Power management integrated circuits, or PMICs, are devices that integrate the control, voltage regulation, monitoring and other components of a system into a single integrated circuit. A PMIC intended for use with field programmable gate arrays and other digital logic devices, commonly called a supervisors, typically consist of a Power-On-Reset (POR) circuit and a watchdog timer (WDT). The BU4210F-TR is one such supervisor which is manufactured by ROHM.The BU4210F-TR is a microprocessor-superior reset IC, intended to be used with field programmable gate arrays and other digital logic devices to protect the field programmable gate arrays and other digital logic devices from power-on failure or under-voltage conditions. It is a low power consumption device, suitable for various applications from consumer electronics to automotive systems.The BU4210F-TR has a wide operating voltage range of 1.8V to 5.5V and features an internal leak current of 0.7uA (typical). The reset output is active- LOW and has a fast response. The delay time for the reset output is typically 12mS. The reset output is a push-pull type and has a fast rise and fall time of 15ns and 20ns, respectively (typical).In addition to the power-on-reset and watchdog timer, the BU4210F-TR also includes additional features such as over-current protection and power-down reset. The integrated circutor is suitable for use in a broad range of applications, including automotive systems, consumer electronics, and computer peripherals.The power-on-reset is the main function of the BU4210F-TR. It prevents the CPU from executing operations during a power cycle that could be harmful to the device, and is usually enabled by the reset pin. The reset pin input is monitored by the power-on-reset circuit and will be held low until the voltage supplied to the device is greater than or equal to the reset threshold voltage established by the power-on-reset circuit. The output of the power-on-reset will then go high, allowing the CPU to begin operation.The watchdog timer is another important safety feature of the BU4210F-TR, as it can prevent a system from becoming hung up and unable to recover. The watchdog timer is used to detect abnormal system conditions such as when the system is stuck in a loop, or when an application is not responding in a timely manner. When the watchdog timer times out, the reset pin will be asserted, signaling the CPU to reset.The other safety feature of the BU4210F-TR is the over-current protection circuit. This circuit detects when a fault or over-current condition occurs and is designed to protect the system from damage in the case of an over-current event.The power-down reset function is used to reset the CPU and peripheral devices during power transfer from one power source to another. This feature is useful for applications such as when a battery is being replaced. It ensures that the device is functioning correctly and prevents any data corruption.In summary, the BU4210F-TR is a highly integrated power management IC that provides multiple safety features such as power-on-reset, watchdog timer, over-current protection and power-down reset. It is suitable for use in a wide range of applications, ranging from automotive systems to consumer electronics.
