This document describes the features and characteristics of the TMP01 low power programmable temperature controller produced by Analog Devices, including temperature sensor and voltage reference, temperature-proportional voltage output, user-programmable temperature trip points and hysteresis, 20mA open collector trip point outputs, and suitability for single-supply operation.
The TMP01 is a low‑power programmable temperature controller that generates a voltage proportional to absolute temperature and provides open‑collector trip point outputs for over/under temperature alarms. It includes a 2.5 V band‑gap reference, a VPTAT output with a 5 mV/K scale factor, and user‑programmable hysteresis and set‑point resistors.
The document lists electrical specifications, absolute maximum ratings, package options (8‑pin DIP, SOIC, TO‑99), and typical performance curves. It also covers programming methods, error sources, safety considerations, and mechanical dimensions for board‑level integration.
| Output Voltage (VPTAT) at 25 °C, No Load | 1.49 V |
|---|---|
| Scale Factor | 5 mV/K |
| Open‑Collector Output Current (continuous) | 20 mA (max 50 mA) |
| Power Dissipation at V+ = 5 V | 2.0 mW to 2.5 mW |
The open‑collector outputs can sink 20 mA continuously, with an absolute maximum rating of 50 mA.
The device operates from –55 °C to +150 °C.
The temperature‑to‑voltage scale factor is 5 mV per Kelvin.
