Features
- include pulse-by-pulse current limiting, and a low 5-µA quiescent current during shutdown. The UCC39422 incorporates programmable power-on reset circuitry and an uncommitted comparator for low voltage detection. The available packages are 20-pin TSSOP or 20-pin N for the UCC39422, and 16-pin TSSOP or 16-pin N for the UCC39421.
