65-V window supervisor with dual threshold monitoring
The Texas Instruments TPS37F010122DSKR is a voltage detector in the TPS37 family, specifically a 65-V window supervisor that monitors two independent voltage rails against 0.8V thresholds each. This dual-channel window supervisor is designed for systems where overvoltage and undervoltage detection on separate supply lines must be consolidated into a single supervisory IC, reducing BOM count and board area.
Industrial temperature range and reset behavior
Operating from -40°C to 125°C junction temperature, the device suits industrial and automotive-adjacent environments where the ambient temperature under load can exceed 85°C, such as base-station power supplies or motor-drive control boards. The reset output is configurable as active high or active low with open-drain outputs, giving the system designer flexibility to interface with both positive-logic enable pins and active-low reset inputs on the downstream processor or FPGA. A maximum reset timeout of 100 µs ensures the system recovers quickly after the monitored voltage returns to the valid window, minimizing downtime in fault-recovery sequences.
Surface-mount assembly with the exposed pad requires a solder stencil aperture covering at least 50% of the pad area to ensure void-free attachment and consistent thermal resistance.
