Typical Applications
ITS724GFUMA1 is suitable for 6 applications: Industrial PLC Output Module, Automotive Body Electronics, Process Control Valve Driver, LED Lighting Driver Module, 24V Industrial Relay Replacement, Building Automation I/O Module.
Industrial PLC Output Module
The ITS724GFUMA1 is well suited for 24 V industrial PLC digital output modules where four 3.3 A high-side channels can directly drive solenoid valves, relays, indicator lamps and small motor loads. Its -10 V to 16 V supply tolerance handles the negative transients specified in IEC 61131-2 for industrial control equipment, while the open-drain diagnostic flag enables the PLC CPU to detect open-circuit and short-circuit faults per channel without additional sense resistors. The PG-DSO-20-32 package keeps the PCB footprint compact for 8-, 16- and 32-channel modular I/O cards. Designers should pair each output with a TVS clamp for inductive loads and ensure the Vbb pin is decoupled with a 100 nF ceramic plus 47 Β΅F electrolytic bulk capacitor within 5 mm of the IC.
Recommended
Automotive Body Electronics
In automotive body control modules the ITS724GFUMA1 can drive door-lock actuators, seat-adjustment motors, mirror heaters and LED interior lighting from a single 12 V bus. Each channel handles inrush currents typical of incandescent bulbs (up to 10Γ nominal for 10 ms) thanks to the integrated charge pump and Smart SIPMOS output stage. Reverse-battery protection down to -10 V prevents damage from jump-start miswiring. For production automotive platforms, however, designers should select the AEC-Q100 qualified PROFET variant; the ITS724GFUMA1 industrial grade is intended for non-safety automotive convenience loads and industrial trucks where Q100 is not mandatory.
Recommended
Process Control Valve Driver
The ITS724GFUMA1 fits process-control valve-driver cards that switch 24 V solenoid-actuated pneumatic and hydraulic valves in chemical, oil-and-gas and water-treatment plants. Each of the four channels drives one valve coil, and the diagnostic feedback pin wires back to a central PLC or DCS controller to report open-load failures, a critical safety feature in SIL-2 instrumentation loops. The wide -40 C to +85 C operating range supports outdoor and unconditioned cabinet installations. The 65 mΞ© RDS(on) minimizes self-heating, allowing higher-density valve banks without active cooling.
Recommended
LED Lighting Driver Module
The ITS724GFUMA1 can drive four strings of high-brightness LEDs in architectural, signage or industrial lighting fixtures. Each channel supports PWM dimming by toggling its CMOS input at audio rates, allowing 0-100% brightness control without color-shift artifacts. The 3.3 A per-channel rating covers most 24 V LED strips and downlight arrays. The integrated short-to-ground and open-load detection protects the LEDs from wiring faults during installation. A small RC snubber on each output reduces EMI from the PWM edge transitions, important for residential lighting that must meet EN 55015 conducted-emission limits.
Recommended
24V Industrial Relay Replacement
The ITS724GFUMA1 directly replaces electromechanical relays and fuses in 24 V industrial control panels, eliminating moving parts, contact bounce, and audible click noise. Each channel can switch resistive, inductive or capacitive loads up to 3.3 A continuously, with PWM capability for soft-starting motor loads. Replacing eight 24 V relays with two ITS724G ICs reduces panel space by 60-70%, eliminates coil-driver transistors, and adds per-channel diagnostics that mechanical relays cannot provide. The PROFET's integrated protection also removes the need for separate blade fuses, simplifying wiring and reducing maintenance costs.
Recommended
Building Automation I/O Module
In building automation systems, the ITS724GFUMA1 drives HVAC damper actuators, blind motors, and 24 V lighting contactors from a BACnet or KNX-connected controller. Its four channels match the typical 4-fold grouping used in European DIN-rail I/O modules, simplifying schematic design. The diagnostic output wires directly to a building-management controller to flag actuator failures centrally, supporting predictive maintenance. The wide supply tolerance handles long cable runs where induced transients are common, and the CMOS inputs interface directly with 3.3 V or 5 V MCUs without level shifters.

Key Differentiators
- Higher continuous current per channel than same-package predecessor (vs ITS716GFUMA1)
- Proven reverse-battery tolerance down to -10 V (vs BTS724L1)
- Infineon PROFET ecosystem with extensive application notes (vs VND7140AJ (STMicroelectronics))
Design Notes
Estimated: At 3.3 A continuous per channel and 65 mΞ© RDS(on), conduction loss per channel is P = IΒ²R = 3.3Β² Γ 0.065 β 0.71 W. With all four channels at full load, total dissipation is approximately 2.8 W. The PG-DSO-20-32 package on a 4-layer JEDEC JESD51 board has a typical ΞΈJA of 70-85 C/W, so junction rise above ambient is roughly ΞT = 2.8 W Γ 80 C/W β 224 C, which exceeds the 150 C shutdown threshold. Practical designs must derate to 1.5-2.0 A per channel at 85 C ambient, or apply heatsinking copper pours on both top and bottom layers connected by thermal vias under the exposed pad.
Place the Vbb decoupling capacitor (100 nF ceramic plus 47 Β΅F electrolytic) within 5 mm of the Vbb and GND pins. The exposed die pad must be soldered to a continuous ground copper pour on the top layer with thermal vias to inner/bottom ground planes to achieve the rated thermal performance. Keep high-current output traces wide (β₯ 2 mm per ampere) and avoid 90Β° bends to reduce inductance during PWM switching.
Do not connect inductive loads without considering the avalanche energy rating. Each output can absorb a limited amount of unclamped inductive energy; for solenoid valves and motors exceeding 5 mH, add an external freewheel diode or TVS clamp across the load. Never exceed the 16 V continuous Vbb rating without the external series resistor specified in the datasheet for load-dump protection - omitting this resistor in 24 V truck systems can cause Vbb to overshoot during jump-start events.
Separate analog ground (MCU return) from power ground (load return) and join them at a single point near the ITS724G GND pins to avoid ground bounce coupling into the diagnostic feedback line. Route the ST (status) trace away from switching outputs to prevent capacitive coupling from falsely triggering fault interrupts. When using PWM dimming, keep the INx trace short and bypass with 1 nF to ground if the cable from MCU exceeds 50 mm.
Compliance Information
Industrial grade -40 C to +85 C. Not AEC-Q100 qualified; select PROFET automotive variants for Q100 applications.
