5 Channel Driver for with Regulator
BA5960FS
Description
The BA5960FS is a 5-channel Driver (4-channel
BTL and 1-channel Loading driver) for an actuator
and motor. Since the operational amplifier and
variable regulator are built-in, it can be compatible
with various applications.
Dimension (Units : mm)
Features
1) 5-channel driver (4-channel BTL driver
and 1-channel Loading driver)
2) Built-in thermal shut down circuit
3) The power supply is divided in 4 systems
4) Incorporates an operational amplifier.
5) Built-in stand-by function
6) Built-in variable regulator
7) Wide dynamic range
(5.4V typical at PreVcc=8V, PowVcc=8V, RL=8 Ω )
8) Mute operated individually Channel-1&2, Channel-3, Channel-4
9) Input pins consist of (+) and (–), therefore various input types
are available such as differential input.
10) Built-in brake function (Loading driver)
11) Output voltage can be set up by voltage establishment terminal.
