UART Interface

The battery-management UART protocol allows up to

32 devices to be connected in daisy-chain fashion (see

Figure 28). The host initiates all communication with the

daisy-chain devices through a UART interface such as

the MAX17841B. The data flow is always unidirectional

from the host, up the daisy-chain (upstack) and then loops

back down the daisy-chain (downstack) to the host.

Each device first receives data at its lower RX port and

immediately retransmits data from its upper TX port to the

lower RX port of the next upstack device. The last device

transmits data from its upper TX port directly into its upper

RX port and then immediately retransmits the data from

its lower TX port to the upper RX port of the next down-

stack device. The protocol supports fixed baud rates of

2Mb/s, 1Mb/s, or 0.5Mb/s. The baud rate is set by the host

and is automatically detected by the device.
