8.1.1 MID_OUT Voltage Setting

The MID_OUT voltage has three different output voltage levels (10 V, 12 V, and 15 V), as listed in Table 8-1, depending on the MVSEL1 and MVSEL2 pin voltage settings.

Table 8-1 MID_OUT Voltage Setting

SET V_MVSEL1	SET V_MVSEL2	MID_OUT
V_MVSEL1 ≤ V_MVSEL1(LOW)	V_MVSEL2 ≤ V_MVSEL2(LOW)	15 V
V_MVSEL1 ≤ V_MVSEL1(LOW)	V_MVSEL2 ≥ V_MVSEL2(HIGH)	12 V
V_MVSEL1 ≥ V_MVSEL1(HIGH)	V_MVSEL2 ≤ V_MVSEL2(LOW)	10 V
V_MVSEL1 ≥ V_MVSEL1(HIGH)	V_MVSEL2 ≥ V_MVSEL2(HIGH)	12 V

For adjustable voltage options of the TPS7A43, and to maintain voltage regulation on the MID_OUT and OUT pins, the input voltage must be kept ≥ MID_OUT + V_{DO(MID_OUT)}. Additionally, to maintain regulation on the OUT pin, the MID_OUT voltage must be set ≥ V_OUT(nom) + V_DO(OUT).

Set the MVSEL1 and MVSEL2 voltages before enabling the device to set the MID_OUT voltage level; however, the MID_OUT voltage setting can be changed to a different level after the device had powered up. Do not allow these pins to float, instead tie them both to GND if not used to set V_{MID_OUT}. When the device is powered while either of these pins are floating, the MID_OUT voltage is not set properly and might switch levels and cause damage to the device.
