Other Parts Discussed in Thread: BQ25720
Hi Dear,
Our customer uses BQ25720 and has two problems.
1.Because the number of MCU IO ports is insufficient, check whether the three wires BAT_GD & BAT_LOW& BI/TOUT can not be connected to MCU, and send the I2C command to obtain the battery status information?
2. When VREGIN is equal to 3.6V, the LDO output range is 2.3-2.6V,as follows.
If the LDO output is 2.3V, the VOH can reach the maximum of 2.3V. But the MCU can recognize the high level VIH=2.31V. which may cause problems in the communication between the BQ25720 and MCU?which may lead to problems in communication between.
