13 / 20 page 000-000C55544C-105 Page 13 of 20 SLGC55544C Logic Control Modes The SLGC55544C supports the listed standards above for the SDP, CDP and DCP modes using the CTL1, CTL2, and CTL3 logic I/O control pins, although their truth tables are different as shown below. The different CTLx settings correspond to the different types of charge modes. Also, using the Auto-Detect Mode, the Divider Mode or BC1.2 (draft) / YD/T 1591-2009 can be automat- ically selected without external user interaction Note: With the SLGC55544C, if the “000” mode is selected, the power switch will be turned off and an output discharge resistor will be connected, while the data line switches will be turned off. Notes: 1. No VOUT discharge when charging between 1111 and 1110. 2. CDP Load present governed by the SMART-CDP function.
