Overview
The HV9805MG-G is a high-voltage LED driver IC manufactured by Microchip Technology, designed for offline AC-DC applications. It utilizes a boost topology to regulate current for single-channel LED loads. The device operates with an external MOSFET and supports PWM dimming capabilities. Key electrical specifications include a maximum output current of 700 mA and a fixed operating frequency of 100 kHz. It features adjustable output voltage and includes overvoltage protection. The component is housed in a compact MSOP-10 package and is rated for operation within a temperature range of -40°C to +150°C.
Feature Summary
- Integrates high-voltage startup circuitry for direct connection to AC mains without bulky transformers.
- Provides constant current regulation for LEDs using an external power MOSFET.
- Includes built-in overvoltage protection to safeguard the LED load during open-circuit conditions.
Applications
- Offline AC-DC LED lighting fixtures
- High-voltage LED string drivers
- Commercial and industrial LED ballasts
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance when ordering. Confirm the MSOP-10 package footprint matches your PCB design requirements. Ensure the external MOSFET selected is compatible with the driver's gate drive characteristics. Check for moisture sensitivity level (MSL) handling instructions if the part has been exposed to ambient conditions beyond its shelf life limits.
Selection Notes
Select this component for designs requiring a simple boost converter architecture for high-voltage LED strings. It is suitable for applications where space constraints favor the MSOP-10 package. Consider the 700 mA output limit when determining the number of series-connected LEDs. Verify that the input voltage range aligns with your local AC line specifications after rectification.
Part Context
This part belongs to Microchip's HV98xx series of high-voltage LED drivers. These devices are engineered to simplify offline LED power supply designs by integrating control logic and high-voltage startup circuits. The series targets cost-sensitive and space-constrained lighting applications, offering a robust solution for driving LED arrays directly from AC sources.
Replacement Considerations
Check Microchip datasheets for other members of the HV98xx family with similar pinouts or electrical ratings. Verify compatibility with existing PCB footprints and thermal management solutions before substituting.
