Output
Output
High side current sensing (Insert an external resistor between VM and VHS. When the voltage across this resistor reaches 0.5 V,
the outputs are turned off.)
Low side current sensing (Insert an external resistor between VLS and ground. When the voltage across this resistor reaches
0.5 V, the outputs are turned off.)
Connection for an external filter capacitor that prevents incorrect operation of the current sensing output shutdown and thermal
shutdown circuits.
Motor system power supply
Logic system power supply
Forward/reverse switching pin
Brake control input. A high input switches the IC to brake mode.
Standby mode control. The IC operates in standby mode when this pin is low or open.
PWM input. High: on
Low: off
Low side drive current switching. (Short R to VCC when VCC is 3.3 V, and leave R open when VCC = 5.0 V.)
Ground
Lower side regeneration diode ground connection
No. 7391-3/6
