The TPS3779 and TPS3780 are a family of high-accuracy, two-channel voltage detectors with low-power and small solution size. The SENSE1 and SENSE2 inputs include hysteresis to reject brief glitches, ensuring stable output operation without false triggering. This family offers different factory-set hysteresis options of 0.5%, 1%, 5%, or 10%.

The TPS3779 and TPS3780 have adjustable SENSE inputs that can be configured by an external resistor divider. When the voltage at the SENSE1 or SENSE2 input goes below the falling threshold, OUT1 or OUT2 is driven low, respectively. When SENSE1 or SENSE2 rises above the rising threshold, OUT1 or OUT2 goes high, respectively.

The devices have a very low quiescent current of 2 µA (typical) and provide a precise, space-conscious solution for voltage detection suitable for low-power system-monitoring and portable applications. The TPS3779 and TPS3780 operate from 1.5 V to 6.5 V, over the –40°C to 125°C temperature range.

參考設計

TIDEP-0091 — 77 GHz 液位發送器功率最佳化參考設計

TIDEP-0091 強調 IWR14xx 76 至 81GHz 毫米波感測器的功耗最佳化策略,適用於儲槽液位探查應用,位移感測器,4 至 20mA 感測器,以及其他低功耗應用,以最小功率範圍提供高準確度偵測範圍。在這些應用中,系統通常會以低電壓資料線路運作,提供的功率通常低於操作功耗。工作循環對於降低平均功率以滿足電源輸入限制至關重要。可透過 IWR14xx 裝置的 MSP432 外部工作循環實現功耗最佳化,以進行定期感測。此外,此 參考設計也提供一維範圍偵測的樣本配置。
