MAX15492Single-Phase Synchronous MOSFET Driver with Ultra-Low-Power Mode | Unclassified | 4 | Unknown | The MAX15492 is a synchronous half-bridge driver with ultra-low-power mode. The device is intended to work with controller ICs such as the MAX15411, MAX15566/MAX15567, or MAX15576/MAX15577 in multiphase CPU core regulators. To provide the best light-load efficiency, the controller can place the device into an ultra-low power mode where the supply current is only 4µA.The low-side driver is optimized to drive 3nF capacitive loads with 3ns/7ns typical fall/rise times, and the high-side driver with 7ns/14ns typical fall/rise times. Adaptive dead-time control prevents shoot-through currents and maximizes converter efficiency.The MAX15492 is available in a small, 8-pin (2mm × 2mm) TDFN package with an exposed pad.ApplicationsIntel® Ultrabook™/Notebook ComputersMultiphase DC-DC ConvertersTablet Computers |
MAX155High-Speed, 8-Channel, 8-Bit ADC with Simultaneous Track/Holds and Reference | ADCs/DACs - Special Purpose | 11 | Active | The MAX155/MAX156 are high-speed, 8-bit, multichannel analog-to-digital converters (ADCs) with simultaneous track/holds (T/Hs) to eliminate timing differences between input channel samples. The MAX155 has 8 analog input channels and the MAX156 has 4 analog input channels. Each channel has its own T/H, and all T/Hs sample at the same instant. The ADC converts a channel in 3.6µs and stores the result in an internal 8x8 RAM. The MAX155/MAX156 also feature a 2.5V internal reference and power-down capability, providing a complete, sampling data-acquisition system.When operating from a single +5V supply, the MAX155/MAX156 perform either unipolar or bipolar, single-ended or differential conversions. For applications requiring wider dynamic range or bipolar conversions around ground, the VSSsupply pin may be connected to -5V.Conversions are initiated with a pulse to the active-low WR pin, and data is accessed from the ADC’s RAM with a pulse to the active-low RD pin. A bidirectional interface updates the channel configuration and provides output data. The ADC may also be wired for output-only operation.The MAX155 comes in 28-pin PDIP and wide SO packages, and the MAX156 comes in 24-pin narrow PDIP and 28-pin wide SO packages.ApplicationsAC Power MetersDSP Analog InputPhase-Sensitive Data AcquisitionPortable Data LoggersVibration and Waveform Analysis |
MAX15500Industrial Analog Current/Voltage Output Conditioners | ADCs/DACs - Special Purpose | 2 | Active | The MAX15500/MAX15501 analog output conditioners provide a programmable current up to ±24mA, or a voltage up to ±12V proportional to a control voltage signal. The control voltage is typically supplied by an external DAC with an output voltage range of 0 to 4.096V for the MAX15500 and 0 to 2.5V for the MAX15501. The output current and voltage are selectable as either unipolar or bipolar. In the unipolar configuration, a control voltage of 5% full-scale (FS) produces a nominal output of 0A or 0V to achieve underrange capability. A control voltage of 100%FS produces one of two programmable levels (105%FS or 120%FS) to achieve overrange capability. The outputs of the MAX15500/MAX15501 are protected against overcurrent conditions and a short to ground or supply voltages up to ±35V. The devices also monitor for overtemperature and supply brownout conditions. The supply brownout threshold is programmable.The MAX15500/MAX15501 are programmed through an SPI™ interface capable of daisy-chained operation. The MAX15500/MAX15501 provide extensive error reporting through the SPI interface and an additional open-drain interrupt output. The devices include an analog output to monitor load conditions.The MAX15500/MAX15501 operate over the -40°C to +105°C temperature range. The devices are available in a 32-pin, 5mm x 5mm TQFN package.ApplicationsDistributed I/OsEmbedded SystemsIndustrial Control and AutomationProgrammable Logic Controllers (PLCs) |

MAX1551SOT23, Dual-Input, USB/AC Adapter, 1-Cell Li+ Battery Chargers | Battery Chargers | 1 | Active | The MAX1551 and MAX1555 charge a single-cell lithium-ion (Li+) battery from both USB and AC adapter sources. They operate with no external FETs or diodes, and accept operating input voltages up to 7V.On-chip thermal limiting simplifies PC board layout and allows optimum charging rate without the thermal limits imposed by worst-case battery and input voltage. When the MAX1551 and MAX1555 thermal limits are reached, the chargers do not shut down, but progressively reduce charging current.The MAX1551 includes an active-low POK output to indicate when input power is present. If either charging source is active, active-low POK goes low. The MAX1555 instead features a active-low CHG output to indicate charging status.With USB connected, but without DC power, charge current is set to 100mA (max). This allows charging from both powered and unpowered USB hubs with no port communication required. When DC power is connected, charging current is set at 280mA (typ). No input-blocking diodes are required to prevent battery drain.The MAX1551 and MAX1555 are available in 5-pin thin SOT23 packages and operate over a -40°C to +85°C range.ApplicationsCell PhonesDigital CamerasPDAsWireless Appliances |
