Infineon's IPS521 power management IC is a highly integrated, low-cost solution for system power gating and sequencing. It combines logic and power MOSFETs to provide up to 4 power gating and sequencing functions in a 4x4 BGA package, saving valuable board space with a sleeker and more compact design. The IPS521 is designed to consolidate power rails in a wide variety of portable and embedded applications such as signal conditioning, analog circuitry, digital and high-speed circuits, power converters, wireless communication, etc. It also features an adjustable Hi-Z impedance, which improves system compatibility and accuracy. With integrated logic and an adjustable current-limit protection mechanism, the IPS521 is fully integrated at the transistor level, eliminating the need for discrete components and reducing BOM size and cost. Additionally, the device supports factory programming of several parameters, such as delay times, for custom power-management solutions.
