Pin Description

PWRGD (ISL6140; L Version) Pin 1

This digital output is an open-drain pull-down device.

The Power Good comparator looks at the DRAIN pin

voltage compared to the internal VPG reference (VPG is

nominal 1.7V); this essentially measures the voltage

drop across the external FET and sense resistor. If the

voltage drop is small (<1.7V is normal), the PWRGD

pin pulls low (to VEE); this can be used as an active

low enable for an external module. If the voltage drop

is too large (>1.7V indicates some kind of short or

overload condition), the pull-down device shuts off,

and the pin becomes high impedance. Typically, an

external pull-up of some kind is used to pull the pin

high (many brick regulators have a pull-up function

built in).

PWRGD (ISL6150; H Version) Pin 1

This digital output is a variation of an open-drain

pull-down device. The power good comparator is the

same as described above, but the polarity of the output

is reversed, as follows:

NOTES:

1. Please refer to TB347 for details on reel specifications.

2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach

materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both

SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that

meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
