7.4.2 Output State Control

The TPS65295 has two enable input pins, SLP_S4 and VTT_CNTL, to provide simple control scheme of output state. All of VPP, VDDQ, VTTREF and VTT are turned on at S0 state (SLP_S4=VTT_CNTL=high). In S3 state (VTT_CNTL=low, SLP_S4=high), VPP, VDDQ, and VTTREF voltages are kept on while VTT is turned off and left at high impedance state (high-Z). The VTT output floats and does not sink or source current in this state. In S4/S5 states (SLP_S4=VTT_CNTL =low), all of the three outputs are turned off and discharged to GND. Each state code represents as follow: S0 = full ON, S3 = suspend to RAM (STR), S4 = suspend to disk (STD), S5 = soft OFF (see Table 1).

Table 1. VTT_CNTL and SLP_S4 Control for Output State

STATE VTT_CNTL SLP_S4 VPP VDDQ VTTREF VTT
S0 HI HI ON ON ON ON
S3 LO HI ON ON ON OFF (High-Z)
S5/S4 LO LO OFF (discharge) OFF (discharge) OFF (discharge) OFF (discharge)
