XTR650 is a family of highly stable, small footprint and versatile timers designed for extreme reliability and temperature applications such as accurate time delays or frequency generators. Being able to operate from supply voltages from 2.9V to 5.5V, the XTR650 timers can generate timing periods from some hundreds of nanoseconds and oscillations with duty-cycles from virtually zero to 100%, overcoming the limitations of existing 555.
Other features include the availability of high current complementary and non-overlapping outputs, complementary open-drain outputs, integrated timing capacitor of 200pF for reduced bill-ofmaterial (BoM), and integrated coarse temperature sensor.
Especial design techniques were used allowing the XTR650 parts to offer a precise, robust and reliable operation in critical applications. Full functionality is guaranteed from -60°C to +230°C, though operation well below and above this temperature range is achieved.
XTR650 has been designed to reduce system cost and ease adoption by reducing the learning curve and providing smart and easy to use features.
Parts from the XTR650 family are available in ruggedized SMT and thru-hole packages, as well as bare dies.
