General Description
The IR6226 is a 5 terminal monolithic HIGH SIDE SWITCH with
built in short circuit, over- temperature, ESD protections, induc-
tive load turn off capability and diagnostic feedback.
The on-chip protection circuit limits 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.
