27 / 84 page  Data Sheet ADP1047/ADP1048 Rev. 0 | Page 27 of 84 Name Address Description Action STATUS_VOUT (0x7A) VOUT_OV_FAULT 0x7A[7] The output voltage is above the VOUT_OV_FAULT_LIMIT. Programmable VOUT_OV_WARN 0x7A[6] The output voltage is above the VOUT_OV_WARN_LIMIT. VOUT_UV_WARN 0x7A[5] The output voltage is below the VOUT_UV_WARN_LIMIT. VOUT_UV_FAULT 0x7A[4] The output voltage is below the VOUT_UV_FAULT_LIMIT. Programmable STATUS_INPUT (0x7C) VIN_OV_FAULT 0x7C[7] The input voltage on VAC is larger than the value in VIN_OV_FAULT_LIMIT. Programmable VIN_UV_WARN 0x7C[5] The input voltage on VAC is smaller than the value in VIN_UV_WARN_LIMIT. VIN_UV_FAULT 0x7C[4] The input voltage on VAC is smaller than the value in VIN_UV_FAULT_LIMIT. Programmable VIN_LOW 0x7C[3] VAC is lower than VIN_OFF. This signal shuts down the power supply. Can set AC_OK flag IIN_OC_FAULT 0x7C[2] The input current measured on the CS ADC is larger than the value in IIN_OC_FAULT_LIMIT. Programmable IIN_OC_WARN 0x7C[1] The input current measured on the CS ADC is larger than the value in IIN_OC_WARN_LIMIT. Can set AC_OK flag PIN_OP_WARN 0x7C[0] Input overpower warning. STATUS_TEMPERATURE (0x7D) OT_FAULT 0x7D[7] The measured temperature is above the value set in OT_FAULT_LIMIT. Programmable OT_WARN 0x7D[6] The measured temperature is above the value set in OT_WARN_LIMIT. PMBus FAULT FLAG RESPONSE All standard PMBus fault response registers follow the same format. The six standard PMBus fault response registers are • VOUT_OV_FAULT_RESPONSE (Register 0x41) • VOUT_UV_FAULT_RESPONSE (Register 0x45) • OT_FAULT_RESPONSE (Register 0x50) • VIN_OV_FAULT_RESPONSE (Register 0x56) • VIN_UV_FAULT_RESPONSE (Register 0x5A) • IIN_OC_FAULT_RESPONSE (Register 0x5C) The standard PMBus fault response registers are composed of eight bits: Bits[7:6] define the response type, Bits[5:3] define the retry settings, and Bits[2:0] contain the delay information. Bits[7:6] define the response type as follows: • Bits[7:6] = 00 (ignore). When the corresponding fault flag is set, no action is taken and the power supply continues to operate normally. • Bits[7:6] = 01 or 10 (shutdown and retry). When the cor- responding fault flag is set, the system shuts down and then retries for the number of times programmed in Bits[5:3]. The difference between the 01 and 10 options is that when Bits[7:6] = 01, a debounce (programmed in Bits[2:0]) is applied to the flag. • Bits[7:6] = 11 (disable output). When the corresponding fault flag is set, the system does not enter a shutdown/soft start sequence. Instead, the output is disabled indefinitely until the flag is cleared. Care must be taken when selecting this option because it may cause the system to stall in an endless loop. Concurrent Faults When multiple faults occur at the same time, the state machine executes the response that has the highest priority. Flag priority is determined by the response of the faults as determined by Bits[7:6]. The higher the number in these two bits, the higher the priority. For example, if OVP is programmed to disable the output (Bits[7:6] = 11) and OCP is programmed to shut down and retry after a delay (Bits[7:6] = 01), and both faults occur at the same time, the OVP action is executed first. If the OVP con- dition is cleared and the OCP flag is still set, the programmed action for OCP is executed. If two or more faults occur at the same time and all the faults have the same response priority, the fault with the smallest retry setting takes priority. For example, if one fault has a retry setting programmed to 011 and the other has a retry setting of 001, the lower number of retries is executed. |
