ITS6080SEPDXUMA1 Overview
A high-side switch (HSS) is a power distribution IC that sits between a positive supply rail and a load, allowing a low-voltage logic signal (typically 3.3V or 5V microcontroller GPIO) to control a much larger load current while providing protection against overloads, short circuits, and thermal faults. Compared with a discrete MOSFET plus fuse solution, an intelligent high-side switch integrates the power transistor, charge pump gate drive, current sense, and fault diagnostics into a single package, reducing PCB area, BOM count, and design complexity. The ITS6080 belongs to the family tree: high-side switch -> power distribution switch -> power management IC -> semiconductor.
Key specifications include 75 mOhm typical on-resistance at 25C, an operating supply range of 5V to 34V (with load-dump survival up to 62V), 8A continuous drain current, and integrated protections including overload current limiting, short-circuit shutdown, thermal shutdown, over-voltage clamp, and ESD protection. The device offers proportional load current sense output for diagnostic monitoring and an active-low fault feedback pin for system-level safety.
The ITS6080 employs a vertical DMOS output stage with an integrated charge pump that fully enhances the N-channel MOSFET regardless of supply voltage, achieving true low-Rds(on) across the full operating range. This contrasts with older P-channel high-side architectures that suffer from higher on-resistance at low supply voltages. The device is qualified to AEC-Q100 for automotive harsh environments.
Typical applications include driving resistive, inductive, and capacitive loads such as solenoids, valves, relay coils, LED strings, motors, and heaters in body electronics modules, industrial automation PLCs, and process control systems. The 8A rating suits medium-power actuators where a robust, self-protected switch replaces discrete solutions.
When designing with this device, derate the load current for ambient temperature and PCB copper area. Use a 100nF ceramic decoupling capacitor directly at Vbb and follow the application note's PCB layout guidelines to ensure the exposed pad dissipates heat efficiently into the copper plane.

Typical Applications
ITS6080SEPDXUMA1 is suitable for 6 applications: Automotive Body Electronics Module Load Driving, 24V Industrial Solenoid and Valve Control, LED Lighting String Driver, Relay and Contactor Coil Drive, Process Control and PLC Discrete Output Module, Heating Element and Resistive Load Driver.
Automotive Body Electronics Module Load Driving
The ITS6080SEPDXUMA1 drives 12V body electronics loads such as door lock actuators, mirror heaters, and lighting modules directly from 8-bit or 32-bit microcontroller GPIO. Its 75 mOhm Rds(on) limits conduction loss to roughly 0.6W at 8A, keeping the PG-TSDSO-14 package within thermal limits without external heatsinking on 1-2 sq inch copper pours. The proportional current-sense output enables fault detection of open-load, short-to-ground, and over-current conditions, while AEC-Q100 qualification allows deployment under-the-hood adjacent to engine control units.
Recommended
24V Industrial Solenoid and Valve Control
For 24V industrial solenoid valves, proportional valves, and hydraulic actuators, the ITS6080SEPDXUMA1's 34V continuous operating range and 62V load-dump tolerance directly support industrial bus environments. The 8A rating covers most proportional solenoid applications; the integrated active clamp absorbs inductive flyback energy without external freewheeling diodes, simplifying PCB layout. The diagnostic current-sense output allows the PLC or industrial controller to detect valve stiction and partial-winding shorts, enabling predictive maintenance. PG-TSDSO-14's exposed thermal pad efficiently couples to DIN-rail-mounted PCB copper.
Recommended
LED Lighting String Driver
In automotive tail-light, daytime running light, and architectural LED driver applications, the ITS6080SEPDXUMA1 provides a constant-current or PWM-dimmable high-side drive for LED strings drawing up to 8A. The device's low 75 mOhm Rds(on) minimizes voltage drop in the wiring harness, preserving luminous flux accuracy. The current-sense diagnostic output allows the MCU to monitor LED forward current and detect open-string or shorted-LED faults. PG-TSDSO-14 surface-mount package supports automated assembly for high-volume automotive lighting production lines.
Recommended
Relay and Contactor Coil Drive
The ITS6080SEPDXUMA1 replaces electromechanical relays with a solid-state high-side switch for driving contactor coils in motor starters and HVAC systems. With 8A peak handling, it can energize large 24V contactor coils; the integrated inductive load clamping eliminates the need for flyback diodes across the coil. The fault feedback pin signals the controller if the coil wiring develops a short, enabling rapid protection. Compared with a discrete MOSFET plus relay, this approach reduces PCB area and improves switching reliability over millions of cycles.
Recommended
Process Control and PLC Discrete Output Module
PLC discrete output modules in industrial automation use the ITS6080SEPDXUMA1 to switch 24V field devices such as motor starters, indicator lamps, and small DC loads. The device's 5V-34V input range accepts standard PLC backplane 24V rails; the 75 mOhm Rds(on) ensures minimal heat dissipation in densely populated 8-16 channel modules. PROFET diagnostic feedback supports IEC 61131-3 fault reporting, while the AEC-Q100 automotive-grade silicon provides reliability headroom in harsh factory environments with temperature swings.
Recommended
Heating Element and Resistive Load Driver
For PTC heater elements, seat heaters, mirror heaters, and small resistive loads in 12V/24V systems, the ITS6080SEPDXUMA1 provides PWM-controlled power delivery up to 8A. The low 75 mOhm Rds(on) limits dissipation to a few watts even at 8A continuous, allowing direct PCB mounting without heatsinking. The current-sense output enables closed-loop temperature control via resistance measurement, and thermal shutdown provides redundant safety. PG-TSDSO-14 with exposed pad efficiently dissipates heat into PCB copper pour for high-duty-cycle heating applications.

Design Notes
At 8A continuous load, the ITS6080SEPDXUMA1 dissipates approximately 4.8W (P = I²R = 64 × 0.075). The PG-TSDSO-14 exposed thermal pad must be soldered to a minimum 1 square inch of copper pour, preferably with thermal vias to an internal ground plane, to maintain junction temperature within the 150C rating. Without adequate copper, the device will enter thermal shutdown at loads below the 8A rating. Derate to roughly 50% of rated current if ambient temperature exceeds 85C.
Place a 100nF ceramic decoupling capacitor directly between Vbb (pin 1) and GND (pin 3) within 5mm of the package. Use wide copper traces on Vbb and OUT pins to minimize voltage drop and thermal resistance. Connect the exposed thermal pad to a large copper area with multiple thermal vias (0.3mm drill, 1mm pitch) for efficient heat spreading into inner PCB layers.
Do not exceed the 62V load-dump transient rating, even briefly. Ensure the IS (current sense) output pin has a low-impedance load and is not left floating, as floating IS can cause diagnostic errors. When driving inductive loads, the integrated active clamp handles flyback energy; do not add external freewheeling diodes across the load as this can interfere with the clamp behavior and cause device failure.
The IN (logic input) pin is 3.3V/5V CMOS compatible with internal pull-down; no external pull-down resistor is needed. The FAULT pin is open-drain and requires an external pull-up (typically 10kOhm to Vcc). For PWM dimming applications above 1 kHz, the IS pin bandwidth (typically 50 kHz) limits diagnostic accuracy - derate or filter the IS signal for high-frequency PWM.
