Set current detection circuit
(1) When DEL = High
When the motor current I
M
is below the set current I
limit
, the input voltage (I
M
×
R
f
) at the – side of the current
setting amplifier is smaller than the input voltage at the + side (larger vs. ground). The drive current therefore
increases and the output pnp transistor saturates. When this condition is detected, a signal is sent to the set
current detection circuit and the RD output becomes High.
When the motor current I
M
reaches the set current I
limit
, the output pnp transistor is in the controlled state and
the RD output becomes Low.
(2) When DEL = Low
When a Low signal is input to the DEL pin, operation of the current setting amplifier is canceled. Therefore as
described above, the output transistor saturates and the RD output becomes High.
The above conditions are shown in the table below.
