Philips Semiconductors Objective specification
Cost effective battery monitor and fast
charge IC for NiCd and NiMH chargers
TEA1104; TEA1104T
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134); note 1.
Note
1. All voltages are measured with respect to ground; positive currents flow into the IC. The voltage ratings are valid
provided that other ratings are not violated; current ratings are valid provided that the power rating is not violated.
