Description
The M61556FP is a predriver IC developed for use as the output driver of a digital audio power amplifier. It can be
combined with an N-channel MOSFET to create a 100 W, 1-channel (8Ω load) digital amplifier. (The 200 W version,
the M61557FP, is pin compatible with the M61556FP.)
Features
• On-chip dead time adjustment circuit: Supports easy adjustment by connecting a single resistor. (H-L dead time can
be fine adjusted independently for sides A and B.)
• Suitable for driving full-bridge N-channel MOSFET devices.
• Maximum bootstrap supply voltage: 88 V (peak value)
• Supports high-speed switching.
• On-chip diode for bootstrap circuit.
• On-chip VDD low voltage detector circuit.
• On-chip clock loss detector circuit.
• Output impedance: 2.5 Ω
• Input is TTL level, allowing connecting to 3.3 V or 5 V processors.
