Claimed as the world's smallest lithium-ion battery charger, the MAX1736 SOT-23 stand-alone charger for single-cell lithium-ion batteries features better than 0.5% battery-regulation voltage-accuracy and a complete state machine to safely control the charging sequence.
In conjunction with a current-limited wall cube, as external P-FET switch is used in a gated control scheme which does not generate heat like a linear-mode regulator. This allows the entire charging circuit to run very cool and fit in cellular/PCS phone handsets and low-power handheld equipment such as PDAs and portable digital-audio players. In a tiny 6-pin SOT-23 package, pricing for the device starts from $1.50 each/1,000.
