HCPL-7860-000E

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P17
Description
The HCPL-7860/HCPL-786J Optically Isolated Modulator
and HCPL-0872 Digital Interface IC or digital lter together
form an isolated programmable two-chip analog-to-digital
converter. The isolated modulator allows direct measure-
ment of motor phase currents in power inverters.
In operation, the HCPL-7860/HCPL-786J Isolated Modula-
tor converts a low-bandwidth analog input into a high-
speed one-bit data stream by means of a Sigma-Delta
(Σ−∆) over-sampling modulator. This modulation provides
for high noise margins and excellent immunity against
isolation-mode transients. The modulator data and on-
chip sampling clock are encoded and transmitted across
the isolation boundary where they are recovered and de-
coded into separate high-speed clock and data channels.
NOTE: A 0.1 μF bypass capacitor must be connected between pins VDD1 and GND1 and between pins VDD2 and GND2.
