HCPL-0872
Digital Interface IC
Data Sheet
Lead (Pb) Free
RoHS 6 fully
compliant
RoHS 6 fully compliant options available;
-xxxE denotes a lead-free product
Description
The Digital Interface IC, HCPL-0872 converts the single-
bit data stream from the Isolated Modulator (such as
HCPL-7860/786J/7560) into fifteen-bit output words and
provides a serial output interface that is compatible with
SPI®, QSPI®, and Microwire® protocols, allowing direct
connection to a microcontroller. The Digital Interface IC,
HCPL-0872 is available in a 300-mil wide SO-16 surface-
mount package. Features of the Digital Interface IC
include five different conversion modes, three different
pre-trigger modes, offset calibration, fast over-range
detection, and adjustable threshold detection. Program-
mable features are configured via the Serial Configura-
tion port. A second multiplexed input is available to allow
measurements with a second isolated modulator without
additional hardware.
