max8922l 30v li+电池线性充电器，提供gsm测试模式
概述
the max8922l linear battery charger safely charges a single-cell lithium-ion (li+) battery. charging rate is optimized to accommodate the thermal characteristics of a given application. there is no need to reduce the maximum charge current at the worst-case charger power dissipation. charging is optimized for a single li+ cell using a control algorithm that includes low-battery precharging, voltage and current-limited fast charging, and top-off charging, while continuously monitoring for input overvoltage and device die-temperature conditions. the fast-charge current and top-off current thresholds are programmable by a simple 1-wire® serial interface. the charger status and valid input power are indicated by two open-drain outputs (active-low chg and active-low pok).
the fast-charge current is defaulted to 400ma and programmable through the 1-wire interface (active-low en/set). the max8922l also can be programmable to gsm test mode through the 1-wire interface.
the max8922l is available in a tiny (3mm x 2mm x 0.8mm) 10-pin tdfn package.
