Product Overview
ADUM3223ARZ-RL7 is the reel-packed A-grade orderable of the ADuM3223 isolated half-bridge gate driver. It retains the family’s 4 A peak gate-drive capability, 1 MHz switching-frequency support and tightly matched isolated channels.
The electrical selection point remains the A-grade low secondary-UVLO threshold, while the -RL7 suffix identifies the reel supply form. It is therefore important to preserve both the A grade and the carrier suffix when a production BOM specifies this exact order code.

Production and Drive-Supply Considerations
A-grade UVLO permits use with lower gate-drive supply voltages than the B- and C-grade variants. The chosen rail must still satisfy the external transistor’s required gate voltage over temperature and load.
The -RL7 order code is a procurement distinction. Replacing it with a non-reel orderable may be electrically acceptable but can break feeder, AVL or material-control requirements.
