FOperation notes

(1)

Thermal shutdown circuit

The IC has a built-in thermal shutdown circuit. The circuit

turns off all the driver outputs when the chip junction tem-

perature rises to about 175

_C (typical). There is a tem-

perature difference of 20

_C (typical) between the tem-

peratures at which the circuit is activated and

deactivated.

(2)

Vctl, Vref, and input pins

er outputs are turned on and a current may flow through

the connected motor. The voltage of each input pin

age.

(3)

Temperature dependence of quiescent circuit cur-

to the temperature dependence of the standby current

that flows through the high- and low-side transistors.

(4)

Package power dissipation

The IC power dissipation changes greatly with the supply

voltage and the output current. Give full consideration to

the power dissipation rating when setting the supply volt-

age and the output current.
