MM1524N

MITSUMI Open collector output temperature switch MM1523 N/MM1524 N Open collector output temperature switch Monolithic IC MM1523 N/MM1524 N Outline This IC is a temperature switch that emits a logic signal when chip temperature during load reaches the set detection temperature. It is composed of a temperature detection circuit and a comparator. Features 1. Detection temperature precision ±3˚C max. 2. Detection temperature hysteresis 10˚C typ. 3. Detection temperature is lined up in 10˚C steps by trimming in the +50˚C ~ +100˚C range. 4. Active low output/MM1523 N 5. Active high output/MM1524 N 6. Consumption current 90µA (when OFF/typ.) 7. Operating power voltage range +2.7~+10.0V 8. Operating temperature range -40~+125˚C Package SOT-25A Applications 1. CPU heat protection 2. Battery charger heat protection 3.
