Infineon HITFET Series Power Switch IC, 3.8W Power Rating, 42V Maximum Supply Voltage - BTS3110NHUMA1
This power switch IC is a low-side automotive load switch designed to control multiple vehicle circuits from a single input. It operates across a wide temperature range and is intended for surface-mounted applications, providing compact power control suitable for automotive electrical systems.
Features and Benefits:
• Low on-resistance of 220mΩ reduces conduction losses
• Rated for up to 42V supply to handle vehicle electrical transients
• Operates from -40°C to 150°C for harsh environments
• Supports 1.4A operating current for moderate loads
• Four-pin SOT-223 package enables straightforward surface mounting
• Rated for up to 42V supply to handle vehicle electrical transients
• Operates from -40°C to 150°C for harsh environments
• Supports 1.4A operating current for moderate loads
• Four-pin SOT-223 package enables straightforward surface mounting
Applications
• Suitable for switching vehicle auxiliary loads and sensors
• Ideal for distribution to multiple low-side loads in cabins
• Used with 12V/24V systems requiring 42V transient margin
• Can be used for driving resistive and small inductive loads
• Suitable for compact ECU or module power management
