в–єв–є Maximum quiescent current of 50ВµA Applications General Description The HV7802 high side current monitor IC contains a
transconductance amplifier which translates a high side
current measurement voltage into an output current with
resistor programmable transconductance gain. An optional
second resistor transforms this output current into an output
voltage with an overall voltage gain set by the ratio of the two
resistors.
The measurement voltage typically originates at a current
sense resistor, which is located in a “high side” circuit, for
example a circuit not directly associated with ground. в–єв–є SMPS current monitor
в–єв–є Battery current monitor
в–єв–є Motor control This monitor IC features a very wide input voltage range,
configurable gain, small size, low component count, low power
consumption, ease of use, and low cost. Offline, battery, and
portable applications can be served equally well due to the …
