81 / 84 page ![]() Data Sheet ADP1053 Rev. A | Page 81 of 84 Table 134. Register 0xFEC4—Flag Register 5 and Register 0xFEC9—Latched Flag Register 5 (1 = Fault, 0 = Normal Operation) Bits Bit Name R/W Description Register Action [7:4] Reserved R Reserved. 3 OTW2 R Temperature of Zone 2 is above the OTW2 threshold. 0xFE8A Programmable 2 OTW1 R Temperature of Zone 1 is above the OTW1 threshold. 0xFE8A Programmable 1 REVERSE_B R CS2_B reverse current falls below the CS2_B reverse current threshold. 0xFE85 Programmable 0 REVERSE_A R CS2_A reverse current falls below the CS2_A reverse current threshold. 0xFE84 Programmable Register 0xFECA and Register 0xFECB record the first flag ID for Channel A and Channel B, respectively. The first flag ID represents the first flag that triggers a response and requires a soft start after the fault is resolved. The Channel A first flag ID register (Register 0xFECA) records the first flag ID of the fault that shut down Channel A; the Channel B first flag ID register (Register 0xFECB) records the first flag ID of the fault that shut down Channel B. For more information, see the First Flag ID Recording section. Table 135. Register 0xFECA and Register 0xFECB—Channel A and Channel B First Flag ID Bits Bit Name R/W Description [7:4] Previous first flag ID R These bits return the flag fault ID of the flag that caused the previous shutdown of Channel A or Channel B. This previous shutdown occurred before the shutdown caused by the fault identified in Bits[3:0].
