PMIC - Supervisors

The BD5223FVE-TR is a medium-or-low voltage reset detection voltage supervisor IC with reset and manually controlled reset. It has 4 functions including reset voltage detection, reset output, manual reset, and output enable. It is used in electronic systems and many products such as digital cameras and point-of-sale terminals.

Application Field

The BD5223FVE-TR can be used in a variety of applications where medium or low voltage reset detection is required. It is commonly used in automotive, industrial, consumer, medical and high-end audio/video controls. It is also an alternative to discrete components when a miniature and low profile solution is desired.

The BD5223FVE-TR has an integrated circuit and three pins which are used to set the voltage detection level, set the reset output level, and control the manual reset respectively. This makes it an ideal device for applications where space is limited, current consumption needs to be kept to minimum, and cost savings is desired. It is suitable for medium voltage systems ranging from 5V to 24V and low voltage systems ranging from 0.6V to 5V.

Working Principle

The BD5223FVE-TR is designed to detect and regulate the voltage via the voltage detection pin (VDET). When the voltage rises above the set level, the reset output pin (RSTOUT) is activated, causing a voltage reset in the system. This reset output is active-low and pulled up to VDD by an internal pull-up resistor.

The power input of the BD5223FVE-TR is connected to the system power supply rail, referred to as VDD, which is also connected to the voltage detection pin. When the voltage detection pin sets the desired voltage level, the reset output will be active-low and the system will reset. The manual reset pin is used to extend the reset duration of the system by controlling the reset output. An active-low on the manual reset pin will keep the reset condition active even after the voltage on the VDD pin goes back above the reset voltage.

In summary, the BD5223FVE-TR is an ideal supervisor IC for medium or low voltage reset detection. It is a compact and low cost device suitable for a variety of applications. It has four functions including reset voltage detection, reset output, manual reset, and output enable which make it to be a good choice for controlling reset signals in a variety of systems.
