Infineon BTS441RG Series Power Switch IC, 41V Maximum Operating Supply Voltage, 21A Maximum Operating Current - BTS441RGATMA1

This power switch IC is a high side switch designed for automotive applications. It features a compact TO-263 package measuring 10 x 9.25 x 4.4 mm, making it suitable for surface mounting. With a maximum operating voltage of 41V and a current capacity of up to 21A, this device integrates essential protection features, including over-current, short circuit, and thermal shutdown.

Features & Benefits

• Low on-state resistance of 37mΩ reduces power loss

• Integrated over-current protection enhances safety and reliability

• Fast demagnetisation of inductive loads improves performance

• AEC qualified for enhanced automotive reliability and standards

Applications

• Suitable for automotive requiring high voltage switching

• Ideal for driving inductive loads, such as motors and lamps

• Utilised in microcontroller compatible power switching

• Often used for various resistive and capacitive loads

What thermal considerations should be taken into account when using this device?

The power switch incorporates thermal shutdown protection to prevent overheating. Operating within the specified temperature range of -40°C to +150°C ensures efficient performance, especially in demanding environments. Always ensure adequate heat dissipation to maintain optimal operation.

How does the over-current protection feature function?

The IC includes integrated over-current protection that limits the load current to prevent damage during fault conditions. If the current exceeds the specified threshold, the device automatically reduces output, facilitating safe operation without manual intervention.

Can this switch handle inductive loads effectively?

Yes, it is designed for fast demagnetisation of inductive loads, which ensures efficient operation when turning loads on and off. This feature is particularly beneficial for applications involving motors or solenoids, where inrush currents can be high.
