Introduction

BD45355G-TR is a highly integrated device developed by ROHM Semiconductor and is designed to provide power management to mobile and IoT systems. It contains one supervisor, six identical ON-OFF controllers and several static state power control switches. All components are integrated on a single chip, which makes the device very compact and power efficient. This device also eliminates the need for external components, resulting in a smaller form factor and reducing cost. Moreover, it supports a wide operating voltage range, making it suitable for many applications.

Application Field

BD45355G-TR is designed primarily for applications including mobile phones, tablet PCs and other mobile devices, as well as systems for IoT applications in smart home, automotive, industrial and other such domains. More specifically, its power control functions make it suitable for applications such as system shutdown liners, voltage level detections, power switch and over-voltage protection. Likewise, its low power consumption, small size and high integration capabilities make it an ideal choice for battery-powered systems where board space is limited.

Working Principle

BD45355G-TR is a device that works on the principle of supervisor ICs, which are designed to monitor power supply voltages and trigger system reset and other safety functions when out of range conditions occur. It has six identical ON-OFF controllers, each consisting of a supervisor, an input comparator and an output buffer. The input comparator can be configured to trigger system reset or other outputs upon detection of out-of-range conditions while the output buffer controls the output according to the input signal.

The supervisor’s main function is to monitor the input voltage, and detect out-of-range conditions such as over-voltage and under-voltage. When one of these conditions is detected, the controller will activate the output buffer, triggering the necessary system reset or other safety functions. Additionally, the static-state power control switches can be used to switch the power to external parts such as sensors, displays and peripheral components, thus eliminating the need for external power switches.

Conclusion

In conclusion, the BD45355G-TR is a highly integrated device from ROHM that is designed for power management in mobile and IoT systems. It includes one supervisor, six identical ON-OFF controllers and several static state power control switches, which allow system reset and other safety functions, as well as the powering of external parts without the use of external switches. The device is highly power efficient and small in size, making it an ideal choice for battery powered applications where board space is limited.
