Table 1-2 shows the timing and command to enter the sleep or standby condition. In I2C speed command mode, Sequence is required to enter sleep mode. The Speed pin must be in a known state (pulled high and pull low) when the speed is controlled via I2C.
| Speed Command Mode | Enter Standby Condition | Enter Sleep Condition | Exit From Standby Condition | Exit From Sleep Condition |
|---|---|---|---|---|
| Analog | SPEED pin voltage < VEN_SB for tEN_SB_ANA | SPEED pin voltage < VEN_SL for tEN_SL_ANA | SPEED pin voltage > VEX_SB for tEX_ SB_ANA | SPEED pin voltage > VEX_SL for tEX_SL_ANA |
| PWM | SPEED pin low (V < VDIG_IL) for tEN_SB_PWM | SPEED pin low (V < VDIG_IL) for tEN_SL_PWM | SPEED pin high (V > VDIG_IH) for tEX_SB_PWM | SPEED pin high (V > VDIG_IH) for tEX_SL_PWM |
| I2C | SpdCtrl[8:0] is programmed as 0 for tEN_SB_PWM | Required Sequence to Enter Sleep Mode | SpdCtrl[8:0] is programmed as non-zero for tEX_SB_PWM | SPEED pin high (V > VDIG_IH) for tEX_SL_PWM (PWM mode) or SPEED pin voltage > VEX_SL for tEX_SL_ANA (Analog mode) |
