19-1655; Rev 2; 5/10 EVALUAATVIOANILKAIBTLMEANUAL CDMA Cellular/PCS System Power Supplies MAX1798/MAX1798A/MAX1799/MAX1799A General Description The MAX1798/MAX1798A/MAX1799/MAX1799A system power supplies are designed specifically for CDMA cellular/PCS handsets. Each device contains five lowdropout linear regulators (LDOs), a 140ms (min) reset timer, a serial interface, push-on/push-off control logic, and two general-purpose open-drain outputs. Only the serial interface is different between the MAX1798/ MAX1798A/MAX1799/MAX1799A: the MAX1798/ MAX1798A feature an SPI™-compatible serial interface, and the MAX1799/MAX1799A feature an I2C-compatible interface. The “A” parts have a -13% reset threshold, the non-A parts have a 9.5% threshold.
