Chipstar Audio Amplifier Compatibility Guide for Portable Devices
The document explains how Chipstar Class‑AB and Class‑D audio amplifiers can be integrated into mobile devices. It lists the supported ICs (CS6190T, CS6105T, CS8120T, CS8115T, CS8110T) and presents a DFN 2×2_8L package layout that simplifies PCB design and re‑work.
Key features include the advantages of DFN packaging (better heat dissipation, easier transport and re‑soldering), Chipstar's AERC (Adaptive Edge Rate Control) technology for low‑EMI operation, and the AFS (Advanced Feedback System) that delivers high efficiency (>90%) and ultra‑low distortion (0.03%). The guide also provides demo‑board schematics and design tips such as differential routing and component placement. This manual is written in Chinese.

Chipstar CS803/809/810 Power Monitor Reset Circuit Datasheet
The CS803/809/810 series are low‑power reset circuits that monitor supply or battery voltage and generate a reset signal for microprocessors. They operate without external components, improving system reliability and reducing cost. When the monitored voltage falls below a preset threshold, a valid reset is output; when the voltage rises above the threshold, the reset remains active for at least 140 ms.
The series offers two output options: an open‑drain output for CS803 and CMOS outputs for CS809/810. They work over a wide temperature range (‑40 °C to +125 °C) and maintain reliable operation down to 1.15 V. The devices are supplied in a compact SOT‑23 package.
