Note : The "-" input unstable state. When off, a high-impedance state.

• The ENA goes to the standby state with a low-level input, and to the operating state with a high-level input.

• The control input switches the forward/reverse mode.

• The comparator and PIPR can independently control the terminal CONT. It is irrelevant to the state of IN4 from IN1.

1-4 : Output pins

H-bridge type output pins

Pins 1 and 2 are paired and pins 3 and 4 are paired.

5, 16 : Current sensing resistor connection pins

Connect the current sensing resistor between these

pins and ground to detect the output currents for

constant current control.

Pin 16 corresponds to the output from pins 1 and 2 and

pin 5 to the output from pins 1 and 2.
