    Products Detail

    The LM4651 is a fully integrated conventional pulse width modulator driver IC with short circuit, under voltage, over modulation, and thermal shutdown protection. The LM4652 is a fully integrated H-bridge power MOSFET IC in a TO-220 package with built-in temperature sensing. Together, they form a compact high-power audio amplifier solution with protection features typically seen in Class AB amplifiers. The near rail-to-rail switching amplifier significantly increases efficiency compared to Class AB amplifiers, reducing heat sink size. This two-chip solution is optimal for powered subwoofers and self-powered speakers.

    Key Features

    • Conventional Pulse Width Modulation, Externally Controllable Switching Frequency, 50kHz to 200kHz Switching Frequency Range, Integrated Error Amp and Feedback Amp, Turn−on Soft Start and Under Voltage Lockout, Over Modulation Protection (Soft Clipping), Externally Controllable Output Current Limiting and Thermal Shutdown Protection, Self Checking Protection Diagnostic

    Application scenarios

    • Powered Subwoofers for Home Theater and PC's
    • Car Booster Amplifier
    • Self-powered Speakers
