ProchotOption1 Register (SMBus address = 34h) [reset = 8120h] 15-10 9-8 IDCHG_VTH IDCHG_DEG R/W R/W 7 6 5 4 3 2 1 0 Reserved PROCHOT_PR OFILE_IC PP_ICRIT PP_INOM PP_IDCHG PP_VSYS PP_BATPRES PP_ACOK R/W R/W R/W R/W R/W R/W R/W R/W LEGEND: R/W = Read/Write; R = Read only; -n = value after reset Table 17. ProchotOption1 Register (SMBus address = 34h) Field Descriptions SMBus BIT FIELD TYPE RESET DESCRIPTION 15-10 IDCHG_VTH R/W 000000b IDCHG Threshold 6 bit, range, range 0 A to 32256 mA, step 512 mA. There is a 128 mA offset measured current between SRN and SRP. Trigger when the discharge current is above the threshold. If the value is programmed to 000000b, PROCHOT is always triggered. Default: 16384 mA or 100000 9-8 IDCHG_DEG R/W 01b IDCHG Deglitch Time 00b: 1.6 ms 01b: 100 µs <default at POR> 10b: 6 ms 11b: 12 ms Table 18. ProchotOption1 Register (SMBus address = 34h) Field Descriptions SMBus BIT FIELD TYPE RESET DESCRIPTION 7 Reserved R/W 0b Reserved 6 PROCHOT _PROFILE_COMP R/W 0b PROCHOT Profile When all the REG0x34[6:0] bits are 0, PROCHOT function is disabled. Bit6 Independent comparator 0b: disable <default at POR> 1b: enable 5 PROCHOT _PROFILE_ICRIT R/W 1b 0b: disable 1b: enable <default at POR> 4 PROCHOT _PROFILE_INOM R/W 0b 0b: disable <default at POR> 1b: enable 3 PROCHOT _PROFILE_IDCHG R/W 0b 0b: disable <default at POR> 1b: enable 2 PROCHOT _PROFILE_VSYS R/W 0b 0b: disable <default at POR> 1b: enable 1 PROCHOT _PROFILE_BATPRES R/W 0b 0b: disable <default at POR> 1b: enable (one-shot falling edge triggered) If BATPRES is enabled in PROCHOT after the battery is removed, it will immediately send out one-shot PROCHOT pulse. |
