2) H- bridge drive using voltage drive block
When VB1 and VB2 power is less than 5V, VC1/VC2 input should be connected to VREF or motor supply and VB1 and VB2
power is more than 5V, VC1/VC2 input should be connected to motor supply. In H-bridge drive mode, a capacitor to prevent
oscillation is not necessary on both sides of the output.
6. Short through protection
When a motor is driven, high/low side TR turn on simultaneously. This range may cause power to be shorted to ground
momentarily. To prevent a short through, output is generated with a 1.8us(typical) delay after a high input signal.
7. Brake function
The brake function is built in Ch3,4 and CH6 . Using the H/H signal on input, it is designed so that a short brake is operated on
output.
8. Power Supply
VB1,VB2,VCC1 and VCC2 are separated for motor power of FAN8702 and VDD is used for IC logic power.
VB1,VB2,VCC1 and VCC2 are correspond to H-bridge 1~2, H-bridge 3~4, H-bridge 5 and H-bridge6.
9. Thermal shutdown
When thermal shut down is activated, all the outputs become off except for VREF.
