The IR6220 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°C and latches on after the junc-
tion temperature falls by 10°C. The drain to 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 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.
