(11) With the PSEL= low, the bqTINY III-series defaults to USB charging. If USB input is

≤ V

AC input at the USB charge rate. In this configuration, the specification is 400 mA (min) and 500 mA (max).

(12) With the PSEL= low, the bqTINY III-series defaults to USB charging. If USB input is

≤ V

AC input at the USB charge rate. In this configuration, the specification is 80 mA (min) and 100 mA (max).

(13) 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.
