Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied.
(*) The I.C. is automatically turned OFF when VCHARGE reaches typically 14V (VCHARGE rising edge); typical hysteresis is 700mV (VCHARGE falling edge)


Description

This specification describes a dedicated I.C. which allows to charge 1 Lilon cell or 3 Nimh cells. The principle used to charge the batteries is the pulsed current, the monitoring is operated by the micro-contoller of the application. This IC integrates one Power Switch and achieves the charge batteries in two different modes charge or precharge.

One of this operating mode (charge or precharge) can be selected in a static or pulsed way by one I/O from a micro-controller. The IC can supply power to accessories controlled by this I.C. in Reverse mode. The I.C. is available in the smaller and surface mounted SO-8 (exposed pad version) package.
