8.3.20 Charge Status Outputs

The open-drain STAT1 and STAT2 outputs indicate various charger operations as listed in Table 2. These status pins can be used to drive LEDs or communicate with the host processor.

NOTE

OFF indicates that the open-drain transistor is turned off.

Table 2. STAT Pin Definition for BQ24650

CHARGE STATE STAT1 STAT2
Charge in progress ON OFF
Charge complete OFF ON
Charge suspend, overvoltage, sleep mode, battery absent OFF OFF
