4-channel PWM driver for CD
and MD use
BH6512FS / BH6513FS
The BH6512FS / BH6513FS are 4-channel PWM drivers for driving the motors and actuators in CD and MD players.
MOSFET output stages are employed to keep power consumption down, and a charge pump circuit is included to multi-
ply the VG voltage.
FApplications
CD and MD players (portable units)
FFeatures
1) Four power MOS H-bridges.
2) Charge pump ( 3).
3) PWM input.
4) Low on-resistance.
5) Low power consumption.
6) Compact SSOP-A32 package.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
