PRODUCTION DATA.
MODE | DESCRIPTION |
---|---|
OFF | This is the lowest-power mode of operation. All power functions are turned off, registers are reset to their default values, and the IC does not respond to SPI commands. RESETZ pin is pulled low. The IC will enter OFF mode whenever the PROJ_ON pin is low. |
STANDBY | The DMD regulators and LED power (VLED) are turned off, but the IC does respond to the SPI. The device enters STANDBY mode whenever PROJ_ON is set high or DMD_EN(1) bit is set to 0 using the SPI interface after PROJ_ON is already high. The device also enters STANDBY mode when a fault condition is detected(2). (See Protection Circuits). |
ACTIVE1 | The DMD supplies are enabled but LED power (VLED) is disabled. PROJ_ON pin must be high, DMD_EN bit must be set to 1, and VLED_EN(3) bit is set to 0. |
ACTIVE2 | DMD supplies and LED power are enabled. PROJ_ON pin must be high and DMD_EN and VLED_EN bits must both be set to 1. |
PROJ_ON PIN | STATE |
---|---|
LOW | OFF |
HIGH | STANDBY ACTIVE1 ACTIVE2 (Device state depends on DMD_EN and VLED_EN bits and whether there are any fault conditions.) |
