描述
The LDM must monitor the headlamp PCBA temperatures with NTC thermistors to thermally derate LED functions current to protect the headlamp. The temperatures are monitored with 4 NTC (negative temperature coefficient) thermistors which located on LED boards external to the LDM but within the headlamp assembly, placed as close as possible to the hottest board location.
Each channel can choose a NTC source to determine which NTC temperature shall be used for the corresponding function, it can be configured by parameter ‘Channelx_NTC_Source_cfg’.
‘Channelx_NTC_Source_cfg’ definition:
• 0x00: NOT USED
• 0x01: NTC1
• 0x02: NTC2
• 0x03: NTC3
• 0x04: NTC4
