Charger IC supports range of cell types Product News 3/28/2003 Post a comment When interfaced with a microcontroller, Linear Technology Corp.'s LTC4008, a 4-amp multicell, multichemistry battery pack charger IC, is said to be capable of charging nickel cadmium, nickel metal hydride and sealed lead-acid batteries as well as lithium-ion types.
Slick seven light up power management Product News 3/13/2003 Post a comment Raising the functionality bar for power-management chips, National Semiconductor Corp. has seven highly integrated mixed-signal ASICs for portable systems to meet the expanding needs of wireless applications, particularly cell phones.
PWM controller reduces power Product News 3/6/2003 Post a comment A programmable-frequency, current-mode pulse-width modulation controller from Fairchild Semiconductor International meets the International Energy Agency's 1-watt initiative for reducing standby power losses to below 1 W.
Driver targets automotive apps Product News 3/6/2003 Post a comment An intelligent stepper motor driver IC from Atmel Corp., the ATA6830, includes a smart travel operation control block that conserves space and simplifies designs by eliminating the need for a microcontroller to handle the cruise-control function.
Lithium-ion battery manager ready for microwatt work Product News 3/6/2003 Post a comment Responding to the need for maximum power management at the microwatt level in increasingly functional 2.5- and third-generation mobile handsets and PDAs, Texas Instruments Inc. is billing its bq270x0 chip, called bqJunior, as a fully integrated battery fuel gauge for systems powered by a single-cell lithium-ion or lithium-polymer battery.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
