PMIC (Power Management Integrated Circuit) is a type of integrated circuit designed to provide electrical power from the power system\'s main power source to the peripheral components of a computer. It contains different kinds of power management components such as voltage regulators, power supply controllers, and voltage detectors. One popular type of PMIC is a Supervisors, which is used to supervised, monitor and detect the activity of digital components.BD45291G-TR is one type of Supervisors from Rohm Semiconductor. This device is designed to provide reliable power supply to memory, logic and similar types of digital applications. It allows simple, cost-effective power solution with low power consumption and several features such as fast start-up, built-in voltage monitor, voltage detect and brown-out reset.Application fieldThe BD45291G-TR is specifically designed for memory, logic and other digital applications. It can provide a reliable power supply control while ensuring low power consumption. It is suitable for various applications such as Internet of Things (IoT), automotive, consumer, smart appliances, industrial, home appliances, and communication. It is also used in digital systems such as data processing, audio, video, motor control and lighting systems.Working PrincipleThe BD45291G-TR Supervisors is an integrated power management device that regulates and monitors the power supply in digital systems. It is designed to detect abnormal supply voltage levels and to carry out reset operations when required. It consists of a Voltage Detector (Voltage Monitor) and a Voltage Detect Block. The Voltage Detector is responsible for detecting the abnormal supply voltage levels. It will issue a detection signal if any fault is detected in the supply voltage. The Voltage Detect Block will then reset the system to prevent any damage if an abnormal voltage is detected.The BD45291G-TR also includes a Delay Time Block, Start-Up Circuit, Brown-Out Reset Block and an Output Control Block. The Delay Time Block is used to control the timing of reset operations. The Start-Up Circuit is responsible for powering up the system. The Brown-Out Reset Block is used to detect and control excess voltage levels while the Output Control Block is used to control the output of power supply.The BD45291G-TR also has a VDD supply input range of 2V to 20V and a maximum power supply current of 2mA. The operating temperature range is from -40℃ to +125℃. The device also supports additional features such as digital input filter, power supply reset output and low power reset output.ConclusionBD45291G-TR from Rohm Semiconductor is a Supervisors designed for memory and logic applications. It is an integrated power management device that provides reliable power supply control for digital systems with low power consumption. It offers a wide range of features including delay time control, start-up circuit, built-in voltage monitor and brown-out reset. It has an operating temperature range of -40℃ to +125℃ and a VDD supply input range of 2V to 20V. It is suitable for various applications such as Internet of Things (IoT), automotive, consumer and communication.
