BIT(S) SYMBOL OPERATION
B[14] Mfr_gpio_propagate_short_CMD_cycle 0: No action
1: Asserts low if commanded off then on before the output has sequenced off. Re-asserts high
120ms after sequence off.
b[13] Mfr_gpio_propagate_ton_max_fault 0: No action if a TON_MAX_FAULT fault is asserted
1: Associated output will be asserted low if a TON_MAX_FAULT fault is asserted
GPIO0 is associated with page 0 TON_MAX_FAULT faults
GPIO1 is associated with page 1 TON_MAX_FAULT faults
b[12] Mfr_gpio0_propagate_vout_uvuf,
Mfr_gpio1_propagate_vout_uvuf
Unfiltered VOUT_UV_FAULT_LIMIT comparator output
GPIO0 is associated with channel 0
GPIO1 is associated with channel 1
b[11] Mfr_gpio0_propagate_int_ot,
Mfr_gpio1_propagate_int_ot
0: No action if the MFR_OT_FAULT_LIMIT fault is asserted
1: Associated output will be asserted low if the MFR_OT_FAULT_LIMIT fault is asserted
b[10] Mfr_pwrgd1_en (Note 1) 0: No action if channel 1 POWER_GOOD is not true
1: Associated output will be asserted low if channel 1 POWER_GOOD is not true
If this bit is asserted, the GPIO_FAULT_RESPONSE must be ignore. If the GPIO_FAULT_
RESPONSE is not set to ignore, the part will latch off and never be able to start.
b[9] Mfr_pwrgd0_en (Note 1) 0: No action if channel 0 POWER_GOOD is not true
1: Associated output will be asserted low if channel 0 POWER_GOOD is not true
If this bit is asserted, the GPIO_FAULT_RESPONSE must be ignore. If the GPIO_FAULT_
RESPONSE is not set to ignore, the part will latch off and never be able to start.
b[8] Mfr_gpio0_propagate_ut,
Mfr_gpio1_propagate_ut
0: No action if the UT_FAULT_LIMIT fault is asserted
1: Associated output will be asserted low if the UT_FAULT_LIMIT fault is asserted
GPIO0 is associated with page 0 UT faults
GPIO1 is associated with page 1 UT faults
b[7] Mfr_gpio0_propagate_ot,
Mfr_gpio1_propagate_ot
0: No action if the OT_FAULT_LIMIT fault is asserted
1: Associated output will be asserted low if the OT_FAULT_LIMIT fault is asserted
GPIO0 is associated with page 0 OT faults
GPIO1 is associated with page 1 OT faults
b[6] Reserved
b[5] Reserved
b[4] Mfr_gpio0_propagate_input_ov,
Mfr_gpio1_propagate_input_ov
0: No action if the VIN_OV_FAULT_LIMIT fault is asserted
1: Associated output will be asserted low if the VIN_OV_FAULT_LIMIT fault is asserted
b[3] Reserved
b[2] Mfr_gpio0_propagate_iout_oc,
Mfr_gpio1_propagate_iout_oc
0: No action if the IOUT_OC_FAULT_LIMIT fault is asserted
1: Associated output will be asserted low if the IOUT_OC_FAULT_LIMIT fault is asserted
GPIO0 is associated with page 0 OC faults
GPIO1 is associated with page 1 OC faults
b[1] Mfr_gpio0_propagate_vout_uv,
Mfr_gpio1_propagate_vout_uv
0: No action if the VOUT_UV_FAULT_LIMIT fault is asserted
1: Associated output will be asserted low if the VOUT_UV_FAULT_LIMIT fault is asserted
GPIO0 is associated with page 0 UV faults
GPIO1 is associated with page 1 UV faults
b[0] Mfr_gpio0_propagate_vout_ov,
Mfr_gpio1_propagate_vout_ov
0: No action if the VOUT_OV_FAULT_LIMIT fault is asserted
1: Associated output will be asserted low if the VOUT_OV_FAULT_LIMIT fault is asserted
GPIO0 is associated with page 0 OV faults
GPIO1 is associated with page 1 OV faults
Note 1: The PWRGD status is designed as an indicator and not to be used for power supply sequencing.
