General Description
The IR6224 is a 5 terminal monolithic HIGH SIDE SWITCH with
built in short circuit, over- temperature, ESD protections, 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
20A. The protection circuit latches off the high side switch if the
junction temperature exceeds 170oC and latches on after the
junction temperature falls by 10oC. The Vcc (drain) to out
(source) voltage is actively clamped at 55V, improving its performance during turn off with inductive loads.
The on-chip charge pump high side driver stage is floating and
referenced to the source of the Power MOSFET. Thus the logic
to power ground isolation can be as high as 50V. This allows
operation 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.
