Figure 5. Application Drawing
Any combination of motors and high side drivers can be designed in. This allows for flexibility in many systems.
H ? Bridge Driver Configuration
The NCV7708B has the flexibility of controlling each
driver independently. When the device is set up in an
H ? Bridge configuration, the software design has to take care
of avoiding simultaneous activation of connected HS and LS
transistors. Resulting high shoot through currents could
cause irreversible damage to the device.
Overvoltage Clamping ? Driving Inductive Loads
To avoid excessive voltages when driving inductive loads
in a single ? side ? mode (LS or HS switch, no freewheeling
path), the NCV7708B provides internal clamping diodes.
Thus any load type can be driven without the requirement of
external freewheeling diodes. Due to high power dissipation
during clamping, the maximum energy capability of the
driver transistor has to be considered.
