Product Summary

The TPS3802K33DCKR is a microprocessor supervisory circuit monitor system. It voltages from 0.4V to 5.0V, asserting an open drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output of the TPS3802K33DCKR remains low for the user adjustable delay time after the SENSE voltage and manual reset (MR) return above their thresholds. The applications of the TPS3802K33DCKR include DSP or Microcontroller Applications, Notebook/Desktop Computers, PDAs/Hand-Held Products, Portable/Battery-Powered Products, FPGA/ASIC Applications.
