HT7070A Voltage Detector

The HT70XX series comprises a collection of three-terminal low-power voltage detectors constructed using CMOS technology. Each voltage detector within the series is designed to detect a specific fixed voltage within the range of 2.2V to 7V. These detectors feature a high-precision, low-power consumption standard voltage source, a comparator hysteresis circuit, and an output driver. The use of CMOS technology guarantees minimal power consumption. While primarily intended as fixed voltage detectors, these devices can be adapted with external components to detect user-defined threshold voltages, applicable only to the NMOS open-drain type. The datasheet for the HT7070A is identical to that of the HT7070A.

The HT70XX series voltage detectors are versatile components suitable for a range of applications, including battery-powered devices, microcontroller systems, and power management circuits. The three-terminal configuration simplifies integration into existing designs, allowing for straightforward connections to power supply lines and control circuits.

The high-precision voltage source ensures accurate detection of the specified threshold voltages, making these devices ideal for applications requiring reliable voltage monitoring. The comparator hysteresis circuit enhances stability by preventing false triggering due to noise or rapid voltage fluctuations, which is critical in environments with varying electrical characteristics.

The output driver of the HT70XX series is designed to interface seamlessly with other components in a circuit, providing a clear signal when the detected voltage level crosses the predefined threshold. This feature is particularly beneficial in systems where timely response to voltage changes is essential, such as in over-voltage protection or under-voltage lockout scenarios.

The adaptability of the HT70XX series to user-defined threshold voltages through external components expands its functionality, allowing designers to customize the voltage detection levels to meet specific application requirements. This capability, combined with the low power consumption characteristic of CMOS technology, makes the HT70XX series an excellent choice for energy-sensitive applications.
