Maxim 71M6521BE-IGT/F, LQFP-64 package, Power Management Monitoring IC

The Maxim 71M6521BE-IGT/F is a Power Management Monitoring IC. The 71M6521BE is a highly integrated SoC with an MPU core, flash, and LCD driver. Teridians Single Converter Technology® with a 22-bit, delta-sigma ADC; four analog inputs; digital temperature compensation; precision voltage reference; battery voltage monitor; and 32-bit computation engine (CE) supports a wide range of residential metering applications with very few low-cost external components. A 32kHz crystal time-base for the entire system further reduces system cost. The IC supports 2-wire single-phase residential metering along with tamper-detection mechanisms.
