Figure 28. Daisy-Chain Signal at Input to the Microcontroller
Before the start pulse reaches a TMP05/TMP06 part in the
daisy chain, the device acts as a buffer for the previous tempera-
ture measurement signals. Each part monitors the PWM signal
for the start pulse from the previous part. Once the part detects
the start pulse, it initiates a conversion and inserts the result at
the end of the daisy-chain PWM signal. It then inserts a start
pulse for the next part in the link. The final signal input to the
microcontroller should look like Figure 28. The input signal on
Pin 2 (IN) of the first daisy-chain device must remain low until
the last device has output its start pulse.
If the input on Pin 2 (IN) goes high and remains high, the
TMP05/TMP06 part powers down between 0.3 s and 1.2 s later.
The part, therefore, requires another start pulse to generate
another temperature measurement. Note that, to reduce power
dissipation through the part, it is recommended to keep Pin 2
(IN) at a high state when the part is not converting. If the IN
pin is at 0 V, then the OUT pin is at 0 V (because it is acting as a
buffer when not converting), and drawing current through
either the pull-up MOSFET (TMP05) or the pull-up resistor
(TMP06).
TMP05 OUTPUT
The TMP05 has a push-pull CMOS output (Figure 29) and
provides rail-to-rail output drive for logic interfaces. The rise
and fall times of the TMP05 output are closely matched, so that
errors caused by capacitive loading are minimized. If load
capacitance is large (for example, when driving a long cable), an
external buffer might improve accuracy.
An internal resistor is connected in series with the pull-up
MOSFET when the TMP05 is operating in one shot mode.

TMP06 OUTPUT
The TMP06 has an open-drain output. Because the output
source current is set by the pull-up resistor, output capacitance
should be minimized in TMP06 applications. Otherwise,
unequal rise and fall times skew the pulse width and introduce
measurement errors.
