Fairchild Semi Develops FAN7563 and FAN7564, Battery-Charging ICs

December 13, 2000 by Jeff Shepard

Fairchild Semiconductor (San Jose, CA) introduced two battery-charging controller ICs, the FAN7563 and FAN7564, that provide constant current and constant voltage charging of lithium-ion batteries used in handheld applications.

The FAN7563 and FAN7564 operate from 2.5 to 16V and provide end-of-charge current control. The FAN7564 implements an LDO control function and delivers driving output that can be used with an external transistor to provide a regulated supply for a microcontroller.

Both devices' charging profiles are tailored for lithium-ion batteries. The FAN7563 supports travel charger designs and the FAN7564 supports both travel and desktop chargers. Integrated charging functions include end-of-charge dv/dt detection and reduced-current trickle charge.

The FAN7563 is available in 8-lead SOP packages for $0.88 each, in quantities of 1,000 pieces. The FAN7564 is available in 14-lead SOP packages for $0.98 each, in quantities of 1,000.
