ITS711L1FUMA1 概述
Key features include an integrated charge pump for N-channel vertical power FET operation, ground-referenced CMOS-compatible logic inputs, embedded diagnostic feedback for each channel, and monolithic protection functions including over-load, over-voltage, over-temperature, and short-circuit handling. The PROFET (Protected FET) Industrial family design replaces electromechanical relays and discrete MOSFET driver circuits, providing a single-chip solid-state solution.
The ITS711L1 is a member of the high-side switch category within the broader power distribution switch hierarchy. High-side switches sit between the supply rail and the load (versus low-side switches which sit between load and ground), allowing them to provide complete load disconnect and ground-referenced control logic. The 1:1 input-to-output ratio and four parallel outputs make this part suitable for driving multiple resistive, inductive, or capacitive loads from a single microcontroller I/O bus.
Technical depth: the device integrates four vertical N-channel power MOSFETs, a charge pump to drive the high-side gates above the supply rail, CMOS input buffers, and per-channel sense/current-limit circuitry. Diagnostic feedback (open-drain status) lets the host microcontroller distinguish normal operation from open-load, short-to-ground, short-to-battery, and thermal shutdown events. The Smart SIPMOS process combines a vertical DMOS power stage with CMOS control logic on a single die.
Typical applications include industrial automation PLC outputs, 24V solenoid and valve drivers, building management relay replacement, programmable logic controller (PLC) discrete outputs, and machine safety interfaces. The wide 5V-34V input range covers both 12V automotive subsystems and 24V industrial battery-backed rails.
When designing with the ITS711L1FUMA1, derate output current at elevated ambient temperatures following the thermal resistance curve in the datasheet, and place sufficient copper pour under the exposed pad to keep junction temperature below the shutdown threshold. Inputs are CMOS-compatible, eliminating the need for level-shifters in 3.3V or 5V microcontroller systems.

典型应用
ITS711L1FUMA1 适用于 6 应用s: Industrial PLC Digital Outputs, 24V Solenoid and Valve Drivers, Building Management Relay Replacement, Programmable Logic Controller (PLC) Discrete Outputs, Industrial Machine Safety Interfaces, 12V Automotive Body Electronics.
Industrial PLC Digital Outputs
The ITS711L1FUMA1 fits industrial PLC digital output modules because each of its four 1.7A channels can directly drive a 24V industrial load from a CMOS-compatible logic input. With load voltage range of 5V to 34V it covers both 24V nominal and 30V worst-case industrial rails. Its embedded protection (over-temperature, over-load, short-circuit) eliminates external fuse or PTC components per channel, reducing PLC module BOM cost and PCB area. Diagnostic feedback allows the PLC CPU to detect open-load, short-to-ground, and thermal shutdown events without additional circuitry, enabling predictive maintenance. Compared to electromechanical relays, the ITS711L1FUMA1 offers 10x longer mechanical lifetime, silent operation, and faster switching speed.
推荐
24V Solenoid and Valve Drivers
Industrial solenoid and hydraulic valve switching demands high inrush current handling plus robust flyback protection. The ITS711L1FUMA1's 1.7A continuous per channel rating covers most industrial solenoid coils, and its 34V maximum load voltage handles inductive kickback at switch-off when paired with external freewheel diodes. The Smart SIPMOS technology integrates vertical N-channel MOSFETs that handle repetitive inductive switching events. Ground-referenced CMOS inputs let a 3.3V or 5V microcontroller directly control each solenoid without level-shifting. Built-in thermal shutdown protects the IC if a valve coil shorts or the ambient temperature exceeds the -40C to +85C industrial rating.
推荐
Building Management Relay Replacement
Building automation systems traditionally use electromechanical relays to switch lighting, HVAC dampers, and motorized valves. The ITS711L1FUMA1 replaces these relays with solid-state switches providing silent operation, longer lifetime, and built-in diagnostics. Four channels in a single PG-DSO-20-31 package reduce PCB footprint by approximately 70% versus equivalent 4-channel relay solutions. The 5V to 24V load range covers both ELV lighting control and 24V HVAC actuator power. CMOS inputs interface directly with building automation controllers (BACnet, Modbus, KNX transceivers). Status feedback enables centralized fault monitoring across distributed building systems.
