electromagnetic compatibility standards?

Yes - it meets stringent automotive EMC requirements per ISO 11452-2 (radiated immunity), ISO 11452-4 (BCI), and ISO 7637-2 (transient immunity), with verified low electromagnetic emissions and high immunity due to optimized internal layout and integrated filtering structures.
