When powered by a battery, the IP5306 restarts when the SIM 800 DC-DC power is turned on. According to my observations with the help of an analyzer and an oscilloscope, the reset occurs from overcurrent at the time of powering up the sim800 module. Communication with ip5306 via i2c works fine, registers are polled. I use a li-po battery, there are no voltage dips on it. Help please.
