ZHCSME0B December 2020 – November 2022 TPS7A43
PRODUCTION DATA
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.
| SET VMVSEL1 | SET VMVSEL2 | MID_OUT |
|---|---|---|
| VMVSEL1 ≤ VMVSEL1(LOW) | VMVSEL2 ≤ VMVSEL2(LOW) | 15 V |
| VMVSEL1 ≤ VMVSEL1(LOW) | VMVSEL2 ≥ VMVSEL2(HIGH) | 12 V |
| VMVSEL1 ≥ VMVSEL1(HIGH) | VMVSEL2 ≤ VMVSEL2(LOW) | 10 V |
| VMVSEL1 ≥ VMVSEL1(HIGH) | VMVSEL2 ≥ VMVSEL2(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 + VDO(MID_OUT). Additionally, to maintain regulation on the OUT pin, the MID_OUT voltage must be set ≥ VOUT(nom) + VDO(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 VMID_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.
