LTC2941 LTC2942 battery gas gauges with an I2C interface

LTC2941/LTC2942 introduced by Linear Technology Corporation are battery gas gauges with an I2C interface for 2.7V to 5.5V systems. The LTC2941/LTC2942 use a continuous-time analog integrator to measure charge directly, resulting in minimal offset and gain error and better overall charge accuracy.

SiC762CD integrated power stage solution

The SiC762CD is an integrated power stage solution that contains PWM optimized n-channel MOSFETs (high side and low side) and a full featured MOSFET driver IC.

The SiC762CD provide up to 35 A continuous output current and operates from an wide input voltage range of 3 V to 27 V.

The SiC762CD manufactured by the Vishay Siliconix use integrated MOSFETs optimized to provide output voltages ranges from 0.8 V to 2.0 V with a nominal input

voltage of 24 V but also the device can deliver very high power at 5 V output for ASIC applications.

Main features of the SiC762CD power stage are : Integrated Gen III MOSFETs and DrMOS compliant gate driver IC ,  Enables Vcore switching at 1 MHz , easily achieve > 90 % efficiency in multi-phase  , tri-state PWM input function prevents negative output voltage swing ,  5 V logic levels on PWM , MOSFET threshold voltage optimized for 5 V driver bias supply , automatic skip mode operation (SMOD) for light load efficiency , under-voltage lockout , built-in bootstrap schottky diode .
