Product details

Overview

VNQ5160KTR-E from STMicroelectronics is a quad-channel automotive high-side driver IC built on VIPower™ M0-5 technology, designed to control resistive, inductive, or capacitive loads connected to ground. It delivers 5.4 A typical current limiting per channel, 160 mΩ max on-state resistance at 25°C, and operates across 4.5–36 V supply range - used in body control modules for headlight, fog light, and HVAC blower switching.

For engineers reviewing the VNQ5160KTR-E datasheet, VNQ5160KTR-E pinout, VNQ5160KTR-E application, or VNQ5160KTR-E equivalent, key selection criteria include ISO 7637-2 pulse immunity (Class C up to +87 V), dual open-load detection (on/off state), thermal shutdown with auto-restart, and reverse-battery protection compatibility via external GND network design.

Technical Context

This device integrates four independent high-side power switches with embedded diagnostics and protection logic. Each channel features CMOS-compatible 3.0 V input threshold, active inrush current management via power limitation, and status reporting through open-drain STATUS pins controlled by STAT_DIS.

Protection architecture includes undervoltage shutdown (4.5 V trip), output-to-VCC short detection, self-limiting fast thermal transients, and clamp-based overvoltage handling (41 V max transient). Diagnostic functions operate independently per channel with configurable status pin behavior and timing-controlled fault reporting (e.g., tDOL(on) = 200 µs).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	4.5 V to 36 V DC - supports full automotive battery range including cold-crank (4.5 V) and load-dump transients (clamped to 41 V)
Max transient VCC	41 V - withstands ISO 7637-2 Pulse 5b (87 V clamped) when used with external load dump protection
On-state R_ON	160 mΩ max @ 1 A, 25°C - ensures ≤160 mV drop at 1 A, minimizing heat generation in low-power switching
Current limit (typ)	5.4 A @ VCC = 13 V - provides robust overload protection while allowing peak inrush for lamp filaments
Off-state supply current	2 µA @ VCC = 13 V, Tj = 25°C - enables ultra-low quiescent power for always-on vehicle modules
Open-load detection	Active in both ON-state (I_OL = 10–40 mA) and OFF-state (V_OL = 2–4 V) - enables reliable fault reporting without external sensing
Thermal shutdown	150°C trip, 135°C reset - implements safe power cycling during sustained overload without latch-up

Pinout & Package

Package: PowerSSO-24, thermally enhanced exposed-tab surface-mount package with integrated VCC connection to tab. Designed for high-power dissipation in automotive under-hood environments.

Pin/Terminal	Circuit Role	Design Meaning
INPUT1–INPUT4	CMOS-compatible control input	3.0 V logic threshold with 0.25 V hysteresis; drives corresponding OUTPUTn channel
OUTPUT1–OUTPUT4	High-side power output	Drives load between OUTPUTn and GND; includes V_DS clamp and short-to-VCC detection
STATUS1–STATUS4	Open-drain diagnostic output	Reports channel faults (open-load, overtemp, UVLO); disabled when STAT_DIS = high
STAT_DIS	Status disable control	Active-high CMOS input; places all STATUS pins in high-impedance when asserted
VCC	Main supply input	4.5–36 V supply with internal 41 V clamp; connects directly to exposed thermal tab
GND	Power ground reference	Must be protected against reverse battery via external diode/resistor network per Figure 27

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents voltage droop during lamp filament cold-start, eliminating need for external soft-start circuitry
Dual open-load detection	Validates load continuity in both energized (ON) and de-energized (OFF) states - critical for safety-critical lighting and motor control
Reverse battery protection support	Compatible with external GND-line diode/resistor networks (per Figure 27), enabling operation in vehicles with reversed jumper cable risk
ISO 7637-2 Class C immunity	Passes all 5 pulses (including +87 V Pulse 5b with external clamp), meeting OEM EMC requirements without additional TVS components
Thermal shutdown with auto-restart	Re-enables output after fault clears and junction cools to 135°C - avoids system lockout during intermittent overloads

Applications

Automotive Lighting Control

HVAC Blower Motor Drive

Use Scenario: Controlling halogen/filament headlights, fog lights, and parking lamps in modern BCMs.

