_______________Detailed Desc ription
The MAX6575L/H low-cost, low-current (150μA typ)
temperature sensor is ideal for interfacing with micro-
controllers or microprocessors. The MAX6575L/H is a
monostable, externally triggered temperature sensor
that uses a Temp
→
Delay conversion to communicate
with a μP over a single I/O line. Time-select pins (TS1,
TS0) permit the internal temperature-controlled oscilla-
tor (TCO) to be scaled by four preset timeout multipli-
ers, allowing eight separate temperature sensors to
share one I/O line. Different sensors on the same I/O
line will use different timeout multipliers to avoid over-
lapping signals.
Operating the MAX 6575L/H
Figure 1 illustrates the timing for the MAX6575L/H.
When the device is powered up, it assumes a ready
state where it awaits an external trigger at the I/O pin.
The I/O pin of the MAX6575L/H has an open-drain out-
put structure that requires a pull-up resistor to maintain
the proper logic levels. Once the I/O pin is pulled low
and then released, control of the I/O pin is transferred
to the MAX6575L/H. The temperature conversion
begins on the falling edge of the externally triggered
pulse. The I/O line is pulled low at a later time. That time
is determined by the device temperature and the Time
Select pins (TS1, TS0). The I/O line remains low for
5Tμs, where T is the temperature in degrees Kelvin. The
temperature of the device is represented by the edge-
to-edge delay of the externally triggered pulse and the
falling edge of the subsequent pulse originating from
the device. The device can be manually reset by
pulling the I/O line low for more than t
RESET
(16ms
max). The device will automatically reset after a maxi-
mum delay of 520ms, at which point it will again be in a
ready state awaiting a start pulse.
Definition of Terms:
t
RESET
: Time I/O must be externally pulled low to guar-
antee the MAX6575L/H is in a ready state
awaiting external trigger. (Part will assume a
ready state after 520ms without a reset pulse.)
t
SETUP
: Time I/O must be high prior to a start pulse.
t
START
: Trigger pulse which starts the on-chip timing
sequence on its falling edge.
t
Dx
:
Timing delay between the falling edge of the
start pulse and the falling edge initiated by
CHIP#x.
t
Lx
:
I/O pulse low time (5Tμs).
t
READY
:Time after falling edge of start pulse when the
MAX6575L/H will reset itself and await the next
external trigger.
The temperature, in degrees Celsius, may be calculat-
ed as follows:
T(°C) = [t
Dx
(μs) / timeout multiplier(μs/°K)] - 273.15°K
