8.3.4 Sleep or Standby Condition

The DRV10983 is available in either a sleep mode or standby mode version. The DRV10983 enters either sleep or standby to conserve energy. When the device enters either sleep or standby, the motor stops driving. The step-down regulator is disabled in the sleep mode version to conserve more energy. The I²C interface is disabled and any register data not stored in EEPROM will be reset. The step-down regulator remains active in the standby mode version. The register data is maintained, and the I²C interface remains active.

Setting sleepDis = 1 prevents the device from entering into the sleep or standby condition. If the device has already entered into sleep or standby condition, setting sleepDis = 1 will not take it out of the sleep or standby condition. During a sleep or standby condition, the Slp_Stdby status bit (address 0x10, bit 6) will be set.

For different speed command modes, Table 1 shows the timing and command to enter the sleep or standby condition.

Table 1. Conditions to Enter or Exit Sleep or Standby Condition

SPEED COMMAND MODE	ENTER STANDBY CONDITION	ENTER SLEEP CONDITION	EXIT FROM STANDBY CONDITION	EXIT FROM SLEEP CONDITION
Analog	SPEED pin voltage < V_{EN_SB} for t_{EN_SB_ANA}	SPEED pin voltage < V_{EN_SL} for t_{EN_SL_ANA}	SPEED pin voltage > V_{EX_SB} for t_{EX_ SB_ANA}	SPEED pin voltage > V_{EX_SL} for t_{EX_ SL_ANA}
PWM	SPEED pin low (V < V_{DIG_IL}) for t_{EN_SB_PWM}	SPEED pin low (V < V_{DIG_IL}) for t_{EN_SL_PWM}	SPEED pin high (V > V_{DIG_IH}) for t_{EX_SB_PWM}	SPEED pin high (V > V_{DIG_IH}) for t_{EX_SL_PWM}
I²C	SpdCtrl[8:0] is programmed as 0 for t_{EN_SB_PWM}	SpdCtrl[8:0] is programmed as 0 for t_{EN_SL_PWM}	SpdCtrl[8:0] is programmed as non-zero for t_{EX_SB_PWM}	SPEED pin high (V > V_{DIG_IH}) for t_{EX_SL_PWM}(PWM mode) or SPEED pin voltage > V_{EX_SL} for t_{EX_ SL_ANA} (Analog mode)

Note that using the analog speed command, a higher voltage is required to exit from the sleep condition than the standby condition. The I²C speed command cannot take the device out of the sleep condition because I²C communication is disabled during the sleep condition.
