The BTS6123P is an integrated power distribution switch and load driver aimed at load switching in applications with high inrush current. This device was designed to provide maximum power savings due to dynamic, efficient load switching and limited internal power consumption. In addition, the device features over-temperature, over-current and over-voltage protection.

The BTS6123P can be used in an array of applications and industries, such as automotive, motor control, smart meter, home appliance, lighting, and industrial applications. This IC is an ideal choice for intelligent and high current load switch control in power management systems, including motor control and power conversion applications.

Working Principle

The BTS6123P is composed of an integrated low side power MOSFET and an N-Channel MOSFET. It provides a self-oscillating circuit for load switch control and protection.

The BTS6123P operates in two modes - static and dynamic. In static mode, the low side MOSFET is closed and the load can be switched with minimal power consumption. In dynamic mode, the MOSFET switches rapidly and the load is switched much more efficiently. This rapid switching reduces the current surge or “inrush current”, which prolongs the life of the power device.

The BTS6123P also features over-temperature, over-current and over-voltage protection. The on-board temperature monitoring circuit is used to detect temperature changes and activate the thermal shutdown circuit to protect the device. The over-current protection circuit detects sharp current spikes and activates the protection circuit to disconnect the load from the power supply. In addition, the over-voltage protection circuit monitors the voltage of the power supply and activates the protection circuit to disconnect the load if the voltage exceeds the pre-set threshold.

The BTS6123P also features a programmable rise time control to manage the current surge and gradually turn on the power supply. This helps to reduce stress on the power device and protect it from damage. Finally, the device also features integrated boot voltage protection to prevent unnecessary current flow when the power device is switched off.

Conclusion

The BTS6123P is a versatile IC designed for power distribution switch and load driver applications. It is suitable for a variety of industries and applications such as automotive, motor control, smart meters, home appliance, lighting, and industrial applications. Its integrated features such as over-temperature, over-current and over-voltage protection, programmable rise time control, and boot voltage protection make it an ideal choice for intelligent and high current load switch control in power management systems.
