TA8490F Datasheet (Toshiba Semiconductor) - 3-PHASE FULL WAVE BRUSHLESS DC MOTOR DRIVER

TA8490F, 3-PHASE FULL WAVE BRUSHLESS DC MOTOR DRIVER

This IC is a 3 *phase, full *wave brushless DC motor driver of the current *control / current *drive type.

It contains in its upper stage a PNP discrete power transistor, which, because of the Multi *Chip Package (MCP) structures provides high torque and thermal ef

TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT MULTI CHIP TA8490F TA8490F 3 PHASE FULL WAVE BRUSHLESS DC MOTOR DRIVER IC FOR CD ROM DRIVES This 3 phase, full wave, brushless DC motor driver IC has been developed for use in CD ROM drive spindle motors.

The TA8490F contains in its upper stage a discrete power transistor which, thanks to its low saturation characteristic, enables the IC to provide superior thermal efficiency.

Furthermore, the mu
