STMicroelectronics VNQ600TR-E

Overview

VNQ600TR-E from STMicroelectronics is a quad-channel high-side driver IC designed for automotive and industrial load switching, featuring four independent VIPower M0-3 channels, 35 mΩ typical on-state resistance per channel at 25°C, 25 A DC short-circuit current limit, and proportional analog current sense outputs (K = 4400 ±10% at 5 A). It operates from 5.5 V to 36 V supply and integrates undervoltage/overvoltage shutdown, thermal shutdown, reverse battery protection, and loss-of-ground detection - deployed in engine control units, body electronics, and smart junction boxes.

For engineers reviewing the VNQ600TR-E datasheet, VNQ600TR-E pinout, VNQ600TR-E application, or VNQ600TR-E equivalent, key selection considerations include its SO-28 double-island package thermal performance, CMOS-compatible input logic (VIH = 3.25 V), real-time current sensing accuracy across temperature (±6% drift), and integrated protection coordination for ISO 7637-2 pulse compliance in 12 V/24 V vehicle systems.

Technical Context

The VNQ600TR-E integrates two VND600 dies in a single SO-28 double-island package, enabling independent operation of four high-side switches with dedicated sense paths. Each channel implements active current limiting, thermal foldback with 150°C shutdown and 135°C restart hysteresis, and overvoltage clamping at ~48 V (VCC–48 V during turn-off).

Its protection architecture coordinates multiple fault responses: undervoltage shutdown triggers below 4 V (typ.), overvoltage shutdown activates above 36 V, and loss-of-ground detection forces automatic channel disable when GND pins disconnect. Sense outputs deliver ISENSE = IOUT/K with K ranging 3300–6000 depending on load and temperature, referenced to VCC and usable with 3.9 kΩ or 10 kΩ external resistors.

Key Specifications

Pinout & Package

Package: SO-28 (double island) - thermally optimized for dual-die integration, with separate copper islands for channels 1–2 and 3–4 to enable independent thermal management and higher total power dissipation (6.25 W per island).

FAQ

What is the maximum continuous output current per channel?

The VNQ600TR-E supports 15 A continuous output current per channel under specified thermal conditions (T_lead = 25°C, 6 cm² copper area). Its 25 A DC short-circuit current limit is active during faults but not sustainable continuously; derating is required above 100°C junction temperature per Figure 13 in the datasheet.

How does the current sense output work and what external components are needed?

Each CURRENT SENSE pin delivers I_SENSE = I_OUT/K, where K = 4400 (typ.). A 3.9 kΩ resistor to ground converts this to V_SENSE ≈ 0.5 V per ampere, compatible with most MCU ADCs. The sense output remains functional during overtemperature (V_SENSEH = 5.5 V) to signal fault conditions.

Can VNQ600TR-E drive inductive loads like solenoids or relays?

Yes - it includes active demagnetization energy handling (EMAX = 126 mJ at 13.5 V) and overvoltage clamping during turn-off. For solenoids with L > 6 mH, external freewheeling diodes are recommended per Figure 20 to limit peak clamp voltage and ensure reliable operation within the 48 V clamp limit.

Is VNQ600TR-E still in active production given its 2008 datasheet revision?

Although the latest public datasheet is Rev 10 (Nov 2008), VNQ600TR-E remains actively manufactured and distributed by STMicroelectronics with full AEC-Q100 qualification and automotive PPAP support. ST's official product status page confirms it as "active" with no obsolescence notice issued.
