ZQL9712 chip is a chip designed for LED driver applications, with features such as low power consumption and optimized interface for multi-chip cascading applications.
The ZQL9712 LED driver chip is designed for LED display systems, providing three high‑current driver outputs (up to 30 mA) and a row latch that converts inputs to a 3‑bit parallel output. It operates with a low‑power CMOS process and includes separate clock controls for the row and output latches.
The device is offered in multiple packages (DIP, DIE, COB1, COB2, TSSOP) and features a 5 V CMOS supply, 15 MHz clock, 600 mW power dissipation, and an operating temperature range of –40 °C to +85 °C. Electrical characteristics such as VDD, VOUT, VIN, and IOUT are detailed in the datasheet. This manual is written in Chinese.
