POWVCC2 PREGND 1.65V DatasheeDatasheett 4ch System Motor Driver IC BD8229EFV General Description Key Specifications BD8229EFV is a 5-input, 4-output, BTL driver developed for PRE Part Power Supply Range: 4.5V to 14V driving Spindle motor, Sled/Loading motor and actuator coil. DC Motor System Power Supply Range: The hysteresis comparator for reset is built-in, so the 4.5V to V V PREVCC number of parts can be reduced when designing a set. Actuator System Power Supply Range: 4.5V to V V PREVCC Operating Temperature Range: -40C to +85C Features 4CH BTL Driver Wide dynamic range Package W(Typ) x D(Typ) x H(Max) (VPREVCC=VPOWVCC=8V,RL=8, 6.0 (Typ)) Built-in thermal shut down circuit Separate VCC into Pre and Power (Power divides into CH1/2 and CH3/4), which can improve power efficiency Switches CH2 input by Control input terminal (CNT) Incorporates mute function by CNT terminal and MUTE terminal Built in hysteresis comparator for reset Applications Car Audio HTSSOP-B24 7.80mm x 7.60mm x 1.00mm Typical Application Circuit RSTDET RESET Output BIAS PREVCC MUTE SP IN SL / LD SL IN LD IN ACT IN ACT IN 24 23 22 21 20 19 18 17 16 15 14 13 20k 20k 47k 47k 20k PREGND PREVCC CNT MUTE BIAS 100k 100k 100k 47k 47k 1.25V T.S.D LEVEL LEVEL LEVEL LEVEL SHIFT SHIFT SHIFT SHIFT POWVCC2 POWVCC1 POWGND1 POWGND2 CH1 CH2 CH3 CH4 1 2 3 4 5 6 7 8 9 10 11 12 POWVCC POWVCC M M TSDThermal Shut-Down Product structureSilicon monolithic integrated circuit This product has no designed protection against radioactive rays www.rohm.com TSZ02201-0H5H0BK01510-1-2 2015 ROHM Co., Ltd.
