FUNCTION

SMBus Accelerator Pull-Ups
Both SCL and SDA have SMBus accelerator circuits which
reduce the rise time on systems with significant capaci-
tance on the two SMBus signals. The dynamic pull-up
circuitry detects a rising edge on SDA or SCL and applies
2mA to 5mA pull-up to V
nal pull-up resistors are still required to supply DC cur-
rent). This action allows the bus to meet SMBus rise time

signal. The improved rise time will benefit all of the devices
which use the SMBus, especially those devices that use
the I
only pull to V
compliant to the SMBus specifications may still have rise
time compliance problems if the SMBus pull-up resistors
are terminated with voltages higher than V
