Description
AI
The TPS3704x is a low-power precision window or standard voltage supervisor that can be configured as a quad, triple, or dual channel. Each channel has a threshold accuracy of ±1% in an 8-pin (1.6 mm x 2.9 mm) SOT-23 package offering a small solution size. The TPS3704x includes a very accurate threshold detection, with high resolution, that is ideal for systems that operate on low-voltage supply rails and have narrow margin supply tolerances. Built-in low threshold hysteresis and a fixed reset delay prevent false reset signals when monitoring multiple voltage rails.
The TPS3704x does not require any external resistors for setting the over and undervoltage reset thresholds, which further optimizes overall high accuracy, cost, solution size, and improves reliability for safety systems.
Separate VDD and SENSEx pins allow monitoring of rail voltages other than VDD or can be used as a push-button input. Optional use of external resistors are supported by the SENSEx pins. Each channel on the TPS3704x can be customized to its own over and undervoltage window detection with an upper and lower threshold tolerance that can be symmetric or asymmetric.
