TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT
MULTI-CHIP
TA8499F/FG
3-PHASE FULL WAVE BRUSHLESS DC MOTOR DRIVER IC FOR
CD/DVD-ROM DRIVES
This 3-phase, full-wave, brushless DC motor driver IC has been developed
for use in CD/DVD-ROM drive spindle motors. The TA8499F/FG contains in
its upper stage a discrete power transistor (P-ch-MOS) and uses direct PWM
control system, which enables the IC to provide superior thermal efficiency.
Furthermore, the multi-chip structure of this device facilitates dispersion
of the heat generated inside the package, making it possible to suppress
heat concentration.
FEATURES
Multi-chip structure (3 2SJ465 chips built-in)
Direct PWM control system
Built-in current limiter : ILIM = 0.8A(typ.) (at RF=0.33 )
Built-in reversing brake/short brake functions
FG signal output (using hall element output signal)
Built-in hall bias
Built-in thermal shutdown circuit
Package : MFP-30
The TA8499FG is a Pb-free product.
The following conditions apply to solderability:
*Solderability
1. Use of Sn-37Pb solder bath
*solder bath temperature = 230C
*dipping time = 5 seconds
*number of times = once
*use of R-type flux
2. Use of Sn-3.0Ag-0.5Cu solder bath
*solder bath temperature = 245C
*dipping time = 5 seconds
*number of times = once
*use of R-type flux
