Product details

GENERAL DESCRIPTION

The HA8500 is a high performance Primary Side Regulation (PSR) controller with high precision CV/CC control ideal for charger applications.  
In CV mode, the HA8500 adopts Multi Mode Control which uses the hybrid of AM (Amplitude Modulation) mode and (Frequency Modulation) FM mode to improve system efficiency and reliability.  
In CC mode, the HA8500 uses PFM control with line and load CC compensation. The HA8500 can achieve audio noise free operation and optimized dynamic response. The built-in Cable Drop Compensation (CDC) function can provide excellent CV performance.
The HA8500 integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Cycle-by-cycle Current Limiting (OCP), Short Load Protection (SLP), Gate Clamping, and VDD Clamping.
The HA8500 is available in SOT23-5 package.
