PRODUCTION DATA
In standby mode the gate driver, AVDD LDO and I2C bus are active. The device can be configured to enter standby mode by configuring DEV_MODE to 0b. The device enters standby mode when the reference command after the profiler is zero.
The thresholds for entering and exiting standby mode in different input modes are as follows,
| Control Input Source | Standby entry/exit thresholds | REF_PROFILE_CONFIG = 00b | REF_PROFILE_CONFIG ≠ 00b |
|---|---|---|---|
| Analog | VEN_SB or VEX_SB | Maximum of (1%, DUTY_HYS) x VANA_FS | REF_X = 1% of MAX_SPEED or MAX_POWER or ILIMIT or MODULATION INDEX |
| PWM | DutyEN_SB or DutyEX_SB | Maximum of (1%, DUTY_HYS) | REF_X = 1% of MAX_SPEED or MAX_POWER or ILIMIT or MODULATION INDEX |
| I2C | DIGITAL_SPEED_CTRLEN_SB or DIGITAL_SPEED_CTRLEX_SB | Maximum of (1%, DUTY_HYS) x 32767 | REF_X = 1% of MAX_SPEED or MAX_POWER or ILIMIT or MODULATION INDEX |
| Frequency | FreqEN_SB or FreqEX_SB | Maximum of (1%, DUTY_HYS) x INPUT_MAXIMUM_FREQ (subject to minimum of 3Hz) | REF_X = 1% of MAX_SPEED or MAX_POWER or ILIMIT or MODULATION INDEX |
