ADBMS2950 and ADBMS2952 are Battery Pack Monitors for electrical and hybrid vehicles, and other current or voltage sense applications. ADBMS2950 and ADBMS2952 measure the current flowing in and out of a battery pack by sensing the voltage drop over a shunt resistor with a very low offset.ADBMS2950 and ADBMS2952 also detect Overcurrent conditions using fast Overcurrent ADCs with digital threshold comparators and communicate their results through dedicated Overcurrent alert lines with minimum delay.ADBMS2950 and ADBMS2952 feature a total of 12 internally buffered high impedance inputs for measuring voltages from external sensors or resistor dividers, enabling measurement of pack voltages, temperatures, HV-Link voltages, chassis isolation, and the supervision of the state of contactors and fuses. Six digital outputs (GPO) supporting open-drain or push-pull can be used to control high voltage transistors to disconnect external resistor dividers. Four digital general-purpose inputs/outputs (GPIO) also allow operation as an I2C or SPI controller interface to address an external EEPROM or other serial peripherals.The built-in serial interface of ADBMS2950 can be configured for SPI or isolated isoSPI communication to the host. An additional isoSPI port allows to connect a daisy chain of ADBMS2950 devices; optionally extended with ADBMS6830 or ADBMS6832 (ADBMS683x) Cell Monitors. The ADBMS2952 supports SPI communication only.APPLICATIONS Electric and Hybrid Electric Vehicles Backup Battery Systems Grid Energy Storage
