Use the Mode register to reset the MAX14820 and manage the 3.3V LDO. The Mode register has bits that represent
the current status of fault conditions. When writing to the Mode register, the contents of the fault indication bits
(bits 2 to 5) do not change.
BIT
NAME
DESCRIPTION
D7
RST
Register Reset. Set RST to 1 to reset all registers to their default power-up state. Then
set RST to 0 for normal operation.
The Status register is cleared and IRQ deasserts (if asserted) when RST = 1. Interrupts
are not generated while RST = 1.
D6
WuIntEn
Wake-Up Interrupt Enable. Set WuIntEn to 1 to enable wake-up interrupt generation.
When WuIntEn is set, the WuInt bit in the Status register is set and IRQ asserts when
a valid wake-up condition is detected. The C/Q driver must be enabled for wake-up
detection. The state of WuIntEn does not affect the WU output. See the Wake-Up
Detection section for more information.
D5
DoFault
DO Fault Status. The DoFault bit is set when a short circuit or voltage fault occurs at
the DO driver output (see the DO Fault Detection section for more information). The
DoFault and DoFaultInt bits are both set when a fault occurs on DO. DoFault is cleared
when the fault is removed.
D4
C/QFault
C/Q Fault Status. The C/QFault bit is set when a short circuit or voltage fault occurs at
the C/Q driver output (see the C/Q Fault Detection section for more information). The
C/QFault and C/QFaultInt bits are both set when a fault occurs on C/Q. C/QFault is
cleared when the fault is removed.
D3
UV24
VCC Undervoltage Condition. Both the UV24 and the UV24Int bits are set when VCC
falls below VCCUVLO. UV24 is cleared when VCC rises above the VCC threshold. V5
must be present for VCC undervoltage monitoring.
D2
OTemp
Temperature Warning. The OTemp bit is set when a high-temperature condition
occurs on the devices. Both the OTempInt interrupt in the Status register and the
OTemp bit are set when the junction temperature of the die rises to above +115NC
(typ). The OTemp bit is cleared when the junction temperature falls below +95NC (typ).
D1
UV33En
LDO33 UV Enable. Set the UV33En bit to 1 to assert the UV output when LDO33
voltage falls below the 2.4V (typ) undervoltage lockout threshold. The UV33En bit does
not affect the UV33Int bit in the Status register; IRQ asserts when VLDO33 falls below
VLDO33UVLO regardless of the state of UV33En.
D0
LDO33Dis
LDO33 Enable/Disable. Set LDO33Dis to 1 to disable the 3.3V linear regulator (LDO33).
