IR6216

The IR6216 is a 5 terminal monolithic HIGH SIDE SWITCH with built in short circuit, over- temperature, ESD, inductive load turn off capability and diagnostic feedback.

The on-chip protection circuit goes into PWM mode, limiting the average current during short circuit if the drain current exceeds 5A.  The protection circuit latches off the high side switch if the junction temperature exceeds 170!aC  and latches on after the junc tion temperature falls by 10!aC.  The drain to source voltage iactively clamped at 55V, improving its performance during turnoff with inductive loads.

The on-chip charge pump high side driver stage is floating and ref-erenced to the source of the power MOSFET. Thus the logic to power ground isolation can be as high as 50V. This allows opera- tion with larger offset as well as controlling the switch during load energy recirculation or regeneration.

A diagnostic pin is provided for status feedback of short circuit, over temperature and open load detection.
