This current is mirrored and used to generate a or below a specific temperature range. Both the high/low hysteresis offset voltage of the appropriate polarity after a temperature trip points and hysteresis (overshoot) band are comparator has been tripped. The comparators are connected determined by user-selected external resistors. For high volume in parallel, which guarantees that there is no hysteresis overlap production, these resistors are available on board. and eliminates erratic transitions between adjacent trip zones. The TMP01 consists of a band gap voltage reference combined The TMP01 utilizes proprietary thin-film resistors in conjunc- with a pair of matched comparators.
