The MAX14525ETA features a low RON 35mΩ (typ) load switch with four unique enable inputs. The MAX14525ETA is ideal for disconnecting the lithium-ion (Li+) battery from the loads in portable devices such as cell phones. The MAX14525ETA operates from a +2.2V to +5.5V supply voltage. The MAX14525ETA features an extremely low 0.8μA (typ) quiescent supply current to maximize battery life in portable devices. It is enabled from four possible inputs: external charger connection capable of high voltage up to +28V, travel adapter (TA), on key (ON_K), factory mode enable (JIG), and switch enable (S_EN). The S_EN input is internally ANDed with the switched battery connection (IN). The MAX14525ETA is available in a small 8-pin, 2mm x 2mm TDFN package and operates over the -40°C to +85°C extended temperature range.
