ITS4080SEPDXUMA1 Overview
A high-side power switch is a type of power distribution switch that connects a load to the positive supply rail and is controlled by a low-voltage logic-level signal from a microcontroller. It belongs to the broader category of power management ICs (PMICs) and, more specifically, the smart switch / load driver subcategory. Unlike a discrete MOSFET driven by a gate resistor network, a smart high-side switch such as ITS4080SEPDXUMA1 includes built-in charge pump, current sensing, status feedback, and fault protection, dramatically simplifying the BOM and improving system reliability in industrial automation, building control, and automotive body modules.
Key features include 80 mΩ typical RDS(on), a 45 V load-dump tolerant supply rating suitable for 24 V industrial buses, slew-rate controlled turn-on for reduced EMC emissions, a diagnostic feedback pin that reports open-load and overtemperature conditions, and a ground-loss tolerant logic interface. The integrated charge pump drives the internal N-channel MOSFET gate above the supply rail, achieving true low-loss switching without external bootstrap components.
The device uses a vertical DMOS output stage combined with a bipolar-CMOS-DMOS (BCD) mixed-signal control block. A sense-FET inside the package mirrors load current into a current sense output pin (IS pin), enabling real-time load monitoring and short-circuit detection with a programmable threshold set by an external resistor.
Typical applications include 24 V industrial PLC digital outputs, programmable logic controller (PLC) actuator drivers, solenoid and valve control, lighting relays, HVAC damper drivers, and replacement of electromechanical relays in body electronics modules. The 45 V rating comfortably covers the worst-case load-dump transient on a 24 V industrial bus.
When designing with the ITS4080SEPDXUMA1, ensure the IS sense resistor is sized for the application-specific trip current, and use a TVS or reverse-battery protection diode on VBB to survive automotive-grade transients if used in vehicle applications. Note that this is the standard PROFET grade, not the AEC-Q100 qualified automotive grade.

Typical Applications
ITS4080SEPDXUMA1 is suitable for 6 applications: 24 V Industrial PLC Digital Outputs, Solenoid and Valve Drivers, Building Automation Relay Replacement, Industrial Lighting Relay Driver, Automotive Body Electronics (Industrial Grade), Programmable Logic Controller (PLC) Actuator Drivers.
24 V Industrial PLC Digital Outputs
The ITS4080SEPDXUMA1 is purpose-built for 24 V industrial PLC digital output modules where each channel drives resistive, inductive, or lamp loads up to 8 A. Its 45 V load-dump tolerance exceeds the worst-case transient on a 24 V industrial bus per IEC 61131-2, while the 80 mΩ RDS(on) keeps conduction loss to about 5.1 W at 8 A continuous, manageable with 1 square inch of PCB copper. The integrated overcurrent and overtemperature protection allow the PLC to survive wiring faults and short circuits without external fuses, dramatically reducing field-service calls.
Recommended
Solenoid and Valve Drivers
Solenoids, hydraulic valves, and pneumatic actuators in industrial automation present high inrush currents and back-EMF transients when switched. The ITS4080SEPDXUMA1 handles the 8 A steady-state load and its controlled slew-rate turn-on reduces the inrush di/dt, extending solenoid contact life. Built-in overvoltage clamping absorbs the inductive kickback, eliminating the need for external flyback diodes and saving board space. The IS diagnostic pin lets the PLC monitor coil current in real time, enabling predictive maintenance to detect failing solenoid coils before they cause line stoppages.
Recommended
Building Automation Relay Replacement
In HVAC damper actuators, blind motors, and lighting contactors, the ITS4080SEPDXUMA1 replaces electromechanical relays with silent, arc-free solid-state switching that lasts 10x longer. The 80 mΩ RDS(on) provides low self-heating at typical 2-4 A building-automation loads, while the 5 V CMOS logic input connects directly to microcontroller GPIO without level shifters. The diagnostic IS output enables current-based load monitoring to detect stuck damper motors or burned-out lamps, integrating with BACnet or Modbus building-management systems for predictive maintenance.
Recommended
Industrial Lighting Relay Driver
For 24 V industrial lighting cabinets, indicator stacks, and tower lights, the ITS4080SEPDXUMA1 drives LED banks and incandescent lamps up to 8 A with controlled rise time to limit inrush. Its 45 V load-dump tolerance handles the inductive kickback from relay coils in adjacent equipment, and the integrated protection prevents field failures from wiring mistakes. Compared to a discrete MOSFET plus fuse, the PROFET combines current limiting, thermal shutdown, and diagnostics into a single 14-pin part, reducing the bill of materials and assembly cost.
Recommended
Automotive Body Electronics (Industrial Grade)
Although not AEC-Q100 qualified, the ITS4080SEPDXUMA1 can be used in non-safety automotive body applications such as interior lighting, accessory power outlets, and seat heaters where automotive temperature grade is not mandated. Its 80 mΩ RDS(on) handles typical 5-8 A loads, while the 45 V transient rating covers load-dump on a 12 V automotive bus. Designers should add a reverse-battery diode and TVS on VBB and validate thermal performance at 85 °C ambient, or select a true AEC-Q100 PROFET such as the BTS-series for safety-critical or under-hood applications.
Recommended
Programmable Logic Controller (PLC) Actuator Drivers
PLC actuator modules need robust high-side switches to drive 24 V relays, contactors, and motor starters from logic-level field-bus commands. The ITS4080SEPDXUMA1 accepts 5 V CMOS logic directly and provides 8 A continuous drive with on-chip diagnostics that can be fed back to the PLC CPU for fault annunciation. Its 80 mΩ RDS(on) minimizes self-heating in dense DIN-rail modules, and the PG-TSDSO-14 package fits the compact 8-channel output card form factor while dissipating heat through the PCB copper pour without an external heatsink.

Key Differentiators
- Single-channel 8 A PROFET in PG-TSDSO-14 (vs BTS51202EKAXUMA1)
- Industrial-grade 45 V load-dump rating (vs ITS4075SEPDXUMA1 (lower RDS(on) variant))
- Lower RDS(on) than ITS4100SEPDXUMA1 (vs ITS4100SEPDXUMA1)
Design Notes
At 8 A continuous load with 80 mΩ RDS(on), conduction loss is approximately 5.1 W (Estimated: P = I² × R = 8² × 0.08). The PG-TSDSO-14 package requires the exposed pad soldered to a minimum of 1 square inch of 2 oz copper on a 4-layer FR-4 PCB to keep junction temperature within 125 °C at 85 °C ambient. Without adequate copper, the device will enter thermal shutdown at significantly less than 8 A load, so verify with the datasheet SOA curve for your specific PCB layout.
Place a 100 nF ceramic decoupling capacitor as close as possible to the VBB pin (pin 3) and a 10 µF bulk aluminum-polymer or tantalum capacitor within 1 cm to handle the inrush current and supply transient ringing. The OUT pins (1, 2, 12, 13) should be connected with wide copper pours directly to the load connector; do not route through narrow traces or vias, as the 8 A load current will cause significant voltage drop and heating.
Do not connect the exposed pad (pin 14 / drain tab) to ground; it is internally tied to OUT and must be soldered to the load-side copper pour. A common mistake is to assume the EP is ground and route OUT traces separately, causing the device to overheat and trigger thermal shutdown. Also verify that the IS pin sense resistor value matches the desired overcurrent trip threshold per the datasheet's IS-vs-Iload graph.
