Product details
Overview
VN380SPTR-E from STMicroelectronics is a monolithic smart solenoid driver and solid-state relay built with VIPower™ technology, designed to control inductive loads such as valves and actuators in industrial automation systems. It delivers up to 7 A load current, features integrated clamps, thermal shutdown, open-coil detection, and a diagnostic output indicating demagnetization or open-load conditions.
For engineers reviewing the VN380SPTR-E datasheet, VN380SPTR-E pinout, VN380SPTR-E application, or VN380SPTR-E equivalent, this device supports precise excitation/recirculation switching for solenoids, offers CMOS-compatible inputs, and provides real-time fault reporting via its active-low diagnostic pin - critical for safety-critical load control and predictive maintenance design.
Technical Context
The VN380SPTR-E integrates two power switches (S1 for excitation, S2 for recirculation) controlled by dual CMOS inputs (A and B), enabling three operational modes: standby, excitation, and recirculation. Its logic implements a truth table where input combinations directly determine switch states and fault response timing.
Protection functions operate autonomously: overcurrent (>15 A) and overvoltage (>27 V) trigger immediate S1 turn-off and forced S2 activation; thermal shutdown activates at 160–200 °C junction temperature; open-load detection triggers at 5–700 mA load current. All protections drive the device into recirculation mode without external intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Load current | Up to 7 A DC - supports high-force solenoids and industrial actuators without external heatsinking under typical ambient conditions. |
| On-resistance (S1) | 0.2 Ω typ. at 5 A - minimizes conduction loss and self-heating during sustained excitation phase. |
| Clamp voltage (Vcl1) | 60–80 V - limits flyback voltage across S1 during demagnetization, protecting against inductive kick damage. |
| Diagnostic output | Active-low open-drain - signals open-load or demagnetization on falling edge of Input B, latched until Input A toggles. |
| Thermal shutdown | 160–200 °C junction threshold - disables S1 and enables S2 to safely dissipate stored coil energy. |
| Input compatibility | CMOS-level (VIL ≤ 1.5 V, VIH ≥ 3.5 V) - interfaces directly with microcontrollers and PLC I/O without level-shifting. |
| Supply voltage (Vpwr1) | 6–24 V - accommodates standard 12 V/24 V industrial control rails with ±20% tolerance. |
Pinout & Package
The VN380SPTR-E is housed in a PowerSO-10 surface-mount package with exposed thermal pad for enhanced heat dissipation. The package meets ECOPACK® environmental compliance standards and is rated for operation from –40 °C to +150 °C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (N.C.) | No connect | Internally unconnected; must be left floating or tied to GND per layout guidelines. |
| 2 (Vpwr1) | Main power supply input | Provides operating voltage (6–24 V) to internal logic and S1 driver stage. |
| 3 (DIAG) | Diagnostic output | Open-drain, active-low signal indicating open-load or demagnetization event. |
| 4 (INPUT B) | Control input B | CMOS-compatible logic input; falling edge triggers DIAG latch and controls S2 activation. |
| 5 (INPUT A) | Control input A | CMOS-compatible logic input; rising edge resets DIAG latch and enables excitation mode. |
| 6,7 (GND) | Ground reference | Dual ground pins reduce impedance and improve noise immunity for power and logic sections. |
| 8 (N.C.) | No connect | Internally unconnected; must be left floating or tied to GND per layout guidelines. |
| 9,10 (Vpwr2) | Recirculation path supply | Provides return path voltage for S2 during demagnetization; internally clamped to 60 V. |
| 11 (LOAD) | Power output terminal | High-side switched output connected to solenoid/load; carries full load current up to 7 A. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated flyback clamping | Vcl1 = 60–80 V and Vcl2 = 24–33 V - eliminates need for external snubbers or TVS diodes in solenoid drive circuits. |
| Demagnetization-mode fast turn-off | Td = 70 µs propagation delay - ensures rapid energy dissipation during valve de-energization, improving response time and reducing mechanical wear. |
| Open-coil detection sensitivity | Iol = 5–700 mA - reliably identifies broken or disconnected solenoids before actuation, preventing system faults. |
| Thermal resistance (junction-to-case) | Rthj-case = 1.67 °C/W - enables direct thermal coupling to PCB copper pour or heatsink for sustained 5 A operation. |
| Truth-table-based mode control | Four defined input states (LL, HH, HL, LH) - simplifies firmware logic and eliminates ambiguity in mode transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart solenoid driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPS1025H | Higher 25 A current rating; single-channel; no dual-Vpwr architecture; uses different diagnostic signaling (push-pull vs open-drain). | Targeted at higher-power industrial actuators; lacks independent Vpwr2 rail for optimized recirculation path control. | Select when >7 A load current is required and board space allows larger SO-16 package. |
| VNQ5E120K | Quad-channel low-side driver; 120 mΩ Ron; no integrated open-coil detection or demagnetization diagnostics. | Designed for multi-solenoid systems with centralized control; requires external sensing for coil integrity verification. | Select when driving multiple solenoids from one IC and diagnostics are handled externally. |
Compared with IPS1025H and VNQ5E120K, the VN380SPTR-E uniquely combines dual-rail power architecture, open-coil detection, and demagnetization-mode diagnostics in a compact PowerSO-10 package - making it optimal for space-constrained, single-solenoid applications demanding autonomous fault response.

FAQ
What is the function of the dual Vpwr1 and Vpwr2 supplies?
Vpwr1 powers the logic and S1 excitation switch, while Vpwr2 supplies the S2 recirculation path. This separation allows independent optimization of excitation voltage and flyback energy dissipation - improving efficiency and enabling safe demagnetization even if Vpwr1 is interrupted during coil decay.
How does the open-load detection work without external components?
The VN380SPTR-E measures load current through internal sense elements and compares it to a programmable threshold (5–700 mA). When current falls below this level during an active phase, the diagnostic output latches low on the next falling edge of Input B - requiring no external shunt resistor or amplifier.
Can the VN380SPTR-E drive AC solenoids?
No. The VN380SPTR-E is designed exclusively for DC inductive loads. Its internal architecture, clamping voltages, and protection thresholds assume unidirectional current flow and DC supply rails; AC operation would violate absolute maximum ratings and disable protection functions.
What is the significance of the "TR-E" suffix in the part number?
The "TR-E" suffix indicates tape-and-reel packaging with lead-free (RoHS-compliant) finish. It specifies the ordering format for automated SMT assembly and confirms compliance with environmental directives - distinct from tube-packaged (VN380SP) or lead-free tube (VN380SP-E) variants.
