ITS4141NHUMA1 - 700mA Smart High-Side Switch | Infineon PROFET
MPN: ITS4141NHUMA1 ✓ فعالITS4141NHUMA1 جائزہ
What is a high-side power switch? A high-side power switch is a type of power distribution switch (sub-category: load driver) that sits between the positive supply rail and the load, controlling current flow by turning the integrated MOSFET on and off in response to a logic-level input. Within the broader taxonomy, the high-side switch belongs to: PMIC -> Power Distribution Switch -> Load Driver -> High-Side Switch. Infineon's PROFET family is the industry-leading implementation using a vertical N-channel FET for low R_DS(on) and high energy robustness.
Key features include short-circuit protection with current limitation, overload protection, overvoltage protection including load-dump, undervoltage shutdown with auto-restart and hysteresis, plus an open-drain status diagnostic pin. The 200 mΩ R_DS(on) at 25 °C minimizes conduction losses, while the integrated charge pump drives the gate of the N-channel FET for true high-side switching with a standard 3.3 V or 5 V CMOS logic input. PG-SOT223-4 provides a low thermal resistance path via the central tab, enabling continuous 700 mA operation without external heatsinking.
The architecture is built on Infineon's Smart Power technology - a vertical DMOS output stage with monolithic CMOS control logic. The diagnostic pin reports open-load, overtemperature, and overcurrent events back to the microcontroller, while the auto-restart behavior allows the part to recover automatically once a fault clears, reducing firmware complexity in PLC and process-control applications.
Typical applications include 24 V industrial PLC digital outputs, factory-automation I/O modules, sensor and actuator power distribution, building-automation relay drivers, and battery-protected low-side-of-24V systems. The wide V_S range with load-dump tolerance makes it especially suited for 24 V truck and bus body-controller applications.
When designing with this part, respect the 700 mA continuous current limit and place the tab solder pad on at least 1 cm² of copper pour to keep R_thJA low enough for the SOA. The status pin requires a pull-up resistor and is open-drain; ensure input transitions are below 5 V CMOS thresholds for noise-immune switching.

ITS4141NHUMA1 کے لیے موزوں ہے 6 ایپلیکیشنs: 24 V PLC Digital Output Module, Industrial Sensor Power Distribution, Building Automation Relay Driver, 24 V Truck / Bus Body Controller, Process Control Valve Actuator, Battery-Backed 24 V System Power Switch.
24 V PLC Digital Output Module
The ITS4141NHUMA1 is purpose-built for 24 V PLC digital output cards where each channel must switch a solenoid, relay coil, or indicator lamp to ground-referenced loads. Its 200 mΩ typical R_DS(on) at 25 °C keeps conduction loss below 0.1 W per channel at 700 mA, and the -10 V to 48 V V_S range absorbs inductive kickback and 24 V load-dump transients without external TVS clamps. The open-drain status pin feeds back to the PLC SoC for wire-break and overload diagnostics, satisfying IEC 61131-2 industrial I/O requirements. Recommend pairing with a TLE4296 5 V LDO for MCU rail and a BTS3000SL for higher-current outputs.

Industrial Sensor Power Distribution
In factory-automation I/O nodes, the ITS4141NHUMA1 powers 4-20 mA loop sensors, proximity switches, and encoder supplies from a shared 24 V rail. Each output's current limit (around 0.7-1.5 A depending on temperature) protects the harness against sensor short circuits, while the undervoltage auto-restart with hysteresis allows clean recovery after brownout events. The 200 mΩ R_DS(on) drops only ~140 mV at 700 mA, preserving compliance headroom for the sensor's regulated supply. The PG-SOT223-4 footprint is ideal for high-density I/O cards where multiple switches must share a small PCB area.

