BD5346G-TR

The BD5346G-TR is a voltage supervisor IC that helps keep critical functions, such as resetting MCUs and system power on/off, operating correctly. It is specialized for applications that require reliable power supply monitoring and control. As a PMIC (Power Management IC), the BD5346G-TR autonomously manages the power supply to a system by using two threshold detections, one for detecting the power supply voltage and the other for detecting the power supply current. With its onboard low current consumption, low power consumption, and one-shot pulse generating circuit, the BD5346G-TR can monitor the power supply to any MCU-based system.

Features of BD5346G-TR

The BD5346G-TR is feature-rich and includes various benefits. Its built-in amplify and low-current consumption circuits allow it to accurately measure and detect the power supply voltage and current. Its one-shot generating circuit produces a single pulse with the press of a switch. The IC also includes a power-on-reset circuit, which can reset the system when the power supply voltage is below the preset level. Finally, the BD5346G-TR also includes an over-current detection function, which will instantly detect any momentary closure of the current, such as when connecting external power supplies.

Applications of BD5346G-TR

The BD5346G-TR has several potential applications including automotive, industrial, and consumer electronics. In automotive applications, the IC can be used to accurately monitor the power supply for components such as electric modules and ignition systems. In industrial applications, it can be used as a voltage supervisor for power supplies and fans. The IC could also be used in consumer electronics to monitor the power supply for items such as routers and base stations.

Working Principle of BD5346G-TR

The BD5346G-TR works by setting two thresholds, one for detecting the power supply voltage, and the other for detecting the power supply current. When the voltage or current falls below the preset threshold level, the IC will generate a low voltage pulse. This pulse can be used to reset the system power or to alert other circuits for attention. The IC has an onboard Amplifier, which amplifies the ascending or descending order of analogue signals, thereby enabling it to detect the smallest changes in voltage or current.

Additionally, the IC has an over-current detection circuit that monitors the current flow and can detect any momentary closure of the current, such as when an external power supply is connected. Finally, the IC includes a one-shot pulse generating circuit that produces a single pulse when triggered. This pulse can be used to increase or decrease the power supply on the system, such as when turning on or turning off the power supply.

Conclusion

The BD5346G-TR is a specialized voltage supervisor IC that is designed for applications where reliable power supply monitoring and control is required. Its features, such as its low current consumption, low power consumption, and one-shot pulse generating circuit, make it an ideal choice for a variety of applications, including automotive, industrial, and consumer electronics. Its working principle is based on setting two thresholds, one for detecting the power supply voltage and the other for detecting the current. When the voltage or current falls below the preset threshold level, the IC will produce a low voltage pulse.
