OUT1:Hall element input pins for Phase 1.

High logic is the state when IN1+ > IN1–.

Description

OUT2: Hall element input pins for Phase 2.

High” logic is the state when IN1+ > IN1–.

OUT3: Hall element input pins for Phase 3.

High logic is the state when IN1+ > IN1–.

Output pin for Phase 1.

Output pin for Phase 2.

Output pin for Phase 3.

Power supply pin for applying voltage to each section other than output section.

Power supply for output section.

Output current detect pin; Rf is inserted between this pin and ground to detect the output current as

a voltage.

Ground for other output

The minimum potential of output transistor is at the Rf pin.

Brake pin

The brake is switched on/off by setting this pin high (2V or more)/low (0.8V or less).

Forward/Stop/Reverse control pin.

The motor is driven forward, stopped, or driven in reverse according to the voltage at this pin.

Forward : 0 to 0.8V

Stop : 2.1 to 2.9V

Reverse : 4.2 to 5.0V

Power pin for Hall elements

When using the internal (stabilized) power supply : VH=7V typ.

When using the external (stabilized) power supply : VH=5V typ.

Sets the oscillation frequency for the switching regulator/

Outputs duty-controlled pulsed ; open collector output.

Speed control pin ; varies the swithcing regulator output votlage.

Suppresses ripples in the motor current during operation of current limiter 2.
