Digital Temperature Sensor and Thermal

Watchdog with 2-Wire Interface

ELECTRICAL CHARACTERISTICS (continued)

(+VS = +3.0V to +5.5V, unless otherwise noted. Temperature accuracy specifications apply for +VS = 3.3V for versions with “-3” in

the suffix and for +VS = 5V for versions with “-5” in the suffix. TA = -55°C to +125°C, unless otherwise noted. Typical values are at

+VS = +5V, TA = +25°C.) (Notes 4, 5)

All parts operate properly over the 3V to 5.5V supply voltage range. The devices are tested and specified for rated

accuracy at their nominal supply voltage.

All parameters are measured at TA = +25°C. Values over the temperature range are guaranteed by design.

There is no industry-wide standard for temperature accuracy specifications. Maxim’s standard is 6-σ. The 3-σ specifica-

tion is included to allow easier comparison to products built by manufacturers who use different standards.

This specification indicates how often temperature data is updated. The devices can be read at any time without regard to

conversion state, while yielding the last conversion result.

For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy due to internal heating.

OS delay is user programmable up to 6 over-limit conversions before OS is set to minimize false tripping in noisy environ-

ments.

Guaranteed by design.

Default values set at power-up.

All timing specifications are guaranteed by design.

Unless otherwise noted, these specifications apply for +VS = +5VDC for LIM75BIM-5 and LIM75BIMM-5 and +VS =

+3.3VDC for LIM75BIM-3 and LIM75BIMM-3. CL (load capacitance) on output lines = 80pF, unless otherwise specified.

The switching characteristics of the LM75 fully meet or exceed the published specifications of the I2C bus. These parame-

ters are the timing relationships between SCL and SDA signals related to the LM75. They are not I2C bus specifications.

Holding the SDA line low for a time greater than tTIMEOUT causes the device to reset SDA to the IDLE state of the

serial bus communication (SDA set high).
