Product details

Overview

VNQ860SPTR-E from STMicroelectronics is a quad-channel high-side driver IC realized in VIPower M0-3 technology, designed to switch resistive, capacitive, and inductive loads with one side grounded. It delivers per-channel R_DS(on) ≤ 270 mΩ at T_J = 25 °C, supports V_CC up to 41 V, and integrates active current limiting (I_LIM = 0.35–1.1 A), thermal shutdown (T_TSD = 150–200 °C), and ground-disconnection detection-making it suitable for IEC 61131-compliant industrial control modules.

For engineers reviewing the VNQ860SPTR-E datasheet, VNQ860SPTR-E pinout, VNQ860SPTR-E application, or VNQ860SPTR-E equivalent, key selection criteria include channel-wise diagnostic status reporting, fast demagnetization clamping (V_DEMAG = V_CC − 52 V), undervoltage/overvoltage protection thresholds (4 V / 42 V), and PowerSO-10™ thermal performance (R_th(j-c) = 1.4 °C/W).

Technical Context

The device implements four independent high-side power switches with CMOS-compatible logic inputs and dedicated status outputs per channel. Each channel features integrated current sensing, thermal foldback, and automatic restart after fault clearance-enabling robust operation under repetitive short-circuit or overload conditions without external supervision.

Its protection architecture includes per-channel overcurrent detection via internal sense-FET monitoring, junction temperature-based thermal shutdown with 15 °C hysteresis, and loss-of-ground detection that forces output disable when GND pin voltage drops below −200 mA reverse current threshold-ensuring fail-safe behavior in harsh industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	5.5 V to 36 V operating supply; absolute max 41 V-supports wide industrial rail voltages including 24 V DC systems.
R_DS(on)	≤ 270 mΩ @ I_OUT = 0.25 A, T_J = 25 °C-minimizes conduction loss and self-heating during sustained load drive.
I_OUT Limit	0.35 A typical current limit per channel-enables safe driving of solenoids, relays, and small motors without external fusing.
t_ON/t_OFF	10 μs turn-on / 40 μs turn-off delay-provides predictable timing for PLC output staging and synchronized actuator control.
V_DEMAG	V_CC − 52 V clamp voltage-suppresses inductive kickback during relay/solenoid de-energization without external snubbers.
U/V Shutdown	Undervoltage lockout at 4 V; overvoltage shutdown at 42 V-prevents erratic switching during brownout or surge events.
Standby Current	70–120 μA @ V_CC = 24 V-enables low-power hold states in battery-backed or energy-sensitive systems.

Pinout & Package

Package: PowerSO-10™ (10-pin exposed-pad surface-mount package with thermal pad on underside; ECOPACK® compliant).

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Power supply input	Primary high-side rail connection; supports up to 41 V DC; ties to internal charge pump and protection comparators.
GND	Ground reference	System return path; loss-of-ground detection triggers immediate channel disable and status flag assertion.
IN1–IN4	Logic input (x4)	CMOS-compatible digital inputs (V_IL ≤ 1.25 V, V_IH ≥ 3.25 V); each controls one high-side switch independently.
OUT1–OUT4	High-side output (x4)	Drives load between OUTx and system ground; includes integrated freewheeling diode (V_F = 1 V @ −0.3 A).
STAT1–STAT4	Status output (x4)	Open-drain fault indicators-pulled low during overcurrent, overtemperature, UV/OV, or ground loss on corresponding channel.

Key Features

Feature	Design Value
Per-channel diagnostics	Dedicated open-drain STATx pins report real-time fault status (thermal, current, UV/OV, ground loss) without multiplexing or polling overhead.
Fast inductive demagnetization	V_DEMAG = V_CC − 52 V clamp ensures rapid energy dissipation from coils-reducing arcing and contact wear in relay drivers.
Loss-of-ground protection	Automatic channel disable when GND pin sinks >200 mA reverse current-prevents uncontrolled load activation during wiring faults.
Thermal hysteresis	15 °C reset margin (T_R = 135 °C after T_TSD = 150 °C) prevents oscillation near thermal limit during sustained overload.
Reverse polarity resilience	With external RGND resistor, survives −V_CC applied to GND pin-enabling robust field wiring in mobile or maintenance-prone equipment.

Applications

PLC Digital Output Module

Numerical Control Machine I/O

Use Scenario: Driving 24 V DC solenoids and indicator lamps in modular programmable logic controller racks.

Use Scenario: Controlling coolant pumps, tool changers, and axis brakes in CNC machine tool cabinets.

IC Role / Device Role / Timing Role: Load driver with fast demagnetization (V_DEMAG = V_CC − 52 V) and thermal foldback for intermittent high-current actuation.

Use Value: Eliminates need for external flyback diodes and thermal sensors-simplifying PCB layout and improving reliability in vibration-prone enclosures.

Industrial PC Peripheral Interface

IEC 61131-2 Compliant Output Stage

Use Scenario: Isolating and driving field devices (valves, alarms, sensors) from embedded industrial PCs with limited GPIO drive capability.

IC Role / Device Role / Timing Role: Level-shifting interface translating 3.3/5 V logic signals into 24 V high-side switched outputs with fault feedback.

Use Value: Enables direct microcontroller interfacing without optocouplers or level shifters-reducing latency and component count in compact edge controllers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPS2050H	Single-channel, higher R_DS(on) (400 mΩ), no integrated demag clamp, requires external status conditioning.	Suitable for lower-density designs where per-channel diagnostics are not required and board space allows discrete protection.	Select when consolidating multiple single-channel drivers offers better thermal distribution than quad integration.
TPS27082L	Quad-channel but lacks loss-of-ground detection, lower V_CC max (36 V), no V_DEMAG clamp-relies on external TVS.	Better suited for consumer-grade 24 V systems without IEC 61131 compliance needs or aggressive inductive load cycling.	Choose only if ground integrity is assured and demagnetization energy is managed externally.

Compared with VNQ860SPTR-E, IPS2050H trades integration for thermal flexibility and TPS27082L reduces protection depth to achieve smaller footprint-neither matches the combined per-channel diagnostic fidelity, V_DEMAG clamping, and ground-loss immunity essential for certified industrial I/O.

FAQ

What is the maximum continuous output current per channel?

The VNQ860SPTR-E provides a typical current limit of 0.35 A per channel under normal operating conditions, with a maximum specified limit of 1.1 A during transient overload. Sustained current must remain within thermal limits defined by PCB copper area and ambient temperature-derating is required above 135 °C case temperature.

Does VNQ860SPTR-E require external flyback diodes for inductive loads?

No. The device integrates an internal V_CC-to-OUT clamp diode with forward voltage of 1 V at −0.3 A, and features active demagnetization clamping at V_DEMAG = V_CC − 52 V. This eliminates the need for external flyback diodes in most 24 V industrial solenoid and relay applications.

How does the loss-of-ground protection function work?

When reverse current exceeding −200 mA flows into the GND pin, internal circuitry detects ground disconnection and forces all outputs OFF while asserting low-level status on corresponding STATx pins. This occurs within microseconds and is independent of input logic state-ensuring fail-safe behavior during wiring faults.

Can VNQ860SPTR-E be used with 3.3 V microcontroller GPIOs?

Yes. Its logic inputs are CMOS-compatible with V_IL ≤ 1.25 V and V_IH ≥ 3.25 V, making them directly drivable by standard 3.3 V microcontrollers. Input hysteresis of 0.5 V ensures noise immunity, and input leakage remains below 10 μA at V_IN = 3.25 V-minimizing loading on MCU pins.
