The RSTVDD output remains asserted 30mV Hysteresis to Provide Failsafe until the VDD voltage returns above its threshold. The • Very Low Quiescent Current: 3.5µA typ device also provides an additional RSTSENSE output for a SENSE input with adjustable thresholds • High Threshold Accuracy: 1% max and hysteresis. (0 °C to +85°C) The TPS3807 uses a precision reference to achieve • Open-Drain Reset Outputs 1% threshold accuracy. The TPS3807 has a very low • Temperature Range: –40°C to +85°C typical quiescent current of 3.5 µA, so it is well-suited • Ultra-Small SC70-5 Package to battery-powered applications. It is available in a small SC70-5 package, which is half the size of a SOT-23 package, and is fully specified over a temperature range of –40 °C to +85°C. • DSP, Microcontroller, or Microprocessor Applications Requiring User-Selected Delay Times • Notebook/Desktop Computers • PDAs and SmartPhones • Other Hand-Held Products • Portable, Battery-Powered Products • FPGA/ASIC Applications Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
