ELECTRICAL CHARACTERISTICS (continued)
(V
CC
= +3.3V, configuration byte register = X8h, T
A
= -55°C to +125°C, unless otherwise noted.) (Note 5)
Note 1: Guaranteed, but not 100% tested.
Note 2: A remote diode is any diode-connected transistor from Table 7. T
R
is the junction temperature of the remote diode. See
Remote Diode Selection for remote-diode forward voltage requirements. Temperature specification guaranteed for a diode
with ideality factor (M
TR
= 1.013). Additional error = (1.013/M - 1)
✕
273 + Temp where M = Ideality of remote diode used.
Note 3: The SMBus logic block is a static design that works with clock frequencies down to DC. While slow operation is possible, it
violates the 10kHz minimum clock frequency and SMBus specifications and may monopolize the bus.
Note 4: Note that a transition must internally provide at least a hold time to bridge the undefined region (300ns max) of SMBCLK’s
falling edge.
Note 5: Specifications from -55°C to +125°C are guaranteed by design, not production tested.
