Overview
The TMP01FPZ, produced by Analog Devices Inc., is a low-power, programmable temperature controller and sensor. This device generates a voltage output proportional to absolute temperature and provides control signals from one of two outputs when the temperature exceeds or falls below user-set thresholds. The TMP01FPZ combines a band gap voltage reference with a pair of matched comparators, allowing for precise temperature sensing and control. It operates on a single supply voltage ranging from 4.5 V to 13.2 V and is available in 8-pin mini PDIP, SOIC, and TO-99 packages.