推荐
Programmable Logic Controller (PLC) Discrete Outputs
PLC discrete output modules require high-density switching with diagnostic feedback to meet industrial reliability standards. The ITS711L1FUMA1 provides four independent high-side switches with per-channel current limiting and open-load detection, enabling IEC 61131-2 compliant output modules in a compact footprint. Its 1.7A continuous rating per channel meets the 0.5A to 2A typical industrial output requirement, and the integrated charge pump ensures full enhancement of the internal N-channel MOSFETs even at low load voltages. The PROFET Industrial series is qualified for factory automation environments with extended temperature ranges and high EMI immunity.
推荐
Industrial Machine Safety Interfaces
Safety-rated industrial outputs (e.g., emergency stop relays, safety door interlocks) benefit from the ITS711L1FUMA1's diagnostic feedback and embedded protection. The device's open-drain status output signals abnormal load conditions to the safety controller, enabling fail-safe detection of broken wires, short circuits, or overloaded outputs. While not itself safety-certified (SIL or Cat. rating requires additional qualification), the ITS711L1FUMA1 provides the hardware foundation for safety output modules with proper system-level redundancy. The -40C to +85C industrial temperature range suits factory floor environments.
推荐
12V Automotive Body Electronics
Although specified as PROFET Industrial, the ITS711L1FUMA1's 5V to 34V load range also covers 12V automotive body systems (lighting, mirrors, seat controls). The four-channel configuration replaces four discrete high-side switches or relays in body control modules, reducing PCB area and BOM cost. CMOS inputs interface directly with automotive microcontrollers. However, for production automotive designs, Infineon recommends the PROFET Automotive family (e.g., BTS series with AEC-Q100 qualification) instead - use ITS711L1FUMA1 only for non-safety automotive accessories or industrial environments where automotive-grade qualification is not required.

设计说明
Estimated: at full-load operation (4 channels active, 1.7A each, 24V supply into 12V load), total power dissipation is approximately 4 channels x 1.7A x (24V-12V) = 81.6W, which exceeds the PG-DSO-20-31 thermal budget. In practice, derate to no more than 2 channels active simultaneously at full load, or 4 channels at 50% duty cycle. Provide a minimum 1 square inch of copper pour under the exposed tab to maintain junction temperature below the 150C thermal shutdown threshold.
The PG-DSO-20-31 package has an exposed thermal pad (pin 20) that MUST be soldered to a PCB ground plane for proper heat dissipation. Use thermal vias (0.3mm diameter, 1mm pitch, 6-8 vias minimum) under the pad to conduct heat to inner copper layers. Place input bypass capacitors as close to the VS pins (14, 15) as possible - a 100nF ceramic plus 10uF electrolytic combination is recommended to handle load-step transients.
Do not exceed 34V on the VS pin - transients above this will trigger over-voltage protection and may damage the device. The CMOS inputs (IN0-IN3) are ground-referenced and accept 3.3V or 5V logic directly - do NOT drive inputs above 5.5V or below -0.3V as absolute maximum. When driving inductive loads (solenoids, valves, motors), add external freewheel diodes across the load to dissipate back-EMF energy safely.
Keep high-current output traces (OUT0-OUT3, VS) short and wide (at least 1mm width per ampere). Separate analog/digital ground from power ground if your design mixes signal and load circuits. The ST (status) pin is open-drain and requires an external pull-up resistor (10k to 100k typical) to your logic supply voltage. Avoid routing ST traces parallel to high-current outputs to prevent noise coupling into the diagnostic feedback path.
The CMOS input pins have internal pull-down resistors, so unconnected inputs default to OFF state. For fail-safe operation in safety-critical applications, do NOT rely on internal pull-downs - explicitly drive each input to a defined logic level. When PWM-switching the outputs (e.g., for LED dimming or motor speed control), limit switching frequency to below 1 kHz to avoid coupling switching transients into adjacent channels through the shared VS and GND pins.
