DC1653A

DC1653A is a demo board for LTC6803-1 and -3 multicell battery stack monitor. It is a battery monitoring system to demonstrate the functional operation of the LTC6803-3 integrated circuit. The design includes the ability to daisy-chain up to 10 devices with built-in board-to-board ribbon-cable interconnects and selectively apply resistive loading to any cell for purposes of “Passive Balancing.” Additionally, the board includes an available DC-DC boost conversion section to power the IC from an isolated external 5V supply.

• Controllable discharging for passive balancing
• Enhanced protection circuitry for IC and external discharge transistors during hot plugging of cells
• GUI screen for demonstration of new features and program code development
• Available 60V boost supply from isolated 5V external supply
• Jumper configuration offers -5V offset for V- to support negative cell readings
• Footprint for LTC6655-3.3 calibration reference
