The TPS310x and TPS311x families of supervisory circuits provide circuit initialization and timing supervision, primarily for DSP and processor-based systems.During power-on, RESET is asserted low when the supply voltage (VDD) becomes higher than 0.4 V. Thereafter, the supervisory circuit monitors V ? Precision Supply Voltage Supervision Range: 0.9 V, 1.2 V, 1.5 V, 1.6 V, 2 V, and 3.3 V\n? High Trip-Point Accuracy: 0.75%\n? Supply Current of 1.2 μA (Typical)\n? RESET Defined With Input Voltages as Low as 0.4 V\n? Power-On Reset Generator With a Delay Time of 130 ms\n? Push/Pull or Open-Drai;
