Power Management ICs (PMICs) are integrated circuits (ICs) used in electronic devices to directly manage the power supplies. The core responsibilities include power sequencing, system monitoring and voltage regulation tasks, as well as enabling the external power sources and raising the system ready signals to start the system. PMICs are usually integrated with microcontrollers and related peripheral devices. One type of PMICs is called supervisor ICs or voltage supervisory ICs, which are used to monitor power supplies, supervise system reset and restart, and provide power-on reset (POR), also known as power-on reset control. Voltage supervisory ICs are designed to sense power-up/down conditions and generate a warning before the power switch starts operating. In addition, the ICs can detect the sudden changes of power input for various applications, and adjust the reference voltage voltage of the system. The BU46K274G-TL voltage supervisor is a low power-consumption CMOS supervisory circuit that resembles a small microcontroller. This compact device comes with built-in watchdog timer and its high accuracy power-on reset control supports a wide voltage range from 1.8 V to 5.5 V. This IC also provides stable operation in various temperature range, high noise immunity and reliable protection against power supply transients. The BU46K274G-TL can be used in many applications such as monitoring critical system power supplies, system reset and restart, and protecting circuits from sudden power supply changes. This integrated circuit works with an external capacitor connected to the delay port in order to create an initial delay at power-on-reset (POR), to ensure the power supply can stabilize before the start of operations. Once the delay has been completed, the IC will pull the reset output pin low, signaling the microcontroller that the power is stable and ready for operations. In addition, the BU46K274G-TL can be used to sense the power supply, monitor system status and/or 3V, 1.8V and DDR power supplies, reset the system, and protect the microcontroller from power supply transients. The IC includes a comparator, reference voltage, and a reset sync circuit, which serves as a watchdog timer. When the external voltage dips below the reference voltage, the comparator will trigger an output, which resets the microcontroller. The reset synchronization circuit prevents excessive resetting, reducing the reset time and allowing the system to continue operations until the power supply is back to normal. The IC also has a watch-dog timer that can be used to actually time-out system operations if necessary. This timer prevents runaway code, and issues reset signals when system performance falls out of acceptable limits. In summary, the BU46K274G-TL voltage supervisor is a low power-consumption CMOS supervisory circuit designed for applications such as power supply monitoring, system reset, system restart, and protection against power supply transients. The integrated circuit comprises a comparator, reference voltage, watch-dog timer and reset synchronization circuit, which together provide a one-stop solution for protecting different types of electrical circuits from power supply transients and other unexpected events.
