1 / 5 page ICs for Compact Disc/CD-ROM Player 1 AN8497SA 3-channel linear input PWM driver IC s Overview The AN8497SA is a PWM output 3-channel driver IC supporting linear inputs, and best suited for an actuator and a motor drive for CD-ROM and DVD-ROM. Due to its linear input, a conventional system can be used only by replacing a driver. And, due to an adoption of PWM output, you can reduce considerably power consumption compared with a conventional driver. Further a space saving surface mount package is adopted thanks to its low thermal generation. s Features • Maximum 64% reduction of power consumption compared with a conventional linear 3-channel driver IC • Free gain setting by an external resistor due to voltage feedback • Standby function available (standby current < 20 µA) • Only for supply voltage 5 V • Phase compensation function s Applications • Optical disk drive s Block Diagram Unit: mm SSOP032 P-0300 116 (0.5) (0.625) 32 11.0±0.3 17 0.65 0.3 +0.10 –0.05 0.2 +0.10 –0.05 Seating plane H bridge H bridge H bridge V/I V/I V/I Pre- driver Pre- driver Pre- driver Standby (full circuit) ABS ABS ABS Logic Logic Logic TSD VREF detection SVDD detection Charge pump Triangular wave oscillator |
