| Case | 20-VFQFN Exposed Pad |
The 2.25V to 3.6V supply range lets it run from a 2.5V or 3.3V rail without a dedicated LDO — the Enable/Disable pin gates the outputs for power sequencing or test modes. Housed in a 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height), the centre pad must be soldered to a ground plane for thermal and electrical reference.
Volume pricing determines BOM cost for production runs.
Immediate availability is critical to avoid production delays.
Design engineers need to verify fit with design requirements.
Finding a drop-in replacement avoids redesign costs.
Long lead times can impact project scheduling.
Accurate pinout is needed for PCB layout.
