STMicroelectronics VNQ690SP13TR

Overview

VNQ690SP13TR from STMicroelectronics is a quad-channel high-side solid-state relay IC designed for driving resistive or inductive loads with one side grounded in automotive and industrial power distribution systems. It features 90 mΩ on-resistance per channel, 10 A continuous output current, 36 V supply voltage rating, integrated thermal shutdown, and CMOS-compatible inputs. Used in body control modules for lamp/valve actuation where load diagnostics and robust fault protection are required.

For engineers reviewing the VNQ690SP13TR datasheet, VNQ690SP13TR pinout, VNQ690SP13TR application, or VNQ690SP13TR equivalent, key selection criteria include per-channel current limiting (10 A), open-load detection threshold (1.5–3.5 V), undervoltage/overvoltage shutdown thresholds (4.6 V / 36 V), and PowerSO-10 thermal performance under pulsed inductive switching.

Technical Context

The VNQ690SP13TR integrates four independent VIPower M0-3 high-side switches with embedded protection logic including thermal shutdown (trip at 150 °C), overcurrent limiting (10–20 A depending on temperature), and off-state open-load detection via status pin voltage monitoring. Each channel operates with CMOS-level input control (VIH = 3.25 V, VIL = 1.25 V) and provides diagnostic feedback through a shared open-drain status pin.

It implements reverse-battery protection via internal clamp diodes and supports load-dump transient immunity per ISO 7637-2 Pulse 5 (up to +86.5 V). The device uses a single VCC supply (6–36 V) and requires no external flyback components for inductive demagnetization-output clamping activates at VCC − 41 V during turn-off.

FAQ

What is the maximum safe inductive load energy the VNQ690SP13TR can handle during turn-off?

The VNQ690SP13TR safely clamps demagnetization energy up to 53 mJ under defined test conditions (L = 0.38 mH, V_bat = 13.5 V, I_L = 14 A, T_jstart = 150 °C). This is achieved via internal VCC-referenced clamp diodes that limit output voltage to VCC − 41 V, eliminating need for external snubbers in most automotive solenoid applications.

How does the STATUS pin indicate an open-load condition?

The STATUS pin goes low when any channel detects an open-load condition - defined as output voltage exceeding 1.5–3.5 V while the corresponding INPUT is high and VCC is within operating range. This occurs because the internal current source pulls the STATUS node low when no load current flows and the output floats above the VOL threshold, enabling immediate MCU fault response without polling.

Can VNQ690SP13TR be used with a 5 V logic controller directly?

Yes - its CMOS-compatible inputs accept VIH = 3.25 V (min) and VIL = 1.25 V (max), making it fully compatible with standard 5 V microcontrollers. Input hysteresis of 0.5 V ensures noise immunity, and input clamp voltage limits (±0.7 V to 8 V) protect against transient overshoot without external series resistors.

Is the PowerSO-10 package RoHS-compliant and halogen-free?

Yes - the VNQ690SP13TR uses ST's ECOPACK® PowerSO-10 package, certified RoHS-compliant and halogen-free per IEC 61249-2-21. The package features matte tin lead finish, Pb-free solder compatibility, and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for standard SMT assembly processes.
