Product details
Overview
VNQ5050KTR-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 19 A typical current limiting per channel, 50 mΩ max on-state resistance at 25°C, and operates across 4.5–36 V supply range - enabling robust load switching in engine control units, body electronics, and lighting modules.
For engineers reviewing the VNQ5050KTR-E datasheet, VNQ5050KTR-E pinout, VNQ5050KTR-E application, or VNQ5050KTR-E equivalent, key selection criteria include ISO 7637-2 transient immunity (Pulses 1, 2a, 3a/b, 4, 5b), dual open-load detection (on/off-state), thermal shutdown with auto-restart, reverse battery protection support, and CMOS-compatible 3.0 V logic inputs.
Technical Context
The device integrates four independent high-side power switches with embedded protection and diagnostics. Each channel features active current limitation, undervoltage/overvoltage clamping, and self-limiting thermal response - with shutdown triggered at 150°C and automatic recovery after cooling to ≥135°C.
Diagnostic functionality includes open-drain STATUS pins per channel, controlled via STAT_DIS, enabling real-time fault reporting for open-load (on/off), output short-to-VCC, and overtemperature events - all synchronized with precise timing delays (e.g., tDOL(on) = 200 μs, tSDL = 20 μs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max supply voltage | 41 V - withstands load dump transients up to ISO 7637-2 Pulse 5b (87 V peak, 400 ms) |
| Operating voltage range | 4.5 to 36 V - supports full automotive battery range including cold-crank (4.5 V) and alternator regulation (up to 36 V) |
| On-state resistance (per ch.) | 50 mΩ max at 25°C - limits conduction loss to ≤200 mW at 2 A, enabling compact thermal design |
| Current limitation (typ) | 19 A - sustains short-circuit conditions without external fusing while limiting power dissipation |
| Off-state supply current | 2 µA - enables always-on systems (e.g., door modules) with negligible battery drain |
| Open-load detection | On-state: 10–70 mA threshold; Off-state: 2–4 V threshold - detects disconnected loads under active and idle conditions |
| Thermal shutdown | 150°C trigger with 135°C reset - provides fail-safe operation and automatic recovery without MCU intervention |
Pinout & Package
Package: PowerSSO-24 (exposed thermal pad, VCC-connected tab), surface-mount, RoHS-compliant ECOPACK® package optimized for automotive PCB thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INPUT1–4 | CMOS-compatible logic input | 3.0 V compatible with microcontroller GPIO; 0.25 V hysteresis prevents noise-induced toggling |
| OUTPUT1–4 | High-side power output | Drives grounded loads; integrated clamp diode handles inductive kickback (VDEMAG = VCC−41 V) |
| STATUS1–4 | Open-drain diagnostic output | Reports faults (open-load, overtemp); pulled low during fault unless STAT_DIS = high (Hi-Z mode) |
| STAT_DIS | Status disable control | Active-high CMOS input; disables all STATUS pins simultaneously to reduce system-level I/O count |
| VCC | Main supply input | 41 V absolute max; internal clamp protects against ISO 7637 transients; connects to exposed thermal tab |
| GND | Power ground reference | Must be protected externally against reverse battery (diode/resistor network per Fig. 27) |
Key Features
| Feature | Design Value |
|---|---|
| Inrush current management | Active power limitation during turn-on prevents fuse blowing and voltage droop in shared rail systems |
| EMI-optimized switching | Controlled dV/dt and integrated clamp reduce radiated emissions - meets automotive EMC requirements without added snubbers |
| Dual open-load detection | Validates load integrity both when powered (on-state) and unpowered (off-state), critical for safety-critical lighting and valve control |
| Reverse battery protection support | External GND-line protection network (resistor or diode) enables operation down to −14 V without damage |
| ISO 7637-2 compliance | Passes Class C immunity for all pulses (1, 2a, 3a/b, 4, 5b) - validated per manufacturer test data, not requiring external TVS |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel automotive high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Higher RON (160 mΩ), lower ILIM (1.6 A), integrated SPI interface, no off-state open-load detection | Better suited for low-power digital loads (e.g., sensors, small relays); lacks analog-level fault granularity | Select when system requires programmable diagnostics and SPI-based configuration over analog STATUS pins |
| BTS716G | Single-channel, 12 mΩ RON, 43 A ILIM, identical PowerSSO-12 package, no STAT_DIS pin | Requires four devices for quad functionality; superior thermal performance but higher BOM count and layout area | Select when maximum current capability per channel (>30 A) and minimal RON dominate over integration and diagnostics |
Compared with VNQ5050KTR-E, TPS4H160-Q1 trades analog diagnostic fidelity for digital configurability and smaller footprint, while BTS716G offers higher single-channel performance at the cost of reduced integration and increased PCB routing complexity.

FAQ
What is the purpose of the STAT_DIS pin?
The STAT_DIS pin is an active-high CMOS input that places all four STATUS outputs into high-impedance state when driven high. This allows sharing of a single pull-up resistor and microcontroller input across multiple channels, reducing system-level I/O count and simplifying fault monitoring architecture without disabling diagnostics entirely.
How does the VNQ5050KTR-E handle inductive load demagnetization?
The device integrates an internal clamp circuit that limits the output voltage during turn-off to VCC−41 V (min) under 2 A load current, safely dissipating demagnetization energy up to 104 mJ per pulse. This eliminates the need for external flyback diodes in most automotive inductive applications like solenoids and relays.
Can the VNQ5050KTR-E operate with a 3.3 V microcontroller?
Yes - its INPUT pins are fully 3.0 V CMOS-compatible with VIH = 2.1 V (min) and VIL = 0.9 V (max), ensuring reliable interfacing with standard 3.3 V MCUs. Input hysteresis of 0.25 V further enhances noise immunity in electrically noisy automotive environments.
Is reverse battery protection built-in or external?
Reverse battery protection is implemented externally via a GND-line network (resistor or diode) as specified in the application schematic (page 19). The IC itself tolerates −0.3 V on VCC and includes ESD protection (4 kV HBM), but sustained reverse polarity must be blocked upstream to prevent latch-up or damage.
