DATASHEET
Bits 2 - 0 - ILIM_SW[2:0] - Sets the ILIM value as shown in Table 10.12.
10.6
Charge Rationing Threshold Registers
The Charge Rationing Threshold registers set the maximum allowed charge that will be delivered to a
portable device. Every time the Total Accumulated Charge registers are updated, the value is checked
against this limit. If the value meets or exceeds this limit, the RATION bit is set (see Section 10.4.1)
and action taken according to the RATION_BEH[1:0] bits (see Section 10.4.1).
The units are in mA-hrs with a range from 0 to ~181768.
The contents of this register are retained in Sleep.
