Notes
 The motor current Io shown above is the range for DC and chopping operation.
The DC operating current range is within both the allowable Vcc1 operating range and the derating curve shown in the figure.
 The operating 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.
 The Tc temperature should be checked in the center of the metal surface of the product package.

Function
The state where the motor is not turning
Power supply to the motor was turned off
due to a stop signal being applied during
motor operation.
An input signal that turns off the high and
low side drive elements during
forward/reverse switching is not required.
The ground side MOSFET is in the on
state.
* The state IN1 = IN2 = high, PWM = L is illegal during motor operation.
* PWM pin (14pin) is active Low.
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 F1 and F2. The timing for the OUT1 or
OUT2 output voltage and the F1 or F2 drain 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.

This pin should normally be left open.
Connecting this pin to ground or the S.P pin disables the thermal protection circuit.
