Description
The M61558FP is a power driver IC for digital power amplifiers. The IC incorporates both pre-drivers and the output-
stage n-channel power MOS FET, for a single chip implementation of a 30-W single-channel digital amplifier for audio
applications.
Features
• On-chip n-channel power MOS FET
• Fast PWM switching operation
• On-chip diode for boot strap
• Various on-chip protective circuits
 VDD under detection circuit
 Over-Temperature protection circuit
 Over-current protection circuit
Recommended Operating Conditions
Power-supply voltage for pre-drive stage: VDD = 12 V (pre-driver stage power-supply voltage)
Output-stage power-supply voltage: VD = 21 V (typ.) < 16 V (min.) to 24 V (max.), RL = 4 (min.), 6 (typ.), 8 (max.) Ω
