The BD45281G-TR is a Supervisors Power Management Integrated Circuit (PMIC) from the ROHM Semiconductor\'s BD45281G-TR series. It is a high-performance device that is designed for use in embedded systems and other applications requiring an efficient and reliable supervisor. The device is packaged in a compact (SOP8) form factor, making it suitable for a wide variety of applications.

The BD45281G-TR is ideal for applications such as board power reset, power-on reset, brown out detection, and as a clock monitoring circuit. This device monitors and controls up to 8 power input signals and provides a reset signal to the system. It also provides power control, system monitoring and reset functions including watch dog timer, manual reset input, and programmable reset output polarity. The device also features a wide power supply range, low power consumption and mounting area reduction.

The BD45281G-TR features a two-level detection that monitors the system\'s power supply state. It features an automatic or manual reset output, actively controlling the reset of the system. From the initial power-on reset to any other reset event, the device ensures the proper reset sequence for the system. The BD45281G-TR can help to protect the system from power-on reset, brownout condition, and overvoltage conditions. Additionally, the watchdog timer allows for monitoring the system state and resetting it in the event of a system fault or irregular reset condition.

The device supports both 3.3V and 5V input power supply voltages, and also has an adjustable reset voltage threshold. The device has an adjustable reset output delay feature, which makes it versatile for different applications. This feature allows the user to choose the appropriate reset delay according to the system requirement. The adjustable switchover voltage (reset voltage) and reset output time ranges enable the design engineer to adjust the reset timeout range and the reset voltage according to the specific application requirements. The programmable PWON3 reset output level can be used to light an LED to indicate the system state.

The BD45281G-TR is suitable for applications that require an efficient and reliable supervisor such as embedded systems, security applications, industrial controllers and remote control systems. It is easy to configure and requires minimal external components. The device can be used in a wide range of applications including automotive systems, solar controllers, medical equipment, and home appliances.
