Key Features
- 0.5% threshold accuracy across four independently configurable voltage supervisor channels for precise multi-rail power monitoring
- H-grade temperature rating enables operation over the full -40°C to +125°C industrial and automotive range
- QFN-20 (R-PQCC-N20) package provides a 4 mm x 4 mm footprint with adjustable thresholds, minimizing BOM count for quad-rail supervision
Applications
The LTC2963HUDC-1#PBF is designed for multi-rail power sequencing in FPGAs, ASICs, and complex SoC platforms where all four supply rails must reach valid voltage levels within ±0.5% tolerance before releasing the system reset. It is also used in industrial motor drives and automotive ECUs requiring precise under-voltage lockout on 1.8 V, 2.5 V, 3.3 V, and 5 V rails simultaneously, with each channel independently configurable via external resistor dividers.

Frequently Asked Questions
How accurate are LTC2963HUDC-1#PBF's threshold comparators and how many rails can it monitor?
LTC2963HUDC-1#PBF achieves 0.5% threshold accuracy across all 4 independently configurable voltage supervisor channels, allowing it to monitor four separate power rails such as 1.8 V, 2.5 V, 3.3 V, and 5 V simultaneously with minimal false-trip risk.
Which FPGA or SoC power sequencing scenarios require LTC2963HUDC-1's quad configurable supervisor?
Complex FPGAs like Xilinx Ultrascale+ or Intel Agilex require 3 to 5 power rails to sequence within microsecond windows; LTC2963HUDC-1#PBF monitors all 4 rails with 0.5% accuracy and holds the FPGA in reset until every rail is within spec, preventing core corruption during power-up.
What temperature range does the H-grade LTC2963HUDC-1#PBF support for industrial applications?
The H-grade designation qualifies LTC2963HUDC-1#PBF for operation from -40°C to +125°C, making it suitable for automotive ECUs, industrial motor controllers, and outdoor power electronics exposed to extreme ambient temperature swings.
Is LTC2963HUDC-1#PBF available in a lead-free package and what is its footprint?
Yes, the #PBF suffix confirms RoHS-compliant lead-free finish (JESD-609 code e3) and the QFN-20 package (R-PQCC-N20) measures approximately 4 mm x 4 mm, reducing PCB area by up to 60% compared to equivalent SOIC-20 supervisory ICs.
