PS3180

Preliminary PS3180 SmartShuntTM Battery Monitor Performs all major battery monitoring and reporting functions including: String voltage measurement, Precise current measurement and integration, Accurate capacity monitoring and integration with precise on-board timebase, Temperature measurement in 0.1°C intervals. www.DataSheet4U.com Industry’s highest accuracy battery monitor based on the PS331 Smart Battery IC: On-chip 14-bit integrating A/D converter, On-chip 8-bit RISC microprocessor, PowerSmart patented, self-learning algorithms and 3-dimensional battery cell models. Advanced communications interface using industry standard SMBus V1.1 with PEC/CRC-8 error correction. Extremely low power operation: Sleep Mode: <12 µA typical Sample Mode: <250 µA typical Run Mode: <500 µA typical FEATURES GENERAL DESCRIPTION The PS3180 SmartShunt™ is a completely selfcontained advanced battery monitoring and reporting device. The SmartShunt™ is a high current, integrated shunt/sense resistor assembly. The module includes PowerSmart’s Smart Battery IC and additional circuitry mounted on a high current shunt for simple system integration. The complete module can replace a normal bus-bar or battery cell interconnect. External connections include a communications interface (SMBus) which can be easily isolated, an optional external temperature sensor, and a string voltage input. The PS3180 SmartShunt™ can be used as a “nonintelligent sensor” where only current, in...
