typical applications

Figure 1 lists some of the typical applications for the

TPS3307 family, and a schematic diagram for a

processor-based system application. This

application uses TI part numbers TPS3307−18 and

TMS470R1Vxxx.

description

The TPS3307-18 is a micropower supply voltage supervisor designed for circuit initialization primarily in

automotive DSP and processor-based systems, which require more than one supply voltage.

The TPS3307-18 is designed for monitoring three independent supply voltages: 3.3 V/1.8 V/adj,. The adjustable

SENSE input allows the monitoring of any supply voltage >1.25 V.

The various supply voltage supervisors are designed to monitor the nominal supply voltage as shown in the

following supply voltage monitoring table.
