19 / 64 page  LTC2978 2978fa Summary COMMAND FUNCTION DESCRIPTION R/W DATA LENGTH (BITS) COMMAND BYTE VALUE NV MEMORY TYPE DEFAULT VALUE PAGED ? VOUT_UV_FAULT_LIMIT Undervoltage DC/DC converter fault limit setting. This limit is also used to determine if Ton_max_fault has been met and the unit is on. R/W 16 ‘h44 EEPROM ‘h1CCD Y VOUT_UV_FAULT_RESPONSE The VOUT_UV_FAULT_RESPONSE command instructs the device on what action to take in response to an undervoltage fault. R/W 8 ‘h45 EEPROM ‘h7F Y OT_FAULT_LIMIT Overtemperature fault limit setting. R/W 16 ‘h4F EEPROM ‘hEAA8 N OT_FAULT_RESPONSE The OT_FAULT_RESPONSE command instructs the device on what action to take in response to an overtemperature fault. R/W 8 ‘h50 EEPROM ‘hB8 N OT_WARN_LIMIT Overtemperature warning limit setting. R/W 16 ‘h51 EEPROM ‘hEA58 N UT_WARN_LIMIT Undertemperature warn limit setting. R/W 16 ‘h52 EEPROM ‘h8000 N UT_FAULT_LIMIT Undertemperature fault limit setting. R/W 16 ‘h53 EEPROM ‘hCD80 N UT_FAULT_RESPONSE The UT_FAULT_RESPONSE command instructs the device on what action to take in response to an undertemperature fault. R/W 8 ‘h54 EEPROM ‘hB8 N VIN_OV_FAULT_LIMIT Input supply overvoltage fault limit setting. R/W 16 ‘h55 EEPROM ‘hD3C0 N VIN_OV_FAULT_RESPONSE The VIN_OV_FAULT_RESPONSE command instructs the device on what action to take in response to an input overvoltage fault. R/W 8 ‘h56 EEPROM ‘h80 N VIN_OV_WARN_LIMIT Overvoltage input supply warning limit setting. R/W 16 ‘h57 EEPROM ‘hD380 N VIN_UV_WARN_LIMIT Undervoltage input supply warning limit setting. R/W 16 ‘h58 EEPROM ‘h8000 N VIN_UV_FAULT_LIMIT Undervoltage input supply fault limit setting. R/W 16 ‘h59 EEPROM ‘h8000 N VIN_UV_FAULT_RESPONSE The VIN_UV_FAULT_RESPONSE command instructs the device on what action to take in response to an input undervoltage fault. R/W 8 ‘h5A EEPROM ‘h00 N POWER_GOOD_ON Output voltage at or above which a power good should be asserted. R/W 16 ‘h5E EEPROM ‘h1EB8 Y POWER_GOOD_OFF Output voltage at or below which a power good should be deasserted. R/W 16 ‘h5F EEPROM ‘h1E14 Y TON_DELAY Time, in ms, from CONTROL and/or Operation on to VOUT_EN on. R/W 16 ‘h60 EEPROM ‘hBA00 Y TON_RISE Time, in ms, from when the output starts to rise until the LTC2978 optionally soft- connects its voltage-buffered current DAC and begins to servo the output voltage to the desired value. R/W 16 ‘h61 EEPROM ‘hD280 Y TON_MAX_FAULT_LIMIT Maximum time, in ms, from VOUT_EN on assertion that an UV condition will be tolerated before a TON_MAX_FAULT condition results. R/W 16 ‘h62 EEPROM ‘hD3C0 Y TON_MAX_FAULT_RESPONSE Specifies response to a TON_MAX_FAULT event. R/W 8 ‘h63 EEPROM ‘hB8 Y operaTion |
