Key Features
- Dual-channel under/overvoltage supervisor monitoring up to 65 V rails with adjustable thresholds and programmable reset delay for automotive 12 V and 48 V system protection
- Ultra-low quiescent current design minimizing standby power drain in always-on automotive ECU power domains operating over -40°C to +125°C
- AEC-Q100 qualified 10-pin SON package enabling compact integration in body control modules, ADAS, and EV battery management system PCBs
Applications
TPS38A010122DSKRQ1 is used in automotive ECU power sequencing circuits, 48 V mild-hybrid battery management systems, and ADAS domain controllers requiring dual-rail voltage monitoring with fault reset output. Its 65 V input rating supports direct monitoring of automotive 12 V and 48 V bus rails without external voltage dividers, while the programmable reset delay prevents nuisance resets during transient load events. The compact 10-pin SON package integrates two complete supervisor channels for space-constrained automotive PCB layouts meeting AEC-Q100 reliability requirements.

Frequently Asked Questions
What voltage rails can TPS38A010122DSKRQ1 monitor directly, and does it support 48 V automotive systems?
TPS38A010122DSKRQ1 monitors input voltages up to 65 V directly, covering both 12 V standard automotive bus and 48 V mild-hybrid system rails without requiring external resistor dividers. Its dual-channel architecture allows simultaneous monitoring of 2 independent voltage rails with adjustable under/overvoltage thresholds in a single 10-pin SON device operating from -40°C to +125°C.
How does the programmable reset delay in TPS38A010122DSKRQ1 help prevent nuisance resets in automotive ECUs?
TPS38A010122DSKRQ1 includes a programmable reset delay set by an external capacitor, allowing designers to filter out voltage transients shorter than the configured delay time before asserting the reset output. In automotive 12 V systems, load dump transients and cranking dips can cause temporary undervoltage conditions lasting 10 ms to 100 ms, and the programmable delay prevents these from triggering unnecessary ECU resets while still catching sustained fault conditions.
Why is TPS38A010122DSKRQ1 specified for ADAS domain controller power monitoring rather than a general-purpose supervisor?
TPS38A010122DSKRQ1 carries AEC-Q100 automotive qualification, ensuring device performance across the -40°C to +125°C temperature range required in under-hood ADAS installations. Its dual-channel design monitors 2 supply rails simultaneously in a 10-pin SON package, and the 65 V input range handles automotive load dump conditions without clamping, making it more robust than commercial-grade supervisors not rated for automotive transient environments.
