65-V rail watchdog with 0.8 V threshold
The TPS3760A012DYYR is a 65-V overvoltage or undervoltage monitor from Texas Instruments, designed to keep a single supply rail in check. It asserts a reset output (active low, open drain) when the monitored voltage drops below 0.8 V or exceeds the programmed threshold — the 65-V absolute maximum lets it sit directly on a high-voltage bus without a pre-regulator divider eating into the accuracy budget.
100 µs reset timeout — fast enough for core sequencing
Reset timeout is 100 µs maximum, which means the part clears the reset flag within 100 µs after the supply returns above threshold. That is fast enough to sequence a DSP or FPGA core rail without holding the system in reset longer than the downstream device's power-good window.
The 14-SOT-23-THIN package keeps the footprint small — 0.65 mm pitch, about 3 mm × 3 mm — so it fits on tight mixed-signal boards without crowding the high-voltage creepage zone. Lifecycle status is Active. ROHS3 compliant. Sourced per RFQ against BOM quantity; no stock-holding claim.
