ITS4035SEPDXUMA1 Обзор
A smart high-side switch is a type of power distribution switch that sits between the system supply and the load, providing both load-driving capability and integrated protection features (overcurrent, overtemperature, short-circuit, ground-loss, and reverse-polarity protection). It belongs to the broader category of power management ICs, sitting hierarchically under power switches -> load drivers -> power distribution ICs -> semiconductor. Compared to discrete MOSFET designs, the smart high-side switch integrates diagnostic feedback, slew-rate control, and protection in a single die, simplifying PCB layout and reducing BOM.
Key features include a typical R<sub>DS(ON)</sub> of 35 mΩ at 25 °C, an active-high logic-level enable input, open-drain status flag output, integrated thermal shutdown with auto-restart, and Infineon's PROFET™ protection suite including overvoltage clamp and current limitation. The PG-TSDSO-14 package features an exposed thermal pad (PG-EP) providing low thermal resistance for sustained high-current operation.
The architecture uses an N-channel MOSFET configured as a high-side switch with charge-pump gate drive, supporting a wide logic-level input interface for direct connection to microcontrollers. Its 35 mΩ on-resistance minimises conduction losses at full load, while the built-in current-limit and temperature monitoring ensure robust operation in fault conditions.
Typical applications include industrial PLCs, factory automation loads, programmable logic controllers, solenoid and valve drivers, lighting relay replacements, and protected 24 V power distribution in building automation. The wide operating voltage range also makes it suitable for 12 V/24 V battery-driven systems in commercial vehicles and rugged industrial equipment.
When designing with this device, ensure the input capacitor (typically 100 nF close to Vbb) and sufficient PCB copper area on the exposed pad are provided for thermal dissipation. The status output requires a pull-up resistor to logic high, and the enable logic must be observed during system power-up sequencing to avoid inrush glitches.

Типичное применение
ITS4035SEPDXUMA1 подходит для 6 применениеs: Industrial PLC Digital Outputs, 24V Industrial Load Switching, Building Automation Power Distribution, Solenoid and Valve Drivers, Lighting Relay Replacement, Commercial Vehicle 24V Power Switching.
Industrial PLC Digital Outputs
The ITS4035SEPDXUMA1 is ideal for industrial PLC digital output modules driving 24 V solenoid valves, relays, and indicator lamps. Its 13.2 A continuous current and 35 mΩ R<sub>DS(ON)</sub> handle multi-axis machine loads without external heatsinking beyond PCB copper, while the programmable 3-13.2 A current limit protects wiring harness shorts typical in factory floors. The integrated overtemperature shutdown with auto-restart and ground-loss protection reduce field failure rates compared to discrete MOSFET designs, and the open-drain status output feeds back to the PLC CPU for diagnostic verification of each output's health in real time.
Рекомендуется
24V Industrial Load Switching
The ITS4035SEPDXUMA1 directly drives 24 V industrial loads such as motor brakes, clutch coils, heaters, and hydraulic actuators from a single high-side switch. Its 5 V to 28 V Vbb range covers the full industrial 24 V bus including transients up to 35 V load-dump, and its active-high CMOS-compatible enable input interfaces directly with 3.3 V or 5 V microcontroller GPIO. The exposed thermal pad efficiently dissipates the conduction loss (≈ 6 W at full 13.2 A load), and the PROFET reverse-polarity protection withstands miswiring during field installation, a common cause of industrial load-switch failures.
Рекомендуется
Building Automation Power Distribution
The ITS4035SEPDXUMA1 enables protected 24 V power distribution in building automation systems including HVAC actuators, smart lighting controls, and access-control relays. Its 35 mΩ R<sub>DS(ON)</sub> keeps conduction losses low even at sustained 5-10 A loads, reducing thermal stress in enclosed wall-mounted control cabinets. The diagnostic status flag provides per-channel fault feedback to the building management system (BMS), and the integrated short-circuit and overcurrent protection eliminates the need for replaceable fuses, dramatically reducing field maintenance costs over the system's lifetime.
Рекомендуется
Solenoid and Valve Drivers
The ITS4035SEPDXUMA1 drives 24 V DC solenoid valves and pneumatic actuators in process control and factory automation. Its slew-rate-controlled turn-on/turn-off reduces electromagnetic emissions (EME) on long cable runs, an EMC challenge in industrial valve manifolds. The programmable current limit can be set below the solenoid's inrush current to limit supply transients when multiple valves switch simultaneously, and the open-drain status output returns a per-channel health flag for predictive maintenance in Industry 4.0 architectures.
Рекомендуется
Lighting Relay Replacement
The ITS4035SEPDXUMA1 replaces mechanical relays and discrete MOSFETs in industrial and architectural lighting control, providing silent solid-state switching with no contact bounce or coil inductance. Its 13.2 A continuous rating covers LED array strings, fluorescent ballasts, and incandescent loads in commercial installations, while the integrated protection suite prevents catastrophic failure from short circuits in aged fixtures. The exposed-pad PG-TSDSO-14 package supports sustained high current with PCB copper heatsinking alone, simplifying fixture design and improving long-term reliability over electromechanical relays.
Рекомендуется
Commercial Vehicle 24V Power Switching
The ITS4035SEPDXUMA1 is well-suited for 24 V commercial vehicle body-control applications including load-switching for auxiliary lamps, horns, pumps, and HVAC blowers. Its 5-28 V operating range tolerates 24 V truck and bus electrical systems with load-dump transients, and the -40 °C to +150 °C operating temperature handles underhood and chassis mounting. The PROFET reverse-polarity and ground-loss protection withstands jump-start miswiring and chassis-ground fault conditions common in fleet vehicle service, reducing warranty returns versus unprotected discrete designs.

Заметки по проектированию
Estimated: at full 13.2 A load and 35 mΩ R<sub>DS(ON)</sub>, conduction loss is approximately 6.1 W (I²R = 13.2² × 0.035). The PG-TSDSO-14 exposed thermal pad MUST be soldered to a PCB copper area of at least 1 square inch (≈ 6 cm²) of 2 oz copper to keep junction temperature rise below 50 °C above ambient. In enclosed industrial cabinets with limited convection, additional copper area or a small heatsink may be required for sustained full-load operation.
Place a 100 nF ceramic decoupling capacitor as close as possible to the Vbb pin to suppress supply transients from the inductive load. The exposed thermal pad should use multiple thermal vias (at least 9 vias in a 3x3 grid, 0.3 mm drill) to conduct heat to the inner PCB copper planes. Wide copper traces (at least 0.5 mm per ampere) on OUT and Vbb minimise voltage drop and secondary heating of the PCB.
Do not exceed the absolute maximum Vbb rating of 28 V sustained (load-dump transients up to 35 V are tolerated briefly). Always provide a pull-up resistor on the open-drain ST status output (typically 10 kΩ to 5 V) - leaving it floating will not damage the device but will mask diagnostic faults. When driving inductive loads (solenoids, relays), add a flyback/clamping diode across the load - the ITS4035SEPDXUMA1's internal overvoltage clamp is not designed for continuous freewheeling energy dissipation.
