ELECTRICAL CHARACTERISTICS (continued)

(VCC = +2.5V to +5.5V, RPULLUP = 100k

Ω (MAX6505/MAX6507 only), TA = -40°C to +125°C, unless otherwise noted. Typical values

are at TA = +25°C and VCC = +5V, unless otherwise noted.) (Note 1)

Note 1: 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.

Note 2: TALARM, TUNDER, and TOVER are factory-programmed temperature trip thresholds from -40°C to +125°C in 5°C increments.

Note 3: Temperature threshold hysteresis is defined as the difference from positive-going temperature thresholds minus the nega-

tive-going temperature thresholds.
