(12) With the PSEL= low, the bqTINY-III defaults to USB charging. If USB input is ≤ VBAT, then the bqTINY-III charges from the AC input at
the USB charge rate. In this configuration, the specification is 400 mA (min) and 500 mA (max) for bq24030/2/2A/5/8 only.
(13) With the PSEL= low, the bqTINY-III defaults to USB charging. If USB input is ≤ VBAT, then the bqTINY-III charges from the AC input at
the USB charge rate. In this configuration, the specification is 80 mA (min) and 100 mA (max) for bq24030/1/2A/5/8 only; 75 mA (min)
and 100 mA (max) for bq24032.
(14) ISET3 - bq24039 only; ISET3 = High-increases current range by a factor of 2 (min - max)
(15) All deglitch periods are a function of the timer setting and is modified in DPPM or thermal regulation modes by the percentages that the
program current is reduced.
