STMicroelectronics VNQ810P-E

Overview

VNQ810P-E from STMicroelectronics is a quad-channel automotive-grade high-side driver IC built using VIPower™ M0-3 technology, designed to drive grounded loads in 12 V/24 V vehicle electrical systems. It features 160 mΩ on-state resistance per channel, 3.5 A continuous output current, 36 V operating supply voltage, and integrated open-load detection (on/off-state), thermal shutdown, overvoltage clamp, and reverse battery protection. It is used in body control modules for controlling lamps, solenoids, and actuators.

For engineers reviewing the VNQ810P-E datasheet, VNQ810P-E pinout, VNQ810P-E application, or VNQ810P-E equivalent, key selection considerations include per-channel current limiting (3.5 A), dual-island SO-28 thermal performance, ISO 7637-2 transient immunity (Class C up to Pulse 5), CMOS-compatible input logic, and diagnostic status pin functionality per channel.

Technical Context

The VNQ810P-E integrates two independent VND810P-E dies in a single SO-28 double-island package, enabling four fully isolated high-side switch channels with individual input, output, and status pins. Each channel implements active current limiting, thermal foldback with hysteresis (TTSD = 150–200 °C, TR = 135 °C), and bidirectional open-load detection using internal current sensing and voltage thresholding (VOL = 1.5–3.5 V off-state).

It incorporates an active VCC clamp for load-dump protection (ISO 7637-2 Pulse 5 compliant), undervoltage lockout (VUSD = 3–5.5 V), overvoltage shutdown (VOV = 36 V), and reverse-battery protection via internal diode clamping (VF ≤ 0.6 V at −0.5 A, Tj = 150 °C). Status pins provide real-time fault reporting including overload, overtemperature, open-load, and overvoltage conditions.

Key Specifications

Pinout & Package

Package: SO-28 (double island), thermally enhanced with two electrically isolated islands - each island hosts two channels with dedicated VCC/GND pairs to minimize thermal crosstalk and support independent power domain routing.

FAQ

What is the maximum continuous output current per channel?

The VNQ810P-E supports 3.5 A continuous output current per channel at T_j ≤ 150 °C with adequate PCB copper area (≥6 cm² per island). Derating applies above 25 °C ambient: I_LIM decreases to ~5 A at 125 °C case temperature per Figure 14, and thermal shutdown activates at 150–200 °C junction temperature.

How does the device handle reverse battery connection?

The VNQ810P-E includes monolithic reverse-battery protection via integrated clamp diodes between VCC and OUTPUT pins, limiting forward voltage to ≤0.6 V at −0.5 A and 150 °C. This eliminates the need for external series diodes while maintaining full functionality during −12 V battery misconnection.

Can unused INPUT and STATUS pins be left floating?

No - Table 2 specifies that unused INPUT pins must be tied to ground via a 10 kΩ resistor or directly to GND, and unused STATUS pins require external pull-up resistors. Floating inputs risk undefined logic states and increased EMI susceptibility; floating STATUS pins prevent accurate fault reporting and may cause false diagnostics.

What is the purpose of the double-island SO-28 package?

The double-island SO-28 physically and thermally isolates the four channels into two groups (channels 1–2 and 3–4), each with dedicated VCC/GND pairs. This architecture minimizes thermal crosstalk, enables independent power domain routing, improves fault containment, and supports higher total power dissipation (2 × 6.25 W) than conventional single-island packages.
