TPS3839K33DBZR Description


The TPS3839K33DBZR devices are voltage supervisory circuits that operate at extremely low currents (about 150 nA). Every time the Vdd supply voltage falls below the factory-trimmed reset threshold voltage, both devices start an active-low reset signal. After the VDD voltage above the threshold voltage and hysteresis, the reset output remains low for 200 ms (typically). Fast transients on the VDD pin are ignored by these devices by design.



TPS3839K33DBZR Features


  • 150 nA is the ultralow supply current (Typical)

  • Supply Voltage Range: 0.9 to 6.5 V

  • Valid Reset for VDD Over 0.6 V

  • Output for Push-Pull RESET

  • Reset threshold voltages that have been factory-trimmed

  • Temperature range: -40 to 85 degrees Celsius
