The MAX8845Z/ MAX8845Y integrate a current-sense circuit, MOSFET pass element, thermal-regulation circuitry, and eliminates the external reverse-blocking Schottky diode to create the simplest and smallest charging solutions for handheld equipment. The ICs control the charging sequence from the prequalification state through constant current fast-charge, top-off charge, and full-charge indication. Proprietary thermal-regulation circuitry limits the d.
