Summary

The Texas Instruments TL7700-SEP is a bipolar integrated circuit designed to be used as a reset controller in microprocessor and microcomputer systems.

It features a highly stable circuit function with a 1.8-40 V supply voltage and a SENSE voltage that can be set to any value greater than 0.5 V using 2 external resistors.

The system has a minimum supply current that allows portable battery operation and may be used with AC line operation.

The TL7700-SEP device is also designed to operate effectively in the temperature range –55°C to 125°C.

Applications

  • Low Earth orbit (LEO) space applications
  • Power supervisor for satellites
  • Supervise DPS, MCUs, FPGAs, and ASICs
