3.6.9 Driving Capability

Driving Capability is specified as load impedance. Over current detection characteristics is designed above Driving

Capability characteristics. If estimated load impedance which comes from peak inrush current is lower than Driving

Capability characteristics, this means, the device does not detect inrush current as over current and does not shutdown

the output. Depend on the conditions, Power Limitation function may work during inrush current. If estimated load

impedance which comes from peak inrush current is lower than Driving Capability characteristics, Power limitation

disappear within 30ms. This parameter does not mean that the device can drive the resistive load up to Driving

Capability characteristics.

3.6.10 Cross current protection in case of H-bridge high side usage

In case of using High side driver in H-bridge circuit,

High side driver protects High side driver itself

and also low side driver from high power dissipation

by cross current when low side driver switching on.
