Power management integrated circuits (PMICs) have become more and more essential in both traditional and modern electronic designs. PMICs provide precise power regulation, efficient power conversion, and reliable power control to electrical systems in order to ensure steady, uninterrupted power and data availability. Among all kinds of PMICs, supervisors are important components that detect and monitor power supply glitches, low voltage, side currents, etc., and provide necessary protection to the design. The LTC2966IUD#PBF PMIC supervisor is a highly integrated supervisor and auxiliary power source solution for monitoring and protection of DC sources and system supplies in a wide range of applications. The LTC2966IUD#PBF can be used to monitor any type of current, voltage, or mixed-signal power supply. This supervisor also features an integrated adjustable voltage regulator, allowing the user to choose the ideal voltage for their design.Applications of LTC2966IUD#PBFThe LTC2966IUD#PBF has many applications in digital power supplies, IP networks, and telecommunications systems. Furthermore, this PMIC supervisor provides reliable protection and monitoring in automotive electronics, embedded systems, and distributed power architectures. Working Principle of LTC2966IUD#PBFThe LTC2966IUD#PBF provides protection against power glitches, low power, input overvoltage, and over/under-current. The highly integrated solution protects both the primary and auxiliary supplies, and includes an adjustable voltage regulator, enabling the user to tailor the output voltage to their exact requirements.The LTC2966IUD#PBF contains two independent regulators that are used to monitor and control voltage and current levels. The adjustable voltage regulator monitors the output voltage from the main supply (VDD), and the current limit regulator monitors the current delivered to the load. Both regulators are adjustable and can be programmed for pre-defined voltage and current levels.The adjustable voltage regulator (AVR) monitors the main VDD supply and sets the output voltage for the desired level. The adjustable current limit (ACL) monitors the current consumed by the load and triggers the AVR if the current draws more than the predetermined level. This feature helps prevent damage to the system from current overloads.The AVR and ACL feature an integrated watchdog timer (WDT) to detect fault conditions and take the necessary corrective action. The WDT monitors the supply voltage, current, and other conditions and generates an alert signal If any of these parameters exceed preset thresholds. The alert signal is then used to reset the supply to the safe levels.ConclusionThe LTC2966IUD#PBF PMIC supervisor provides multiple protection functions against faults, low power, input overvoltage, and over/under-current conditions. Its integrated adjustable voltage regulator allows users to customize the output voltage to their exact needs, while its adjustable current limit helps protect the system from current overloads. With the integrated watchdog timer, the LTC2966IUD#PBF enables reliable, cost-effective protection and monitoring of the main supply in a wide range of applications. Therefore, it is an ideal solution for any design that is looking for reliable power monitoring and protection.
