(8) 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.
(9) When input current remains below 2 A, the battery charging current may be raised until the thermal regulation limits the charge current.
(10) For half-charge rate, V_(SET) is 1.25 V ± 25 mV for bq24032A/38 only.
(11) Specification is for monitoring charge current via the ISET1 pin during voltage regulation mode, not for a reduced fast-charge level.
(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) 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).
