ITS716GFUMA1 概要
A smart high-side switch is a semiconductor relay that sits between the supply rail and the load, replacing electromechanical relays and fuses. Unlike a simple MOSFET, it integrates logic-level GPIO control, current sensing, slew-rate limiting, and fault reporting into a single IC. The ITS716GFUMA1 belongs to Infineon's PROFET Industrial family, which targets PLC I/O, process automation, and building-control systems where the device must survive harsh electrical environments and inductive load transients.
Key features include four independent channels each rated up to 2.3 A, SPI-compatible diagnostic feedback (open-load, short-to-ground, short-to-battery, overtemperature), very low standby current, and broad operating voltage from 5 V to 36 V (load-dump tolerant to 45 V). The vertical power FET topology minimizes on-resistance per channel while maintaining a small footprint. The PG-DSO-20-32 exposed-pad package provides a low thermal resistance of about 36 C/W, enabling sustained operation across multiple parallel channels in industrial cabinets.
The device is engineered for direct connection to a microcontroller's GPIO pins through its parallel input interface, with one logic input per channel plus a shared enable and diagnostic output. The internal charge pump and gate driver handle PWM operation up to 1 kHz for LED dimming or solenoid proportional control without external driver components. The ITS716GFUMA1 is qualified to Infineon's industrial grade (-40 C to +85 C ambient) with extended ESD and transient immunity per IEC 61000-4.
Typical applications include industrial PLC digital outputs, 24 V solenoid and valve drivers, LED indication and lighting strips, relay replacement in HVAC and building automation, and ground-switched load management in process control panels. Each channel independently drives resistive, inductive, or capacitive loads including incandescent lamps with inrush currents well above the steady-state rating.
When designing with the ITS716GFUMA1, ensure a 100 nF ceramic bypass capacitor on Vbb close to the IC and adequate PCB copper under the exposed pad for thermal dissipation. The diagnostic feedback pin requires a pull-up resistor to the microcontroller supply; software must debounce fault events because inrush loads (e.g., incandescent lamps) momentarily exceed the current-limit threshold and trip fault flags.

主な用途
ITS716GFUMA1 の用途: 6 件s: Industrial PLC Digital Outputs, 24 V Solenoid and Valve Drivers, Building Automation and HVAC, LED Indication and Lighting Strips, Relay Replacement in Industrial Control Panels, Process Control Load Switching.
Industrial PLC Digital Outputs
The ITS716GFUMA1 directly drives 24 V PLC output modules, replacing four discrete high-side MOSFETs plus protection circuitry. Its 2.3 A per-channel rating covers solenoid valves, indicator lamps, and small motor contactors typical in factory automation. Integrated short-circuit and over-temperature protection eliminates external fuses, while diagnostic feedback flags per channel feed back to the PLC logic controller for fault annunciation. Operating voltage from 5 V to 36 V tolerates industrial 24 V bus sag and surge events. The PG-DSO-20-32 footprint condenses four channels into a single IC, reducing PCB area versus discrete designs. Engineers should debounce the diagnostic output in software to avoid nuisance trips during inrush events such as solenoid engagement or incandescent lamp warm-up, and place a 100 nF Vbb bypass capacitor within 5 mm of the IC.

