Using this charger, designers can quickly calibrate their GSM phones without having to install a battery. The MAX8922L is well suited for GSM, EDGE, UMTS, and CDMA cell phones.
The MAX8922L's input is overvoltage protected to 30V, eliminating the need for an external overvoltage-protection IC. The device includes a 4.94V LDO output to safely power the low-voltage Vbus input. The fast-charge current and top-off current thresholds can be configured using an external resistor for design flexibility. The MAX8922L also allows the fast-charge current and GSM test mode to be programmed through a single-wire interface. The charger status and valid input power are indicated by two open-drain outputs.
The MAX8922L is packaged in a 3mm x 2mm, 10-pin TDFN.
