99W138A 6-channel Driver with 3.3V Regulator BA5801FS Description Dimension (Units:mm) The BA5801FS is a 6-channel BTL driver for the actuator and motor driver of a CD player. Three channels include internal filters which allow for direct coupling of the digital servo LSI PWM output, without the need for any external components. Since power supply terminals of 2-channel Loading driver are separated, It can be operated by only Loading driver. 22.0±0.2 28 0.3Min. 4.0±0.2 13.4±0.3 11.4±0.2 54 0.15 ± 0.1 27 0.15±0.1 6.0±0.2 0.1 2.2±0.1 1 Features 0.8 0.36±0.1 1) 6-channel BTL driver (2-channels Loading Driver.) includes 3.3V regulator (PNP-Tr is needed outside.) 2) Three channels include internal filters which allow for SSOP-A54 direct coupling of PWM output. 3) Filter constant can be variable by external RC. 4) 1-channel includes operational amplifier (input) 5) Loading driver can be operated by only LDVcc(Pin.51,Isolated power supply) since its structure is different from other blocks. 6) Loading driver output can be set up by voltage establishment terminal. 7) By separating Vcc into Pre and Power makes for improved power efficiency. 8) Driver mute function(4-channels except loading and regulator mute) 9) Thermal protection circuit built-in 0.1 Applications CD, Video-CD Absolute Maximum Ratings (Ta=25˚C) Parameter Symbol Supply voltage VCC Power dissipation Pd Limits Unit V 18 1.92 * W Operating temperature range Topr –35 ~ Storage temperature range Tstg –55 ~ +150 +85 ˚C ˚C *Derating: 15.36mW/˚C for operation above Ta=25 ˚C.
