OPERATIOU
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
DD
for approximately 1
μ
s (exter-
nal pull-up resistors are still required to supply DC cur-
rent). This action allows the bus to meet SMBus rise time
requirements with as much as 150pF on each SMBus
signal. The improved rise time will benefit all of the devices
which use the SMBus, especially those devices that use
the I
2
C logic levels. Note that the dynamic pull-up circuits
only pull to V
DD
, so some SMBus devices that are not
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
DD
.
