ITS4880R Overview
A high-side switch is a power-distribution topology that places the MOSFET between the supply rail and the load, allowing logic-level signals to switch the grounded load safely. Within the broader semiconductor hierarchy, the ITS4880R sits in the PMIC > Power Distribution Switch / Load Driver category, often called a smart power switch or PROFET (Protected FET) when diagnostic and protection features are integrated. The 8-channel parallel architecture lets one IC replace eight discrete low-side drivers plus protection circuitry, reducing PCB area and BOM count in 24 V multi-load systems.
Key features include 0.625 A nominal per-channel current, 8 independently controlled inputs, integrated charge pump for full N-channel enhancement, common diagnostic output, embedded protection (overload, short-circuit, over-temperature, ESD, and over-voltage clamp), and CMOS or Vbb/2 input compatibility. The common-diagnostic feedback pin reports open-load and overtemperature conditions to the host MCU, simplifying firmware state machines.
Internally the ITS4880R combines a vertical DMOS output stage with a charge-pump gate driver and per-channel protection logic on a single Smart SIPMOS die. The Vbb/2 input option allows direct connection to 5 V microcontrollers without level shifters. Common diagnostic feedback consolidates eight per-channel fault signals into one pin, saving MCU GPIOs and reducing wiring complexity in 24 V PLC and industrial-automation backplanes.
Typical applications include 24 V industrial automation (PLC digital outputs), process-control solenoid and valve drivers, building-automation relay replacement, sensor and indicator power distribution, machine-tool lamp and actuator control, and HVAC damper/valve arrays. The wide Vbb tolerance and load-dump rating make it well suited to factory-floor environments with long cable runs and inductive transients.
When designing with this device, derate per-channel current to roughly 0.4-0.5 A continuous when all eight channels conduct simultaneously, because the PG-DSO-36-26 package shares thermal capacity. Always place a reverse-polarity and TVS clamp on Vbb, and use series inductance mitigation (freewheel diode or TVS) when switching solenoids or relays.

ITS4880R Safe Operating Area (per channel)
Typical Applications
ITS4880R is suitable for 6 applications: PLC Digital Output Modules, Industrial Solenoid and Valve Drivers, Building Automation Relay Replacement, Sensor and Indicator Power Distribution, Machine-Tool Lamp and Actuator Control, HVAC Damper and Valve Arrays.
PLC Digital Output Modules
The ITS4880R's 8 independent 0.625 A high-side channels and CMOS/Vbb/2 inputs make it a direct fit for 24 V PLC digital-output modules conforming to IEC 61131-2. Each channel replaces a discrete low-side FET plus flyback diode with one integrated smart switch, slashing PCB area in 16-, 32-, and 64-point output cards. The common-diagnostic feedback pin reports open-load and over-temperature to the backplane MCU, satisfying IEC 61131-2 diagnostic requirements without per-channel wiring. Compared to 8 discrete PROFETs, the ITS4880R consolidates the BOM, simplifies the firmware state machine, and tightens channel-to-channel matching for symmetric turn-on across all output points.
Recommended
Industrial Solenoid and Valve Drivers
Solenoids and proportional valves in 24 V process control typically draw 0.2-0.6 A steady-state, aligning directly with the ITS4880R's 0.625 A per-channel rating. The integrated over-voltage clamp absorbs inductive flyback when the solenoid is de-energized, eliminating external freewheel diodes in most 24 V hydraulic and pneumatic manifolds. The 60 V load-dump rating covers the harshest IEC 61131-2 transient profiles seen on long factory-floor cable runs. Eight channels per IC let one ITS4880R drive an entire 8-valve manifold, sharing one thermal pad and one common-diagnostic pin with the host PLC.
Recommended
Building Automation Relay Replacement
Building-automation backplanes traditionally use 24 V electromechanical relays to switch lighting, fans, and blinds; the ITS4880R replaces each relay with a silent, solid-state high-side switch rated 0.625 A. Eight channels fit a standard DIN-rail module footprint, and the CMOS input interfaces directly with the building controller's 3.3 V or 5 V GPIO without level shifters. Diagnostic feedback lets the BMS detect lamp failure or stuck actuator without extra current-sense circuitry. The ITS4880R's long-term reliability (no moving contacts) suits 24/7 HVAC and lighting control loops where relay wear drives maintenance cost.
