The BD46322G-TR is a PMIC - Supervisors device from ROHM Semiconductor. It is designed to provide an accurate monitoring of a power supply voltage in applications such as consumer, industrial, and automotive electronics. The device is used to detect an increasing voltage, a decreasing voltage, or an overcurrent condition in the power supply system. When one of these conditions occurs, it will trigger an interrupt, allowing the system to take action to maintain a safe and reliable voltage level.

The BD46322G-TR is designed to operate at input voltages ranging from 1.02V to 5.5V. It has a maximum output current capability of 20 mA, and is able to detect both increasing and decreasing voltages with a resolution of 5 mV. The device is available in a surface-mount 7-pin LTSSOP package, and is compliant with the RoHS directive.

The BD46322G-TR includes various integrated protection features that protect the system from overcurrent, overvoltage, and undervoltage conditions. The device also includes an innovative overtemperature protection circuit that prevents the device from overheating and damaging the system. Additionally, the device includes an adjustable power-saving mode that reduces power consumption when the device is in a low-power state.

The device is suitable for use in a range of applications, including automotive electronics, digital home appliances, televisions, set-top boxes, portable devices, and industrial control systems. It also can be used in devices such as battery-powered systems, and computer-controlled systems.

To operate, the device monitors the power supply voltage using an internal voltage reference. When the power supply voltage exceeds the set value, the device will initiate an interrupt signal. This signal can then be used to trigger an action to maintain safe and reliable voltage levels.

When an increasing voltage is detected, the device will activate a timer circuit. This will signal the system to take proactive action before the voltage exceeds the set value. The time delay can be adjusted to reduce unnecessary intervention. In addition to this, the device also has a comparator that can be used to detect a decreasing voltage.

The BD46322G-TR also includes an overcurrent detection circuit. This circuit will monitor the power supply current and will trigger an interrupt when the current is higher than the set value. The interrupt can then be used to shut off the power supply or take action to limit the current.

Overall, the BD46322G-TR is a reliable and versatile PMIC - Supervisors device that is suitable for a wide range of applications. The device is designed to accurately monitor power supply voltage and detect overvoltage, undervoltage, and overcurrent conditions. Its integrated protection features and adjustable time delay provide flexibility and ensure system safety. The device is available in an easy-to-use 7-pin LTSSOP package, and is RoHS compliant, making it an ideal choice for use in modern electronics.
