The device has a battery detect scheme that allows it to automatically detect the presence and absence of a battery. When the battery is detected, charging begins in one of three phases (depending upon battery voltage): precharge, constant current (fast-charge current regulation), and constant voltage (fast-charge voltage regulation). The device will terminate charging when the termination current threshold has been reached and will begin a recharge cycle when the battery voltage has dropped below the recharge threshold (VRCG). Precharge, constant current, and termination current can be configured through the ISET1 and ISET2 pins, allowing for flexibility in battery charging profile. During charging, the integrated fault monitors of the device, such as battery short detection (VSHORT), thermal shutdown (internal TSHTDWN and TS pin), and safety timer expiration (TTC pin), ensure battery safety. bqSWITCHER™ has three status pins (STAT1, STAT2, and PG) to indicate the charging status and input voltage (AC adapter) status. These pins can be used to drive LEDs or communicate with a host processor. Figure 3.
