OUT1
12
Input pin for turning F1 and F3 ON and OFF
At high level, F1: ON and F3: OFF; at low level F1: OFF and F3: ON
13
Input pin for turning F2 and F4 ON and OFF
At high level, F2: ON and F4: OFF; at low level, F2: OFF and F4: ON
14
Pin for turning F1 and F2 OFF; At high level F1 and F2: OFF
This pin is usually low or open.
8
This pin connects to the motor and outputs source/sync current depending on conditions at IN1 and IN2.
OUT2
6
This pin connects to the motor and outputs source/sync current depending on conditions at IN1 and IN2.
Vref1a
Vref1b
Vref2
16
This pin is used for current setting for constant-current operation performed with the Vrefa and Vrefb pins
18
connected
A voltage of 0.29V at Tc=25°C results for Vref1.
0.29V is set by connecting 82kΩ and 5.1kΩ in series.
Current detection resistance is Rs=0.056Ω. Set using IO peak=Vref1÷Rs.
17
Be sure to usually leave this pin open.
The overheating control circuit can be made to stop operating by connecting this pin to the GND or S.P pin.
S.P
2
Vref1 voltage can be lowered by connecting a resistor between the Vref1 and S.P pins.
RSO
RSI
3
This pin is used to monitor the voltage across the current sensing resistor, Rs. Must be connected to the RSI
pin.
19
This pin is connected to the RSO pin and serves as an input to the circuit that compares the input with Vref1.
