The LTC3779 is a high performance buck-boost switching regulator controller that operates from input voltages above, below or equal to the output voltage. The constant frequency current mode architecture allows a phaselockable frequency of up to 600kHz, while an input/output constant current loop provides support for battery charging.?With a wide 4.5V to 150V input and output range and seamless transfers between operating regions, the LTC3779 is ideal for automotive, telecom and batterypowered systems.?The LTC3779 features a precision 1.2V reference and power good output indicator. The MODE pin can select between pulse-skipping mode or forced continuous mode of operation. Pulse-skipping mode offers high efficiency at light load while forced continuous mode operates at a constant frequency for noise sensitive applications. The PLLIN pin allows the IC to be synchronized to an external clock. The SS pin ramps the output voltage during start-up. Current foldback limits MOSFET heat dissipation during short-circuit conditions.Applications Industrial, Automotive, Medical, Military, Avionics

The AD8450 is a precision analog front end for testing andmonitoring battery cells. Referring to figure one, a precisionprogrammable gain instrumentation amplifier (PGIA)measures the battery’s charge/discharge current and aprogrammable gain difference amplifier (PGDA) measures thebattery’s voltage. Internal laser trimmed resistor networks setthe gains for the PGIA and the PGDA, optimizing the AD8450’sperformance over the rated temperature range. PGIA gains are26×, 66×, 133×, and 200×. PGDA gains are 0.2×, 0.27×,0.4×,and 0.8×.Voltages at the ISET and VSET inputs set the desired constantvoltage (CV) and constant current (CC) values. CC to CVswitching is automatic and transparent to the system.A TTL level logic input, MODE, selects between charge anddischarge modes (high for charge, low for discharge). An analogoutput, VCTRL, interfaces directly with ADI’s ADP1972 &ADP1974 PWM controllers.The AD8450 includes resistor programmable overvoltage andovercurrent detection and current sharing circuitry. Currentsharing is used to balance charge among multiple batteries.The AD8450 simplifies designs by providing excellent accuracy,performance over temperature, flexibility with functionality,and overall reliability in a space-saving package. The AD8450 isavailable in an 80 lead 14 mm ×14 mm × 1 mm LQFP packageand is rated at −40 °C to +85 °C operating temperature.APPLICATIONS Battery cell testing & formation Battery module testing

The ADBMS18181 is a multicell battery stack monitor that measures up to 18 series connected battery cells with a total measurement error of less than 3.0 mV. The cell measurement range of 0 V to 5 V makes the ADBMS1818 suitable for most battery chemistries. All 18 cells can be measured in 290 ?s, and lower data acquisition rates can be selected for high noise reduction. Multiple ADBMS1818 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each ADBMS1818 has an isoSPI? interface for high speed, RF immune, long distance communications. Multiple devices are connected in a daisy chain with one host processor connection for all devices. This daisy chain can be operated bidirectionally, ensuring communication integrity, even in the event of a fault along the communication path. The ADBMS1818 can be powered directly from the battery stack or from an isolated supply. The ADBMS1818 includes passive balancing for each cell, with individual PWM duty cycle control for each cell. Other features include an on-board 5 V regulator, nine general purpose I/O lines, and a sleep mode, where current consumption is reduced to 6 ?A.

The ADL8106 is a gallium arsenide (GaAs), pseudomorphic high electron mobility transfer (pHEMT), monolithic microwave integrated circuit (MMIC), wideband low noise amplifier that operates from 20 GHz to 54 GHz. The ADL8106 provides a gain of 21.5 dB, an output power for 1 dB compression (OP1dB) of 14 dBm, and a typical output third-order intercept (OIP3) of 21.5 dBm at 30 GHz to 44 GHz. The ADL8106 requires 120 mA from a 3 V supply voltage (VDD) and features inputs and outputs that are internally matched to 50 ?, facilitating integration into multichip modules (MCMs). All data is taken with the RFIN and RFOUT pads connected via one 0.076 mm (3 mil) wide gold ribbon bond of 0.076 mm to 0.152 mm (3 mil to 6 mil) minimal length.
