FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
• if the device was in Fail mode, the failure is locked until
For OCHI2 and OCLO:
• if the device was in Normal mode: the output
• if the device was in Fail mode, Autorestart is activated.
The SPI fault reports are removed after a read operation:
Application of complete OCHI window depends on
toggling or not toggling D7 bit.
restart of the device: wake-up from Sleep mode or
V
corresponding register (bit D7) must be rewritten D7=1.
Application of complete OCHI window depends on
toggling or not toggling D7 bit.
The device Autorestart feature provides a fixed duty
cycle and fixed period with OCHI1 window.
Autorestart feature resets OCHI2 or OCLO fault after
corresponding Autorestart period.
