Description

The TPS3307, TPS3307-18 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.

Features

• Triple Supervisory Circuits for DSP and Processor-Based Systems

• Power-On Reset Generator With Fixed Delay Time of 200ms, No External Capacitor Needed

• Temperature-Compensated Voltage Reference

• Maximum Supply Current of 40µA

• Supply Voltage Range: 2V to 6V

• Defined RESET Output From VDD ≥ 1.1V

• Temperature Range : – 40°C to +85°C
