Infineon High Side Power Switch IC 4-Pin SOT-223, High Side Topology, 1.7W Power Rating, 60V Max Supply Voltage BTS4140NHUMA1

Infineon BTS4140NHUMA1 is a high side power switch IC featuring a 1.7W power rating and supports a maximum supply voltage of 60V, housed in a compact 4-pin SOT-223 package designed for surface-mount applications. This device provides a robust and efficient solution for automotive and other low-voltage platforms requiring centralized switching control.

The IC operates with a single input controlling five independent outputs, simplifying the control of multiple loads in automotive electrical systems. Its 3000mΩ switch on resistance minimizes conduction losses for energy-efficient operation, while the 200mA operating current supports moderate load currents.

With a minimum supply voltage of 4.9V, this switch IC ensures reliable startup even at low voltages. Its wide ambient temperature range from -40°C to 150°C allows it to operate reliably in harsh automotive environmental conditions. The package dimensions of 6.5mm length, 3.5mm width, and 1.6mm height facilitate compact PCB layouts.

The BTS4140NHUMA1 device integrates essential short circuit protection and thermal endurance features to maintain performance and safety in demanding conditions. It is ideally suited for control modules that require a single input to switch multiple loads such as resistive and small inductive types.

Designed to meet automotive AEC standards, this power switch IC is widely used in aftermarket vehicle accessory distribution systems and other industrial or laboratory applications that require reliable high-side switching capabilities on a compact footprint.

The device supports high-side switching topologies used extensively in automotive load control. Single input controls five outputs, enabling efficient multi-load management. Low Rds(on) of 3Ω reduces energy losses under load conditions.

Thermally robust with maximum operating temperature rated at 150°C. Compact 4-pin SOT-223 package allows easy surface mounting and integration on PCBs. Supports a wide supply voltage range from 4.9V to 60V. Automotive AEC standard certified.

Suitable for switching resistive and modest inductive electrical loads. Provides built-in protection, ensuring safety and reliability in automotive environments.
