Product Summary

The TPS3803-01DCKR supervisory circuit provides circuit initialization and timing supervision, primarily for DSPs and processorbased systems. The TPS3803-01DCKR has an adjustable SENSE input that can be configured by two external resistors. In addition to the fixed sense threshold monitored at VDD, it provides a second adjustable SENSE input. RESET is asserted in case any of the two voltages drops below VIT. The applications of the TPS3803-01DCKR include Applications Using DSPs, Microcontrollers, or Microprocessors, Wireless Communication Systems, Portable/Battery-Powered Equipment, Programmable Controls, Intelligent Instruments, Industrial Equipment, Notebook/Desktop Computers, Automotive Systems.
