BD45385G-TR Integrated Circuits (ICs)

PMIC - Supervisors

BD45385G-TR is a series of microcontrollers that are part of a power management integrated circuit (PMIC) supervisor family from ROHM Semiconductor. This series of microcontrollers is a supervising circuit used to monitor and control the power supply conditions of power management systems. By constantly monitoring the power supply, this device has the ability to detect any power supply instability and act to reduce or eliminate the instability before any malfunction occurs.

There are three main application fields for the BD45385G-TR series.First, it is used in battery-powered systems such as portable computing, gaming and consumer electronics. This series of microcontrollers is ideal for these applications as it is able to enable functions such as charging, level shifting and backup power.Second, it is used in power management in industrial applications. In industrial applications, the BD45385G-TR is capable of providing protection against overcurrent, overvoltage and undershoot, extending the life of the system.

The working principle of the BD45385G-TR series revolves around monitoring the condition of power lines and detecting power supply abnormalities. When a power supply abnormality is detected, it triggers an alarm or a restart, depending on the application and the target conditions. The monitor and control functions can be customized using the on-chip registers and the integrated watchdog timer. The watch dog timer can be set up to 4 seconds to reset the system and can also be used to monitor the system\'s response time.

Due to its superior power monitoring and control functions, the BD45385G-TR series is an excellent choice for mobile, consumer, and industrial applications. It offers excellent protection from power instabilities and is an efficient solution for supervisory applications.
