The MAX17595 offers optimized input rising and falling thresholds for universal input AC-DC converters and telecom DC-DC (36Vâ€“72V input range) power supplies. The MAX17596 offers input rising and falling thresholds suitable for low-voltage DC-DC applications (4.5Vâ€“36V input range). The MAX17597 offers all circuitry needed to implement a boost converter controller. All three controllers contain a built-in gate driver for external n-channel MOSFETs. The MAX17595/MAX17596/MAX17597 house an internal error amplifier with 1% accurate reference, useful in implementations without the need for an external reference. The switching frequency is programmable from 100kHz to 1MHz with an accuracy of 8% using an external resistor, allowing optimization of magnetic and filter components, resulting in compact and cost-effective power conversion solutions. For EMI sensitive applications, the MAX17595/MAX17596/MAX17597 family incorporates a programmable-frequency dithering scheme, enabling low-EMI spread-spectrum operation.

The OVI pin enables implementation of an input overvoltage protection scheme, ensuring that the converter shuts down when the DC input voltage exceeds a set maximum value. The SS pin allows programmable soft-start time for the power converter, and helps limit inrush current during startup. The MAX17595/MAX17596/MAX17597 family also allows the designer to choose between voltage soft-start and current soft-start modes, useful in optoisolated designs. A programmable slope compensation scheme is provided to enhance the stability of the peak-current-mode control scheme. Hiccup-mode overcurrent protection and thermal shutdown are provided to minimize dissipation in overcurrent and overtemperature fault conditions.

Data is written to an 8-byte scratchpad, verified, and then copied to the EEPROM memory. As a special feature, the four memory pages can individually be write protected or put in EPROM-emulation mode, where bits can only be changed from a 1 to a 0 state. The DS2431 communicates over the single-conductor 1-Wire bus. The communication follows the standard 1-Wire protocol. Each device has its own unalterable and unique 64-bit ROM registration number that is factory lasered into the chip. The registration number is used to address the device in a multidrop, 1-Wire net environment. http://www.maxim-ic.com/datasheet/index.mvp/id/4272 Fri, 03 Feb 2012 00:00:00 -0000 DS1341, DS1342: Low-Current I²C RTCs for High-ESR Crystals http://www.maxim-ic.com/datasheet/index.mvp/id/6264 The DS1341/DS1342 low-current real-time clocks (RTCs) are timekeeping devices that provide an extremely low standby current, which permits longer life from a power supply. The DS1341/DS1342 support high-ESR crystals, which broaden the pool of usable crystals for the devices. The DS1341 uses a 6pF crystal, while the DS1342 uses a 12.5pF crystal. These devices are accessed through an I²C serial interface. Other features include two time-of-day alarms, two interrupt outputs, a programmable square-wave output, and a serial bus timeout mechanism. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either 24hr or 12hr format with an AM/PM indicator. The DS1341/DS1342 also include an input for synchronization. When a reference clock (e.g., 60Hz power line or GPS 1PPS) is present at the CLKIN pin and the enable external clock input bit (ECLK) is set to 1, the DS1341/DS1342 RTCs are frequency-locked to the external clock and the clock accuracy is determined by the external source. In case of external clock failure, the clock is switched to the crystal oscillator. The devices are available in lead(Pb)-free/RoHS-compliant, 8-pin µSOP or TDFN packages. The devices support a -40°C to +85°C extended temperature range. http://www.maxim-ic.com/datasheet/index.mvp/id/6264 Fri, 03 Feb 2012 00:00:00 -0000
