Substrate temperatures in the figure above are values measured when the motor is operating.
The temperature Tc varies with the ambient temperature Ta, the motor drive current, and whether the motor current is continuous or
the state of its intermittent operation. Therefore Tc must be verified in an actual end product system.

Notes
(1) The value of the power supply bypass capacitor C1 must be set so that the capacitor ripple current, which
changes with the motor current, remains within the allowable range.
(2) While the Vref2 pin is normally handled by being left open, note that the thermal protection circuit will no
longer operate if this pin is connected to ground or the P.S pin.
(3) Current is controlled by a constant-current chopping operation by transistors TR1 and TR2. The timing for
the OUT1 or OUT2 output voltage and the TR1 or TR2 collector current is shown below.
(4) Do not connect or wire any of the NC (unused) pins that appear in either the block diagram or the
application circuit examples to the circuit pattern on the PCB.

(5) Since the response time of the ground side drive element during forward/reverse direction switching is a
few tens of microseconds, this product is not appropriate for H bridge applications. This device should only
be used as a DC motor driver.

0.42 V is set by connecting 82 kΩ and 7.5 kΩ in series.
Current detection resistance is Rs = 0.10 Ω. set using IO peak = Vref1 ÷ Rs
It is to be noted, there is a CR time constant delay in RSI input.
Io peak load conditions (load specs and power supply specifications) will vary (increase).
Please check with the actual machine.
Be sure to usually leave this pin open.
The overheating control curcut can be made to stop operating by connecting this pin to Gnd or S.P pin.
