Table 8-7 STATUS Register Field Descriptions
BitFieldTypeResetDescription
7TSDR0Thermal shutdown status bit.
0: Normal operation.
1: Thermal shutdown tripped. This flag is reset after readout.
6

CRC_PASS

R1OTP test status bit.
0: OTP test failed. This bit is reserved for Test Engineers in TI.
1: Normal operation. This flag is reset after readout.
5VOUT_STARTR1Vout status bit.
0: Vout < 0.8V.
1: Vout > 0.8V.

This flag is reset after readout.

4OPMODER1Device mode of operation status bit.
0: Device operates in bypass mode.
1: Device operates in boost mode.
3ILIMPTR0Current limit status bit (bypass mode).
0: Normal operation.
1: Indicates that the bypass FET current limit has triggered. This flag is reset after readout.
2ILIMBSTR0Current limit status bit (dc/dc boost mode).
0: Normal operation.
1: Indicates that the average input current limit has triggered for 4ms in dc/dc boost mode. This flag is reset after readout.
1FL_LDR0Current limit status bit (dc/dc boost mode).
0: Normal operation.
1: Indicates that the average input current limit has triggered in dc/dc boost mode. This flag is reset after readout.
0PGOODR1Power Good status bit.
0: Indicates the output voltage is out of regulation.
1: Indicates the output voltage is within its nominal range. This bit is set to 1 if the converter operates in auto bypass mode.
