Product Summary
The tps3803-01dckr is a Voltage detector. The tps3803-01dckr provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems. The tps3803-01dckr has a fixed-sense threshold voltage VIT set by an internal voltage divider, whereas 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, the tps3803-01dckr 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 and Automotive Systems.
