When the voltage across this resistor reaches 0.5 V, the outputs are turned off.) 2 VLS 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.) 7 C Connection for an external filter capacitor that prevents incorrect operation of the current sensing output shutdown and thermal shutdown circuits. 3 VM Motor system power supply 5 VCC Logic system power supply 9 PHASE Forward/reverse switching pin 10 BRAKE Brake control input. A high input switches the IC to brake mode. 6 ST Standby mode control. The IC operates in standby mode when this pin is low or open. 8 PWM PWM input. High: on Low: off 12 R Low side drive current switching. (Short R to VCC when VCC is 3.3 V, and leave R open when VCC = 5.0 V.) 11 GND Ground 13 DiGND Lower side regeneration diode ground connection |
