7-3 | ILIM2_VTH | R/W | 01001b |
ILIM2 Threshold 5 bits, percentage of IDPM in 0x0F/0EH. Measure current between ACP and ACN. Trigger when the current is above this threshold: 00001b - 11001b: 110% - 230%, step 5% 11010b - 11110b: 250% - 450%, step 50% 11111b: Out of Range (Ignored) Default 150%, or 01001 |
2-1 | ICRIT_DEG | R/W | 01b |
ICRIT Deglitch time ICRIT is set to be 110% of ILIM2. Typical ICRIT deglitch time to trigger PROCHOT. 00b: 15 µs 01b: 100 µs <default at POR> 10b: 400 µs (max 500 us) 11b: 800 µs (max 1 ms) |

---|---|---|---|---|
7-6 | VSYS_VTH | R/W | 01b |
VSYS Threshold Measure on VSYS with fixed 20-µs deglitch time. Trigger when SYS pin voltage is below the threshold. 00b: 5.75 V (2-4 s) or 2.85 V (1 s) 01b: 6 V (2-4 s) or 3.1 V (1 s) <default at POR> 10b: 6.25 V (2-4 s) or 3.35 V (1 s) 11b: 6.5 V (2-4 s) or 3.6 V (1 s) |
5 | EN_PROCHOT
_EXT |
R/W | 0b |
PROCHOT Pulse Extension Enable When pulse extension is enabled, keep the PROCHOT pin voltage LOW until host writes 0x36[2] = 0. 0b: Disable pulse extension <default at POR> |
4-3 | PROCHOT
_WIDTH |
R/W | 10b |
PROCHOT Pulse Width Minimum PROCHOT pulse width when REG0x36[5] = 0 00b: 100 µs 01b: 1 ms 10b: 10 ms <default at POR> 11b: 5 ms |
2 | PROCHOT
_CLEAR |
R/W | 1b |
PROCHOT Pulse Clear Clear PROCHOT pulse when 0x36[5] = 1. 0b: Clear PROCHOT pulse and drive PROCHOT pin HIGH. 1b: Idle <default at POR> |
1 | INOM_DEG | R/W | 0b |
INOM Deglitch Time INOM is always 10% above IDPM in 0x0F/0EH. Measure current between ACP and ACN. Trigger when the current is above this threshold. 0b: 1 ms (must be max) <default at POR> 1b: 50 ms (max 60 ms) |
