The BD5355FVE-TR is an integrated circuit designed as a Power Management IC (PMIC) with an embedded and superfical supervisor, specifically targeted at mobile devices and any other application with low power consumption requirements and requiring a low-power logic voltage range.

The BD5355FVE-TR supevisor is configured to detect non-reset events related to specific power supply voltages, including overvoltage and undervoltage conditions. The supervisor also functions as an output enable (OE) control circuit and has two output enable pins that can be used to enable/disable the outputs of up to four independent power-management stages. When a fault condition is detected, the enable signals for the outputs are asserted Low, thus disabling all the power outputs.

The working principle of the BD5355FVE-TR supervisor is quite simple; it relies on a comparator circuit to detect over-voltage and under-voltage conditions across two voltage rails. When the voltage on either of the two rails exceeds the pre-defined thresholds, the output of the comparator circuit changes its state and triggers the output enable feature. The output enable feature then disables the outputs of the four independent power-management stages.

The primary application field of the BD5355FVE-TR supervisor is mobile devices where low power consumption is of utmost importance. The integrated supervisor allows for the efficient management of the power supply and enables the inputs of the four-power management stages to be enabled and disabled depending on the required power demand, thus enabling efficient and safe power management.

The advantages of the BD5355FVE-TR PMIC and supervisor include low quiescent current consumption, simple user interface, and robust capability to detect and flag faults. The BD5355FVE-TR supervisor is ideal for use in mobile devices and other applications such as automotive and industrial control systems, medical device and communication systems requiring low power consumption and accurate detection of fault conditions.
