6. Saturated H-Bridge Drive
Saturated H-bridge drive mode can be implemented using the constant current drive block or the constant voltage drive blocks.
6.1 Saturated H-Bridge Drive Using Constant Current Drive Block
Saturated H-bridge drive mode using the constant current dirve block can be operated with ADJ3 connected to VREF input and cur-
rent sensing terminal RS connected to ground.
6.2 Saturated H-Bridge Drive Using Constant Voltage Drive Block
GAIN1/GAIN2 pin is open or connected to ground and ADJ1/ADJ2 input should be connected to VREF when VM1/ VM2 is less than
5V. If VM1/VM2 is more than 5V, ADJ1/ADJ2 input should be connected to power supply input.
