LCD segment driver — 40 outputs, I²C control
The PCA85176H/Q900/1,5 from NXP is a 40-segment LCD driver IC that communicates over an I²C bus, making it a straightforward add-on for any MCU with a spare I²C port. The 40 segment outputs drive up to 40 LCD elements directly — enough for a 7-digit numeric display with decimal points and annunciators, or a custom icon-based panel. Quiescent current is 3.5 µA typical — low enough that the driver can stay powered in a battery-backed system without draining the coin cell.
Active production and compliance
ROHS3 compliant, so it ships lead-free and meets the current EU restriction directive without exemption declarations.
