PRODUCTION DATA
The VINDPM loop prevents the input voltage from collapsing to a point where charging would be interrupted by reducing the current drawn by charger in order to keep VIN from dropping below VIN_DPM. Once the IN voltage drops to VIN_DPM, the VINDPM loops will reduce the input current through the blocking FETs, to prevent the further drop of the supply voltage. The VINDPM function is enabled by default and may be disabled through I2C command. The VIN_DPM threshold is programmable through the I2C register from 4.2 V to 4.9 V in 100-mV steps.
DPPM is disabled by default in this device and cannot be re-enabled through I2C. When the device enters this mode, the charge current may be lower than the set value and the corresponding status bits and flags are set. If the 2X timer is set, the safety timer is extended while the loop is active. Additionally, termination is disabled.
