The 100µs maximum reset timeout is fast enough to catch supply glitches before downstream logic corrupts state, but long enough to ignore noise on a clean rail. ## Package and footprint constraints Cut Tape options are available for prototyping or low-volume builds.","metaTitle":"TPS37A543222DSKRQ1 Automotive Voltage Detector – TI, Active","metaDescription":"Texas Instruments TPS37A543222DSKRQ1 automotive voltage detector, 3.2V/5.4V window thresholds, -40°C to 125°C, 10-WSON.

These are fixed internal references — no external resistor divider sets the trip points."},{"question":"Is TPS37A543222DSKRQ1 a direct replacement for TPS37A543222DSKR?","answer":"The base product number is TPS37. The suffix DSKRQ1 indicates the 10-WSON package and automotive qualification. The DSKR variant (without Q1) is the non-automotive version. They are not drop-in replacements if the BOM requires AEC-Q100 certification."},{"question":"What is the reset timeout of TPS37A543222DSKRQ1?","answer":"The reset timeout is 100µs maximum. This is the period the output holds the reset signal low after the monitored voltage returns within the window."},{"question":"Is TPS37A543222DSKRQ1 automotive qualified?","answer":"Yes, it is part of the Automotive, AEC-Q100 series.
