Ordering number : ENA0816 Monolithic Linear IC LA6565VR Five-Channel CD Actuator Driver (BTL: 4 channels, H bridge: 1 channel) Overview The LA6565VR is a four-channel BTL plus one-channel H bridge actuator driver developed for use in CD and DVD drives. The BTL driver channels 1 and 2 include built-in operational amplifiers allowing the LA6565VR to support a wide range of applications. Functions and Features • Five power amplifier channels on a single chip (Bridge connection (BTL): 4 channels, H bridge: 1 channel) • IO max: 1A • Built-in level shifters (except for the H bridge channel) • Muting circuits (output on/off, two systems) (The muting circuits operate for the BTL amplifiers. They do not apply to the H bridge or regulator circuits.) • Built-in regulator (Uses an external PNP transistor and is set with an external resistor.) • Output voltage setting function (loading driver) • Built-in independent operational amplifiers • Thermal shutdown circuit Specifications Maximum Ratings at Ta = 25°C Parameter Supply voltage Symbol Allowable power dissipation Pd max Maximum output current IO max Maximum input voltage VINB MUTE pin voltage Conditions Ratings VCC max Unit 14 V Independent IC 0.55 W Mounted on a specified board 1.70 W For each of the channel 1 to 4 and H bridge outputs VMUTE 1 A 13 V 13 V Operating temperature Topr -30 to +85 °C Storage temperature Tstg -55 to +150 °C * Mounted on a specified board: 76.1mm×114.3mm×1.6mm glass epoxy Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.).
