ANALOG DEVICES VT1697SBFQX Smart IC, Integrated Current, Temperature Sensor, 1.71 V to 1.98 V, FCQFN-16, -40 °C to 125 °C

VT1697SB is a feature-rich smart server IC designed to work with Analog Devices seventh-generation hosts to implement a high-density multiphase voltage regulator. Up to six smart server ICs plus a host IC provide a compact synchronous buck converter that includes accurate individual phase current and temperature reporting through SMBus. This smart-server device includes protection circuits for overtemperature, VX short, all power supplies UVLO faults, and main power supply OVLO fault. If a fault is detected, the server IC immediately shuts down and sends a fault signal to the host IC. Monolithic integration and advanced packaging technologies allow practical per-phase high switching frequencies with significantly lower losses than alternative implementations. Application includes high-current voltage regulators, microprocessor 32bit and 64-Bit I/A RISC architectures, memory, graphic processors, networking ASICs.
