STMicroelectronics VNQ600A13TR

Overview

VNQ600A13TR from STMicroelectronics is a quad-channel high-side solid-state relay (HSD) in SO-28 double-island package, designed for automotive and industrial load switching with ground-referenced loads. It delivers 25 A DC short-circuit current per channel, features CMOS-compatible inputs, proportional analog current sense outputs (K = 3300–6000 A/A), and integrated protections including thermal shutdown (150°C), overvoltage clamp (41–55 V), undervoltage lockout (4 V typ), reverse battery protection, and loss-of-ground detection. Used in body control modules for driving lamps, solenoids, and actuators.

For engineers reviewing the VNQ600A13TR datasheet, VNQ600A13TR pinout, VNQ600A13TR application, or VNQ600A13TR equivalent, key selection criteria include per-channel R_DS(on) (35 mΩ @ 25°C), current sense accuracy (±10% drift over -40°C to +150°C), dual-chip thermal isolation in SO-28, ISO 7637-2 pulse immunity (Class C), and compliance with automotive-grade transient requirements.

Technical Context

The VNQ600A integrates two independent VND600 monolithic high-side drivers fabricated in ST's VIPower M0-3 technology, each handling two channels - resulting in four fully isolated output stages with dedicated sense paths. Each channel implements active current limiting, demagnetization control for inductive loads, and independent thermal monitoring with hysteresis (15°C).

Protection logic is hardware-based and autonomous: undervoltage (V_USD = 4 V) and overvoltage (V_OV = 36 V) shutdowns disable outputs without microcontroller intervention; reverse battery events trigger internal clamping; and ground disconnection causes immediate channel disable via dedicated GND1,2/GND3,4 pins. Sense outputs remain functional during overtemperature events, delivering fixed 5 V (V_SENSEH) for fault reporting.

FAQ

What is the maximum continuous output current per channel?

The VNQ600A13TR supports 15 A continuous output current per channel at T_lead = 25°C with adequate PCB copper (0.5 cm² per island). Derating applies above 25°C ambient: R_thj-amb = 46°C/W for two channels ON, limiting usable current to ~8 A at 85°C ambient with standard FR-4 layout.

How does the current sense output behave during thermal shutdown?

During thermal shutdown (T_j ≥ 150°C), the current sense pin transitions to a fixed 5 V output (V_SENSEH) regardless of load current, providing unambiguous fault indication to the host controller without requiring additional comparators or logic.

Can VNQ600A13TR drive inductive loads like solenoids safely?

Yes - it integrates active demagnetization control per channel, clamps flyback voltage to 41–55 V, and limits peak demagnetization energy to 126 mJ (L = 0.11 mH, I_L = 40 A). External freewheeling diodes are unnecessary, reducing BOM count and board space.

Is reverse battery protection implemented internally or externally?

Reverse battery protection is internal and automatic: the device blocks reverse current flow when V_CC < 0 V, with absolute maximum rating of -0.3 V. No external diode or resistor is required for basic protection, though ST recommends optional ground-line diode (DGND) for enhanced robustness in severe reverse-polarity scenarios.
