(10) With the PSEL= low,the bqTINY-III defaults to USB charging. If USB input is grounded, then thebqTINY-III charges from the AC input at
the USB charge rate. In thisconfiguration the specification is 75 mA (min) and 95 mA (max).
(11) With the PSEL= low,the bqTINY-III defaults to USB charging. If USB input is grounded, then thebqTINY-III charges from the AC input at
the USB charge rate. In thisconfiguration the specification is 375 mA (min) and 475 mA (max).
(12) All deglitch periodsare a function of the timer setting.
