Description
The HCPL-7860/HCPL-786J Optically Isolated Modulator
and HCPL-0872 Digital Interface IC or digital filter 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.
Features
• 12-bit Linearity
• 200 ns Conversion Time
(Pre-Trigger Mode 2 with HCPL-0872)
• 12-bit Effective Resolution with 5 µs Signal Delay
(14-bit with 102 µs) (with HCPL-0872)
• Fast 3 µs Over-Range Detection (with HCPL-0872)
• ± 200 mV Input Range with Single 5 V Supply
• 1% Internal Reference Voltage Matching
• Offset Calibration (with HCPL-0872)
• -40°C to +85°C Operating Temperature Range
• 15 kV/µs Isolation Transient Immunity
• Safety Approval: UL 1577, CSA and IEC/EN/DIN EN
60747-5-5
Applications
• Motor Phase and Rail Current Sensing
