This document describes the technical specifications and features of the TDA4841PS integrated circuit, which is an I2C-bus autosync deflection controller for PC monitors.
The Philips TDA4841PS is an I2C‑bus controlled autosync deflection controller designed for PC monitors. It provides full horizontal and vertical autosync capability, extended frequency range (15‑130 kHz), and a comprehensive set of geometry adjustments such as pin unbalance, parallelogram correction, and focus control. The device includes protection features like X‑ray protection, power‑dip recognition, and soft‑start sequences for safe operation.
The IC is supplied in an SDIP‑32 package and offers a wide range of programmable outputs, including horizontal and vertical driver signals, video clamping, and synchronization outputs. Detailed pin descriptions, functional block diagrams, and specifications such as supply voltage, current consumption, and temperature range are provided for designers integrating the controller into monitor designs.
| Supply voltage (Voc) | 9.2 – 13.2 V |
|---|---|