24 V Solenoid and Valve Drivers
The ITS716GFUMA1's 2.3 A continuous rating and high inrush tolerance suit hydraulic and pneumatic solenoid valves used in process control. Its vertical MOSFET topology handles the inductive kickback from de-energizing coils via integrated avalanche clamping, simplifying PCB layout that would otherwise require freewheeling diodes. The PWM capability up to 1 kHz enables proportional valve control for flow regulation. Wide operating voltage (5 V to 36 V) accommodates 24 V industrial supply with load-dump transients up to 45 V. The four independent channels support multi-valve manifolds with a single IC. Designers should add a small RC snubber (100 ohm + 100 nF) across each solenoid if PWM frequency exceeds 500 Hz to limit EMI; the diagnostic output allows closed-loop current monitoring via the sense feedback.
おすすめ
Building Automation and HVAC
In HVAC and building automation systems, the ITS716GFUMA1 replaces electromechanical relays for fan speed stages, damper actuators, and 24 V lighting zones. Its logic-level GPIO interface connects directly to a building controller MCU without driver transistors, and the four channels per IC reduce component count versus discrete relay boards. The exposed-pad package enables operation across the full -40 C to +85 C industrial temperature range in unconditioned electrical rooms. Diagnostic feedback supports predictive maintenance by reporting open-load faults (e.g., burned-out lamp or broken wire). A single 24 V AC-to-DC supply feeds the IC directly, and standby current is microamps when channels are off, saving energy in always-on controllers.
おすすめ
LED Indication and Lighting Strips
The ITS716GFUMA1 is well-suited to 24 V LED signage, channel letters, and architectural lighting strips, providing four independently PWM-dimmable channels per IC. PWM capability up to 1 kHz exceeds the flicker fusion threshold for human vision, while the slew-rate-controlled output reduces EMI that could interfere with adjacent audio or video circuits. Each channel's 2.3 A rating drives long LED strings with proper current-limiting resistors; diagnostic feedback reports open-load failures for remote maintenance. The 5 V to 36 V input range supports both 12 V architectural and 24 V industrial LED installations. For high-density channels, multiple ITS716GFUMA1 devices can be paralleled on the SPI-like diagnostic bus.
おすすめ
Relay Replacement in Industrial Control Panels
The ITS716GFUMA1 directly replaces electromechanical relays and their associated fuse holders in industrial control panels, cutting board space and eliminating moving parts that wear out. Four channels per IC condense what would be four relays plus four fuses into one semiconductor block with built-in protection. Wide operating voltage and load-dump tolerance meet industrial surge requirements without external TVS diodes. Logic inputs accept 3.3 V or 5 V microcontroller signals directly, simplifying interface circuitry. Diagnostic outputs feed back to the panel PLC for fault logging. For panel retrofits, the ITS716GFUMA1 can often drop into the same PCB footprint as a relay socket array, provided the original design anticipated solid-state switching.
おすすめ
Process Control Load Switching
In process control panels for chemical, water-treatment, and food-and-beverage plants, the ITS716GFUMA1 controls 24 V heaters, pumps, mixers, and sensor excitation circuits. Each channel's 2.3 A handles small fractional-horsepower motors and resistive heating elements. Parallel logic inputs connect to standard PLC output cards without intermediate drivers, and the diagnostic feedback supports SCADA fault reporting for predictive maintenance. Operating temperature from -40 C to +85 C covers unheated outdoor cabinets and indoor plant environments alike. The exposed thermal pad dissipates heat efficiently across all four channels, enabling sustained operation at full load in enclosed panels. Engineers should route the diagnostic outputs through opto-isolators if the panel MCU operates at a different ground reference.

設計ノート
All four channels operating at 2.3 A continuous from a 24 V supply can dissipate significant power in the PG-DSO-20-32 package. Solder the exposed thermal pad to a copper pour of at least 1 square inch on the top or bottom PCB layer; without adequate copper, the junction temperature may exceed 150 C under sustained full load, triggering thermal shutdown. If the application requires all four channels at peak current simultaneously, consider de-rating each channel to 1.8 A or spreading channels across two ITS716GFUMA1 devices for thermal margin.
Place a 100 nF ceramic bypass capacitor on Vbb within 5 mm of pin 14, plus a 10 uF bulk capacitor near the IC. The exposed thermal pad must be soldered with multiple thermal vias to an inner copper plane; these vias should be tented with solder mask on the top side to prevent wicking during assembly. Keep logic input traces short and away from the OUT pins to minimize crosstalk during PWM operation, and route the diagnostic STx outputs together to a shared microcontroller input bank with individual pull-up resistors.
Do not drive highly inductive loads (large solenoids, motors) above the rated 2.3 A without an external freewheeling path; while the ITS716GFUMA1 has internal avalanche clamping, sustained flyback energy can exceed the package's thermal budget. Software must debounce the diagnostic flag for at least 50 ms because inrush loads such as incandescent lamps or DC motors momentarily exceed the current-limit threshold. Finally, ensure the common EN pin is tied high or driven by the MCU before any INx pin transitions, otherwise the channels will not respond to input changes.
