Features

an integrated start-up sequence for VBOOST/VLOGIC, VOFF, then VON or for VLOGIC, VOFF, VBOOST, and VON. The latter requires a single external transistor. The timing of the start-up sequence is set using an external capacitor. EL7586A features an immediately-enabled VLOGIC output which is independent of EN input. The VLOGIC output will be switched off if a fault is detected and the power supply needs to be recycled to reset this condition. Both the EL7586 and EL7586A are pin-compatible, come in the 20 Ld 4x4 QFN package, and are specified for operation over the -40°C to +85°C temperature range..
