产品说明

The EMB1432Q Battery Stack Module Analog Front End is a high voltage analog interface designed to monitor a lithium battery stack. It is able to select and level shift the voltage across any of 14 stacked batteries and 2 low voltage auxiliary inputs, multiplexing the signals to an output pin. The multiplexer output is set by writing to an internal register using the SPI™ protocol or by directly addressing 4 digital pins. The voltage across each battery can range from –2 V to 5.5 V without damaging the AFE, with the top cell positive pin reaching 60 V. The SENSE(N) input impedance (when the Nth battery is selected) is 1 MΩ typ, and the current drawn from SENSE(N-1) is 2 µA typ. When not selected or in shutdown mode, the current at any sense input drops to less than 1 µA.

The EMB1432Q can precisely level shift a battery voltage ranging from 0.5 V to 4.6 V with a gain of 1, an input referred offset voltage of ±1 mV and a gain error of 0.05% (max). The EMB1432Q operates with 5 V and –5 V supplies. Single supply operation is also supported: the –5 V supply can be internally generated using an internal charge pump. The I/O communication interface can be supplied through dedicated supply pins (VIO, DGND). The EMB1432Q is designed to provide accurate analog output over the AEC-Q100 type 2 temperature range of –40°C to 105°C and to be able to operate up to 125°C.
