8.3.5 Sleep or Standby Condition

The DRV10983-Q1 device is available in either a sleep mode (DRV10983Q) or standby mode version (DRV10983SQ). The DRV10983-Q1 device enters either sleep or standby to conserve energy. When the device enters either sleep or standby, the device stops driving the motor. 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 is reset for the sleep mode version. The step-down regulator remains active in the standby mode version. The register data is maintained, and the I²C interface remains active for standby mode version.

For different speed command modes, 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}	See Required Sequence to Enter Sleep Mode	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)

Speed pin in DRV10983SQ (Standby version) and DRV10983Q (sleep version) should be in known state (pulled high or low) when the speed is controlled via I²C.

Note that when using the analog speed command, a higher voltage is required to exit from the sleep condition than from 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.

INPUT PWM FREQUENCY (kHz)	PWM DUTY CYCLE (%)
0.1 to 0.5	14
0.5 to 1	11
1 to 50	9
50 to 100	4
100	3.5
