7 / 33 page VNH3SP30-E Block diagram and pins description 7/33 Table 4. Pin functions description Name Description VCC Battery connection GNDA, GNDB Power grounds; must always be externally connected together OUTA, OUTB Power connections to the motor INA, INB Voltage controlled input pins with hysteresis, CMOS compatible. These two pins control the state of the bridge in normal operation according to the truth table (brake to VCC, brake to GND, clockwise and counterclockwise). PWM Voltage controlled input pin with hysteresis, CMOS compatible. Gates of low side FETs are modulated by the PWM signal during their ON phase allowing speed control of the motor. ENA/DIAGA, ENB/DIAGB Open drain bidirectional logic pins. These pins must be connected to an external pull up resistor. When externally pulled low, they disable half-bridge A or B. In case of fault detection (thermal shutdown of a high side FET or excessive ON state voltage drop across a low side FET), these pins are pulled low by the device (see truth table in fault condition). |
