We are running into an L99MC6 caution (lowest caution on page 12 of Doc ID 16523 Rev 1) where our +13.8V supply is bleeding back through relay coils to source outputs and elevating the 3.3V Vcc supply before the charge pump seems to ramp up). Workarounds?

Our circuit uses an L99MC6 6-ch driver in 3-ch bridged mode to drive 3 relays (Song Chuan p/n 301-1A-C-R1-U03-12VDC) with a common +12V rail connected to the relays. The relays are activated by a sink output. The circuit's 3.3V logic Vcc is temporari...
