SLGC55545

Logic Control Modes

The SLGC55545 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 SLGC55545, 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:

Functionality.

2. DCP Load present governed by the “Power Wake” limits.

3. DCP Load present governed by the “Non-Power Wake” limits.

4. No VOUT discharge when charging between 1111 and 1110.

5. CDP Load present governed by the “Non-Power Wake” limits.
