|---|---|---|
| [15] | EN_3L | Enable three level input current regulation
0: Disable three-level adapter current limit. (default at POR) 1: Enable three-level adapter current limit. |
| [14:11] | Peak Adapter Current Limit (ILIM2_VTH) |
ILIM2 threshold as percentage of DPM in
REG0x3F(). At 250% setting, when IDPM is over
3.648A, clamp ILIM2 to 230% of IDPM. The current is measured on the RAC between ACP and ACN. ICRIT is set as 110% of ILIM2. 0001 - 1001: 110% - 150%, step 5% 1001: 150%, 1010: 160%, 1011: 170%, 1100: 180%, 1101: 200%, 1110: 220%; 1111: 250% Default 150% (1001) |
| [10:9] | ICRIT Deglitch Time (ICRIT_DEG) |
Typical ICRIT deglitch time. 00: 10 μs 01: 100 μs (default at POR) 10: 400 μs 11: 800 μs |
| [8] | Reserved | 0 - Reserved |
| [7:6] | Battery Voltage Threshold (VBATT_VTH) |
Battery voltage threshold to trigger
PROCHOT. Measure on SRN with fixed 20-μs deglitch time. Trigger when SRN voltage is below the threshold. If REG0x15() is programmed below VBATT threshold, it is recommended to not enable VBATT in PROCHOT profile. 00: 5.75 V 01: 6.00 V (default at POR) 10: 6.25 V 11: 6.50 V |
| [5] | PROCHOT Pulse
Extension Enable (EN_PROCHOT_EXT) |
When pulse extension is enabled, keep
PROCHOT pin voltage low until
host write 0x3C[2] = 0. 0: Disable pulse extension (default at POR) 1: Enable pulse extension |
| [4:3] | PROCHOT Pulse Width (PROCHOT_WIDTH[1:0]) |
Minimum PROCHOT pulse
width when REG0x3C[5]=0 00: 100 μs 01: 1 ms 10: 10 ms (default at POR) 11: 5 ms |
| [2] | PROCHOT Pulse Clear (PROCHOT_CLEAR) |
Clear PROCHOT pulse
when (0x3C[5] = 1). 0: Clear PROCHOT pulse and drive PROCHOT pin HIGH 1: Idle (default at POR) |
| [1] | INOM Deglitch Time (INOM_DEG) |
Maximum INOM deglitch time.
INOM threshold is 110% of DPM in REG0x3F().
Measure current between ACP and ACN. Trigger when
the current is above this threshold. 0: 1 ms (max) (default at POR) 1: 15 ms (max) |
| [0] | INOM Threshold (INOM_VTH) |
INOM current threshold as percentage of DPM
in REG0x3F(). 0: 110% (default at POR) 1: 106% |
