The BD45445G-TR is a power monitoring integrated circuit (PMIC) from ROHM Semiconductor. Supervisors are known for their ability to protect electronic systems from voltage, current and temperature over/under-conditions. The BD45445G-TR is designed for use in communications applications where low power consumption is important, such as cellular base stations, radio modems and cordless phones. The source voltage range of the BD45445G-TR extends from 1.3V to 36V, allowing the device to be used in a variety of systems. The BD45445G-TR enables supply lines to be monitored and controlled in these systems, ensuring safe operation and reliable performance.

The BD45445G-TR is a multi-channel PMIC. It has four monitoring channels: Vcc, LDO1, Ref1, and Ref2. These four channels allow for the monitoring of input voltage levels, output voltage levels, and temperature levels in the system. The data acquired by the monitoring channels is used by the BD45445G-TR to generate alarms, alerting the user of an over/under voltage, current, or temperature condition. The device also has an embedded system reset output, which can be used to reset the system when an alarm is issued.

The BD45445G-TR is capable of monitoring a wide range of input voltages. It supports input voltages from 1.3V to 36V, allowing it to be used with various system power sources. The BD45445G-TR also has an integrated voltage regulator. This voltage regulator enables the device to supply a stable voltage level for system components, ensuring that the system is operating under optimal conditions. The integrated voltage regulator can also be used to reduce system power consumption by regulating the supply voltage to one that is suitable for the system components.

The BD45445G-TR has a low power consumption, making it suitable for use in power-sensitive systems. The device can operate in three power modes: active, sleep, and stop. In active mode, the device is actively monitoring the system. In sleep mode, the device is only monitoring the system at a low frequency. In stop mode, the device is completely powered off, reducing system power consumption to near zero. This feature enables the device to be used in power-sensitive applications where low power consumption is a must.

The BD45445G-TR is also equipped with several safety features. These features include reverse polarity protection, short-circuit protection, and temperature protection. Reverse polarity protection prevents damage to the device if wrong power polarity is detected. Short-circuit protection prevents the device from being damaged if a short circuit occurs in the system. Temperature protection prevents the device from being damaged if the system exceeds an acceptable temperature level.

The BD45445G-TR is a low-power monitoring IC, designed for use in systems where low power consumption and reliability are essential. It has four monitoring channels, which can be used to monitor input and output voltages as well as temperatures. The device also features low-power operation modes, enabling it to be used in power-sensitive systems. In addition, the BD45445G-TR is equipped with several safety features, ensuring safe operation in the system.
