Figure 1. Applications Using the TPS3307 Family

DESCRIPTION

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.

During power-on, RESET is asserted when the supply voltage V_DDbecomes higher than 1.1V. Thereafter, the

supply voltage supervisor monitors the SENSEn inputs and keeps RESET active as long as SENSEn remain

below the threshold voltage V_IT+

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
