Figure 50. CONFIG_COVT Register 7 6 5 4 3 2 1 0 µs/ms Reserved COVD[4] COVD[3] COVD[2] COVD[1] COVD[0] Table 23. CONFIG_COVT Register Field Descriptions Bit Field Type Reset Description 7 µs/ms Determines the units of the delay time, microseconds or milliseconds 0 = Microseconds 1 = Milliseconds 6-5 Reserved 4-0 COVD[n] 0x01 = 100; each binary increment adds 100 until 0x1f = 3100 Note: When this register is programmed to 0x00, the delay becomes 0s AND the COV state is NOT latched in the COV_FAULT register. In this operating mode, the overvoltage state for a cell is virtually instantaneous in the COV_FAULT register. This mode may cause system firmware to miss a dangerous cell overvoltage condition. 7.6.28 CONFIG_UV Register (0x44) The CUV register determines cell under voltage threshold voltage. Figure 51. CONFIG_UV Register 7 6 5 4 3 2 1 0 DISABLE Reserved CUV[4] CUV[3] CUV[2] CUV[1] CUV[0] Table 24. CONFIG_UV Register Field Descriptions Bit Field Type Reset Description 7 DISABLE Disables the undervoltage function when set 0 = Undervoltage function enabled 1 = Undervoltage function disabled 6-5 Reserved 4-0 COVD[n] Configuration bits with corresponding voltage threshold 0x00 = 0.7 V; each binary increment adds 100 mV until 0x1a = 3.3 V 7.6.29 CONFIG_CUVT Register (0x45) The CONFIG_CUVT register determines cell undervoltage detection delay time. Figure 52. CONFIG_CUVT Register 7 6 5 4 3 2 1 0 µs/ms Reserved CUVD[4] CUVD[3] CUVD[2] CUVD[1] CUVD[0] 52 Submit Documentation Feedback Copyright © 2011–2016, Texas Instruments Incorporated Product Folder Links: bq76PL536A |
