BA5994FM Datasheet, PDF (1/2 Pages) Rohm – 4-Channel BTL driver

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)
