ITS4880R - 8-Ch 0.625A Smart High-Side Switch | Infineon
MPN: ITS4880R ✓ Hoạt độngITS4880R Tóm tắt
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.

Ứng dụng tiêu biểu
ITS4880R phù hợp cho 6 Áp dụngs: 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.

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.

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.
Được đề xuất
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.

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.
Được đề xuất
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.

- CMOS or Vbb/2 input compatibility without external level shifters (vsDiscrete N-FET high-side driver requiring gate-drive supply)

Ghi chú thiết kế
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.
