Product details
Overview
VNI8200XP-32 from STMicroelectronics is an octal high-side smart power solid-state relay with selectable SPI/parallel interface, designed for industrial I/O control. It delivers 1.0 A per channel (vs. 0.7 A in VNI8200XP), operates from 10.5–36 V, integrates a 100 mA adjustable DC-DC regulator, and features per-channel overload/overtemperature protection plus loss-of-GND detection - deployed in programmable logic controllers driving solenoids, valves, and indicator lamps.
For engineers reviewing the VNI8200XP-32 datasheet, VNI8200XP-32 pinout, VNI8200XP-32 application, or VNI8200XP-32 equivalent, key selection considerations include its dual-mode interface (SPI up to 5 MHz or parallel), integrated LED matrix driver (4×2), fast demagnetization clamp (VOUT clamped to VCC−45 V), PowerSSO-36 thermal performance (Rth(JC) = 0.7 °C/W), and IEC61131-2 compliance for industrial PLC environments.
Technical Context
The VNI8200XP-32 implements eight independent VIPower™ high-side switches with active current limiting (1.0 A typ.) and channel-specific thermal shutdown (TTSD = 160–180 °C). Its embedded buck regulator (400 kHz, 100 mA) supplies VREG at 3.3 V or 5 V via FB pin configuration and includes boot diode integration on PHASE/BOOT pins.
SPI mode enables daisy-chaining, MCU freeze detection via WD pin, and extended diagnostics (SPI fault, case overtemperature, Power Good) encoded in 8- or 16-bit frames with parity check. Parallel mode uses direct IN1–IN8 logic inputs with OUT_EN global enable, while dedicated open-drain FAULT, TWARN, and PG pins report aggregated or channel-specific faults with pull-up to VREG.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 10.5 V to 36 V - supports wide industrial supply rails including 24 V nominal systems with brown-out margin. |
| Output Current (per channel) | 1.0 A continuous - enables driving higher-power solenoids, relays, and LED arrays without external boost. |
| RDS(on) | 0.11 Ω @ 25 °C - minimizes conduction loss (≤2.5 W/channel at 1 A) and thermal stress in PowerSSO-36 package. |
| SPI Clock Frequency | Up to 5 MHz - allows real-time output updates and diagnostic reads within <2 µs frame time (16-bit). |
| Thermal Shutdown Threshold | Junction: 160–180 °C; Case: 115–155 °C - provides layered protection against sustained overload or ambient overheating. |
| DC-DC Output | Adjustable 3.3 V or 5 V (via FB divider) - powers VREG, LED matrix, and external isolators without secondary LDO. |
| Demagnetization Clamp | VOUT clamped to VCC−45 V - safely dissipates inductive kickback energy (up to 3 J/channel) during turn-off. |
| UVLO Hysteresis | 0.5 V - prevents oscillation near 10 V threshold during supply sag, ensuring clean startup/shutdown sequencing. |
Pinout & Package
Package: PowerSSO-36 (10.3 × 10.3 mm, exposed tab connected to VCC), optimized for high-power density and thermal dissipation in industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1–OUT8 | High-side power outputs | Drive loads referenced to GND; each independently protected against overload, short-circuit, and overtemperature. |
| SEL2, SEL1/IN1–SDO/IN8 | Interface mode & data/control pins | SEL2 = H selects SPI (5 MHz); SEL2 = L enables parallel mode; INx pins double as channel controls in parallel mode. |
| FAULT, TWARN, PG | Open-drain diagnostic outputs | Active-low reporting of junction overtemp (FAULT), case overtemp (TWARN), and VCC undervoltage (PG); pulled up to VREG. |
| VREG, DCVDD, VREF, FB | DC-DC regulator interface | VREG = regulated logic supply; DCVDD/VREF = internal DC-DC outputs; FB sets output voltage via external resistor divider. |
| PHASE, BOOT | Buck converter power stage | PHASE = switch source node; BOOT = bootstrap capacitor connection for high-side gate drive - requires external 100 nF ceramic. |
| ROW0–ROW3, COL0–COL1 | LED matrix drivers | 4-row × 2-column open-drain/source array drives 8 status LEDs (2 per output) with 780 Hz refresh and 25% duty cycle. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-interface flexibility | SPI (5 MHz, 8/16-bit, daisy-chain capable) or parallel (direct IN1–IN8 control) - simplifies migration between microcontroller architectures. |
| Integrated diagnostics | Three dedicated open-drain pins (FAULT, TWARN, PG) deliver real-time fault classification without software polling overhead. |
| Self-contained power management | On-chip 100 mA buck regulator eliminates need for external DC-DC or LDO - reduces BOM count and layout area in space-constrained PLC modules. |
| Inductive load optimization | VOUT clamp to VCC−45 V + fast turn-off (td(OFF) = 10 µs) - suppresses voltage spikes >60 V across 1 mH coils without snubbers. |
| Robust ground integrity monitoring | Loss-of-GND protection forces all outputs OFF if GND path opens - prevents uncontrolled load activation in field-wiring faults. |
Applications
| Programmable Logic Controller (PLC) Output Module | Industrial PC Peripheral I/O Card |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side smart power driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPS2050H | Single-channel, 2.8 A rated, no integrated DC-DC or LED matrix; SPI-only interface. | Used where per-channel current >1.0 A is required but multi-channel integration is not needed. | Select when scaling to higher-current individual loads without needing 8-channel consolidation. |
| VNQ5E160K-E | Quad-channel, 1.6 A/channel, no SPI interface; parallel-only with basic diagnostics (FAULT only). | Deployed in cost-sensitive automotive body control modules with simpler communication needs. | Choose for lower channel count, higher per-channel current, and automotive qualification (AEC-Q100 Grade 1). |
Compared with IPS2050H and VNQ5E160K-E, the VNI8200XP-32 uniquely combines 8-channel integration, dual SPI/parallel interface, on-chip DC-DC, and full LED matrix - making it optimal for space-constrained industrial I/O modules requiring diagnostic richness and supply independence.

FAQ
What is the difference between VNI8200XP and VNI8200XP-32?
The VNI8200XP-32 provides 1.0 A continuous output current per channel versus 0.7 A for the VNI8200XP. Both share identical pinout, package, interface options, and protection features, but the -32 variant uses enhanced current-limiting circuitry to sustain higher load currents without derating at elevated temperatures.
Can the integrated DC-DC regulator supply external components?
Yes - the 100 mA DC-DC output (DCVDD) can power VREG and additional circuitry such as digital isolators or optocouplers. When configured for 3.3 V or 5 V via FB pin, it maintains regulation across full load (0–100 mA) and input range (10.5–36 V), eliminating need for external regulators in most I/O module designs.
How does the watchdog function operate in SPI mode?
In SPI mode, the watchdog is enabled by applying >25% of VREG to WD_EN. The internal timer resets on falling edges of the WD pin. Timeout duration is set by WD_EN voltage level (see Table 13 in DS11044), and expiry forces all outputs OFF until reset via WD pulse or VCC cycle - preventing MCU lockup-induced unsafe states.
Is the PowerSSO-36 package compatible with standard reflow profiles?
Yes - the PowerSSO-36 package is qualified for lead-free reflow per JEDEC J-STD-020. Its exposed VCC-connected tab requires solder paste stencil design with 70–80% aperture ratio and thermal relief vias to inner ground/power planes to ensure reliable thermal transfer and mechanical anchoring during assembly.
