The SA61930B is a battery backup system management IC. It includes a 500mA linear regulator and a 100mA linear charger which can support 2-cell Ni-MH batteries. The low-quiescent current and low-dropout voltage minimize heat dissipation. The regulator has over-load and short-circuit protection. The charger has charge state indication before and during charging and cell-temperature monitor.
