RTKA489204DE0000BU

RTKA489204DE0000BU is an evaluation board that facilitates testing of the RAA489204 Li-ion battery pack analogue front-end ICs. The RAA489204 monitors cell voltage and temperature, and provides 14bit digital values, cell balance control, and significant fault detection. The RAA489204 also contains daisy chain hardware to provide robust board-to-board communication. Daisy chain capacitive coupled (direct board-to board or cable connected) or transformer coupled cable connected (capacitor or transformer selected by jumper). GUI provided export option for generation of detailed register, voltage, and/or SPI communications log files.

• Supports both stand-alone and daisy chained configurations
• External cell balance operation
• Cell voltages monitored after balance resistor to meet safety fault detection goals
• USB microcontroller dongle runs HID firmware for enumeration and communications with Windows
• VBAT voltage range from 12V to 65V
• Cell voltage -5V to +5V (note: no cell voltage can go below pack ground or above 65V)
• Two GPIO ports to monitor temperature (default) or general-purpose input or output
• External inputs ExT1 to ExT4 = 0V to 2.5V (external temperature measurement thermistors on board)
