QFJ3529 Datasheet
QFJ3529 Price In addition to the standard output configuration, the outputs of the ispLSI 2128VL are individually program- mable, either as a standard totem-pole output or an open-drain output. The totem-pole output drives the specified Voh and Vol levels, whereas the open-drain output drives only the specified Vol. The Voh level on the open-drain output depends on the external loading and pull-up. This output configuration is controlled by a pro- g rammable fuse. The default config u ration is a totem-pole configuration. The open-drain/totem-pole option is se- lectable through the ispDesignEXPERT software tools. For each bridge the PHASE input controls load current polarity by selecting the appropriate source and sink driver pair. For each bridge the ENABLE input, when held high, disables the output drivers. Spe- cial power-up sequencing is not required. Internal circuit protection includes thermal shutdown with hysteresis, transient-suppression diodes, and crossover-current protection. |
