Overview
The FPA6101MTCX is a monolithic stereo audio power amplifier and capacitor-less headphone driver manufactured by onsemi. It operates with a supply voltage of 4.5V to 5.5V for the main section and 3.0V to 3.6V for the headphone section. The device delivers up to 2.4W output power in speaker mode and includes integrated de-pop circuitry, thermal shutdown, and over-current protection. It utilizes a TSSOP-28P surface-mount package.
Feature Summary
- Integrates a stereo power amplifier and a ground-referenced capacitor-less headphone driver within a single IC.
- Features internal gain setting and charge pump technology to eliminate external coupling capacitors.
- Includes integrated de-pop circuitry to reduce pops and clicks during power-up and shutdown transitions.
- Provides comprehensive protection mechanisms including thermal shutdown and over-current limiting.
Applications
- Notebook PCs
- LCD TVs and Monitors
- Portable DVD, CD, or HDTV players
- Portable Radios
- Portable Games
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the part matches the specified TSSOP-28P package and RoHS compliance status. Review the datasheet for absolute maximum ratings and operating conditions to ensure compatibility with target system voltages and thermal requirements before integration.
Selection Notes
Select this component for designs requiring combined speaker amplification and direct-drive headphone outputs without external coupling capacitors. Ensure the application supports the required 4.5V to 5.5V supply range. Consider the TSSOP-28P package dimensions and thermal pad requirements for adequate heat dissipation in space-constrained portable electronics.
Part Context
The FPA6101 series represents a family of stereo audio amplifiers designed for low-voltage consumer electronics. The MTCX suffix specifically denotes the TSSOP-28P package variant. This component consolidates multiple audio functions into a compact form factor, reducing PCB area and supporting cost-effective designs for portable multimedia devices.

FAQ
How does the FPA6101 eliminate the need for output capacitors?
The speaker amplifier uses a bridge-tied load (BTL) configuration, while the headphone driver employs a charge pump to create a bipolar supply from a single source, allowing ground-referenced outputs without DC blocking capacitors.
What is the function of the SD pin?
The SD (Shutdown) pin controls the device's power state. Pulling this pin LOW activates shutdown mode, significantly reducing supply current to approximately 80µA.
