BD4931FVE-TR is a power management integrated circuit (PMIC) supervisor that is designed primarily to control power between multiple voltage sources. It is often used to increase system reliability by providing power control or to enable external logic circuitry to monitor various power system conditions.

The BD4931FVE-TR provides an integrated real-time voltage monitoring and control for multiple power supply rails. It has the capability of controlling multiple output power supplies and can monitor up to 16 power supply rail voltages. It is a sturdy solution for the multi-rail power control needs due to its low power consumption, small footprint and high system reliability.

The BD4931FVE-TR is a digital power manager and control solution. It integrates several features that enable system control, including power on/off control, double-power-on control, voltage monitoring, and watchdog timer. It also offers temperature sensing, power fail detection and power fail latch-off functions. The BD4931FVE-TR provides many additional features that enhance system reliability and overall performance.

The BD4931FVE-TR’s primary function is to provide power monitoring and control to multiple voltage sources. It can control power on/off, voltage monitoring and enabling of external logic circuitry to monitor power system conditions. As a supervisor IC, the BD4931FVE-TR serves as a power supply monitoring and controlling device for the whole system. It is responsible for monitoring and controlling the power to each of the power supply rails, which can reduce power consumption and improve system reliability.

The BD4931FVE-TR also offers wide operating temperature range, from -40°C to 85°C. This broad operating temperature makes it ideal for various industrial application fields, such as embedded systems and portable devices. It is also suitable for automotive applications and other systems that require reliable power supply control and monitoring.

The BD4931FVE-TR has a built-in watchdog timer to monitor and control an external system. When the timer cycles, it generates a reset signal if the processor has not responded. This ensures that the system will not hang or fail due to software malfunctions.

The BD4931FVE-TR can support up to five independent output pins assigned to five independent power outputs. Each output pin can monitor, detect and control the corresponding output voltage. It can also detect power off, power-on, and power-fail conditions. Additionally, the application can also set high and low voltage thresholds on each power output for improved reliability, system control and power management.

The working principle of BD4931FVE-TR is simple. The IC acts as an interface between the system hardware and the processor, enabling the application to control the power to the system. It recognizes and monitors power-on, power-off and power fail conditions, and will send reset signals to the processor if the system fails to respond. It also supports temperature sensing and can detect power fail latching which will cut off power to the system in an undesirable condition.

The BD4931FVE-TR is a highly reliable and powerful supervisor power management integrated circuit for monitoring and controlling multiple power supply rails. It is compatible with various application fields, such as embedded systems, portable devices, and automotive. It has low power consumption and high system reliability, making it an ideal solution for integrated system power control.
