具有看门狗计时器的超低电源电流、电压监控器

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;
