DESCRIPTION
Demonstration circuit 2515B features the
6-channel battery-stack monitor. Multiple boards can be
linked through a 2-wire isolated serial interface (isoSPI™)
to monitor a long series of cells in a stack. The DC2515B
demo board also features reversible isoSPI enabling a
redundant communication path. The PCB, components,
and DuraClik connectors are optimized for Low EMI
Susceptibility and Emissions.
The DC2515B can communicate to a PC by connecting
a DC2792B dual master isoSPI together with DC2026

One. The DC2026 must be loaded with the
®
appropriate program (called a sketch) to control the bat-
tery stack monitor IC and receive data through a USB
serial port. The DC2026C provides a standard SPI inter-
face which can be translated to isoSPI and then con-
nected to a DC2515B isoSPI port (J4 or J5 connector).
The DC2792B companion board provides two SPI-isoSPI
channels for reversible operation.

When connected to a battery-stack, power for the – C0/V DC2515B is provided by the cell group being monitored. To connect the cell group, separate the screw-terminal block section from the J1 connector. Then, insert the cell- voltage connections or resistors into the screw-terminal clamping contacts. - Page 3 PC with the Arduino IDE software is the first (or bottom) board of the stack. to allow communication to the DC2515B boards.
