Typical Applications
ITS4090QEPDXUMA1 is suitable for 6 applications: Industrial PLC Digital Output Modules, 24V/48V Industrial Relay Replacement, Automotive Body Control Modules, Building Automation and HVAC Actuators, 24V Sensor and Indicator Power Distribution, Solid-State Relay Replacement in Test Equipment.
Industrial PLC Digital Output Modules
The ITS4090QEPDXUMA1 is well matched to 24V PLC digital output modules where four isolated 750 mA channels must switch solenoid valves, indicator lamps, and small DC loads from a logic-level MCU. Its 90 mΩ typical RDS(ON) limits conduction loss per channel to roughly 50 mW at 750 mA, keeping total package dissipation under 2 W with adequate copper pour. Integrated short-circuit and over-temperature protection eliminates external fuses and PTCs, while the analog IS pin delivers a current proportional to load current for wire-break and overload diagnostics required by IEC 61131-2. Compared with discrete MOSFET designs, a single quad-channel IC shrinks the output-stage PCB area by roughly 60%.
Recommended
24V/48V Industrial Relay Replacement
Engineers replacing electromechanical relays with solid-state switches use the ITS4090QEPDXUMA1 to switch 24V coil loads and small heating elements. With a 45V absolute maximum rating, the same device also drives 48V mild-hybrid bus loads such as aux pumps and HVAC valves. The PROFET family supports PWM dimming and proportional control up to about 1 kHz, allowing the same IC to drive resistive heaters, LED strings, and proportional solenoids. Reverse-battery protection via a single 150 Ω GND-path resistor eliminates the diode drop of legacy solutions, and the on-chip diagnostic pin supports predictive maintenance by reporting partial-load degradation.
Recommended
Automotive Body Control Modules
In 12V automotive body controllers, the ITS4090QEPDXUMA1 drives seat-heater pads, mirror heaters, lighting strips, and small motors where each channel stays below 750 mA continuous. Although not AEC-Q100 qualified in this specific variant, the device shares its silicon with PROFET 24V/48V automotive-grade parts in the same PG-TSDSO-14 package. The exposed-pad PG-TSDSO-14 footprint simplifies PCB thermal design versus TO-252 alternatives. Integrated reverse-polarity, jump-start (45V), and load-dump survival features meet common automotive stress-test requirements when paired with the recommended 150 Ω GND resistor.
Recommended
Building Automation and HVAC Actuators
The ITS4090QEPDXUMA1 fits 24V building-automation actuator drivers for damper motors, valve actuators, and addressable lighting nodes. The quad-channel architecture lets one IC replace four SPST relays plus their snubbers, reducing both PCB area and audible relay-click noise. PROFET protection features prevent damage from stalled actuators, while the IS diagnostic pin supports BACnet or Modbus fault reporting back to a building-management system. The 45V supply tolerance also supports centrally rectified 24VAC systems when DC-bulk filtered.
Recommended
24V Sensor and Indicator Power Distribution
In distributed I/O systems, the ITS4090QEPDXUMA1 powers 24V field sensors, indicator stacks, and beacon lights from a 4-wire cable carrying logic and load power. Each channel's 750 mA capacity covers most industrial sensor clusters, while the IS diagnostic pin detects open-circuit and short-circuit conditions at the load end. Reverse-polarity and over-voltage protection prevents field-wiring errors from destroying the head-end electronics. Compared with discrete high-side switches per channel, the quad IC simplifies EMC layout by sharing a common thermal and ground return.
Recommended
Solid-State Relay Replacement in Test Equipment
Test-and-measurement instruments use the ITS4090QEPDXUMA1 to switch low-current DC loads during automated test sequences, replacing electromechanical SSRs that wear out and create inductive kickback. The PROFET's integrated protection lets designers skip fuse holders and PTCs, while the analog IS pin enables per-channel load-current verification. The 1 kHz PWM capability supports soft-start of capacitive loads without inrush current trips. Compared with photo-MOS SSR solutions, the PROFET offers faster turn-off, integrated diagnostics, and lower on-resistance at 24V rails.

Key Differentiators
- Lowest RDS(ON) in the PROFET 24V/48V quad-channel family (vs ITS4130QEPDXUMA1)
- Highest per-channel current rating in this package (vs ITS4300SSJDXUMA1)
- 4-channel integration in PG-TSDSO-14 (vs ITS4200SSJDXUMA1)
Design Notes
Estimated: at 4 × 750 mA simultaneous load with 24V supply and RDS(ON) = 90 mΩ typical, total package dissipation reaches roughly 2.0 W. The PG-TSDSO-14 exposed pad requires a minimum copper pour of 1 square inch on a 1 oz 4-layer PCB to keep the junction below 150 °C at 85 °C ambient. Without the exposed pad soldered to adequate copper, the device will trigger thermal shutdown under full load. Always follow the Infineon PG-TSDSO-14 footprint recommendation in the datasheet thermal-layout section.
The ITS4090QEPDXUMA1 requires a 150 Ω resistor between the GND pin and board ground for reverse-polarity protection; omitting this component destroys the device if the supply leads are reversed. The IS diagnostic pin sources a current proportional to load current and must connect through an external sense resistor to ground - do not connect IS directly to an ADC input. NC pins (12, 13, 14) must be left floating or tied to GND; connecting them to VS can cause internal latch-up.
Place the VS decoupling capacitor (≥ 100 nF ceramic plus 10 µF bulk) within 5 mm of the VS pin to suppress inductive load transients. Route the four output traces with wide copper pours and avoid sharp bends; high-side switches see full load-current transients during PWM edges. Keep the GND trace from the 150 Ω reverse-polarity resistor directly back to the system ground plane star-point; do not daisy-chain ground returns through the IC GND pin.
The IS pin can source up to several mA depending on channel current; select the IS sense resistor so the maximum diagnostic voltage stays below the ADC reference of the supervising MCU. For PWM operation, observe the 1 kHz maximum typical switching frequency; faster edges may exceed the device's slew-rate-controlled turn-on and re-trigger short-circuit protection falsely. The 4 logic inputs are TTL/CMOS compatible; no pull-ups are required when driven from a 3.3 V or 5 V MCU GPIO.
