Hi team, I’m developing a portable system which needs a smart battery on it. The module I’m going to use is G400. I’m somehow concerned about the use of I2C to communicate the host to the battery.
The smart charger I’m using is the Linear LTC4100 with an Inpiredenergy Li-Ion battery ( ND2054HD29 ). Both devices communicate each other by using SMBus 1.1.
My concern is how to communicate the host to the bus. There shouldn’t be a problem to use the I2C bus ( by using also a I2C level driver since the bus signals are 3V3 and 5V ). Despite the timing issues I’m a little concerned about the multimaster capabilities. The battery behaves as a master to communicate to the charger but the host needs to behave as a master for communicating to the battery )
The LTC4100 datasheet states that the IC can be used to connect to a smart battery AND/or a host device to read status and battery info, but not completely sure about this.
Have anyone in the forum work with SMBus devices? I realized that netmf doesn’t have native support for SMBus.
Thanks and regards from Argentina.
