Functional Description
Switching of the TS51231 transmitter driver is controlled by the wireless transmitter controller via the HSON pin. When the HSON
pin is high, the high-side FET is switched on and the low-side FET is switched off. When the HSON pin is low, the high-side FET is
switched off and the low-side FET is switched on.
