TMP01ESZ

TMP01 is a temperature sensor that generates a voltage output proportional to absolute temperature and a control signal from one of two outputs when the device is either above or below a specific temperature range. Both the high/low temperature trip points and hysteresis (overshoot) band are determined by user-selected external resistors. It consists of a band gap voltage reference combined with a pair of matched comparators. Hysteresis is also programmed by the external resistor chain and is determined by the total current drawn out of the 2.5V reference. This current is mirrored and used to generate a hysteresis offset voltage of the appropriate polarity after a comparator has been tripped. It is used in application such as over/under temperature sensor and alarm, board-level temperature sensing, temperature controllers, electronic thermostats, thermal protection, HVAC systems, industrial process control, remote sensors etc.
