Cost effective battery monitor and fast
charge IC for NiCd and NiMH chargers
TEA1104; TEA1104T
Output drivers
Several output drive possibilities are supported by the
TEA1104, to limit the fast charge current and to indicate
the mode that the charge is in.
In mains isolated systems, output drive current is available
for a bipolar or MOS switching device. Moreover, current
regulators can be driven (see Fig.4).
In non mains isolated systems, the current source can be
switched via the auxiliary winding (see Fig.6) using the
TEA140X power plugs.
In the application section, an example is shown driving two
LEDs that are indicating fast charging, protection during
fast charging, full status and removed batteries. It is also
possible to output the same information via one LED only.
