Functions of External Input Pins
(1) PHASE Input Pin (PHASE X)
(2) ENABLE Input Pin (ENABLE X)
(3) SLEEP Input Pin
(4) C_SELECT Input Pin
Note: If the C_SELECT pin is on the mid level, channel B is turned on before channel A. If it is high, channel B is
Pin No.
This pin indicates the polarity of the H switch used in driving a DC motor. PWM can be applied by
performing time control (duty control) on this pin.
This pin indicates whether to supply the power to a DC motor to be driven.
When the level of this pin is switched from high to low or low to high, all motor drive registers are cleared
(all bits of the 16-bit latch for selecting a motor drive are cleared to low).
After the IC is shut down in motor ISD operation, changing the SLEEP signal from high to low and to high
again causes the IC to return to normal.
This pin determines which DC-DC converter to run (ON-OFF combinations) when the power is turned on.
