TPS3703/TPS3703-Q1 Automotive Window Supervisor Texas Instruments TPS3703/TPS3703-Q1 Automotive High-Accuracy Window Supervisor is ideal for systems operating on low-voltage supply rails with narrow margin supply tolerances. The TPS3703-Q1 Window Supervisor is offered in a small 6-pin DSE package and does not require any external resistors for setting overvoltage and undervoltage reset thresholds, which further optimizes overall accuracy, cost, solution size and improves reliability for safety systems.