IC Role / Device Role / Timing Role: High-side switch providing PWM-capable load control with real-time open-load feedback during illumination cycles.

Use Value: Eliminates discrete MOSFET + gate driver + sense resistor solutions; reduces BOM count while maintaining ISO 16750-2 compliance.

Use Scenario: Driving 12 V DC blower motors in climate control systems with variable speed demand.

IC Role / Device Role / Timing Role: Four-channel load driver enabling independent fan stage control (low/med/high/off) with thermal derating awareness.

Use Value: On-chip current limiting (5.4 A) and thermal shutdown prevent motor stall damage; diagnostic outputs feed ECU fault logging.

Seat Heater Activation

Power Window Lift Control

Use Scenario: Switching resistive heating elements in automotive seat heater mats.

IC Role / Device Role / Timing Role: High-side power switch with precise open-load detection to confirm heater element integrity before activation.

Use Value: Detects broken heater traces or connector disconnection in OFF state - preventing false "heater on" indications and improving functional safety.

Use Scenario: Controlling bidirectional DC motors in power window lift mechanisms using H-bridge configuration with two VNQ5160KTR-E devices.

IC Role / Device Role / Timing Role: Dual high-side driver per motor direction, coordinated with external low-side switches and status monitoring.

Use Value: Integrated short-to-VCC detection identifies wiring faults (e.g., crushed harness contacting battery rail), enhancing ASIL-B readiness.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (200 mΩ typ), lower ILIM (4.5 A), no off-state open-load detection	Lacks OFF-state diagnostics; requires external circuitry for full open-load coverage	Preferred where cost sensitivity outweighs diagnostic completeness and thermal performance is less constrained
BTS716G	Single-channel, identical R_ON and ILIM specs, same PowerSSO-24 footprint but only one output	Requires four separate packages for quad functionality - increases PCB area and assembly cost	Used when channel isolation or staggered layout is required; not a drop-in replacement for VNQ5160KTR-E

Compared with TPS4H160-Q1 and BTS716G, the VNQ5160KTR-E uniquely combines quad integration, dual-mode open-load detection, and ISO 7637-2 Class C immunity in a single PowerSSO-24 package - reducing system-level complexity for automotive body electronics.

FAQ

What is the maximum continuous output current per channel?

The VNQ5160KTR-E provides 5.4 A typical current limiting per channel under steady-state conditions at VCC = 13 V and Tj = 25°C. Actual continuous current depends on PCB thermal design and ambient temperature; derating curves in Figure 32 show R_thj-amb vs copper area. At 10 cm² copper, continuous current remains above 3.5 A at 85°C ambient.

How does open-load detection work in the OFF state?

In OFF state, the device monitors output voltage relative to GND. If V_OUT exceeds 2–4 V (depending on VCC), it detects an open load and pulls the corresponding STATUS pin low after a 200–1000 µs delay (t_POL). This works without external pull-ups and is validated down to VCC = 8 V, making it effective during low-battery conditions.

Can STAT_DIS be left floating?

No - Table 3 explicitly states that STAT_DIS must not be left floating. It should be tied to GND via a 10 kΩ resistor if unused, or driven actively high to disable STATUS outputs. Floating STAT_DIS may cause unpredictable status pin behavior due to noise susceptibility and undefined CMOS input state.

Is reverse battery protection built-in?

The VNQ5160KTR-E does not include internal reverse battery protection. As stated in Section 3.1, external GND-line protection (diode or resistor network per Figure 27) is mandatory to prevent damage during reverse polarity events. The device's V_F rating of –0.3 V confirms it cannot tolerate reverse VCC applied directly.
