> Fast Charge Timer
> A programmable backup charge timer is available for fast
> charge termination. The timer is activated by the Time/Temp
> Select comparator, and is programmed from the t1/Tref High,
> t2/Tsen, and t3/Tref Low inputs. If one or more of these inputs
> is allowed to go above VCC – 0.7 V or is left open, the
> comparator output will switch high, indicating that the timer
> feature is desired. The three inputs allow one of seven
> possible fast charge time limits to be selected. The
> programmable time limits, rounded to the nearest whole
> minute, are shown in Figure 10.

> Over/Under Temperature Detection
> A backup over/under temperature detector is available
> and can be used in place of the timer for fast charge
> termination. The timer is disabled by the Time/Temp Select
> comparator when each of the three programming inputs are
> held below VCC – 0.7 V.
