If I2T is enabled (I2T_EN_CH2 = 1) and OL_ON_EN_CH2 = 1, the lower K_SNS2 will be applied to the I2T algorithm which will provide different I2T trip thresholds and can cause the channel to turn off at a lower I2T threshold. The device can only enter this mode if there are no existing faults on the channel and the output current is below I_{ENTRY_OL_ON}. 0h = KSNS1 ratio and RON = RON 1h = KSNS2 ratio and RON = RON_OL
8-7	OL_SVBB_BLANK_CH2	R/W	0h	These bits determine the blanking time for open load or short to VBB faults in the OFF state for channel 2 0h = Blanking time is 0.4ms 1h = Blanking time is 1.0ms 2h = Blanking time is 2.0ms 3h = Blanking time is 4.0ms
6-5	OL_PU_STR_CH2	R/W	0h	These bits determine the pull-up current (I_pu) at the VOUT1 for the off-state open load detection circuitry. 0h = I_pu is 26.5µA 1h = I_pu is 60µA 2h = I_pu is 127µA 3h = I_pu is 260µA
4-3	OL_SVBB_EN_CH2	R/W	0h	These bits are used to enable open load and short to supply detection in OFF state. Setting the bits to 10 turns on the pull up to see if there is an open load or short to supply in the off state with an output comparator. If OL_OFF_CH2 = 1, then either a short to supply or an open load fault exists. After this, the bits can be set to 01 to turn on a pull down to distinguish a short to supply from an open load in the off state. If there is a short to supply then SHRT_VBB_CH2 = 1 and if not then SHRT_VBB_CH2 = 0 and an open load exists. The above sequence is detailed in the 'Detection With Switch Disabled' section 0h = Disabled 1h = Turns-on an output pulldown to differentiate Short to supply from open load. 2h = Turns on a pull-up from VBB supply to output to detect if either an open load or short-to-battery exists. 3h = Output comparator enabled, use external switches and pull-up/pull-down to detect open load or short-to-supply.
2	LATCH_CH2	R/W	0h	This bit determines if channel 2 should auto-retry or latch off after an overcurrent or thermal shutdown event has occurred. 0h = channel 2 will auto retry after tRETRY expires and THYS is reached 1h = channel 2 latches off until SW_STATE register is written to again
1-0	SLRT_CH2	R/W	2h	These bits determine the turn on and turn off slew rates for channel 2. 0h = 0.14V/µs 1h = 0.2V/µs 2h = 0.25V/µs 3h = 0.32V/µs

Bit	Field	Type	Reset	Description
15-14	TCLDN_CH2	R/W	0h	These bits set the cool down time (or time to retry) after an I2T shutdown for channel 2. Note: If setting 0x0 is used, the channel will remain off after an I2T shutdown with no retry. To retry in this setting, change the bits to 0.8s, 2.0s, or 4.0s options to allow the device to retry after an I2T shutdown. 0h = indefinite cooldown 1h = 0.8s 2h = 2.0s 3h = 4.0s
13-11	RESERVED	R/W	0h	Reserved
10-9	SWCL_DLY_TMR_CH2	R/W	0h	These bits set the timer at which channel 2 will shut down if the I_OUT current continuously exceeds the ISWCL level for the configured time. 0h = 0.2ms 1h = 0.4ms 2h = 1.0ms 3h = 2.0ms
8-7	ISWCL_CH2	R/W	0h	These bits set the delayed turn off current sense value (I_SWCL,700) for channel 2. Once the I_OUT current exceeds the I_SWCL,700 value, a timer starts and will turn off the channel if the current remains above the I_SWCL,700 threshold for a duration of SWCL_DLY_TMR_CH2. The threshold should be set below the current sense saturation value (I_{OUT_SAT} = K_SNS1 * I_{SNS_SAT}). The current threshold below assume R_SNS = 700Ω. To calculate the new I_SWCL,700 thresholds based on a different R_SNS value, the following equation can be used: I_SWCL,ADJ = I_SWCL,700 * (700 / R_SNS) 0h = 19.55A 1h = 17.6A 2h = 16.05A 3h = 13.3A
6-3	I2T_TRIP_CH2	R/W	0h	These bits set the I2T trip value for Channel 2. Note: For reference the equation for the I2T trip value is: I2T = (I_OUT2² - NOM_CUR_CH2²) * t The below values assume R_SNS = 700Ω. To calculate the new I2T trip values based on a different R_SNS value, the following equation can be used: I2T_ADJ = I2T₇₀₀ * (700 / R_SNS)² Note: The I2T_TRIP_CH2 value cannot be modified when the device is in the cool down time period. 0h = 8.8 A2s 1h = 13.1 A2s 2h = 26.3 A2s 3h = 39.4 A2s 4h = 52.5 A2s 5h = 65.6 A2s 6h = 78.8 A2s 7h = 91.9 A2s 8h = 109.4 A2s 9h = 126.9 A2s Ah = 144.4 A2s Bh = 166.3 A2s Ch = 192.5 A2s Dh = 218.8 A2s Eh = 262.5 A2s Fh = 350 A2s
2-0	NOM_CUR_CH2	R/W	0h	These bits set the nominal current value for channel 2 for the I2T function. If the I2T function is enabled for channel 2, above this value the device will enter the I2T accumulation mode. The nominal current values below assume R_SNS = 700Ω. To calculate the new I2T trip values based on a different R_SNS value, the following equation can be used: NOM_CUR_CH2_ADJ = NOM_CUR_CH2₇₀₀ * (700 / R_SNS) Note: The NOM_CUR_CH2 value cannot be modified when the device is in the cool down time period. 0h = 4.0A 1h = 5.0A 2h = 5.7A 3h = 6.5A 4h = 7.5A 5h = 9.0A 6h = 12.0A 7h = 15.0A
