Dynamic avalanche in bipolar power devices
WebThis device ensures a very low static and dynamic power consumption across the entire V CC range from 0.8 V to 3.6 V. This device is fully specified for partial Power-down applications using I OFF. The I OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. WebCurrent-induced avalanche (CIA), defined as dynamic avalanche triggered by the current caused by the initially generated electron-hole pairs, subsequently occurs at the peaks of the electric field. In this situation, the CIA can trigger secondary breakdown of a parasitic bipolar transistor, eventually leading to SEB.