Recommended
Sensor and Indicator Power Distribution
Industrial 24 V backplanes often need to power banks of proximity sensors, panel indicators, and status LEDs with per-channel switching and fault reporting. The ITS4880R's 8 channels and 0.625 A rating comfortably drive 8 indicator lamps or sensor clusters from a single IC. Open-load detection flags burnt-out lamps or disconnected sensors without a separate diagnostic MCU pin per channel. The wide 11 V to 45 V Vbb tolerance covers 24 V nominal plus battery-backup transitions in remote telemetry panels, where supply sag during grid events is common.
Recommended
Machine-Tool Lamp and Actuator Control
Machine-tool enclosures use 24 V halogen work-lamp arrays and small actuators that together draw well under 5 A total - a perfect match for the ITS4880R's 8 x 0.625 A architecture. The common-diagnostic feedback tells the CNC controller when a lamp burns out, supporting predictive maintenance dashboards. The PG-DSO-36-26 exposed-pad package mounts directly to the machine's aluminum chassis via an insulated thermal pad, sharing heat with the rest of the cabinet. Compared to relay-based lamp control, the ITS4880R eliminates the audible click that contaminates metrology environments and removes contact bounce from PWM-dimmed lamps.
Recommended
HVAC Damper and Valve Arrays
HVAC air-handling units typically have 6-8 modulating dampers and on/off water valves that must be switched from a central 24 V controller. The ITS4880R's 8 channels directly drive this load count without additional driver stages, and the CMOS input logic interfaces with standard BACnet or Modbus controller GPIOs. The 60 V load-dump rating handles the long inductive cable runs common in retrofit installations, where valve solenoids generate significant flyback. The common-diagnostic pin simplifies the building management system's fault detection, reporting damper-stuck or coil-open conditions back to the central controller in real time.

Key Differentiators
- 8 channels consolidated in one PG-DSO-36-26 package with shared thermal pad and common diagnostic (vs 8 discrete PROFET low-side switches)
- CMOS or Vbb/2 input compatibility without external level shifters (vs Discrete N-FET high-side driver requiring gate-drive supply)
- 60 V load-dump rating and integrated over-voltage clamp on every channel (vs ITS4100S-SJ-N with similar package but lower per-channel headroom)
Design Notes
Estimated: With all 8 channels conducting 0.625 A into 24 V loads, total power dissipation in the ITS4880R can reach 8 x (24 V - Vload) x Iout. For a typical 24 V load at 0.5 A, the per-channel dissipation is roughly 0.5 W and total IC dissipation is 4 W. The PG-DSO-36-26 thermal pad should be soldered to a continuous GND copper pour of at least 6 cm squared on a 4-layer board, with thermal vias to the inner GND plane, to keep the junction temperature below 125 C. Derate per-channel current to roughly 0.4-0.5 A when all eight channels conduct simultaneously.
Place the Vbb decoupling capacitor (>= 100 nF ceramic plus 10 uF bulk) as close as possible to the Vbb pins (10, 11, 26) of the PG-DSO-36-26. Each OUTx pin should connect to its load with a wide trace (>= 0.5 mm) or copper pour to handle 0.625 A without significant voltage drop. The exposed thermal pad must be soldered to GND with an array of thermal vias to spread heat into inner copper layers. Keep input traces (IN1-IN8) short and routed away from the OUTx switching nodes to avoid capacitive coupling that could re-trigger the input logic.
Do not exceed the 60 V load-dump rating on Vbb - in 24 V industrial vehicles or plants with long inductive cable runs, transients can reach 60 V or more and require an external TVS clamp. The common-diagnostic feedback pin is an open-drain output in some PROFET variants; verify the pull-up voltage in the datasheet before connecting to a 3.3 V MCU. The Vbb/2 input option requires the Vbb rail to be present and stable; if Vbb is missing, Vbb/2 logic levels are undefined and may spuriously turn channels on. Always validate the open-load detection threshold against the actual load resistance at turn-off to avoid false open-load alarms on long cable runs.
