The BTS6144B is a 4 channel high side power distribution switch specifically designed to control inductive loads, such as motors and solenoids. The device has an internal power-dc/dc converter and a low output voltage, thus enabling it to control automotive applications. It also features over-temperature protection over temperature control with hysteresis, to ensure safe and reliable operation. The device is split into two sections; one is the power side, and the other is the signal side.

In the power side, it consists of 4 N-channel MOSFETs, with the switch being controlled by an 8-bit logic controlled by a logic interface. In order to enable the device to control inductive loads, the device provides a current-limiting feature. When the activated load current exceeds the defined value, the device reduces the voltage and reduces the power dissipation generated by the load current.

The signal side consists of an 8-bit serial peripheral interface (SPI) which provides control of the actuating channels. The SPI is protected by an integrated cipher engine and an on-chip ECC controller, which ensures the data integrity and security of the transmission process. The device supports pre-defined SPI commands, allowing an easy and straightforward way to control the device.

In addition, the device is designed to operate in both extended temperature ranges and is able to operate up to 125°C, making it suitable for automotive and industrial applications. With the addition of ESD protection and a variety of protection features, it offers reliable operation even in the most challenging of environments.

The primary application field of the BTS6144B is in controlling inductive loads in automotive and industrial applications. It provides current-limiting and over-temperature protection features, enabling it to reliably control these type of loads. Furthermore, its 8-bit SPI provides an easy way to control the device. With its operating temperature range and reliability features, the BTS6144B is a great choice for automotive and industrial applications.
