Power Distribution Switches, Load Drivers

The BTS5012SDAAUMA1 is a power Distribution Controller (PDC) integrated circuit (IC) designed to provide reliable power control in a variety of applications. It is a versatile PDC, capable of handling loads from a few hundred mA to several amps. It offers integrated over-current protection and real-time, automatic current sharing between all paralleled loads.

The BTS5012SDAAUMA1 can be used as a self-contained, low-noise, high-current switching system in a variety of applications. It is suitable for a range of power supplies, including dc-dc converters, linear regulators, and flyback supplies. The device is also suitable for use in automotive systems and other power-sensitive applications.

Features

• Wide output voltage range of 6 to 44 V
• High current capability up to 10 A
• Programmable switching frequency of 4 kHz to 200 kHz
• Integrated over-current protection
• Soft-start feature for optimized switching performance
• Integrated thermal monitoring
• Supports both active and passive current sharing

Working Principle

The basic working principle of the BTS5012SDAAUMA1 PDC is) to continuously monitor the load current of the switching output and, when necessary, to reduce the available output current to avoid over-current protection. This is achieved by using a PWM-type switching regulator architecture, where the output current iscontrolled by repeatedly switching the voltage on and off in a given time interval. The output voltage is kept constant through a feedback loop to an analog-to-digital converter (ADC) that measures the output voltage. When the output current is above the device\'s over-current protection threshold, the PDC will switch off briefly and reduce the output current until the threshold is no longer exceeded. This process is repeated continuously and helps to avoid over-current conditions and keep the system stable.

Applications

The BTS5012SDAAUMA1 PDC is suitable for a wide range of applications, including dc-dc converters, linear regulators, and flyback supplies. It can be used to provide over-current protection, current sharing, and optimized switching performance in automotive systems, industrial applications, and consumer electronic devices.

The device is well-suited for high-current applications, such as high-power LED lighting, renewable energy such as solar panels, and for industrial control systems. The integrated thermal monitoring feature allows for improved system reliability and network security. The wide output voltage range, high current capability, and low noise make the BTS5012SDAAUMA1 PDC an ideal choice for a variety of industrial and consumer applications.
