Output of the channels 1/2/3.
Logic input of channels 1/2/3. A logic HIGH level (when the corresponding
EN pin is HIGH) switches ON the upper DMOS Power Transistor, while a
logic LOW switches ON the corresponding low side DMOS Power.
Enable of the channels 1/2/3. A logic LOW level on this pin switches off both
power DMOS of the related channel.
Power Supply Voltage.
A resistance Rsense connected to this pin provides feedback for motor
current control for the bridge 3.
A resistance Rsense connected to this pin provides feedback for motor
current control for the bridges 1 and 2.
Internal Voltage Reference. A capacitor connected from this pin to GND
increases the stability of the Power DMOS drive circuit.
Bootstrap Oscillator. Oscillator output for the external charge pump.
Overvoltage input to drive the upper DMOS
Common Ground Terminal. In Powerdip and SO packages these pins are
used to dissipate the heat forward the PCB.
