The BQ24810 device supports the hybrid power boost mode to boost battery voltage to adapter level and supplement adapter power when system power demand is temporarily higher than adapter maximum level. Ultra fast 100 μs response time (requires REG0x37[4:3] = 10b) keeps the adapter from crashing. After device powers up, the REG0x37[2] is 0 to disable hybrid power boost mode. To enable hybrid power boost mode, host writes 1 to REG0x37[2]. The BST_STAT pin and REG0x37[1] indicate if the device is in hybrid power boost mode when 0x37[11] = 1.
To support hybrid power boost mode, input current must be set higher than 1024 mA for 10-mΩ input current sensing resistor including 1024mA. There is internal minimum clamp 960mA internal to prevent charger enter turbo boost mode if IINDPM is programmed 960mA or lower. The threshold to enter hybrid power boost mode (FDPM_RISE in REG0x37[5]) is set as percentage to the input current limit. When peak power is not enabled, the input current limit is always ILIM1, set in REG0x3F(). For discussion of hybrid boost behavior when peak power is enabled, refer to Section 6.3.6. When input current is higher than FDPM_RISE of input current limit, the BQ24810 converter changes from buck charging converter to hybrid power boost converter. During hybrid power boost mode the adapter current is regulated at input current limit level so that adapter will not crash. If the watchdog timer is enabled (REG0x12[14:13]) and it expires, it will halt the hybrid boost mode converter. Writing to REG0x12[14:13], REG0x14 or REG0x15 will restart the watchdog timer and allow hybrid boost mode to be reentered.
One of the following conditions stops on-going hybrid power boost mode:
