Texas Instruments 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 external resistors for setting overvoltage and undervoltage reset thresholds, further optimizing overall accuracy, cost, and solution size and improving reliability for safety systems.

The low threshold hysteresis, internal glitch immunity, and noise filters prevent false reset resulting from erroneous signals when the monitored voltage supply is in its normal range of operation. Each device is designed with two reset time delays that use the Capacitor Time (CT) pin to configure by connecting to a capacitor.

A separate SENSE input and VDD pin allow for the redundancy sought by high-reliability systems. The TPS3703/TPS3703-Q1 has a low typical quiescent current specification of 4.5µA (typical). The Texas Instruments TPS3703-Q1 devices are AEC-Q100 qualified for automotive applications.
