This application uses TI part numbers TPS3307-33 and MSP430C325. Figure 1. Applications Using the TPS3307 Family The TPS3307 family is a series of micropower supply voltage supervisors designed for circuit initialization primarily in DSP and processor-based systems, which require more than one supply voltage. The product spectrum of the TPS3307-xx is designed for monitoring three independent supply voltages: 3.3V/1.8V/adj, 3.3V/2.5V/adj or 3.3V/5V/adj. The adjustable SENSE input allows the monitoring of any supply voltage >1.25V. The various supply voltage supervisors are designed to monitor the nominal supply voltage as shown in the following supply voltage monitoring table.
