HA13119 Dual 5.5 W Audio Power Amplifier Description The HA13119 is power IC designed for car radio and car stereo amplifiers. At 13.2 V to 4 Ω load, this power IC provides output power of 5.5 W with 10 % distortion. It is easy to design as this IC employs internal each protection circuit and the new small package. Features • Low distortion THD = 0.1% typ (Po = 0.5 W, f = 100 Hz to 10 kHz) THD = 1% typ (Po = 3 W, f = 70 Hz to 40 kHz) • Internal each protection circuits Surge protection circuit (more than 50 V) Thermal shut-down circuit Ground fault protection circuit Power supply fault protection circuit • Low external components count HA13119 Absolute Maximum Ratings (Ta = 25°C) Item Symbol Rating Unit Operating supply voltage VCC 18 V DC supply voltage VCC (DC) 26 V 1 Peak supply voltage VCC (peak) 50 V 2 Output current Io (peak) 4 A 3 Power dissipation PT 15 W 4 Thermal resistance θj – c 3.5 °C/W Junction temperature Tj 150 °C Operating temperature Topr –30 to +80 °C Storage temperature Tstg –55 to +125 °C Notes: 1. 2. 3. 4.
