PMIC (Power Management Integrated Circuits) has become an important technology in modern electronic systems, and its importance is increasing as the demand for high efficiency and low power consumption is also increasing. The BD48K55G-TL is a power management integrated circuit (PMIC) which is used for voltage supervisors and allows for a system-wide reseting. It implements all necessary functions for a reliable power system, and it is the perfect solution for systems that require the reset of multiple system components due to a power failure.

The BD48K55G-TL voltage supervisor provides a 4-channel reset system which is able to detect and reset power supply levels, power-on signals and system reset pins. This is accomplished by various voltage detection blocks, which each output an internal signal to the reset generator. The reset generator generates a reset pulse based on the external signal, and then basically affects the reset of the entire system. The reset can be delayed if desired, which is useful when the power is not necessary until a certain time in the system.

The BD48K55G-TL voltage supervisor also allows external reset switch input, and the reset signal is generated when the external switch is pressed. In addition, the BD48K55G-TL features a power good output signal, indicating when the power is applied correctly and is ready for operation. It also has an internal timer circuit, which emits a reset signal if the power good signal has been absent for an adjustable time.

The BD48K55G-TL has a number of applications, such as embedded systems, sensor networks, industrial automation and commercial automation. The voltage supervisor can also be used in healthcare, automotive, smart home and other fields. It provides a reliable system for resetting the power level, making it an excellent choice for applications that require efficient and reliable power management.

The working principle of the BD48K55G-TL is simple. This voltage supervisor utilizes a reset generator and four voltage detection blocks to detect power supply levels, power-on signals and system reset pins. When a voltage detection block senses an abnormal voltage or power-on signal, it sends an internal signal to the reset generator. The reset generator then generates a reset pulse based on dual-tone-mute-xor (DTMX) scheme and then sends it to the system for resetting.

Additionally, the BD48K55G-TL also has an internal timer circuit which starts to count the time once the power good signal is received. When the timer reaches its adjustable time, the reset generator will be triggered and the power good signal will be sent to the system. The reset generator is triggered by the detection blocks and the timer circuit, which allow the power good signal to be sent to the system only when the system is ready.

Overall, the BD48K55G-TL is a powerful and reliable supervisor PMIC that can provide a reliable and efficient way to reset the system in a wide range of applications. It features a reset generator and four voltage detection blocks, which can detect abnormal voltages or power-on signals and then reset the system accordingly. Additionally, it also has an internal timer circuit which can indicate when the power is ready and generate a reset signal if the power is absent for a certain adjustable time. All of these features make the BD48K55G-TL an excellent choice for applications that require efficient and reliable power management.
