| BIT | BIT NAME | DESCRIPTION |
|---|---|---|
| [15] | Discharge Current Regulation Enable (EN_IDCHG_REG) | Battery discharge current regulation enable. 0: Disable discharge current regulation (default at POR) 1: Enable discharge current regulation |
| [14] | FDPM_FALL_DEG | Turbo boost mode exit deglitch time when IIN falls below FDPM_FALL threshold but still
>0.75A(IINDPM>2A) or >0.38A(IINDPM<2A). 0: 320us. (default at POR) 1: 640us. |
| [13] | ACDRV Disable (ACDRV_OFF) | Force ACFET/RBFET to turn off, even with good adapter present. 0: ACFET/RBFET control based on "System Power Selection". (default at POR) 1: Turn off ACFET/RBFET. |
| [12] | ACOK Deglitch Time for Primary Input (ACOK_DEG ) | Adjust ACOK rising edge deglitch time. After POR, the first time adapter plugs in, deglitch time is always 150 ms if this register has not been written by the host. Starting from the 2nd time adapter plugs in, the deglitch time follows the bit setting. 0: ACOK rising edge deglitch time 150ms 1: ACOK rising edge deglitch time 1.3 sec (default at POR) |
| [11] | Adapter Present Indicator (ACOK_STAT ) | Input present indication bit. This bit is set to 1 when ACOK pin goes HIGH. Refer to for conditions to transition ACOK. 0: AC adapter is not present 1: AC adapter is present |
| [10] | ACOC Enable (EN_ACOC) | ACOC protection threshold by monitoring ACP_ACN voltage. 0: Disable ACOC (default at POR) 1: Enable ACOC |
| [9] | ACOC Limit (ACOC_VTH) | ACOC protection threshold by monitoring ACP_ACN voltage. 0: 125% of ILIM2 1: 200% of ILIM2 (default at POR) |
| [8] | PKPWR_ENCHRG | Allow battery charging during peak power TMAX cycle. 0: Battery charging is NOT allowed during TMAX. The adapter only supports system load. This reduces the chance of overloading the adapter. (default at POR) 1: Battery charging is allowed during TMAX. The adapter current capability of ILIM1 and ILIM2 is fully utilized. |
| [7] | HSFET VDS Threshold (IFAULT_HI) | MOSFET/inductor short protection by monitoring ACN to PHASE voltage 0: Disable (default at POR) 1: 750 mV |
| [6] | LSFET VDS Threshold (IFAULT_LO) | MOSFET/inductor short protection by monitoring PHASE to GND voltage (LSFET drain-source voltage.) Also provides cycle-by-cycle current limit protection during hybrid boost and battery only boost functions. 0: Disable 1: 250 mV (default at POR) |
| [5:3] | Fast DPM Deglitch Time (FDPM_DEG) | Response time from system current exceeding Fast DPM Threshold to battery discharge in boost
mode. 000: Response time 10 μs 001: Response time 20 μs 010: Response time 50 μs 011: Response time 100 μs (default at POR) 100: Response time 185 μs 101: Response time 380 μs 110: Response time 750 μs 111: Response time 1.5 ms |
| [2] | Hybrid Power Boost Mode Enable(EN_HYBRID_BOOST) | Hybrid power boost mode enable bit. When
BATPRES goes from LOW to HIGH (battery removal), this bit will be reset to zero to disable boost mode. When the charger exits hybrid power boost due to smaller load or fault, this enable bit doesn't automatically go to zero. 0: Disable hybrid power boost mode (default at POR) 1: Enable hybrid power boost mode |
| [1] | Boost Mode Indication (BOOST_STAT) | Active-high boost mode indicator. This bit is read only. 0: Charger is not in hybrid power boost mode or battery only boost mode (default at POR) 1: Charger is in hybrid power boost mode or battery only boost mode(Note that the BST_STAT pin is active-low and is low when the BOOST_STAT register bit is set to 1.) |
| [0] | FAST_CHG_TURBO_TRANS | Minimize the converter shut off time when transfer from charign direction to reverse turbo
boost operation 0: Disable (default at POR) 1: Enable |
