(11) With the PSEL= low, the bqTINY III-series defaults to USB charging. If USB input is
≤
V
BAT
, then the bqTINY III-series charges from the
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
BAT
, then the bqTINY III-series charges from the
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.
