ROHM Semiconductor offers a broad lineup of ultra-compact, low current consumption thermostat output temperature sensors optimized for temperature monitoring and overheating protection in compact devices of all types. The BDJxxxxHFV series integrates a temperature detection element, constant current circuit, and high precision reference power source in a single chip. Additional features include low current consumption (7.5 μA – 50 percent less than conventional products), built-in power down function, high analog output temperature sensitivity, precision thermostat, detection temperature hysteresis, and precise analog output (±2.5°C maximum). Multiple models are available in a range of detection temperatures, from 55°C to 90°C in 5°C intervals. The units are available in a compact HVSOF5 package – 70 percent smaller than conventional SSOP5 packages.
