PMIC - Power Distribution Switches, Load Drivers

The BTS5460SFXUMA1 is a power distribution switch, load driver and voltage regulator integrated within one device. This product helps to monitor and protect power systems within a wide range of applications. It has enhanced current capability, reliable thermal protection, simplistic configuration and a highly immune EMC filter. This device is suitable for multiple types of safety critical applications within the automotive industry.

The BTS5460SFXUMA1 device features a simple but powerful 4-step configuration to offer a variety of protections and operations. The first step is setting the maximum load current. This can be used to protect the system against short-circuit due to excessively high load current. The second step is selecting the power on reset voltage. This can be used to send a power-on reset signal to the system on recovery after a power failure. The third step is selecting the open and close times. This allows the device to be configured to open or close in certain periods of time. Finally, the fourth step is setting the undervoltage lockout level. This step dictates at what voltage the device should turn off the output to protect the system from undervoltage damage.

The primary application field of the BTS5460SFXUMA1 is in the automotive industry and particularly in safety critical applications. These include driver, climate and comfort applications, or powertrain control units. Common safety critical applications include anti-lock braking systems, airbag modules, E-gas, cranking, idle speed control and power steering. The device is highly reliable and helps to ensure that these applications will be satisfied in a reliable manner.

The BTS5460SFXUMA1 works according to certain principles of operation. Firstly, it contains a power distribution switch which is used to selectively activate and deactivate power loads. The switch is internally protected by an accurate current sensing circuit, thermal protection, and an undervoltage lockout level. This allows the device to be operated in a safe and reliable manner. Secondly, the device contains a load driver which can be used to load or unload independently controlled outputs. The driver is highly efficient and together with the power distribution switch allows for multiple types of operations to be fulfilled. Finally, the device contains a voltage regulator which allows for an adjustable output voltage. This has enabled the device to be used in a variety of applications such as battery management systems and automotive lighting.

In conclusion, the BTS5460SFXUMA1 is a power distribution switch, load driver and regulator integrated within one device. It features simple but powerful 4-step configurations, a high degree of reliability, enhanced current capabilities and an immune EMC filter. The main application of this device is in the automotive industry, particularly in safety critical applications such as driver, climate and comfort applications or power train control units. The device operates according to certain principles of operation including power distribution switch, load driver and voltage regulator.
