Key Features
- 65 V maximum input voltage supports direct monitoring of 12 V, 24 V, and 48 V automotive bus rails without external voltage dividers
- Window under/over-voltage supervisor with programmable reset delay protects sensitive ECU loads from transient voltage excursions on harsh automotive power buses
- AEC-Q100 automotive qualification in a compact TSSOP-14 package ensures reliable operation across the full -40 °C to +125 °C automotive temperature range
Applications
The TPS37A010122DYYRQ1 is designed for automotive ECUs, ADAS modules, and 48 V mild-hybrid systems that require both under-voltage and over-voltage monitoring up to 65 V on a single device. Its programmable time-delay reset function prevents false resets during engine cranking transients, protecting downstream microcontrollers and FPGAs. The AEC-Q100 qualification and TSSOP-14 package make it a space-efficient drop-in supervisor for industrial 24 V power supplies and EV battery management front-ends as well.

Frequently Asked Questions
What input voltage range does the TPS37A010122DYYRQ1 support for automotive bus monitoring?
The TPS37A010122DYYRQ1 monitors supply rails up to 65 V, covering 12 V lead-acid, 24 V truck bus, and 48 V mild-hybrid automotive systems on a single device. Its window supervisor architecture generates a reset signal whenever the monitored voltage falls below or rises above the configured thresholds, protecting ECU loads from both under-voltage and over-voltage faults.
How does the programmable reset time-delay of the TPS37A010122DYYRQ1 help during engine cranking?
During engine cranking, automotive bus voltages can dip below 6 V for 50 ms to 200 ms. The programmable reset delay of the TPS37A010122DYYRQ1 allows the designer to set an ignore window longer than these transients, preventing nuisance resets on the downstream microcontroller and ensuring the ECU resumes normal operation immediately after the voltage recovers.
Which automotive qualification grade does the TPS37A010122DYYRQ1 carry, and what temperature range does it cover?
The TPS37A010122DYYRQ1 carries AEC-Q100 Grade 1 qualification, covering operation from -40 °C to +125 °C junction temperature. This grade meets the thermal and reliability screening requirements of powertrain, body, and chassis ECU applications where components are exposed to under-hood heat cycles throughout a vehicle lifetime of 15 years or more.
