BA6852FP

Motor driver ICs Spindle and loading motor driver for PD BA6852FP The BA6852FP is a motor driver IC developed for use in PD, CD-ROM and DVD applications. In addition to having a conventional spindle motor driver, it includes a reversible motor driver for use with loading motors to allow easy system construction. FApplications PD, CD-ROM and DVD. FFeatures 1) Power save circuit (three-level switch) allows FG output in power save mode. 2) FGSW allows selection between either three-phase composite output or single-phase output for the FG output. FAbsolute maximum ratings (Ta = 25_C) 3) The output voltage for the loading motor driver can be set using the Vref pin. FRecommended operating conditions (Ta = 25_C) 792 Motor driver ICs FBlock diagram BA6852FP 793 Motor driver ICs FPin descriptions BA6852FP 794 Motor driver ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C, VCC = 5V, VM1 = 12V, and VM2 = 12V) BA6852FP 795 Motor driver ICs BA6852FP FMeasurement circuits (1) Measurement circuit resistance (2) Input / output table Note: Forward EC < ECR Reverse EC > ECR Input voltage H = 2.6V M = 2.5V L = 2.4V 796 Motor driver ICs (3) Measurement circuits ICC1 BA6852FP ICC2 ICC3 : Ammeter A1 value IPS1 = 150µA H1*, H2*, H3* = VCC / 2 (V) H1), H2), H3) = VCC / 2 ) 0.1 (V) : Ammeter A1 value PS = OPEN H1*, H2*, H3* = VCC / 2 (V) H1), H2), H3) = VCC / 2 ) 0.1 (V) : Ammeter A1 value IPS3 = 150µA H1*, H2*, H3* = VCC / 2 (V) H1), H2), H3) = VCC / 2 ) 0...
