TPS37043BJOFDDFRQ1 Supervisor Open Drain or Open Collector 3 Channel TSOT-23-8
Texas Instruments TPS3704x/TPS3704x-Q1 Precision Voltage Supervisor
Texas Instruments TPS3704x/TPS3704x-Q1 Precision Voltage Supervisor is a low-power precision window or standard voltage supervisor that can be configured as a quad, triple, dual, or single channel. Each channel has a threshold accuracy of ±1% in an 8-pin (1.6mm x 2.9mm) SOT-23 package offering a small solution size. The TPS3704x/TPS3704x-Q1 includes a very accurate threshold detection with high resolution, 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 (tD options from 20µs to 1200ms) prevent false reset signals when monitoring multiple voltage rails.
The Texas Instruments TPS3704x/TPS3704x-Q1 does not require any external resistors for setting the over and under voltage 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. The SENSEx pins support the optional use of external resistors. Each channel on the TPS3704x/TPS3704x-Q1 can be customized to its own over and under-voltage window detection with an upper and lower threshold tolerance that can be symmetric or asymmetric. The TPS3704x-Q1 devices are AEC-Q100 qualified for automotive applications.
