The ADP5585 is a 10I/O port expander with built-in keypad matrix decoder, programmable logic, reset generator, and PWM generator. I/O expander ICs are used in portable devices (phones, remote controls, & cameras) and non-portable applications (healthcare, industrial & instrumentation). I/O expanders can be used to increase the number of I/Os available to a processor or to reduce the number of I/Os required through interface connectors for front panel designs.The ADP5585 handles all key scanning and decoding and can flag the main processor via an interrupt line that new key events have occurred. GPI changes and logic changes can also be tracked as events via the FIFO, eliminating the need to monitor different registers for event changes. The ADP5585 is equipped with a FIFO to store up to 16 events. Events can be read back by the processor via an I2C compatible interface.The ADP5585 frees up the main processor from having to monitor the keypad, thereby reducing power consumption and/or increasing processor bandwidth for performing other functions.The programmable logic functions allow common logic requirements to be integrated as part of the GPIO expander, saving board area and cost.APPLICATIONS Keypad entries and input/output expansion capabilities Smart phones, remote controls, and cameras Healthcare, industrial, and instrumentation

The ADP5600 is an interleaved charge pump inverter with an integrated, negative, low dropout (LDO) linear regulator. The interleaved charge pump inverter exhibits reduced output voltage ripple and reflected input current noise over conventional inductive or conventional capacitive based solutions. The integrated LDO provides a rail with good regulation at sufficient power supply rejection ratio (PSRR).The ADP5600 charge pump operates via resistor programming or external clock synchronization at switching frequency range of 100 kHz to 1 MHz.

To combine the high switching frequency with internal field effect transistors (FETs), compensation, and soft start gives a best-in-class total solution size for negative rail generation.The ADP5600 also features comprehensive fault protection for robust applications. These protections include overload protection, shorted fly capacitor protection, undervoltage lockout (UVLO), and thermal shutdown. For easy sequencing, the ADP5600 has a power-good pin.The integrated LDO of the ADP5600 uses an advanced proprie-tary architecture to provide high power supply rejection. It also achieves decent line and load transient response with only a small 2.2 ?F ceramic output capacitor. The output can be configured via the SEL1 and SEL2 pins to one of four fixed output voltages and is adjustable from ?0.505 V to ?VIN + 0.5 V via an external feedback divider.APPLICATIONSPowering the negative rail on bipolar/split supply ADC/DAC/AMP/mux applications
