目录产品概述 返回TOP CXLB74134 is a multi-cell battery stack monitoring and protection IC that includes a 12-bit ADC for battery voltage and temperature sense, a 12-bit ADC for charge/discharge current sense. CXLB74134 provides passive balance function for each cell and allows at most 3 consecutive cells being discharged simultaneously. CXLB74134has two ADC operation modes: fast mode and filtering mode. The fast mode enables conversion time as fast as 1280μs, while the filtering mode provides better than 80dB rejection at frequencies above 50Hz. CXLB74134communicates with external control unit via SPI interface. More CXLB74134can operate in series to monitor long string battery. CXLB74134integrates complete protection function including over/under voltage, over/under thermal, over charge/discharge current, short and open wire. CXLB74134supports both low-power mode and standby mode to achieve high efficiency with low power when charge/discharge current is minor.产品特点 返回TOP 8V≤Input voltage ≤60V operation，75V transient Monitor 14 series cell battery and support series operation 12-BIT ∆Σ ADC samples battery voltage and accuracy is 5V/212=1.22mV Provide filtering mode 4 channels thermal sense and accuracy is 5V/212=1.22mV Battery over/under voltage protection Battery over/under temperature protection Open wire connection detection 14 cells passive balance On-chip passive cell balancing switches Provide off-chip passive balancing 12-BIT ∆Σ ADC senses charge/discharge current and accuracy is 400mV/212=97μV Independent discharge control by the CTLD control pin Over Charge/Discharge current protection Charge/Discharge Short protection Reliable SPI communication (mode3) 3.3V and 5.0V LDO output for external application External protection N-MOSFETs Low power consumption During operation 1mA typ.
