4-channel PWM driver for CD, MD player
BH6519FS
Description
Dimension (Units : mm)
The BH6519FS is a 4-channel PWM driver developed
for both motor and actuator driving functions in CD and
MD players. The device requires lower power consumption
due to the adoption of power MOSFET in the output.
Features
1) Built-in 4ch power MOSFET H bridge
2) PWM input
3) Built-in charge pump circuit for VG step-up
4) ON resistance 1.2Ω(Typ.)
5) Built-in thermal shut down circuit
6) Low power consumption
7) Small SSOP-A32 package
