PMIC (Power Management Integrated Circuit) supervisors are important for modern electronic designs, as they provide control, monitoring and protection capabilities for integrated circuits. They are used to prevent system malfunction, manage supply voltages, and reduce power consumption. The BD48E54G-TR is a low voltage supervisor IC from ROHM. It is designed for use in single-supply systems, and provides protection for embedded microcontrollers, DSPs and other integrated circuits.

The BD48E54G-TR is uses a simple open-drain architecture to detect when a device’s supply voltage drops below a predetermined threshold. This enables it to indicate a fault condition, and can be used as a reset signal to protect against system malfunctions. It also includes a voltage monitor, which can be adjusted to a desired level to deny power to devices when they drop below a certain voltage. Additionally, its low current consumption allows MBDs to detect faults faster, and reduces the power consumption of the system.

The operating temperature range of the BD48E54G-TR is -40°C up to 85°C. It is available in a 14-SOP package, with a supply voltage range of 1.6V to 3.6V, and a power consumption of 0.6uA in normal mode and 0.1uA in low power mode. It also has a typical voltage monitoring accuracy of ±2%.

The main application fields of the BD48E54G-TR are power supplies, battery management, industrial automation, embedded systems, and automotive systems. It is commonly used to protect sensitive electronics from over-voltage, under-voltage and fault conditions. In power supplies and battery management systems, it is used to reduce system malfunction and save power by turning off devices when their power supply drops below a certain voltage. In industrial automation and automotive systems, it is used to activate safety systems when the supply voltage drops below predetermined threshold limits.

The BD48E54G-TR usually operates in two modes: normal mode and low power mode. In normal mode, the voltage monitor is always on, using 0.6uA of current. This enables the supervisor to monitor the supply voltage at all times, and provide real-time protection. In low power mode, the voltage monitor is switched off, reducing the current consumption to 0.1uA. This is useful when the system needs to be shut down or in standby mode.

The BD48E54G-TR is a versatile, low power supervisor IC, which provides protection, monitoring, and control capabilities for single-supply systems. Its wide operating temperature range and low current consumption make it ideal for use in power supplies, battery management, industrial automation, embedded systems, and automotive systems.
