Status: In Production
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. 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 wide input voltage range and the low quiescent current.
