Huajing Microelectronics CS6515 ○R LED Constant Current Driver Datasheet
The CS6515 ○R is an offline, low‑power AC/DC switching power supply LED driver that operates over a wide input range of 85Vac to 265Vac. It uses primary‑side feedback to regulate LED current without secondary optocouplers, providing high‑precision constant‑current output while reducing cost.
The device integrates multiple protection features, including VCC under‑voltage lockout, LED open‑ and short‑circuit protection, cycle‑by‑cycle current limiting, over‑voltage, and over‑temperature protection, all with automatic restart. Electrical specifications, pin assignments, and typical application circuits are detailed in the following sections. This manual is written in Chinese.

Questions answered in 华润华晶微电子有限公司 manuals
How does the device protect against LED open‑circuit conditions?
When an LED open occurs and VCC exceeds 14.5 V, the internal logic discharges the VCC capacitor, causing VCC to fluctuate around 14.5 V and the output voltage follows, providing open‑circuit protection.

What is the over‑temperature shutdown temperature?
The over‑temperature protection shuts down the chip at 160 °C and restarts only after the temperature falls below 130 °C.
