Overview
The TMP01FP is a low power, programmable temperature controller and sensor produced by Analog Devices Inc. It is designed to generate a voltage output proportional to absolute temperature and provide control signals from one of two outputs when the device exceeds or falls below specific temperature thresholds. The TMP01FP combines a band gap voltage reference with a pair of matched comparators, allowing for precise temperature sensing and control.
