Overview
The HV9967BMG-G is a single-channel LED driver IC from Microchip Technology, designed for average-mode current control. It utilizes a buck topology with an integrated 60V, 0.8Ω MOSFET switch. The device operates within an input voltage range of 8V to 60V and supports adjustable output voltage. It delivers a regulated output current of up to 750mA per channel. The component functions in temperatures ranging from -40°C to +150°C and is housed in an 8-MSOP package.
Feature Summary
- Integrates a high-voltage power MOSFET for compact design
- Provides precise average-mode current regulation
- Supports PWM dimming for brightness control
- Includes short circuit and thermal protection mechanisms
Applications
- LED backlighting systems
- General illumination lighting
- Signage applications
Procurement Notes
Verify the specific suffix 'MG' confirms the MSOP-8 package and lead-free RoHS compliance before ordering. Confirm that the operating environment stays within the specified temperature limits. Ensure the input voltage does not exceed the maximum rating of 60V. Check for moisture sensitivity handling requirements during storage and assembly. Validate that the PCB footprint matches the 8-MSOP dimensions provided in the official datasheet.
Selection Notes
Select this component when a single-channel buck converter with integrated switching is required. It is suitable for designs needing average-mode current control rather than peak-current mode. Consider the 8-MSOP package constraints for space-limited boards. Evaluate the 750mA output capability against the target LED string requirements. Ensure the application benefits from the internal protection features for reliability.
Part Context
This part belongs to the HV9967 family of integrated LED drivers. It shares functional similarities with the HV9967BK7-G, which uses an 8-DFN package. Both variants offer identical electrical performance but differ in physical housing. The series is targeted at efficient DC-DC regulation for lighting applications.
Replacement Considerations
The HV9967BK7-G is a confirmed substitute offering identical electrical specifications in an 8-DFN package. Verify pinout compatibility and thermal dissipation differences due to the package change. No other cross-model substitutes are documented in the provided data.