Building Automation Relay Driver
The ITS4141NHUMA1 drives 24 V coil relays and contactor coils in HVAC, lighting, and access-control panels. Its 700 mA continuous rating handles most small-signal relays directly, while the open-drain status pin can be used to confirm the relay actually pulled in (via coil current sense). Load-dump tolerance to 48 V protects the switch from the inductive kick produced when the relay de-energizes, and the auto-restart on thermal shutdown prevents latched fault conditions during commissioning.

24 V Truck / Bus Body Controller
The ITS4141NHUMA1 is widely used in 24 V commercial-vehicle body controllers where it switches lighting, door locks, mirror heaters, and HVAC actuators from a 24 V truck battery bus. The -10 V to 48 V V_S rating covers jump-start (24 V -> 28 V), load-dump (up to 48 V per ISO 7637-2), and reverse-battery (-10 V) conditions without external protection. Its 700 mA continuous and ~1 A peak (with thermal foldback) suit most cabin loads, and the diagnostic pin reports open-load wiring faults to the BCM ECU.

Process Control Valve Actuator
In process-control valve assemblies and small solenoid valves, the ITS4141NHUMA1 provides the high-side switch for 24 V DC solenoids controlling fluid or pneumatic flow. The 700 mA rating suits standard 5-10 W valve coils, and the short-circuit current limit protects wiring in hazardous-area enclosures. Open-drain status confirms the valve is actually energized - critical for fail-safe system diagnostics. The -40 °C to +85 °C operating range handles outdoor and refrigeration installations.

Battery-Backed 24 V System Power Switch
The ITS4141NHUMA1 acts as a load-disconnect switch on 24 V battery-backed systems such as UPS, security panels, and emergency lighting. Its low 200 mΩ R_DS(on) minimizes parasitic drain on the battery when the system is in standby, while the wide V_S range and reverse-battery tolerance protect against wiring faults. The auto-restart on undervoltage prevents lockout when the battery recovers. Pair with the ITS4141N as a primary switch and a Schottky diode for reverse-current blocking if required.

ڈیزائن نوٹس
Estimated: at 700 mA continuous, R_DS(on) 200 mΩ, and V_S = 24 V, conduction loss is P = I²R = 0.7² × 0.2 = 0.098 W; with thermal foldback the PG-SOT223-4 (θJA ~80 K/W on 1 cm² copper) sustains this comfortably. However, during a short-to-ground the current limit engages at ~1-2 A for milliseconds and the part dissipates P_short = I_lim × V_S. Always solder the central tab to a continuous copper pour (≥1 cm²) to keep R_θJA low and avoid thermal shutdown on inductive kick recovery.
Place the status pin pull-up resistor close to the MCU GPIO to minimize noise pickup on long traces. Add a 100 nF ceramic decoupling capacitor directly on the V_S pin to the tab, plus a 1 µF bulk cap on the shared 24 V rail. The IN pin has an internal pull-down, but if the input trace runs more than 25 mm in electrically noisy industrial environments, add a 1 nF filter cap to ground to reject 50/60 Hz and motor-commutation EMI. Keep the ground return path directly under the V_S trace to minimize parasitic inductance in the discharge loop.
Do not float the input pin - if left open the part defaults to OFF (internal pull-down) but an open trace can pick up noise and self-trigger the output. Do not exceed the 48 V absolute maximum on V_S even momentarily - load-dump on a poorly-regulated 24 V truck battery can spike well above 48 V. The status pin is open-drain and requires a pull-up; never tie it directly to V_S without a current-limiting resistor. Finally, when paralleling multiple ITS4141NHUMA1 outputs to a single load, ensure all input pins are driven simultaneously to avoid circulating current between channels.
Route the high-current OUT trace (drain tab) on the top layer with a wide trace or polygon pour - the tab is the main thermal path. Use thermal vias under the central tab to inner-layer copper spreads. Place the input and status traces on the opposite side of the board from the V_S/OUT loop to minimize capacitive coupling. If the part sits near a switching converter, keep at least 5 mm clearance between the ITS4141NHUMA1 ground pour and the converter's switching node to avoid ground-bounce false triggering of the input comparator.
