46 / 94 page  9.6.1.5 ProchotOption0 Register (I2C address = 37/36h) [reset = 4A65h] Figure 9-16. ProchotOption0 Register (I2C address = 37/36h) [reset = 4A65h] 7-3 2-1 0 ILIM2_VTH ICRIT_DEG PROCHOT_ VDPM_80_90 R/W R/W R/W 7-4 3-2 1 0 VSYS_TH1 VSYS_TH2 INOM_DEG LOWER_ PROCHOT _VDPM R/W R/W R/W R/W LEGEND: R/W = Read/Write; R = Read only; -n = value after reset Table 9-13. ProchotOption0 Register (I2C address = 37h) Field Descriptions I2C 37h FIELD TYPE RESET DESCRIPTION 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% ofILIM2. Typical ICRIT deglitch time to trigger PROCHOT. 00b: 15 µs 01b: 120 µs <default at POR> 10b: 500 µs 11b: 1 ms 0 PROCHOT_ VDPM_80_90 R/W 0b Lower threshold of the PROCHOT_VDPM comparator When REG0x36[0]=1, the threshold of the PROCHOT_VDPM comparator is determined by this bit setting. 0b: 80% of VinDPM threshold <default at POR>. 1b: 90% of VinDPM threshold Table 9-14. ProchotOption0 Register (I2C address = 36h) Field Descriptions I2C 36h FIELD TYPE RESET DESCRIPTION 7-4 VSYS_TH1 R/W 0110b VSYS Threshold to trigger discharging VBUS in VAP mode. Measure on VSYS with fixed 5-µs deglitch time. Trigger when SYS pin voltage is below the thresholds. 2S - 4S battery 0000b - 1111b: 5.9 V - 7.4V with 0.1 V step size. 1S battery 0000b - 0111b: 3.1 V - 3.8 V with 0.1 V step size. 1000b - 1111b: 3.1 V - 3.8 V with 0.1 V step size.
