Product Description

The BQ2002TSN is a fast-charge Integrated Circuit features CMOS battery-charge controller able to provide reliable charge termination for both NiCd and NiMH battery applications. Controlling a current-limited or constant-current supply allows the IC to be the basis for a cost-effective stand-alone or system-integrated charger. The BQ2002T integrates fast charge with optional top-off and pulsed-trickle control in a single IC for charging one or more NiCd or NiMH battery cells. Fast charge is initiated on application of the charging supply or battery replacement. For safety, fast charge is inhibited if the battery temperature and voltage are outside configured limits. After fast charge, the IC optionally tops-off and pulse-trickles the battery per the pre-configured limits. Fast charge may be inhibited using the INH pin. The IC may be placed in low-standby-power mode to reduce system power consumption.
