I am analysing a pulse transformer which is required to transfer below communication protocol pulse from primary to the secondary side. The pulse duration is 32 μs and off time available to reset the core is just 7 μs. Calculation shows that -22.85 V are required to reset the core within 7 μs.

Is there any way to reset a core quickly without having ground / reference terminal pulled towards negative voltage ? because when -22.85 V is applied across TTL logic pins like microcontroller,they will get damaged.
