Youan Semiconductor Power Management Chip U6514 Introduction

Youan Semiconductor Power Management Chip U6514 is a high-performance, low-cost primary control power switch, built-in high pressure power triode, providing high-precision constant voltage and constant current performance, particularly suitable for small power off-line charger applications. Using U6514 can work without no sound, while ensuring excellent dynamic performance. Using the integrated line loss compensation function, high-performance constant voltage output performance can be obtained. Youan Semiconductor Power Management Chip U6514 Integration has a variety of protection functions: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), circumferential period flow protection (OCP), short circuit protection (FB SLP), output overvoltage Protection (FBOVP), overheating protection (OTP), and VDD clamping. The U6514 is also integrated with power system single point failure protection, in the FB pull-up resistor opening, FB pull-down electric resistance opening, FB pull-down electric resistance short circuit, output diode or SR open circuit, output diode or SR short circuit, transformer winding short circuit, RCS open circuit, etc. under fault conditions It can be protected. When playing while playing while playing the phone, the friend's semiconductor power management chip U6514 will charge the battery according to the electricity demand, and the other part supplies the mobile phone circuit. In this way, the charging speed will naturally be slower. If it is a small power charger or uses a very poor quality or damaged data cable, the amount of power may be more and less. From the speed and safety perspective, avoid playing mobile phones while charging while charging, using a formal non-destructive charger and data cable to effectively avoid risks and increase the rate.
