BA5994FM

99W139A 4-Channel BTL driver BA5994FM Description The BA5994FM is a 4-channel BTL driver for an actuator and motor driver of CD/CD-ROM. (Inputs for the driver connect to an operational amplifier and it is compatible with various applications.) Channel 2&3 include a short-brake function. Dimension (Units:mm) Features 1) 4-channel BTL driver 2) Wide dynamic range (4V typical at PreVcc=12V, PowVcc=5V, RL=8Ω) 3) Built-in thermal shut down circuit 4) Separating Vcc into Pre and Power (Power divides into Channel1&2 and Channel 3&4) makes for improved power efficiency, by a lower supply voltage drive 5) Mute operated individually with Channel 4 and Channel 1&2&3 6) All channels are mute in standby mode 7) Suitable for low operation voltage DSP by wide dynamic range pre operational amplifier. 8) Built-in short-brake circuit (Channel 2&3) HSOP-M28 Applications CD, CD-ROM Absolute Maximum Ratings (Ta=25˚C) Parameter Supply voltage Power dissipation Output current Operating temperature range Storage temperature rang Symbol PREVcc, POWVcc Pd IOMAX Topr Tstg Limits 13.5 2.2 1 -35 ~ -55 ~ *1 *2 Unit V W A ˚C ˚C +85 +150 *1 On less than 3% (percentage occupied by copper foil), 70mm 70mm, t=1.6mm, glass epoxy mounting.
