TelCom Semiconductor TC625

The TC625 is a monolithic temperature sensor that generates a pulse train, the high and low times of which vary in direct proportion to the temperature of the device. This technique allows temperature to be accurately measured by the host microcontroller without an A/D converter, and with only a single I/O port pin. The overall accuracy is ±1.5°C typical over the rated measurement range of – 25°C to +100°C.

GENERAL DESCRIPTION

Unlike voltage output temperature sensors, the digital output of the TC625 offers superior immunity to system noise and does not require an A/D converter. Unlike two wire serial temperature sensors, the TC625 communicates over a single wire, and without serial protocol overhead. The TC625 operates from supply voltages as low as 2.7V. Open drain (TC625N) and complimentary (TC625C) output configurations are available. The TC625 is available in TO-92 and SOT-23A-5 packages.
