layout are optimized within the device.

with hysteresis, over-voltage protection, and thermal shutdown protect

the devices during all normal and overload conditions. Over-voltage

protection, thermal shutdown, or an external fault signal are latched.

The dual requirements of dielectric isolation and low transient thermal

impedance and steady-state thermal resistance are satisfied in an over-

molded single-in-line power package.
