9.2.3.5 Peripheral Features

9.2.3.5.1

LED Display

The BQ78350-R1A device is configured by default to display up to five LEDs in a bar graph configuration based

on the value of RemainingStateOfCharge() (RSOC). Each LED represents 20% of RSOC and is illuminated

when the BQ78350-R1A DISP pin transitions low, and remains on for a programmable period of time.

In addition to many other options, the number of LEDs used and the percentage at which they can be illuminated

are configurable.

9.2.3.5.2

SMBus Address

Although the SMBus slave address is a configurable value in the BQ78350-R1A device, this feature is disabled

by default and the slave address is 0x16. The SMBus Address feature can allow up to nine different addresses

based on external resistor value variation per address.

The default setup of the BQ78350-R1A device is generic, but there are many additional features that can be

enabled and configured to support a variety of system requirements. These are detailed in the BQ78350-R1A

Technical Reference Manual (SLUUBD3).

9.2.4 Application Performance Plots

When the BQ78350-R1A device is powered up, there are several signals that are enabled at the same time.

Figure 9 shows the rise time of each of the applicable signals.
