The MAX7310 provides 8-bit parallel input/output port expansion for SMBus™-compatible and I²C-compatible applications. The MAX7310 consists of an input port register, an output port register, a polarity inversion register, a configuration register, a bus timeout register, and an SMBus/I²C-compatible serial interface. The system master can invert the MAX7310 input data by writing to the active-high polarity inversion register. The system master can enable or disable bus timeout by writing to the bus timeout register.Any of the eight I/O ports can be configured as input or output. An active-low reset input sets the eight I/Os as inputs. Three address-select pins configure one of 56 slave ID addresses.The MAX7310 is available in 16-pin thin QFN, TSSOP, and QSOP packages and is specified over the -40°C to +125°C automotive temperature range.ApplicationsCellular HandsetsDesktop Computers: MotherboardsGPIOIndustrial ControlIndustrial DisplaysInstrumentation and Test MeasurementMedical EquipmentRAID SystemsServersWhite LED Drivers

The MAX7314 I²C-compatible serial interfaced peripheral provides microprocessors with 16 I/O ports plus one output-only port and one input-only port. Each I/O port can be individually configured as either an open-draincurrent-sinking output rated at 50mA and 5.5V, or a logic input with transition detection. The output-only port can be assigned as an interrupt output for transition detection. The outputs are capable of driving LEDs, or providinglogic outputs with external resistive pullup up to 5.5V.Eight-bit PWM current control is built in for all 17 output ports. A 4-bit global control applies to all LED outputs and provides coarse adjustment of current from fully off to fully on with 14 intensity steps in between. Each output has an individual 4-bit control, which further divides the globally set current into 16 more steps. Alternatively, the current control can be configured as a single 8-bit control that sets all outputs at once.Each output has independent blink timing with two blink phases. All LEDs can be individually set to be on or off during either blink phase, or to ignore the blink control. The blink period is controlled by a clock input (up to 1kHz)on BLINK or by a register. The BLINK input can also be used as a logic control to turn the LEDs on and off, or as a general-purpose input.The MAX7314 supports hot insertion. All port pins, the active-low INT output, SDA, SCL, active-low RST, BLINK, and the slave address input ADO remain high impedance in powerdown (V+ = 0V) with up to 6V asserted upon them. The MAX7314 is controlled through a 2-wire serial interface, and uses four-level logic to allow four I²C addresses from only one select pin.ApplicationsKeypad BacklightsLCD BacklightsLED Status IndicationRelay DriversRGB LED DriversSystem I/O Ports

The MAX7315 I²C-/SMBus™-compatible serial interfaced peripheral provides microprocessors with 8 I/O ports. Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA at 5.5V, or a logic input with transition detection. A ninth port can be used for transition detection interrupt or as a general-purpose output. The outputs are capable of directly driving LEDs, or providing logic outputs with external resistive pullup up to 5.5V.PWM current drive is integrated with 8 bits of control. Four bits are global control and apply to all LED outputs to provide coarse adjustment of current from fully off to fully on in 14 intensity steps. Each output then has individual 4-bit control, which further divides the globally set current into 16 more steps. Alternatively, the current control can be configured as a single 8-bit control that sets all outputs at once.The MAX7315 is pin and software compatible with the PCA9534 and PCA9554(A).Each output has independent blink timing with two blink phases. All LEDs can be individually set to be on or off during either blink phase, or to ignore the blink control. The blink period is controlled by a register.The MAX7315 supports hot insertion. All port pins, the active-low INT output, SDA, SCL, and the slave address inputs AD0-2 remain high impedance in power-down (V+ = 0V) with up to 6V asserted upon them.The MAX7315 is controlled through the 2-wire I²C/SMBus serial interface, and can be configured to one of 64 I²C addresses.ApplicationsCell PhonesKeypad BacklightsLaptop ComputersLCD BacklightsLED Status IndicationPortable EquipmentRGB LED Drivers

The MAX8552 highly integrated monolithic MOSFET driver can drive a pair of power MOSFETs in single or multiphase synchronous buck-converter applications that provide up to 30A output current per phase. The MAX8552 simplifies PC board layout in multiphase systems, particularly three phases and higher. High input voltages up to 24V allow the MAX8552 to be used in desktop, notebook, and server applications. Each MOSFET driver can drive 3000pF capacitive loads with only 12ns propagation delay and 11ns (typ) rise and fall times, making the MAX8552 ideal for high-frequency applications.User-programmable break-before-make circuitry prevents shoot-through currents, maximizing converter efficiency. An enable input allows total driver shutdown (The MAX8552 is available in space-saving 10-pin TDFN and µMAX packages and is specified for -40°C to +85°C operation.ApplicationsDesktops, Notebooks, and ServersMultiphase Buck ConvertersProcessor-Core Voltage RegulatorsSwitching Power SuppliesVoltage Regulator Modules (VRMs)
