BH6519FS

00W137A 4-channel PWM driver for CD, MD player BH6519FS Description 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. 13.6±0.2 32 7.8±0.3 5.4±0.2 17 Dimension (Units : mm) 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 Applications CD, MD players Absolute Maximum Ratings (Ta=25˚C) Parameter H bridge supply voltage Control circuit supply voltage Pre-driver supply voltage Driver output current Power dissipation Operating temperature range Storage temperature range ∗Derating : 6.8mW/˚C for operation above Ta=25˚C 70mmx70mm, t=1.6mm, glass epoxy mounting. 1 1.8±0. 1 16 0. 1 1 0.8 0.36±0. 1 0.3Min 0. 15 SSOP-A32 Symbol VM VDD VG (2pin) Io Pd Topr Tstg Limits 9 9 12 1000 850 ∗ Unit V V V mA mW –40 ~ +85 –55 ~ +150 ˚C ˚C Recommended Operating Conditions (Ta=25˚C) Parameter H bridge supply voltage Control circuit supply voltage Pre-driver supply voltage Pulse input frequency Symbol VM VDD VG(2pin) fIN ∗ Min. 1.6 2.7 VM+3.0 – Typ. 5.0 3.0 10 176.4 Max. 5.5 5.5 11.5 200 Unit V V V kHz ∗When the built-in charge pump is not used.
