Protection Systems

micro flux includes a number of configurable and absolute hardware and software protection systems configurable software protections can be used to fine tune the desired behaviour of the unit, while absolute software and hardware protections ensure safe and reliable operation the configurable warning system can identify issues before they result in shutdowns or failures true 113,151

of the target voltage the channel will turn off then reinitialise itself software protection each channel has a configurable under voltage deviation threshold each channel can optionally turn off when this threshold is passed there will be a warning flag set in telemetry when 75% of the limit is reached the unit will also send a warning and an error debug message there is a 15% hysteresis channel overvoltage protection software protection each channel has a configurable overvoltage deviation threshold each channel can optionally turn off when this threshold is passed there will be a warning flag set in telemetry when 75% of the limit is reached the unit will also send a warning and an error debug message there is a 15% hysteresis channel overtemperature protection hardware protection each channel includes an absolute overtemperature protection implemented in hardware that will shutdown the switching ic if the junction temperature reaches 175 °c \[347 °f] and will latch the channel off until the junction temperature decreases below 160 °c \[320 °f] software protection each channel has an absolute temperature limit of 160 °c \[320 °f] when this limit is reached the channel will be turned off in software and must be turned on by user intervention there is a 5 °c \[9 °f] hysteresis each channel has an optional configurable temperature limit each channel can be configured to turn off at the overtemperature limit there will be a warning flag set in telemetry when 80% of the limit is reached the unit will also send a warning and an error debug message there is a 5 °c \[9 °f] hysteresis channel undercurrent warning software warning there is a configurable under current limit, setting this limit to below 0 5a will disable the warning when enabled, this will set a warning flag in telemetry and send a debug message when the channel output current is below the threshold this can indicate a fault downstream from the output channel overcurrent protection hardware protection each channel implements a cycle by cycle current limit that prevents excessive current being drawn through the channel by terminating the switching period early this will result in the output voltage decreasing below the target voltage if the output drops below half of the target voltage the channel will turn off then reinitialise itself software protection each channel has a configurable current limit and can be configured to turn off at the current limit or do nothing there will be a warning flag set in telemetry when 90% of the limit is reached the unit will also send a warning and an error debug message there is a 0 5 amp hysteresis bus undervoltage protection software protection there is a configurable bus under voltage threshold and response when the limit is reached the device can be configured to turn off all non priority channels, turn all channels off, or do nothing there is a configurable timeout value, the bus voltage must be below the threshold for the configured timeout value before the under voltage response will act this timeout will prevent short transients causing the response to trigger, but the battery voltage dropping below a soc threshold will still cause it there will be a warning flag set in telemetry when within 2v of the limit the unit will also send a warning and an error debug message there is a 1v hysteresis bus overvoltage protection software protection there is a configurable bus overvoltage threshold and response when the limit is reached the device can be configured to turn off all non priority channels, turn all channels off, or do nothing there will be a warning flag set in telemetry when within 2v of the limit the unit will also send a warning and an error debug message there is a 1v hysteresis bus overcurrent protection software protection there is a configurable bus overcurrent limit and response when the limit is reached the device can be configured to turn off all non priority channels, turn all channels off, or do nothing there will be a warning flag set in telemetry when within 3a of the limit the unit will also send a warning and an error debug message there is a 0 5a hysteresis bus overtemperature protection software protection there is an absolute bus temperature limit of 160 °c \[320 °f] when this limit is reached all channels will be turned off there is a 5 °c \[9 °f] hysteresis there is a configurable bus overtemperature limit and response the device can be configured to turn off all non priority channels, all channels, or do nothing when this limit is reached there will be a warning flag set in telemetry when 80% of the limit is reached the unit will also send a warning and an error debug message there is a 5 °c \[9 °f] hysteresis mcu overtemperature protection software protection there is an absolute mcu temperature limit of 120 °c \[248 °f] when this limit is reached all channels will be turned off there is a 5 °c \[9 °f] hysteresis there is a configurable mcu overtemperature limit and response the device can be configured to turn off all non priority channels, all channels, or do nothing when this limit is reached there will be a warning flag set in telemetry when 80% of the limit is reached the unit will also send a warning and an error debug message there is a 5 °c \[9 °f] hysteresis
