The BTS500801TEAAUMA1 is a versatile power management integrated circuit (PMIC) that enables efficient power distribution and driving of loads. It can be used in a variety of applications such as switching voltage regulators, control power to peripheral devices, and providing electronic overload protection.

Power Distribution Switches

The BTS500801TEAAUMA1 offers two power distribution switches. These are used for providing power to two separate power rails; one for general purpose applications and the other for high current applications or critical tasks. Both switches are capable of delivering up to 7A output current. The power switch outputs can be controlled separately by dedicated signal pins, by control logic generated by embedded fault detection and thermal management.

Load Drivers

The BTS500801TEAAUMA1 offers two load drivers. The first load driver is used for driving gate and base of NPN transistors, providing control current up to 120mA. The second load driver is for high current loads, providing up to 350mA peak current. The output voltage of the load drivers are adjustable using external resistors or potentiometers, and thereby allows for efficient control of the output current.

Fault Protection

The BTS500801TEAAUMA1 provides a variety of embedded fault protection features. It offers overvoltage protection, undervoltage protection, overload protection and thermal protection. The embedded circuit monitors the voltages and currents on the power rails as well as the temperatures of the power switch and load drivers to protect the circuit from damages. When one of the monitored conditions is out of the safe range, the BTS500801TEAAUMA1 will shut down the power distribution switch and/or load driver, preventing damage to the circuit.

Operation Mode

The BTS500801TEAAUMA1 can operate in either continuous or burst mode of operation. In continuous mode, the power switch is always ON and can deliver output current continuously. In burst mode, the power switch is ON for a given period of time determined by the external ON/OFF control signals and then turns OFF automatically. This mode of operation helps in reducing power dissipation and saving power.

Applications

The BTS500801 TEAAUMA1 PMIC is suitable for a wide range of applications, such as industrial control, automotive, and home appliances. It is ideal for providing power and control to loads and peripherals, providing robust overload and temperature protection. Its low power operating mode helps to conserve power and reduce dissipation.
