OPERATION
1 = FET On, 0 = FET Off
Reports the State of the GPIO1 Pin; 1 = GPIO1 High, 0 = GPIO1 Low
Reports the State of the GPIO2 Pin; 1 = GPIO2 High, 0 = GPIO2 Low
Indicates if the LTC4215 is Enabled when EN is Low; 1 = EN Pin Low, 0 = EN Pin High
Indicates Power is Bad when FB is Low; 1 = FB Low, 0 = FB High
Reports the State of the GPIO3 Pin; 1 = GPIO3 High, 0 = GPIO3 Low
Indicates Input Undervoltage when UV is Low; 1 = UV Low, 0 = UV High
Indicates V
OPERATION
Sets the State of the GPIO3 Pin; 1 = GPIO3 Pulled Low (Default), 0 = GPIO3 High Impedance
Sets the State of the GPIO2 Pin; 1 = GPIO2 Pulled Low, 0 = GPIO2 High Impedance (Default)
Indicates Potential FET Short was Detected when Measured Current Sense Volage Exceeded 1mV While FET was Off;
1 = FET is Shorted, 0 = FET is Good
Indicates That the LTC4215 was Enabled or Disabled when EN Changed State; 1 = EN Changed State, 0 = EN Unchanged
Indicates Power was Bad when FB when Low; 1 = FB was Low, 0 = FB was High
Indicates Overcurrent Fault Occured; 1 = Overcurrent Fault Occured, 0 = Not Overcurrent Faults
Indicates Input Undervoltage Fault Occured when UV went Low; 1 = UV was Low, 0 = UV was High
Indicates Input Overvoltage Fault Occured when OV went High; 1 = OV was High, 0 = OV was Low
DD
or OV Input Overvoltage when OV is High; 1 = OV High, 0 = OV Low
