TMP01FSZ-REEL7

TMP01FSZ-REEL7 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. The reference provides both a constant 2.5V output and a voltage proportional to absolute temperature (VPTAT) which has a precise temperature coefficient of 5mV/K and is 1.49V (nominal) at 25°C. It is used in applications 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.
