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.)
