Both the high-voltage supply current limit and the V3P3 supply current limit are adjustable by external resistors. Figure 1. Simplified Current Limit Diagram The current IREF_HV and IREF_V3P3 that set the current limit threshold are set with three external resistors as shown in Figure 2. When the TPS22981 is passing the V3P3 voltage, the current limit is set by RSET_V3P3. The VHV path has two modes that allow setting two different current limits. The S0 pin determines which current limit is used. When S0 is asserted high, RSET_S0 sets the current limit. When S0 is low, RSET_S3 sets the current limit. This allows the system to have two separate VHV current limits for different modes such as active and sleep. Figure 2.
