Manufacturer
ZETEX [Zetex Semiconductors]
Datasheet
ZXCT1030
High-side current monitor with comparator
Description
The ZXCT1030 is a high side current sense
monitor containing an internal reference and
comparator with a non-latching output. Using
this device eliminates the need to disrupt the
ground plane when sensing a load current.
