8. Various Protections
(1)
Overcurrent Protection (RS pin)
When a DC link current exceeds the internal reference voltage, output transistors are turned off. The
TB6585FG exits overcurrent protection mode every carrier cycle. Reference voltage = 0.5 V (typ.)
(2)
External RESET (RESET pin)
Output transistors are turned off when RESET is High; they are turned on again when RESET is Low
or Open.
The RESET pin is activated if any abnormality is detected externally.
(3)
Internal Protections
Position Detection Fault Protection
When the position detection signals are all set to High or Low, output transistors are turned off.
Otherwise, the motor is restarted every carrier cycle.
Anti-lock capability
When the operation mode is not properly switched as configured from 120
°
commutation mode of
startup operation to 180° commutation mode, the motor is deemed to be locked and output
transistors are turned off. The restart operation can be selected from either the automatic restart
or the power cycling.
<
Setting the Time of Motor-Lock Detection and the Time While the Motor is Stationary
>
The time required for the motor-lock detection and the time while the motor driving signal is
inactive can be adjusted by the external capacitor C
1
. (These periods are set to be the same.)

Automatic Restart (ML
=
High)
>
When the Hall signal frequency is kept below 2.5 Hz for at least 500 ms (typ.), the TB6585FG
becomes active and inactive periodically every 500 ms (typ.). The protection is disabled when
the Hall signal frequency reaches 2.5 Hz and the operation mode is switched to 180°
commutation mode.
<
Restart with Power Cycling (ML
=
Open or Low)
>
When the Hall signal frequency is kept below 2.5 Hz for at least 500 ms (typ.), output
transistors are disabled. The TB6585FG can be restarted by turning off and back on the V
M
power supply, which must be kept below 3.5 V (typ.). The TB6585FG can also be restarted by
turning off and back on Vsp, which must be kept below 1 V (typ.).
