Input pin for turning F2 and F4 ON and OFF

At low level F2: ON and F4: OFF; at high level, F2: OFF and F4: ON

Input pin for turning F1 and F3 ON and OFF

At low level F1: ON and F3: OFF; at high level, F1: OFF and F3: ON

Pin for turning F3 and F4 ON; At high level F31 and F42: ON

ENABLE must be set Low when VDD is rising and falling.

ENABLE must be set High to drive the motor.

Monitor pin used when either of the output short-circuit detector, overcurrent detector, or overheat detector is

activated. When the detector is activated, this pin is set low and all of F1, F2, F3 and F4 in the final stage are

latched off.

This pin connects to the motor and outputs source/sync current depending on conditions at IN1 and IN2.

OUT2

4, 6

This pin connects to the motor and outputs source/sync current depending on conditions at IN1 and IN2.

Vref

GND

19

1, 2, 3

This pin limits the peak current when motor startup.

The current setting voltage, Vref, is set to the value of 4.9 times the voltage drop of the external current

detection resistor.

The internal overcurrent detection level is 0.48V, so setting Vref < 2.0V is recommended.
