BU46K262G-TL Application Field and Working PrinciplePMIC - Supervisors, specifically the BU46K262G-TL, provide high-level protection for electronic circuits. Systems incorporating the BU46K262G-TL use it to protect processor-based systems and systems other sensitive, high-value components from overvoltage and undervoltage conditions. In addition, they provide high-speed circuit protection, immunity to nuisance trips, low maximum operating current, and a low power mode to conserve power.The BU46K262G-TL is a three-terminal voltage supervisor manufactured by the semiconductor giant, ON Semiconductor. It is available in a variety of packages. The device features an input voltage range of ±12V, a low minimum supply voltage of 2V, and a maximum supply voltage of 6V. The device operates with a maximum operating current of 15uA. It also features an integrated power-on reset (POR) with a reset time of over-temperature protection.The BU46K262G-TL is very useful in applications such as power-supply sequencing and monitoring, embedded logic systems, automotive systems, transmission relays and SOICs, microprocessor systems, and PC, SBC, PLC, and HMI systems. The working principle of the BU46K262G-TL is fairly simple. A voltage supervisor monitors the supply voltage of a circuit and provides a signal when the supply voltage falls below or rises above certain threshold levels. When the voltage supervisor detects the supply voltage is outside the prescribed limits, it issues a signal to the system controller, instructing it to take appropriate corrective action. The corrective action may include disabling the power supply, engaging a battery backup system, or even engaging an emergency shutdown.When the supply voltage goes back within the acceptable range, the voltage supervisor will return to standby, waiting for the supply voltage to exceed the thresholds again. The BU46K262G-TL is designed with a window comparator with hysteresis in order to reduce the probability of nuisance trips. The device also features a low power mode that consumes less than 0.2uA. This allows system designers to conserve power while still ensuring battery-backed protection.In summary, the BU46K262G-TL is a three-terminal voltage supervisor manufactured by ON Semiconductor. It is used to protect processor-based systems, other sensitive, high-value components from overvoltage and undervoltage conditions. It features a low minimum supply voltage of 2V, and a maximum supply voltage of 6V. In addition, it features a low power mode to conserve power and a reset time of over-temperature protection. The BU46K262G-TL is useful in a wide range of applications and its working principle is simple.
