Battery-Protection IC said to reduces BMS Cost by 80% in Hybrid and Electric Vehicles
Maxim has introduced the MAX11080, a high-voltage, 12-channel battery-protection IC for high-cell-count lithium-ion (Li+) battery stacks. The first stackable fault monitor on the market, this device provides redundant cell monitoring to prevent Li+ batteries from exploding (thermal runaway). Up to 31 MAX11080s can be daisy-chained together to monitor as many as 372 cells. This capability prevents cascading electrical failures and eliminates the e...
Industry's Lowest Power Upstream Amplifier for DOCSIS 3.0
Maxim Integrated Products introduces the MAX3518, a DOCSIS(R) 3.0 upstream amplifier that combines the industry's lowest power consumption with optimal distortion performance. This device consumes a mere 1.25W when configured for 31dB of gain and +64dBmVout. Moreover, it consumes an ultra-low 25mW in transmit-disabled mode, while achieving a low, 10dB noise figure and 60dBc of harmonic distortion. The MAX3518's industry-low power consumption redu...
Maxim's Chipset Eliminates Costly Current Transformers in Polyphase Energy Meters
Maxim has introduced a chipset, the MAXQ3108 and DS8102, that reduces the bill of materials (BOM) cost of a polyphase energy meter. Together, the MAXQ3108 and DS8102 replace three high-cost current transformers with three low-cost shunts to save both cost and space.
Maxim's Shunt-Mode Audio Click-and-Pop Eliminator Saves Space and Cost
Maxim has introduced the MAX9892, a shunt-mode, audio click-and-pop eliminator designed for portable multimedia devices. This simple IC provides 35dB of click-and-pop suppression to eliminate the irritating audible artifacts generated during startup and shutdown cycles.
Fully Integrated Wide-Input Range Boost Regulators from Micrel
Micrel has introduced the MIC2605/6, two boost regulators operating at 1.2MHz (MIC2605) and 2MHz (MIC2606). Both devices supply up to 0.5A switch current. The devices, which complement Micrel's recently introduced MIC2601/2 family, are aimed at TV-tuners, broadband communications, TFT-LCD bias supplies, positive output regulators, SEPIC converters, DSL applications and local boost regulators. The ICs are currently available in volume quantitie...
ROHM Semiconductor Develops New Motor Driver LSI
Semiconductor manufacturer ROHM has developed the BD65491FV (1-channel) and BD65492MUV (2-channel) high-speed motor drivers for use in a broad range of digital camera lens drive and home appliance motor drive applications.
The Industry’s Smallest Single-Package Power Supply Modules
ROHM has recently announced the development of the BZ6A series of ultra-compact power supply modules that integrate an inductor, capacitors, and all the other components needed for power supply into a single package. The result is the smallest size* in the industry (2.3mm × 2.9mm × 1mm), making them suitable for high-density mounting applications.
ZMDI LED driver ICs boost lumen-per-watt efficiency while keeping Bill of Material low
ZMD AG today announced two high-performance devices to complement its family of LED driver integrated circuits. The ZLED7020 and the ZLED7030 LED driver ICs operate at up to 98% efficiency, thus helping to achieve the highest possible lumen-per-watt output in high brightness LED applications.
Torex - 1A, 0.5v Ultra-low Dropout Voltage Regulator With Soft-start
The new XC6602 series from Torex is a high speed and highly accurate LDO which can supply up to 1A of output current while consuming only 110µA. With the help of a bias voltage that can be set between 2.5V and 6.0V, the XC6602 operates with input voltages from 0.5V to 3.0V and is readily available with fixed output voltages from 0.5V to 1.8V in 0.1V increments.
1A, 0.5V ultra-LDO voltage regulator with programmable soft-start or programmable over current protection
The new XC6603/04 series from Torex is a high speed and highly accurate LDO family which can supply up to 1A of output current while consuming only 100µA. With the help of a bias voltage that can be set between 2.5V and 6.0V, the XC6603/04 operates with input voltages from 0.5V to 3.0V and is readily available with fixed output voltages from 0.5V to 1.8V in 0.1V increments.
