5. Function of ENABLE (output operation)
ENABLE forcibly turns OFF all output transistors at operation.
Data such as electrical angle and operating mode are all retained.
Input
Function
H
Operation enabled (active)
L
Output halted (operation other
than output active)
6. Function of
STANDBY
STANDBY halts the charge pump circuit (power supply booster circuit) as well as halting output.
We recommend setting to Standby mode at power on.
(At this time, data on the electrical angle are retained.)
