The LTC4311ISC6#TRPBF is a low voltage I2C\/SMBus accelerator from Analog Devices (formerly Linear Technology) that improves bus rise times for heavily loaded I2C buses. Operating from 1.6V to 5.5V, it provides slew-limited active pull-up currents during positive bus transitions to enhance data transmission reliability beyond the 400pF I2C specification limit.<\/p>\n

It provides slew-limited active pull-up currents during positive transitions, while disabling the currents during negative transitions to improve low-state noise margins. The auto-detect standby mode reduces supply current when both SCL and SDA are high.","working_principle":"The LTC4311 monitors the SCL and SDA bus lines. During positive-going transitions, it provides additional slew-limited pull-up current to overcome bus capacitance and achieve faster rise times. During negative-going transitions and steady-state low levels, the pull-up currents are disabled to improve low-state noise margins and avoid interference with bus drivers. When both bus lines are high, the device enters auto-detect standby mode consuming less than 5uA. The slew-limited current prevents excessive ringing on the bus.","pin_description":"
