Working Principle

The BD46401G-TR is a supervisor device with active protection and precise power-supply monitoring capability. It can monitor the voltage status of a system, detect the voltage threshold events, and perform appropriate actions upon detecting the events. It has a built-in voltage threshold window circuit, resettable timer, and low-power shutdown circuit.

The voltage threshold window circuit is designed to detect any voltage deviation beyond an adjustable threshold range. The adjustable threshold range can be set between 2.8 V and 6 V. When the voltage deviation exceeds the adjustable threshold range, the voltage threshold window circuit will generate an alert signal to the resettable timer circuit. The resettable timer circuit is designed to prevent false reset events and prolong the system\'s operation life. Once the alert signal is triggered, the resettable timer will reset the system and perform a low-power shutdown.

The BD46401G-TR\'s low-power shutdown circuit is designed to reduce unnecessary power consumption and prolong the battery life. It will activate when the voltage falls below the adjustable reset threshold, and will reduce the power supply to minimal current levels. It also will monitor the system constantly and maintain the voltage within the threshold window.

The BD46401G-TR is a power management integrated circuit with active protection and precise power-supply monitoring. It can provide accurate system-level monitoring and protection, enabling the device to withstand power disturbances, prevent system malfunction, and prolong operation life. It is suitable for a wide range of applications and provides a low-power, reliable solution for power management.
