DA9155M
2.5 A Companion Charger for rapid charging
The junction temperature monitoring is also enabled in the reset mode. If a junction over-temperature
is detected during operation (TJUNC ≥ TJUNC_POR), DA9155M moves back to the reset mode.
10.8.3 Disabled
In the disabled mode DA9155M is fully functional but the Buck has not been enabled. An event is
fired when entering the disabled mode to notify the application processor that the slave charger is
ready for operation. If a fault condition exists (T_JUNC, V_BAT, or V_IN), the enable signal is blocked,
DA9155M stays in the disabled mode, and an event is triggered.
DA9155M moves to the active mode when the Buck is enabled either by asserting the EN signal or
by setting the BUCK_EN register.
10.8.4 Active
In the active mode DA9155M is fully functional and the Buck is running.
DA9155M moves back to the disabled mode if the Buck is disabled, the safety timer expires, or if
there is a fault condition (T_JUNC, V_BAT, or V_IN).
