Maximum R
L
Value vs. Bus Capacitance (C
BUS
) for an I
2
C Bus
Select Address (SA0, SA1, SA2)
These input signals are used to set the value that is to be looked for on the three least significant bits (b3, b2, b1) of the 7-bit Slave Address. In the
end application, SA0, SA1 and SA2 must be directly (not through a pull-up or pull-down resistor) connected to V
DDSPD
or V
SSSPD
to establish the
Slave Address. When these inputs are not connected, an internal pull-down circuitry makes (SA0, SA1, SA2) = (0, 0, 0).
The SA0 input is used to detect the V
HV
voltage, when decoding an SWP or CWP instruction. Refer to the I
2
C Operating Modes table for decoding
details.
EVENT
The TSE2002B3C EVENT
pin is an open drain output that requires a pull-up to V
DDSPD
on the system motherboard or integrated into the master
controller. The TSE2002B3C EVENT
pin has three operating modes, depending on configuration settings and any current out-of-limit conditions.
These modes are Interrupt, Comparator, or TCRIT Only.
In Interrupt Mode the EVENT
pin will remain asserted until it is released by writing a '1' to the Clear Event bit in the Status Register. The value to
write is independent of the EVENT
polarity bit.
In Comparator Mode the EVENT
pin will clear itself when the error condition that caused the pin to be asserted is removed. When the temperature
is compared against the TCRIT limit, then this mode is always used.
Finally, in the TCRIT Only Mode the EVENT
pin will only be asserted if the measured temperature exceeds the TCRIT Limit. Once the pin has been
asserted, it will remain asserted until the temperature drops below the TCRIT Limit minus the TCRIT hysteresis. The next figure illustrates the opera-
tion of the different modes over time and temperature.
Systems that use the active high mode for EVENT
must be wired point to point between the TSE2002B3C and the sensing controller. Wire-OR
configurations should not be used with active high EVENT
since any device pulling the EVENT
signal low will mask the other devices on the bus. Also
note that the normal state of EVENT
in active high mode is a 0 which will continually draw power through the pull-up resistor.
