Product Summary
The TPS3306-18DR is a dual processor supervisory circuit with power-fail. It is designed for circuit initialization which require two supply voltages, primarily in DSP and processor-based systems. The TPS3306-18DR integrates a watchdog timer that is periodically triggered by a positive or negative transition of WDI. The applications of the TPS3306-18DR include: Multivoltage DSPs and Processors, Portable Battery-Powered Equipment, Embedded Control Systems, Intelligent Instruments, Automotive Systems.
