PMIC (Power Management Integrated Circuit) supervisors are a kind of power-management integrated circuits (PMICs) that provide resettable protection or monitoring functions for a wide range of electronic products. The BD5235FVE-TR is one such PMIC supervisor that can provide stable reset and reset protection to many different applications. It is manufactured by Richtek, a supplier of advanced analog and mixed-signal semiconductor solutions.

The BD5235FVE-TR is designed to detect supply voltage fluctuations and provide stable reset signals to a system’s power management unit (PMU). This ensures that all parts of the system remain safe from overvoltage and overcurrent. The chip also features adjustable reset threshold voltage with positive going or negative going edge triggering. In addition, it also has internal pull down and pull up resistors that help eliminate external surges and help stabilize the output.

The working principle of the BD5235FVE-TR is based on its ability to detect voltage fluctuations and produce reset signals in response to those fluctuations. The chip utilizes dual voltage comparators with an adjustable threshold range between 1.625V and 5.875V set by the RESET_VB pin. The comparators output a logic high signal when the input voltage rises or falls beyond the threshold voltage. This logic high signal is then buffered by the internal OR gate and then driven to the RECON pin for resetting.

The BD5235FVE-TR is used in applications such as CPU core voltage monitoring, automotive power supply monitoring, and thermal protection. Its stable reset signals are particularly useful for protection against various overvoltage and overcurrent threats in automotive systems. Its wide range of adjustable threshold settings makes it suitable for different kinds of applications. The chip can be used to detect sudden spikes or drops in voltage, and then initiate a reset signal to protect vital components from damage.

The BD5235FVE-TR also features under-voltage lockout (UVLO) functionality. This feature prevents the chip from being activated until the input voltage is greater or equal to the set UVLO threshold voltage, which is set by the UVLO_BG pin. This ensures that the chip does not activate until the required level of power is supplied to the system. Furthermore, the chip also has low quiescent current that helps conserve power.

The BD5235FVE-TR is a high performance PMIC supervisor suitable for many applications. It offers adjustable threshold levels with positive or negative going edge triggering, and its under-voltage lockout feature helps save power. The chip’s stable reset signals are highly beneficial for protecting against overvoltage and overcurrent issues in automotive and industrial systems. Moreover, its wide range of adjustable settings make it suitable for a variety of different applications.
